Important Notes:

Tracking information usually becomes available 2–7 days later; tracking records will not be displayed immediately after the seller ships the package.

 

If the tracking number is purely numeric (e.g., 1234567890123), it is generally a domestic tracking number; an international tracking number will only be generated after the package leaves China.

 

Some low-cost logistics (such as China Post regular small packets) may have no tracking information or only track up to customs clearance.
