Why did my eBay tracking number change during transit?

It’s common for an eBay tracking number to change while the package is in transit, especially for international or multi-carrier shipments. This usually happens for one of the following reasons:

1. The package was handed over to a different courier.
Many eBay sellers, especially international ones, use multiple logistics partners. When the parcel arrives in the destination country, it is often transferred to the local postal service (USPS, Royal Mail, Canada Post, etc.), which assigns a new tracking number.

2. The original tracking number was only valid in the origin country.
Services like China Post, YunExpress, 4PX, and SpeedPAK issue an initial tracking number for export. A new domestic tracking number is created once the shipment enters your country.

3. The Global Shipping Program (GSP) uses two tracking numbers.
If your order uses eBay’s GSP:

• One number covers shipping to the US/UK processing center.

• A second number covers the final delivery to you.

4. Carrier relabeling.
Some couriers re-label packages at sorting hubs to improve routing efficiency, which results in a new tracking ID.

5. Marketplace logistics partners generate multiple IDs.
Amazon-style third-party sellers on eBay often ship with consolidated logistics, where several internal tracking codes are used before the final one is created.
