USPS GPS Tracking


March 21, 2024

On average, USPS (United States Postal Service) processes and delivers 23.8 million packages daily.

With this number, you might wonder how the carrier ensures the safe and timely delivery of those parcels.

Tracking is a tool that USPS provides its customers to help them monitor mailpieces through status notifications. 

But how does USPS tracking work when sending an item through its network? Does USPS live GPS (Global Positioning System) tracking work? 

What is the meaning of each USPS tracking message? What can you do if your package does not arrive at the recipient’s address?

This article discusses how USPS Tracking works to help you stay on top of your shipment. It also lists and explains various tracking notifications.

Does USPS Have Live GPS Tracking?

The official USPS website ( does not have any information verifying the claims of other websites that USPS offers live GPS tracking. It is unlikely that USPS offers this live tracking feature.

How Does USPS GPS Work?

USPS doesn’t offer a service titled “USPS GPS.” However, the carrier offers Informed Visibility, a feature that leverages GPS tracking information from carrier handheld scanners, allowing you to obtain shipment details.

GPS tracking enables location monitoring through the Global Positioning System, allowing people to track an object or entity remotely.

The GPS is a network of well-spaced satellites orbiting the Earth. This technology allows people with ground receivers to determine their geographic location.

USPS Test: Mailed 4 Packages With GPS Trackers to See How Quickly They Got There

Concerns about USPS package delivery reliability and speed occasionally arise, especially during the holiday season.

An experiment involving four GPS-tracked packages sent from Tampa, Florida, to Seattle and Jacksonville showed that Priority Mail and First-Class mail arrived faster than expected.

How Does USPS Tracking Work?

Suppose USPS or any of its shipping partners has your mail or package. In that case, their agents will scan the shipping label of your trackable item as it goes through the mailstream.

Generally, the tracking procedure begins when the mailpiece’s sender or USPS delivery partner notifies the system about the package’s arrival.

Automated Processing Equipment Takes Care of the Initial Tracking

The USPS automated processing and sorting equipment usually creates tracking scan events before your parcel arrives at your local post office.  

Sometimes, a USPS shipping partner offers temporary scan information while the package is within its system before the parcel arrives at a USPS facility.

Once your mailpiece reaches your local post office, subsequent scans will be conducted using handheld MDDs (mobile delivery devices).

Manual Scans Track the “Final Mile” Deliveries

GPS coordinates can usually be located within 10 meters of a particular location. The information you will get depends on the scans conducted at various delivery locations.

In 2002, USPS introduced the Managed Service Points (MSP) program to scan barcodes at your local post office (delivery unit) and particular points along your postal carrier’s route. 

The stop-the-clock (STC) scans happen during delivery or attempted delivery.  

USPS representatives use intelligent mail devices (IMDs) to scan tracking barcodes. The information taken from these scans helps measure postal service efficiency and provides users with a way to track parcels.

USPS rolled out MDDs in 2013. These devices record GPS locations along the mail carrier’s route. 

MDDs can also give GPS details even when a tracking barcode is scanned as “Delivered.”

The scans generated by MDDs are transferred to the USPS regional intelligent mail server (RIMS) network, a cloud-based system that uses GPS to provide users with updated reports.  

Recipients Can Track the Shipping Progress of Their Package

Recipients can use the tracking code generated during the shipping label creation to monitor their package’s delivery journey through the USPS network. These parcels can be tracked online or through text updates.

USPS offers product tracking and reporting (PTR) scan events as the mail or package is processed within the postal system. 

The scripted scan events give a brief description of the parcel’s status during scanning.

The Tracking System Isn’t Perfect

The USPS Tracking system has many benefits, but it is not error-free.

Package tracking depends on user familiarity, network connectivity, and customer compliance with USPS policies:

  •  Device failure can also lead to missed scans. As a result, postal workers may have to enter the data manually.
  • Network connectivity issues may delay scanning or lead to inaccurate GPS location data. 
  • Satellite signal obstructions, like tall buildings and mountains, may prevent scanned data from getting to the RIMS network.  
  • Rain can also disrupt the MDD’s laser scanner’s ability to capture the tracking barcode.

The USPS Inspector General conducted an audit in 2019 and found that a relatively small percentage of STC scans occur in the post office rather than at the delivery site.  

This info suggests some shipments were pre-scanned as delivered before leaving the post office for delivery.

How Does the USPS Shipping Process Work?

The answer to this question depends on whether you’re shipping domestically or internationally and what item you’re sending.

