Why should WeChat add friend verification information?

First, you deleted the other person, but the other person didn't find you and didn't delete you from the address book, so you won't be prompted to verify the message if you add him as a friend again. When you add him, there is no "Need to send verification application" interface.

Second, if you delete the other person, the other person will delete you, so if you add him as a friend, he will have a verification message. When adding him, the "Need to send verification application" interface appears.

Third, if you accidentally delete your friends by mistake, you can add them back like this:

1. If there is a record of adding friends in the new friends, check whether there is a friend application for deleting friends. If there is, you can accept adding friends again.

2. In the Add Friend interface, if you remember your friend's micro signal, QQ number or mobile phone number, you can try to add it.

3. If there is a group chat to join, find the deleted friend's avatar in the group friends, and click to try to add it again.

4. Check the circle of friends. If there is a reply message from a deleted friend in the circle of friends, click the underlined name and try to add the friend again.

5. If the phone number of a friend is saved in the mobile phone address book, you can try to add a mobile phone contact to add a friend again.
