USPS Ground Tracking


June 28, 2023

Picture this scenario: you buy an item from the online market for a loved one’s special occasion. The seller sends the package via USPS (U.S. Postal Service) and informs you that it should be delivered three days after shipment.

Three days later, you have yet to receive the item, and you don’t know its whereabouts or what happened to it — whether it got lost or stolen.  

To make matters worse, the USPS system notified you that the parcel had already been “delivered.” Understandably, this situation can be pretty upsetting. 

Fortunately, USPS Tracking lets you monitor ground and international packages’ movements, so you don’t have to get all anxious regarding their delivery statuses.

If you want to know your parcel’s status, contact USPS via phone or email or request information at your local post office.

Visit to search for local post offices. This website offers a tracking tool for and provides crucial information regarding 31,330 post offices Los Angeles, Dallas, Chicago, Miami, New York, and other cities in the United States.

What Is USPS Tracking?

The United States Postal Service (USPS) features a tracking service that you can use to monitor the real-time status of your sent packages, letters, and other shipments.  

You can purchase USPS Tracking service on the USPS website to check your package’s latest status.

USPS Tracking consists of the following:

  • USPS package status: This part indicates your shipment’s status like “out for delivery,” “alert,” “in transit,” or “delivered.”
  • Tracking history: This record shows your package’s status and your shipment’s relevant historical information from origin to destination.

What Is USPS Ground Service?

USPS Retail Ground service is ground shipping for thick envelopes, packages, and tubes (with a maximum weight of 70 pounds) that don’t have to be delivered using the First-Class Mail service.

What Is USPS Parcel Select Ground?

USPS offers Parcel Select Ground, an affordable delivery service for large or heavy shipments. Customers who buy this mail class can send packages weighing up to 70lbs. Rates depend on the mailpiece’s dimensions, weight, and delivery distance.

How To Use Parcel Select Ground

This USPS service has five unique variants with particular requirements and standard rates. Here are the five service options:

  • Parcel Select Ground mainly targets online shipping clients with no minimum package order requirement.

USPS Parcel Select Ground is a convenient option for retailers transporting heavy or large packages under 70 pounds cheaply.

Delivery Areas For USPS Parcel Select Ground

How USPS Parcel Select Ground Rates Are Calculated

USPS Parcel Select Ground rates vary according to delivery distance, shipment weight, and box dimensions.

Rates begin at $6.99 for the zones or regions closest to your starting address, then gradually rise the further away the package’s delivery address.

Delivery Times For USPS Parcel Select Ground

Parcel Select shipping can take two to eight days. Suppose you’re delivering to remote areas of faraway regions like Alaska or Hawaii. In that case, your delivery time is likely to be longer.

Restrictions On USPS Parcel Select Ground

The maximum package weight for domestic deliveries sent via Parcel Select Ground is 70lbs, and the combined length and girth should not exceed 130”.

Different USPS Status Meanings 

You’ll see tracking status notifications when checking your package’s progress on the USPS website occasionally. Below are a few standard USPS tracking updates and their meanings.

    • Acceptance at destination”: The goods have arrived at the specified USPS processing center or post office.
    • Accepted at USPS facility”: USPS picked up the package at the USPS facility with the appropriate ZIP code. 
  • In-Transit:  This notification indicates that the package is coming to the recipient’s address. “In-transit” shows that USPS is processing or transporting your parcel to a post office.

More tracking information will be available when the package is ready and out for delivery. For example, you could receive an “Arriving Late” notification about a possible delay in your package’s delivery.

  • Out for Delivery: This notification means that USPS has dispatched the package to arrive on the agreed-upon delivery date.
  • Delivered: A “Delivered” status update means your parcel has reached the recipient’s address. This notification shows the recorded time, the shipping address, and the delivery date.

What Does A USPS Tracking Label Look Like?

Preprinted USPS Tracking labels include a peel-off strip at the bottom that can be used for records and tracking.

USPS Tracking Retail Label

The USPS tracking number is a sequence of numbers under the barcode.