For instance, here’s a step-by-step guide to sending a letter or postcard abroad:

  1. Check if you can deliver your mailpiece to the recipient’s country or region.

Some services are restricted to certain locations or for a specific mailpiece type or amount. Visit the USPS’ Individual Country Listings for details on eligible countries.

Determine the available services according to what you want to send and the parcel’s endpoint. Then, narrow your decision based on price, delivery time, and product features.

  1. Select a postcard or envelope.
  2. Address your mail or package using the guidelines suggested by USPS.
  3. Calculate and apply postage.
  4. Send your mail by placing it in your mailbox, handing it off at a post office counter, or depositing it in a USPS blue collection box.

Can You Track the Exact Location of a Package?

Visit the USPS Tracking page and input the USPS tracking number on the mailing receipt or label. You must be able to check the status and current whereabouts of your USPS package.

Not Every USPS Package Can Be Tracked

Remember that not every mail or package has a tracking number. Postcards and First-Class Mail letters without additional services fall into this category. 

How Long Will USPS Keep My Delivery Records for Tracking?

As of 2023, access to tracking information regarding nonsignature items is restricted to 120 days. Tracking information for signature items is accessible for two years. 

USPS Tracking Plus can extend access to the tracking data for 6 months up to 10 years for a minimal fee.

How Can I Track My First-Class Mail Letters With USPS Tracking?

First-Class Mail does not offer USPS Tracking. 

Although First-Class Mail letters, postcards, and flats are ineligible for USPS Tracking, those items are eligible for extra features that provide barcodes for scanning. 

You can purchase these extra services to obtain specific tracking information.

How Do I Track My USPS Package?

You can monitor USPS packages through the following means:

  • Online 
  • By phone 
  • By smartphone
  • By text

What Is the Format of the USPS Tracking Numbers?

The U.S. Postal Service values transparency and accountability regarding mail and package delivery services. For this reason, the carrier operates a tracking system and generates tracking numbers for each package and mail. 

So, what does a USPS tracking number look like? 

The USPS tracking number format typically consists of 20 to 22 digits without symbols or letters. Here’s an example: 9400 3867 3858 3000 0000 43. 

These tracking codes have unique formats and characteristics, ensuring each parcel or letter is identifiable while in transit to its final destination.

USPS Tracking Number Format Examples

You can obtain a USPS tracking number by choosing one of the following postages. 

Here are a few examples of what these codes might look like:

  • Collect On Delivery Hold For Pickup: 9203 4000 0000 0134 0000 00 
  • Certified Mail: 9407 3000 0193 0000 0000 00
  • Global Express Guaranteed: 82 000 000 00

  • Priority Mail International: CP 000 011 090 US
  • Signature Confirmation: 9202 4000 0000 0060 0700 00

Where Is My USPS Tracking Number?

You can see your tracking number from these sources:

  • Your post office delivery receipt
  • Your sales receipt if you paid for insurance at the post office
  • Your email confirmation if you sent an order from

What Is USPS Interception?

For an additional cost, USPS Package Intercept lets the shipper or recipient stop delivery or reroute a letter, package, or flat that is not out for delivery or already shipped. 

Most domestic shipments with a tracking or extra services barcode qualify for Package Intercept. You can only submit a request for Package Intercept online.

Why Is Package Tracking Useful?

USPS Tracking service offers end-to-end mailpiece tracking and is available for most domestic shipments that are large enough and addressed to local places.

These locations include the following:

  • APOs (Army or Air Force Post Offices)
  • DPOs (Diplomatic Post Offices)
  • FPOs (Fleet Post Offices)
  • Destinations and ZIP codes within the U.S. territories
  • Freely Associated States

How Do I Add USPS Tracking to My Parcels to Be Shipped Out?

You can add USPS Tracking to your parcels through the following ways:

  • At a post office: USPS Tracking automatically activates once you pay the postage on your eligible mail service at the post office retail counter.

Use the tracking number printed on your mailing receipt to access shipment information.

  • Online: Sign up for a account to generate and print USPS Tracking labels, purchase mailing or shipping services, or buy stamps.

The tracking label prints the label affixed to the item and a receipt with the tracking number. 

Log into your account to check tracking information or your mailpiece’s status.

Note: When you pair a USPS Tracking package with an extra service, you can obtain proof of delivery, like a signature. 

Regardless of your chosen method — at the post office service counter or online at — you can access USPS Tracking information.

When Will My USPS Package Arrive?

Below are the expected delivery periods for different mail classes:

  • Priority Mail Express: Guaranteed one to two calendar days 
  • Priority Mail: One to three business days 
  • Package services: Two to eight business days 
  • USPS Ground Advantage: Two to five business days
  • First Class Mail: One to five business days 
  • Parcel Select Lightweight: Two to eight business days

What Should I Do if My Mail Hasn’t Been Delivered?

