I forgot my previous QQ number. How can I get it back? I can't remember the registration password or anything.

After successfully applying for QQ number, it is recommended that you manually copy and save the QQ number locally. If there is no record and the page is closed, the QQ number cannot be retrieved on the webpage. If you forget your QQ number, you can try to get it back in the following ways:

1. If you add friends, you can ask them to check your QQ number directly in their friends column;

2. If you remember the QQ nickname, you can try to log in to another QQ number and use the "query" function to find it;

3. If you register with your mobile phone account, the QQ number will be automatically bound to your mobile phone. Please log in to QQ directly with the mobile phone number that you received the verification code at that time.

4. Check the computer with QQ number to see if there is a folder with your QQ number under the QQ installation directory;

5. If you have set up a QQ email as an auxiliary account, I suggest that you can log in to my QQ center, enter your email account and QQ password, and you can log in normally. After logging in successfully, your QQ number will be displayed on this page.

If you apply for a free number on the web page, you can't get it back through the above methods. I suggest you apply for a new QQ number.
