Track Delivery of Your USPS Shipments

Suppose you own an online business selling products on Amazon or eBay and need to ship goods to your customers. When you print a USPS shipping label, you can email its tracking link information to your buyers.

Providing your clients with a USPS tracking number keeps them updated on their orders’ delivery status. Simultaneously, making your clients’ package details readily available can demonstrate excellent customer service.

“How Can I Track My USPS Parcel?”

You can track your USPS package through the USPS website or a third-party tracking site. Locate your USPS tracking number on the shipping label and enter the number into the search field.

The tracking page will then display notifications showing your package or mail’s status and updates regarding its location and expected delivery date.

“How Can I Track My International USPS Package?”

Tracking international packages works in the same way as described earlier. Some third-party tracking pages allow you to track more than one package simultaneously.

Although the U.S. Postal Service includes tracking services, other couriers subcontracted by USPS can also handle your package during delivery, especially international shipments. USPS Tracking should be able to show this information.

“How Do I Scan My Package’s USPS Tracking Code?”

Suppose you want to ship an item and scan its tracking barcode or quick response (Q.R.) code. All you should do is bring the package to your local post office, and a USPS employee will scan the code for you.

Does USPS Scan Packages for Tracking?

Whenever USPS or its shipping partners possess your item, the package’s label gets scanned several times throughout the mail stream. Tracking starts when the shipping partner or item’s sender sends USPS an electronic notification regarding the package.

How Does USPS Scanning Work?

After handing over your package to USPS for delivery, tracking proceeds with the postal worker accepting your parcel for transit. Tracking ends when the courier delivers the item or the recipient picks it up.

USPS Has Delivered Your Package Without a Delivery Status Update

Suppose your package has been delivered, but its “out for delivery” status hasn’t changed in the last few hours or days. Consider checking around your home to determine if the package has arrived. The courier may have delivered your item but not updated the status.

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

Tracking not updating is possible, especially during the holidays when there’s a rush of mail packages. In such situations, USPS can experience a slowdown.

During such events, the courier can skip scanning to help move the packages quicker. This situation can lead to your package’s tracking information not updating.

“I Dropped Off My Package, but It Still Hasn’t Been Scanned Yet”

If you ship your package with USPS through a third-party courier, it’s possible that scanning can take longer than expected. Some reasons for this delay are as follows:

  • If you drop off your package after business hours, USPS may not scan your item until the next day.
  • Your parcel may be in the queue at a USPS facility.
  • The postal workers scanning your package may not have scanned it on the day when you dropped it off.
  • The post office where you dropped off your package may not have initially scanned it due to high mail volume.

What You Can Do

If tracking information has not appeared several days after dropping your package off at USPS, consider visiting your local post office or contacting USPS customer service to ask what happened to your shipment.

Another way to address this issue is to file a missing mail search request to prompt USPS to update your package’s tracking scans.

Possible Reasons Behind USPS Tracking Not Updating

Your package’s tracking information may not update for numerous reasons. Some of these reasons may be within the courier’s control, while others may be due to external factors. The sections below briefly discuss these reasons.

Bad Weather Conditions Can Disrupt USPS Tracking

Weather can slow down your courier and cause your mail or package to take longer to reach the next station. For example, heavy rains or snow can prevent the delivery truck from leaving the facility.

Bad weather can also damage the tracking barcodes, rendering them unreadable to the scanner and preventing the status from getting updated.

Package Not Scanned or Updated

The tracking barcode can get torn or smudged during handling, causing the scanner to be unable to read it. Although the post office can manually input barcodes, there are times when shipping schedules are tight, and the postal worker can miss the scan.

Package Not Moving (Yet)

During peak periods, a USPS facility can operate at such a high capacity that it struggles to keep up with the considerable mail influx.

This increase in mail volume can slow the mailing process, causing your package to get stuck in that facility longer than expected.

Package Lost Somewhere

Despite USPS’ best efforts to deliver your package safely, there’s still the possibility that mail can get lost somewhere along the way. For example, your mail can fall off a truck or conveyor belt.

Update Delayed by the Carrier

Sometimes, the carrier’s circumstances can cause your package’s tracking status to take longer to update. For instance, the person scanning has finished their shift before scanning your item. The other personnel might put your package in the truck or return it to the distribution center.

Package Has Been Delivered Without a Delivery Update

As mentioned, the courier can deliver your package without updating its tracking status. For example, the recipient receives the box, but the tracking system takes too long to change your item’s delivery information.

“What Do I Do if My USPS Tracking Number Isn’t Updating?”

Suppose you want to know your parcel’s delivery status but can’t get real-time information because the tracking number isn’t updating. In this case, the following sections can help you track packages whose statuses don’t update.

Check Your USPS Tracking Number

As mentioned, you can find your package’s tracking number on the shipping receipt you receive when mailing your item to the post office. Input this number in the search box on the USPS website.

You can also find the tracking number in your confirmation email and the peel-off portion of your USPS Tracking label.

Contact USPS Customer Service

When you call USPS customer service and speak to a representative, the tracking information they will see is the same as what appears on USPS Tracking.

However, if you still want to speak with a representative regarding another issue with your package, call 1-800-222-1811.

Go to the Post Office

If you need help using the tracking number or calling USPS customer service, visit your local post office. The postal staff will do what they can to assist you regarding package tracking.

Wait a Few Days to Get Tracking Details

If you’re expecting a non-urgent shipment whose tracking status isn’t updating, waiting a few days may not be a big deal. Expect some delays if the mail class used to send your item isn’t guaranteed.

However, if your parcel is time-sensitive, you may need to contact USPS customer service for assistance.