Say seven business days have passed since you submitted your online help request form, but your mail or parcel has yet to arrive.

You can request a Missing Mail search by providing the following info:

  • Sender mailing or shipping address
  • Recipient mailing or shipping address
  • Description of the contents, including what it is and the model, brand, size, or color, whenever applicable
  • Container size and type of envelope you chose
  • Identifying information, including USPS Tracking numbers, the mailing date on your receipt, or Click-N-Ship (CNS) label receipt
  • Photos that could help USPS recognize your item

I Haven’t Received My Package, but the Tracking Number Says It Was Delivered

There are several reasons why the USPS tracking status marks your parcel as “Delivered” even though you cannot find it.

These reasons may include placing the item in a hidden location, incorrect shipping address, misdelivery, theft, human error, technical problems, or unfavorable weather conditions.

Should I Be Worried if USPS Tracking Info Hasn’t Been Updated in 3 Days?

As shown above, the USPS may consider an item lost if tracking information has stayed the same for seven days. 

Suppose you notice your tracking number is not updating and suspect the shipment is missing. In that case, you can order a missing package search with USPS.

What Does It Mean When USPS Tracking Hasn’t Been Updated for a Few Days?

Suppose your package hasn’t been updated in a few days. In that case, there could be a scan issue or a case of temporary misplacement.

Sometimes, packages aren’t scanned at stopovers, making it seem like there’s no delivery progress. Other times, the carrier might be running late.

Check the Tracking Information to Make Sure Your Package Isn’t at a Shipping Partner Facility

The following tracking notifications indicate that your package is not within the USPS network yet:

  • “Picked Up By Shipping Partner, USPS Awaiting Item” 
  • “Departed Shipping Partner Facility, USPS Awaiting Item”
  • “Arrived Shipping Partner Facility, USPS Awaiting Item.”

Suppose the tracking message says your parcel is with a USPS shipping partner. In that case, the shipment may go through USPS once the shipping partner has at least 50 packages to drop off.

Shipping partners usually offer logistical services to retailers at USPS’ discounted Parcel Select rates and send packages out to USPS as soon as possible. 

However, it may take two to eight days before packages reach USPS.

If Your Package Is in USPS’ Possession

As mentioned, USPS provides PTR (product tracking and reporting) scan events during mail processing.

However, not every single scan will be listed in your tracking status. The scans may only be listed if they are considered “external.”

Depending on the delivery distance, the typical route of items as they move through the USPS mail stream is as follows:

  1. The sender drops off the parcel at a post office.
  2. USPS representatives transport the package to a sorting facility near the sender.
  3. The parcel is loaded onto a truck or plane for transport to another sorting facility.
  4. The package arrives at the recipient’s local post office.
  5. The last-mile postal carrier picks up the package for final delivery.

Is Your USPS Package Stuck in Transit?

There may be a lapse in tracking updates while your package is “In Transit.”

You might see an “In Transit” status if your parcel has not had a scan within 18 hours.

During this time, your item may be on a truck or plane en route to your local post office or another USPS facility.

The item may also be on a loading bay waiting for dispatch. 

Meanwhile, various factors, including the delivery distance, traffic conditions, and weather, can affect how long your item will have an “In Transit” status.

USPS doesn’t scan mailpieces while they are “In Transit” or waiting to be picked up, delivered, or processed.

If your parcel is in transit and the weather is adverse, the tracking info might indicate “Weather Delay.”

Have There Been No USPS Tracking Updates After “Arrival at Unit”?

An “Arrival At Unit” tracking scan event means your parcel has arrived at your local post office.

The clerks at the post office can sort items quickly and mark them as “Out for Delivery” by the next business day.

Suppose your package’s status shows “Arrival at Unit” for a long time. In that case, you can contact your local post office to check if there’s an issue.

Does Your USPS Tracking Say Out for Delivery, but You Still Haven’t Received It?

Say your delivery status shows “Out for Delivery,” but you haven’t received your package within the day. In that case, your USPS might return the parcel to the post office.

If a delivery problem occurs, the mail carrier or local post office may re-scan the package and upload a new status indicating the cause of the problem.

Generally, an “Out for Delivery” tracking scan event means your parcel has left your local post office and is on a postal carrier’s vehicle en route for delivery within the day.

Once a package has been scanned as “Out For Delivery,” it should mean that your package has left your local post office and is on a postal carrier’s truck on route for delivery that day. 

