In 2021, the United States Postal Service’s (USPS) Priority Mail service generated over $14.3 billion in shipping revenue. This service comprised most of USPS’ total income for that year, outperforming First-Class and Parcel Select services.

How do you track your domestic and international Priority Mail packages? How does USPS Tracking work? Do tracking numbers have different formats?

This article discusses these issues and tells you how to find the tracking number on your package. This article also explains the meanings of the different tracking status messages and why such statuses do not update sometimes.

When sending mail using USPS Priority Mail or Priority Mail Express, use FindPostOffice.org’s online search tool to locate a post office near you. You can also find post offices by city, state, or ZIP code to help narrow your search.

What Is USPS Tracking?

USPS Tracking checks the delivery status of your mail, packages, and consignments sent through the United States Postal Service (USPS). Upon entering your item’s tracking reference number into the USPS website’s tracking page, you can see your parcel’s latest status.

The tracking information usually has two parts:

  • USPS package status: Shows your package’s status summary, such as “In transit” or “Delivered,” and updates tracking information within 24 to 48 hours.
  • Tracking history: Provides your parcel’s current status alongside other historical data.

What Is Priority Tracking?

When you ship packages using USPS Priority Mail, your mail pieces will include tracking information. This Priority Mail tracking feature enables you and your recipient to monitor your shipment’s movements through the USPS system to the item’s destination.

How Long Does Priority Mail Take?

Who Delivers USPS Priority?

When you send an item through Priority Mail, USPS can deliver it to your post office box (P.O. box) or through a mail carrier.

USPS will not charge you extra for fuel, Saturday delivery, or residential or rural delivery when you use Priority Mail.

Does Priority Mail Automatically Come With Tracking?

Yes, Priority Mail readily comes with USPS Tracking. However, this feature is not included when you use prepaid Forever Priority Mail Flat Rate products.

How Does USPS Tracking Work?

When you send your package, USPS or one of the company’s shipping partners scans your item’s label several times during the mailstream. Tracking starts when you or a USPS shipping partner electronically notifies the Postal Service about the expected package.

Tracking continues with USPS receiving the package during transit and ends when the recipient or agent receives or picks up the item.

You can access your package’s tracking information throughout the delivery process by entering the item’s tracking number into the USPS Tracking page’s search box.

USPS Tracking Retail Label

When looking for the USPS Tracking number on your package, you should see a barcode with a series of numbers under this code. This number is your tracking number.

Label 400, USPS Tracking Label, Front

As of January 2023, USPS replaced the Tracking Label 400 with Label 888, an internal-only version available for commercial customers only. All post offices no longer offer this shipping label and have removed it from retail lobbies.

  • The confirmation email you receive from an online retailer

Suppose you want to check your shipment’s tracking information to know your package’s status. Whether you are the recipient or shipper, you can track the delivery status through the following options:

  • Accessing USPS.com’s tracking page: Enter the tracking number in the USPS Tracking service page’s search box on the USPS website.
  • Using third-party web tracking tools: Input the tracking number on third-party websites like USPS-Track.US. These sites are authorized by USPS to provide fast and safe package tracking.
  • Using USPS Text Tracking: Text your tracking number to 2USPS (28777). Standard messaging charges can apply.

  • Text your tracking number as the message’s content to 28777. The text reply should contain your item’s latest tracking information.
  • Text your tracking number and a keyword to 28777. Keywords inform USPS of the specific information you need, such as whether or not the courier has attempted delivery.

Different USPS Status Meanings

As you scroll through your shipment’s tracking information, you will likely encounter different messages summarizing your item’s delivery status. The following sections discuss the meaning of these messages.

What “In Transit” Means in the U.S. Mail Service

Your shipment is “In Transit” when the carrier has picked up and scanned your package and sent it en route to the recipient.

A shipment may be delayed if it is in transit for an extended period. Some reasons for this delay include unfavorable weather, adverse road conditions, or poor location deliverability.

What “Out for Delivery” Means in the U.S. Mail Service

This status means your package has left the courier’s facility and is heading to your recipient’s delivery address. This status should change to “Delivered” after the postal worker delivers the item to your recipient.

What “Delivered” Means in the U.S. Mail Service

If you are the mailer, the “Delivered” status indicates the courier has delivered your package to your recipient. After the item gets dropped off, the tracking information should show the delivery date and time.

What Does “Return to Sender” Mean?

This status means the courier is returning the package to the shipper. If you had sent the item, you may incur duties and taxes for the return.

Depending on the fees, you may dispose of the package at the destination country and send another one in place of the item.

“Inbound Out of Customs” Meaning

Getting this status means U.S. Customs has released your package, which should be on its way to your recipient.

If this status shows “Outbound” instead, your package has passed customs inspection and is heading to the destination country.

What Does Customs Do?

When international mail enters the United States, it passes through customs through one of five International Service Centers (ISC) in New York, Chicago, Miami, San Francisco, and Los Angeles.

ISCs dispatch and distribute international mail from designated service areas to gateway exchange offices or specific foreign countries.

Does the Customs Clearance Process Work?

As international mail arrives at an airport, ground handlers unload the receptacles containing mail and packages and take those items to the ISC. Afterward, USPS employees monitor and verify the status of these mail receptacles and make reports.

You can use these documents to instantly determine information about the mail, including when it was sent, scanned, and assigned to a specific flight from the origin country.

Other Tracking Statuses

Some status messages that may seem uncommon can appear when you check your package’s tracking information. Examples of these statuses include the following:

  • Damaged in transit: The package got damaged during delivery. You can file a claim to receive compensation.
  • Uncontrollable customs delay: The international package is held up at customs for some reason, such as having the recipient pay outstanding taxes or duties.
  • Missed “In Transit” pickup scan: The internationally routed package remains stuck “In Transit” for an extended period and then suddenly updates to “Delivered.”

“My Package Shipped by U.S. Mail Service Shows No Tracking Information”

It is normal for mail pieces shipped through USPS to have little or no tracking information. Some USPS services, such as First-Class Mail, do not include the tracking feature and instead have delivery confirmation.

With delivery confirmation, such as USPS’ Proof of Delivery service, you receive an email letter containing the following details:

  • Your shipment’s delivery information
  • Recipient’s name
  • Tracking number
  • Image of the recipient’s signature
  • Printed name and address
  • Delivery location attribute, such as the porch or front door
  • Extra services
  • Product of mail
  • Package weight

U.S. Mail Service Tracking Not Updating

Although USPS Tracking usually works properly, there may be instances when the tracking information does not update. Some of the reasons for this situation are discussed in the following sections.

What Are the Reasons Behind Tracking Not Updating?

If your package’s tracking information is not updating, a few reasons for this circumstance can be any of the following:

  • Package barcode not scanned
  • Bad weather conditions
  • Package not scanned at intermediary stops due to unavoidable circumstances
  • Unscannable or broken barcode
  • Delay on the part of the carrier

“I’ve Received My Packages, but U.S. Mail Service Tracking Is Still Not Updating”

It is possible to receive your package without its tracking information updating, especially during the holidays when there is a package delivery rush. USPS can skip scanning to handle the increased demand in these situations.

Therefore, when USPS lags, it may forego scanning to help move the packages quicker.
