Why does my Aliexpress tracking number change?

It’s normal for an Aliexpress tracking number to change during shipment. This happens because your package may be handled by multiple logistics companies as it moves from China to your destination. Common reasons include:

1. The parcel was handed off to a new carrier.
Aliexpress shipments often start with a Chinese logistics provider (Cainiao, China Post, YunExpress, SunYou, 4PX).
When the parcel reaches your country, a local postal service (USPS, Royal Mail, Canada Post, La Poste, etc.) may assign a new domestic tracking number.

2. The original number was only valid inside China.
Export tracking numbers are often used only until the package leaves China.
Once it arrives at the destination country, a new tracking number replaces it.

3. Economy shipping methods use multiple internal numbers.
Cainiao Super Economy or consolidated shipping routes may generate several internal IDs before one becomes the final, trackable number.

4. Relabeling at sorting centers.
Large logistics hubs sometimes re-label parcels to optimize routing, resulting in a new code.

5. Combined shipments receive a new master tracking number.
If you ordered multiple items from the same seller, they may be packed together, and a new tracking number may be assigned.

In most cases, both tracking numbers refer to the same package—but only the newest number will show the final delivery updates.
