What should I do if I write the wrong mobile phone number online?

You can use Alibaba Want Want to contact the seller and ask him to change your notes for you. The seller will communicate with the logistics company to change the specific operation, so you don't have to worry.

If the goods have arrived in the local area, you can take the mobile phone number, waybill number and other information displayed in the "order details" to pick up the goods at the logistics outlets, or use it as a proof for the employees of the logistics company to deliver the goods to the door.

In short, it is these three situations:

The seller didn't deliver the goods. You can contact him directly and change your mobile phone number.

The seller has delivered the goods, you contact him, and the seller contacts the logistics/express merchant to change the contact information of the remarks;

The goods have arrived in the local area and will be sent to me soon (if the mobile phone number is invalid or wrong, the express delivery should not be smooth). Go to the express outlet to pick it up yourself, and carry the relevant documents as follows:

My mobile phone number, ID card, and my mobile phone. If there is a mobile phone Taobao on the mobile phone, then the details of your baby's order displayed after landing can be used as the basis for picking up the goods. If you confirm that you are me, the express delivery can be relieved.

So the wrong number is not a big deal.
