You are at the final step, where you can verify the tracking number. Using the service indicator code, determine the type of parcel and find the courier that issued your tracking number. The data is sorted by the first two letters (Service Indicator Code). Look at your number and find the first two letters from the list. You can use the hotkeys Ctrl+F for Windows or Command+F on Mac or Mobile Chrome (select More (3 dots) > Find and edit > Find...) to speed up the search.

If you have found your Service Indicator Code, you will see the type of your parcel and a list of numbers divided by postal operators. For example, if the parcel is from China, the tracking number will end in "CN", and the postal operator is China Post. If you are waiting for a parcel from the USA, the number will end in the "US", indicating that the carrier is USPS.

Find your postal service from the list, where you will see valid tracking numbers. If your number is on this list, you can be sure that your number has been validated and complies with the UPU S10 standard.

If you haven’t found your tracking number, this is also possible. In this case, pay attention to any carrier's Serial Number and Check-Digit (9 digits in the center of the tracking number). If they correspond to your tracking number, it also indicates that the number is valid.

Now what? You have found out everything possible about your number. If you are convinced your number is correct, we advise you to track it on our parcel tracker. Pay attention to where the package is going. It is essential to know that the package is moving precisely towards you, and you can react if this is not the case.

If you make a mistake and select the wrong numbers in step 2, go back a step or back to the first step.
