17TRACK currently has not connected with Aliexpress shipping or cainiao tracking system yet. Hence, our system cannot recognize Aliexpress or Cainiao shipping numbers.
17TRACK can only track original tracking numbers from the actual carrier. The reference numbers from any platforms cannot be regarded as tracking numbers as the local carriers could not recognize these numbers when the parcels arrive in the destination countries.
The Aliexpress merchants(shipper) would know the shipping method and the real carrier so you can get the original tracking number from them, then you can directly track it on 17TRACK; for example: for the tracking number, LP0000000008 you can designate the carrier to YANWEN.
