Most USPS shipping labels usually include a tracking number with an Intelligent Mail package barcode (IMpb), and some also include a QR code. If you have the USPS app installed on your mobile phone you can simply scan the barcode using your phone’s camera.
It’s even easier if there’s a QR code. You can just use your smartphone camera to open the tracking page by pointing it at the code.
Method 1: Scan in the USPS Mobile App (Best)
Install the application and then go to the tracking section where you’ll see a little camera icon waiting for you. This is what you’ll click on and use to scan shipping label details.
With this feature, the tracking number digits are auto filled so that you don’t have to do it manually. It saves time and prevents those annoying typos that lead to error messages. Once the info pops up, the USPS app tracking system shows if your box is in transit or out for delivery. You can even tap a button to save the shipment for later updates.
Method 2: Use Your Phone Camera for USPS QR Links

If you noticed that the email or shipping label came with a QR code, then that’s good news. All you have to do is open your Camera app and then point it at the code until you see a notification pop up. Always confirm that the link is from an official carrier site, like USPS.com.
iPhone users can also use the Code Scanner in the Control Center if they prefer. Android users can do the same with built in QR scanning tools. Once you click on the right link, it will take you to where you can see all of the latest tracking updates.
Understand “Label Broker®” QR vs. Tracking
What the USPS Label Broker QR code does is to pull up a prepaid shipping label. This allows it to be printed either at a Post Office counter or a kiosk.
It is a real time saver when you either do not have a printer or you just want to avoid ink and paper at home. The label contains the tracking number, which you may also see on your receipt or the email confirmation you receive. After USPS gets the package and scans it, tracking updates will start to show all of the movements through the system.
Where/When USPS Scans Happen (So You Don’t Panic)
Tracking updates allows you to know the status of a package as it moves along the way from one facility to another.

Sometimes a label may be created in advance, but the journey will usually not show up in tracking until USPS already has the item and scans it into the network. This is a delay that usually happens with mail slot drop offs.
Once it has been scanned, you will be able to see acceptance related events along with in transit activity. After it reaches the local delivery unit, it then goes out with the carrier. The delivery scan confirms that the carrier has completed the delivery.
Troubleshooting Scan & Tracking Issues
Label scanning should usually be a fast process, but a few things can affect and trip it up. One of such things is glare from a shiny tape. This can hide the barcode lines. Also, the code might be too faint to read if there is low quality or smeared ink.
You can avoid all of these problems by placing the package under a good light source, shifting the angle to avoid reflections, and ensuring there are no folds on the barcode so that it lies flat. If it still won’t scan, you can use manual entry for the tracking number when that option is available.
International & Hand-Off Packages
During international shipping, what you need most of the time is the tracking number on your USPS receipt to check where your parcel is.
With USPS international tracking, there are different progress updates you can see. These include acceptance, export, arrival, and sometimes customs movement. By the time your package arrives in a new country, there’ll be a partner carrier handoff. This means that the local postal service will take over.
Safety & Authenticity (Quick Check)
Real QR codes are usually found in specific locations. These include printed labels and official shipping emails. You should always treat each of your QR scans like a website visit. Always try to double-check if the page actually belongs to USPS. This means that the domain should either be usps.com or a subdomain such as tools.usps.com.
Another thing to be mindful of is phishing texts. They try to mimic USPS branding so that it looks real to unsuspecting customers, and use tricks such as “issues with your shipping address” warning to push you into making bad decisions.

If you are ever in doubt, manually visit USPS tracking in your browser.
Conclusion
Managing your mail is much easier when a smartphone does the heavy lifting. The mobile app stands out as the most efficient choice to track USPS by phone while on the move. Most people find that using the camera to scan to track specific QR codes on shipping labels provides the quickest updates.
Just keep in mind that the Label Broker code is only meant for printing a label and does not provide status updates. The actual monitoring begins with the printed barcode number as soon as the package is scanned into the system. Once you have activated your USPS tracking alerts, you’ll be able to get notifications once the delivery reaches a new facility.
