I can't check it. If you don't write the mailing address and contact information, you can only find out where your courier comes from through the courier number.

If you really want to check, you can call the courier company, and their system can find the sender and the recipient.

The express delivery number is the unique identification code of the express package, which contains the detailed information of the recipient's express mail, usually consisting of numbers and letters. The courier number can facilitate the courier company, the sender and the recipient to track the courier information in real time.

In this case, if you don't want this courier, the solution is:

1. You can return the courier and explain the situation to the courier or customer service in JD.COM.

2. You can call the customer service phone of Jingdong Express. Express parcels will have a single number and voucher number to ask for relevant information, to see if there is any error in the internal information of JD.COM, and send the wrong items.
