4. Aliexpress-specific formats
Some cheap or economy shipments use internal codes that become trackable only after export.

In short:
Aliexpress tracking numbers may contain letters + numbers, vary in length, and often end with a country code (CN, SG, HK). Different formats reflect different carriers and logistics routes.
