Some China Post agents also provide some kind of mock “tracking number” for China Post Regular Airmail in order to fulfill the marketplace requirement.

Such kinds of mock “tracking numbers” have different forms, i.e CP1233456789, YW123456789YW,YC123456789YW, 123456789BJ,RI123456789EN,WD123456789CN …. Sometimes, those tracking number can shows some parcel pickup info and airport info in the agent’s own website. In most cases, the parcels from big agent such as Yanwen will arrive destination without any problem. However, these tracking number have nothing to do with China Post and China Post can not verify the authentic of the parcel shipment.

If you got such number over 30 days and can not receive the goods, you should open dispute to your seller.