Label 400, USPS Tracking Label, Front

Retail Systems Software (RSS) creates barcodes for Label 400 customers.

However, an internal-only version of USPS Tracking, called Label 888, has replaced Label 400.

Label 888 is not for sale to the general public but is available for commercial use.

What Is The Usual Format Of The USPS Tracking Numbers?

The USPS tracking number format typically consists of 20 to 22 digits with no letters or special characters — for instance, 9242 3847 3638 30000000 43.

USPS Text Tracking is a feature that customers can use to get shipment status notifications via text message. Standard messaging and data rates apply to this service.

USPS Text Tracking From Your Phone

To monitor shipments on your phone, text 2USPS (28777) using your USPS tracking number as the subject line. USPS sends you a text message detailing your item’s tracking information.

You can text your tracking number plus a keyword to 28777. Keywords allow USPS to provide you with the information you need.

For instance, the keyword “DND” informs you of every delivery attempt. “Pickup” or “UP” also tells you that the package is available for pickup.

You can sign up on USPS’ website to receive Text Tracking using your package’s tracking number. The following Text Tracking features are available on the USPS website:

  3. Read and agree to the terms and conditions, and click the “Continue” button to submit your Delivery Instructions request.

Which USPS Services Offer Tracking?

Most USPS services include Priority Mail Express and Signature Confirmation package tracking features. Some services let you monitor packages for free, while others charge a fee — meaning you’d have to pay extra.

If you use USPS to ship internationally, remember that only specific packages are trackable outside the U.S. 

Each country has its scanning resources and agreements. These differences can prevent you from tracking your package despite having a tracking number.

USPS Tracking Statuses

Again, you’ll see tracking status updates when you check your package’s status on the USPS site. Here are some typical USPS tracking reports and their meanings.

USPS Pre-Shipment

The following are two pre-shipment notifications you might receive:

  • “Not trackable”: No tracking information is available since USPS hasn’t reviewed the shipping label yet.
  • “Label created, not yet in the system”: The label was already generated, but USPS has yet to scan it into the system. 

USPS In Transit To Next Facility

This status message indicates that your parcel will be at the next USPS shipping facility. The package moves through various warehouses until final delivery. 

Out For Delivery

This notification indicates that USPS has dispatched the package for delivery to arrive on the scheduled delivery date.


A “Delivered” status indicates your package has arrived at its intended destination. This notification includes a time stamp, the destination address, and the delivery date.

Sometimes you’ll receive a more detailed delivery update like “Delivered to Agent.” This notification means USPS handed the package to an authorized representative at home or work.


An “alert”  may include the following things:

  • Awaiting delivery scan”: An expected delivery event has yet to happen despite the package being marked as “Out for Delivery.”
  • Unable to deliver; problem with address”: USPS had trouble sending the item due to incorrect address information.
  • Refused”: The recipient refused the parcel upon delivery.
  • Dead Mail” or “Sent to Recovery Center”: USPS cannot ship, forward, or retrieve the package, so it goes to the Mail Recovery Center.
  • Forwarded”: The recipient has an existing forwarding order on record, and USPS redirected the parcel to the new address.

What Does Return To Sender Mean?

Here are some notifications regarding delivery attempts that are related to the “return to sender” status:

  • Addressee unknown”: There is no known recipient at the address mentioned in the package.
  • No such number”: An address element, like an invalid apartment number, lacked crucial information.
  • Insufficient address”: The address has insufficient details to allow USPS to ship the package.
  • Vacant”: The residence or building has no occupants.
  • Moved, left no address”: The recipient just relocated without listing a forwarding address.
  • Forward expired”: The recipient’s forwarding order isn’t valid anymore as it has expired.
  • Unclaimed” or “Unspecified”: The parcel returned to the sender for indeterminate reasons.

Other Tracking Statuses

Here are some notifications you might get regarding your package’s delivery attempts.

