How to check the express number of my mail by mobile phone number?

I didn't find it possible except postal EMS.

The courier number contains the detailed information of your express mail, usually consisting of numbers and letters, and is the unique identification code of your express parcel. The courier number is convenient for the courier company, the sender and the recipient to track the courier information in real time.

Postal EMS mobile phone number query method:

1. To query EMS express by mobile phone number, you must install WeChat on your mobile phone, open the WeChat interface, click the+sign in the upper right corner, and select "Add Friend" in the pop-up menu.

In the search results, "EMS China Post Express Logistics" will be displayed, and this item will generally appear at the front. Click Open.

2. Click "Service" below, and then click "I want to inquire". The effect is the same as the previous step.

3. Enter the mobile phone number, of course, which is reserved for this courier, and then click "Get Verification Code" to fill the received SMS verification code into the "Verification Code Box", and then click "Query".