The USPS website says they aim to deliver everything by 5:00 PM. However, the expected delivery time may be as late as 8:00 PM (or even later in some instances).

Common Reasons Your Package Tracking Status Has Not Updated

Here are four common reasons why your package tracking status remains unchanged:

  • The shipment is in transit, so there’s no update until it arrives at the next location.
  • The package is waiting to be unloaded, loaded, sorted, or processed
  • Your postal carrier or local post office did not scan the item or had a scanner malfunction or signal disruption.
  • There’s a problem scanning the label or barcode.

Less Common Reasons Your Package Tracking Is Not Updated

Below are less likely causes of why your package tracking is not updated:

  • The package barcode or label is illegible or missing.
  • The postal carrier did not scan the barcode after a delivery attempt.
  • The package was sent to the USPS Mail Recovery Center.
  • The parcel was damaged during sorting or processing.

What Are USPS Tracking Notifications?

You can view tracking status updates for your mail or package on the USPS website anytime. These USPS tracking notifications have different meanings.

When you input a USPS tracking number onto a tracking site, you will receive relevant updates from the USPS delivery service.

What Do My Tracking Statuses Mean?

USPS offers package tracking status scans. Below are some of the most common statuses, meanings, and ways to respond to them. 

What Does the “Delivery Exception, Local Weather Delay” Status Update Mean?

A “Delivery Exception, Local Weather Delay” status update or USPS event code 57 may mean the package could not be delivered due to local weather conditions.

What Does “Alert” Mean on My Tracking Status?

An “Alert” status appears when USPS encounters an unexpected issue during the shipping process, such as a recipient’s refusal to accept the parcel or a mistaken address.

What Does the “Visible Damage” Status Update Mean?

A “Visible Damage” status info or USPS event code 12 may mean that USPS noticed and recorded a damaged delivery.

What Does the “No Such Number” Status Update Mean?

A “No Such Number” tracking notification may mean USPS will return the parcel to the sender.

This scenario might happen due to an incomplete, missing, or inaccurate delivery address, making the package undeliverable.

What Does the “Arrival at Unit” Status Update Mean?

The “Arrival at Unit” tracking message or USPS event code 07 may mean the mailpiece has arrived at the local post office on the specified date and is ready for delivery.

Generally, if the mail or package arrives before 9:30 AM, post office personnel will deliver them within the day. Parcels arriving after 9:30 AM will be delivered the next business day.

My Shipment Tracking Status Says “Delivered,” but I Can’t Find My Parcel or Mail. Where Is It?

You may encounter this situation when the USPS tracking system identifies your expected package as “Delivered” but has yet to arrive at your address. 

Several factors, including human error,  technical issues, or unfavorable weather conditions, can cause this unfortunate event.

What Does the “Customs Clearance” Status Update Mean?

USPS facilities collect postal service fees from the recipient for each item on which customs duty or Internal Revenue tax is due.

Internal postal agreements approved the postal service fee to reimburse the costs for clearing goods through customs and collecting customs duties at delivery.

What Does the Status Update USPS Package Status “Payment of Charges” Mean?

The status “Payment of Charges – Item Being Held, Addressee Being Notified” may mean the customs duty or value-added tax is due for an international mail or package. 

What Does the Status Update Pre-shipment Mean?

This notification may mean a shipping label has been generated with a USPS Tracking number. Still, USPS has yet to receive the package.

Upon the package’s receipt, USPS will process and transport the parcel to the delivering post office. The system will provide the estimated delivery date.

How Long Does It Usually Take to Deliver an International Package With USPS?

Here are the expected delivery periods for some international USPS services:

Mail ClassDelivery Time
Priority Mail International6 to 10 business days

What Is USPS Collect on Delivery (COD)?

Collect on Delivery is a service that allows the shipper to collect from the recipient money for postage, merchandise, fees, or any combination thereof. 

Each COD item has an ID (identification) number, providing delivery confirmation.

What Does USPS Signature Confirmation Mean?

This extra service can provide you with the following information:

  • The recipient’s name and signature
  • Time, date, and location of the delivery

Signature Confirmation requires the recipient (or a designated person at the delivery address) to sign for the package.

How to Send an International Mail or Package With USPS

Here are seven steps for sending an international USPS parcel or mail:

  1. Find the country you’re sending the package to in the International Mail Manual’s Individual Country Listings. The list will also inform you of what you’re not allowed to ship to the intended destination.
  2. Check which mailing option you can use based on what you want to send and where you plan to send it. Refine your decision based on price, delivery speed, and included features.