  • Held at post office customer request”: The designated post office retains the package to fulfill the recipient’s request.
  • Receptacle full” or “Item oversized”: There was no extra space in the delivery receptacle, or the item was too large to fit.
  • No access”: The USPS agent could not reach the delivery address, such as a gated neighborhood requiring an access code.
  • No secure location available”: No package delivery place is considered safe. Also, nobody informed USPS to “leave if there is no response.”
  • Receptacle blocked”: Physical constraints restricted access to the receptacle.
  • No authorized recipient available”: No recipient could accept the package (typically for packages with Signature Confirmation service).

U.S. Mail Service Delivery Tracking

Although most U.S. Mail service products come with a tracking number, it is only the case with some products.  

Therefore, as a buyer, you must ensure the seller did not use a product without tracking features. Otherwise, you would have no clue about your item’s delivery status.

How Does U.S. Mail Service Tracking Work?

Your trackable item’s label gets scanned repeatedly throughout mail processing, whether USPS has it or one of its partner shipping companies does.

Tracking can begin once the sender or their shipping partner notifies you electronically when to expect the package.

How To Track U.S. Mail Service Package

As mentioned above, USPS offers many tracking options. One of the easiest ways to track your order is to visit USPS’ online platform ( and use your tracking number.

Users can see a photo of their item when they log into their USPS account and visit the Informed Delivery dashboard. Informed Delivery also allows the customer to sign electronically after receiving the package.

Where Is The Tracking Number On the U.S. Mail Service Receipt?

Tracking numbers are easy to locate since they only contain digits. But some people might need help finding the tracking number on their USPS receipts. 

You can find your tracking number on the post office shipping receipt. You can also get it on your package receipt if you add insurance from USPS. 

What Does “Alert” Mean On a Tracking Status?

As indicated above, an “alert”  could mean the following things:

  • “Awaiting delivery scan”
  • “Dead Mail” or “Sent to Recovery Center”
  • “Unable to deliver; problem with address”
  • “Refused”
  • “Forwarded”

The Meaning of “Inbound Out Of Customs” 

If you’re expecting an overseas package, getting this notification means that U.S. Customs has handed your package over to USPS for delivery.

In contrast, “outbound” means your parcel has passed U.S. Customs and is ready to be delivered to another country.

What Does Customs Do?

In cross-border shipping, customs clearance refers to processing and clearing items through customs based on a country’s laws. This process involves paying fees, taxes, or import duties.

Customs requirements and fees vary depending on the product you’re sending and the country you are shipping to and from. 

So when sending a package from the U.S., the appropriate customs authority in the region charges you according to the value of the item you’re sending.

Does The Customs Clearance Process Work?

Customs officers inspect all items arriving in the country and apply additional fees if necessary. Even if you mark your item as a gift on your customs invoice, it still has value, and customs officers must inspect it.

To ensure your shipment clears customs with minimal or no issues, you must specify the exact contents of your parcel.

This breakdown should include the correct value of each item and your recipient’s contact information. Incorrect or deceptive customs information could result in delays, higher charges, or returned packages.

Package Shipped By U.S. Mail Service Shows No Tracking Information

While USPS offers delivery confirmation, some mailing services don’t enable tracking features. So it’s typical for some of your items shipped via USPS to have little or no tracking information.

USPS automatically scans a parcel with delivery confirmation when it arrives at the post office and when it gets delivered. This service doesn’t include pickup scans or information showing that the courier sent your package.

What Are the Reasons Behind Tracking Not Updating?

Here are four reasons why USPS Tracking does not update:

  • Delayed courier: The carrier may be dealing with delay-causing issues on its side, resulting in scans taking longer than usual. This delay can lead to your package’s tracking information not updating.
  • The barcode is broken or unscannable: Interfering with the device’s operation, a broken barcode can appear unreadable to the scanner.
  • The package is not scanned: Your item’s tracking information requires scanning barcodes to reflect shipping updates. However, USPS may have missed scanning the barcode for some reason. This failure to inspect and record explains why your package’s status isn’t updating.

