When signing, you need to show your ID card, tell the courier the mobile phone number, and sign for it at the signer.

Precautions for signing for express delivery:

1. After you get the goods, you can ask for inspection before signing for them. (Most couriers may disagree, because they are afraid that they will not sign for the goods after opening them, so the couriers will take full responsibility for the goods and cannot explain them. )

2. If you can't do the above, you can sign for it normally first, and then take the list in your hand (very important) for the time being, and then ask for inspection. At this time, because it has been signed, the courier has no reason not to inspect the goods.

3. If there is no problem in the inspection, you can give the list to the courier and the transaction is successful.
