Thanks a lot , I tried as above. Twitter says it's not in the database.(I checked my phone  number and it's correct)

But I still can not associate my phone with my account.

On your computer, open a browser, go to this page.

[https://twitter.com/account/begin\_password\_reset](https://twitter.com/account/begin_password_reset)

Type your phone number.

If your phone is in their database, you will receive a text message with instructions to reset your password. If it is not, they will tell you it is not the database.

When I try to associate account A with my phone number ,twitter says that:

**The phone number you're trying to use is already associated with another Twitter account.**

But when I try forget password and enter my phone number , twitter says:

**We couldn't find your account with that information**

So what should I do now???

My phone number is registered but I can't find my account with my phone number