Sometimes, shipments must pass through multiple facilities and be scanned numerous times before reaching their destination. With more stops, your item is more likely not to be reviewed.

  • Weather situations are unfavorable: Weather often causes shipment delays, which can be why your tracker isn’t updating. For instance, the plane carrying your package might’ve gotten stuck at the airport due to bad weather.

U.S. Mail Service Delayed Mail And Packages

When your mail or package gets rerouted or delayed, USPS offers several options to help monitor your item’s status in the mail stream.

For instance, USPS’ delivery standards can indicate how many days you should wait before contacting USPS to inform them of delayed delivery.

USPS’ mail volume changes daily, so the company cannot always ensure delivery on schedule 100% of the time. 

Still, USPS is committed to accomplishing all shipments by 5:00 PM, local time, from Monday to Saturday, unless delivery is slow or severe weather, traffic, or natural emergencies occur.

What To Do When My USPS Package Is Delayed?

It can be a hassle to lose a package or mail. Whether you’re the sender or recipient, you lose time and money. Fortunately, you can file a formal search request at USPS for delayed shipments.

U.S. Mail Service Package Not Moving for a Week, a Month, or Has Completely Stopped

USPS can temporarily experience a surge in deliveries. But while the company strives to handle packages quickly, some parcels can take longer to process than usual.

While monitoring your shipment, you may see an “in transit” status on your item. This notification indicates that your package is heading to its destination. Still, the status can suggest that the shipment has yet to be scanned.

Meanwhile, a non-updating tracking status could also mean that the truck delivering your parcel broke down or got delayed due to inclement weather.

U.S. Mail Service Delivery Hours

USPS makes it a policy to deliver mail and packages by 5:00 PM local time from Monday to Saturday. But since the courier does not guarantee delivery times, packages may arrive at their destination after 5:00 PM.

U.S. Mail Service Sunday Delivery and Saturday Delivery Hours

USPS delivers on weekends, but schedules differ depending on your mail class or service.

Does U.S. Mail Service Deliver On Saturdays?

USPS delivers on Saturdays, with delivery time varying based on where the package is along the delivery route. 

Postmen’s Saturday shifts are the same as their Monday to Friday schedule. They make rounds to deliver packages from 9:00 AM to 5:00 PM, whatever the delivery service.

Still, inclement weather and high holiday demand can delay your mail delivery.

Does U.S. Mail Service Deliver On Sundays?

USPS delivers on Sundays for Priority Mail Express, Priority Mail, and First-Class Package Service.

Priority Mail Express charges a $12.50 rate for Sunday delivery. Meanwhile, First-Class Package service and Priority Mail only provide Sunday delivery for major metro areas.

Most USPS post offices don’t operate on Sundays. Although most USPS processing and distribution centers are open on this day to assist with shipping, these facilities are not accessible to the public.

USPS has made a few changes to its international service options, which are worth noting for those seeking USPS services.

What Is The United States Postal Service (USPS)?

USPS is the only agency with a delivery service that can reach every location in the U.S. The organization does not receive tax dollars for operating costs and depends on the sale of postage, services, and products to fund its operations.

USPS prides itself on having 34,000 retail locations and one of the most frequently visited federal government websites ( 

Additionally, USPS delivers 48% of the world’s mail, giving the agency a $71 billion annual operating revenue.

USPS Tracking FAQs

  1. Can I track the USPS truck?

No. You cannot track the USPS delivery truck, but you can monitor your parcel’s latest location using USPS tracking.

  1. I’ve received my packages, but U.S. Mail Service tracking is still not updating. What should I do?

After a post office employee scans your parcel, the tracking system can take up to 24 hours to update the ticket number.

Just ensure that the tracking number you use is correct. You might not see your package’s tracking information because you entered the incorrect number on the USPS Tracking page.

  1. What is the USPS Click-N-Ship service?

USPS offers this service as a prepaid system for shipping mail. With Click-N-Ship, customers can make prepaid shipping labels on white paper, which they can later use to ship their mailpieces. 

