To determine if your tracking number is fake or invalid, you can take the following steps:
Check the UPU S10 format. Ensure that the tracking number matches the UPU S10 format. You can visit the validation page and enter the tracking number to verify its validity, package type, and the postal service that issued the tracking number.
Track your package. Use the tracking number to track your parcel on the carrier's official website or through a trusted partner tracking service. If the tracking information is unavailable, not updated, or shows unusual or inconsistent data, it could indicate a fake tracking number.
Contact the carrier or postal service. Contact the courier or postal service directly and provide them with your tracking number. They can authenticate the tracking number and provide you with information on the status of your shipment.
Be cautious with surprising tracking numbers. If you receive a tracking number unexpectedly, especially from an unfamiliar source, exercise caution. It might be a phishing attempt or a scam. Please don't click on any links or share personal information associated with the tracking number.
