Questions and Answers

Suppose you have a tracking number for an international package and are still determining the sender's credibility or the online store from which you made the purchase. Our service can help validate the tracking number according to the UPU S10 standard. To do this, enter the tracking number in the provided input field, and we will provide you with comprehensive information about the type of parcel and the postal operator that issued the tracking number.

A tracking number is a unique alphanumeric code assigned to a parcel, shipment, or letter that allows you to identify and control its movement throughout delivery. It serves as an identifier to track the activity and status of the movement of goods from origin to destination. Tracking numbers are typically provided by postal services, courier companies, or logistics providers and can be used by senders, recipients, and carriers to track a shipment's progress and receive real-time updates on its location and delivery status.

Not all shipments are tracked, primarily due to the lower cost associated with their delivery. According to the UPU S10 standard, only tracking numbers starting from the LA-LZ range are available. However, there may be cases where other parcels can be tracked in the recipient's country, but this is optional and may vary depending on the specific postal service or carrier.

According to the UPU S10 standard, it is impossible to determine the country of destination based solely on the tracking number. However, you can identify the postal operator that issued the tracking number and select the type of mailing. If you want more information, you can visit the carrier's official website and track your package using the provided tracking number. The carrier's website will give you the most accurate and up-to-date information on the status and location of your package.

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.