  1. What should I do when a parcel gets stuck in customs?

Getting parcels stuck in customs is very frustrating. But during times like these, you can either wait it out or follow the given steps:

  • Contact the seller who shipped you the item you ordered: Confirm if the person who delivered your parcel has the necessary paperwork and documents to expedite customs processing.
  • Check if you have unpaid taxes: Some nations impose specific tax requirements before you can ship packages.
  • Contact USPS: USPS can speed up custom processing but might charge extra for this premium service.
  • Wait: If you’re sure you did everything right, just wait for the package to be cleared.
  1. What is USPS interception?

USPS Interception helps clients return or reroute letters or packages to a delivery location different from the original address.  

  1. Does USPS ever make a mistake while shipping a parcel?

Like other big courier companies, USPS faces various challenges when delivering packages. Consequently, USPS may be unable to ship a parcel on time or at all.

In many cases, the mishaps aren’t the courier’s fault. For example, the sender may have provided an inaccurate or incomplete delivery address, resulting in mistaken or returned shipments.

  1. What are USPS tracking notifications?

USPS will provide notifications or updates regarding your parcel once you enter its tracking number on the USPS Tracking page or other authorized third-party websites.

You can also have USPS send updates to your mobile device via Text Tracking. This service lets USPS deliver text messages regarding your latest tracking activity.

  1. Can you track USPS Ground?

Yes. This option, which people primarily use for single-piece mailings (any mailable matter not required to be delivered via First-Class Mail), includes a free USPS Tracking feature.

  1. How do you get free USPS shipping?

You can’t get free USPS shipping but you can find free shipping materials at a USPS postal store.

  1. Can you track free USPS parcel shipments?

Yes. With services like First-Class Package Service-Commercial and First-Class Package Service-Retail, you can track shipped parcels for free.

  1. Do USPS parcels use subcontractors for their international parcels?

USPS’ policy encourages supplier diversity and innovation among prime suppliers. This rule directs the organization to subcontract with SMWOBs (small, minority, and women-owned businesses).

Couriers may subcontract final deliveries to local couriers in some countries, especially if they don’t have a working local distribution network of their own.

  1. How can I leave delivery instructions?

Using the USPS Delivery Instructions service, you can ask USPS postal employees to leave a package at a particular location at the recipient’s address. This service lets you send shipments to another site or bring the parcel to your post office.

To use USPS Delivery Instruction, do the following:

  • Log in to your account. 
  • Click the tracking results link.
  • Go to the “Change Delivery Instructions” page. If you cannot access this page, your package will likely be ineligible for the service.
  1. Where is my U.S. Mail Service package?

You can see your package’s delivery status by entering its tracking number in the USPS Tracking page’s search box.

For instance, if you get a “Delivered” notification, the tracking information will display the recorded delivery time, date, and address where USPS deposited your parcel.

  1. When will my letter carrier or mail arrive?

When checking your parcel’s status, you might also see a message regarding the expected delivery window.

 This information usually refers to a two-hour time slot when the recipient can expect to receive the package.

That said, USPS does not guarantee delivery within the indicated delivery window. Still, the recipient usually receives the parcel by the day’s end, even if the delivery does not happen within the expected window.

  1. What can I do if my mailpiece hasn’t been delivered?

Check your item’s mail class delivery standard if you have not received the mailpiece. Compare the mail class and progress to USPS Mail Delivery Standards chart.

You can access this comparison chart by entering the mailpiece’s tracking number on the USPS Tracking page and visiting the “Product Information” page.

The delivery time varies depending on the mail class. So, your mailpiece might be in transit and not necessarily lost or stolen.

For instance, Priority Mail usually completes delivery within one to three business days. If you still haven’t gotten your mail within this timeframe, it’s advisable to contact USPS customer service.

  1. How do you get your package with U.S. Mail Service delivered?

You deliver your package via the U.S. Mail Service or USPS by depositing it in a mailbox or a local post office.

Individual shippers or retail businesses do this process once or twice weekly. Larger companies like Amazon or eBay do so almost daily.

A postal worker collects the deposited package and other shipments and transports them to a USPS sorting facility.

These facilities have machines that automatically organize packages according to size and shape. Once they’ve sorted the packages, another device assigns them to the correct destinations.

USPS ground shipments typically deliver domestic shipments using trucks. Meanwhile, international shipments are more complicated as they must get clearance from customs before being sent to the destination country by ship or plane.

Upon the parcel’s arrival in the destination country, customs officials examine the package before allowing a USPS partner local courier to collect and deliver the package.

  1. Where do I discover my tracking or reference number?

Here are places where you can see your shipment’s tracking number:

  • The sales receipt if you bought insurance for your parcel
  • The confirmation email if you had your package shipped using the USPS website or an online retailer
  • The post office shipping receipt
  • The peel-off part of the USPS Tracking label
  1. How do I access tracking information?

The tracking information you can get depends on what mail class or add-on services you bought. You can monitor your package’s status using the following:

  • The USPS Tracking page
  • USPS Text Tracking
  • USPS Mobile App for Apple and Android phones
  • The USPS phone number
  1. Does USPS charge their packages by weight or size?

Yes. For instance, First-Class Mail determines the shipping price by measuring weight and shape.

Meanwhile, Priority Mail considers the size, weight, and distance the package travels.

Priority Mail pieces exceeding one cubic foot are subject to “dimensional weight pricing.”

  1. Do I have to pay extra costs for USPS’s delivery instructions service?

Whether or not you pay extra depends on the delivery instruction service you requested. Basic instructions that do not require an additional fee include the following:    

  • Delivery of the parcel at a particular area on your property (e.g., front door and backyard)
  • Delivery of the package at a nearby post office 

In contrast, the following parcel delivery instructions will cost you extra:

  • Redirect your package delivery to a new residential address outside the carrier’s original route with a different ZIP code.
  • Upgrade your delivery service to Priority Express or Priority Mail.
  • Pick up or hold the package at a post office that is different from the nearest according to your ZIP code.
  1. Will there be any email notifications on my USPS delivery instructions request?

Whether or not you will receive email notifications depends on the option you choose when setting up your delivery instructions. 

You can receive these email notifications:

  • You will get a confirmation email for successfully submitted requests or delivered parcels.
  • Suppose you set up a delivery instruction requiring an extra payment, and the actual postage costs more than the estimated postage indicated at your request. In that case, you will also receive a confirmation email.
  • You will get a new USPS tracking number for items that need repackaging.
  • For undeliverable products, you will receive an email indicating the reason for the non-delivery.
  1. What do I do if my USPS package is missing?

You can ask for a Missing Mail search if you think your package was stolen or lost. 

You must give the following information when submitting a request:

  • Sender’s shipping address
  • Recipient’s shipping address
  • Your item’s description, like the color, brand, size, or model, if applicable
  • Photos to help the USPS staff recognize the item
  • Size and type of envelope or box used
  • Identifying information, such as tracking number, Click-N-Ship label receipt, or the delivery date on your mailing receipt
  1. What is the expected delivery window with USPS tracking?

As indicated above, the estimated delivery window refers to the two-hour time slot you can expect to receive your USPS package.

  1. How do I add USPS tracking to my parcels to be shipped out?

You can add USPS tracking to your shipment by getting a tracking label on your USPS package. This label contains the USPS tracking number that you can use to track your parcel. 

Follow these instructions for adding USPS tracking to your packages:

  • Post Office: If you ship your package at a post office, tracking is automatically activated after you complete the payment at the retail counter.

Upon payment completion, you must be able to check your parcel’s status using the tracking number on your USPS package’s receipt.

  • Online: Register a USPS account and print your shipping label.

Fix the label on your receipts or products. You can monitor the status of your USPS packages using your USPS account. 

If your selected service does not have a USPS tracking service, you must pay extra for the tracking feature. You will see your USPS tracking number in the proof of delivery document.
