5 Fixes: ‘This Number is Already Registered’ TikTok

Have you ever tried to sign up for TikTok and got told your phone number is already registered? This can be confusing, especially if it’s your first time using TikTok.

Here’s a simple guide to help you understand why this happens and what you can do about it.

Why does TikTok say ‘this number is already registered’?

TikTok says “phone number is already registered” usually because the number has been used for another account already. This can happen if you’ve forgotten about an old account, the number was previously used by someone else, or it’s a simple mistake in entering the number.

  • You might have used it before: Maybe you signed up a while back and forgot about it.
  • Someone else had your number: If you got a new phone number, someone else might have used it for TikTok before you.
  • Mistakes happen: Double-check the number you entered to make sure it’s correct.
  • TikTok’s safety rules: TikTok does this to stop people from making lots of accounts with the same number.
  • Technical glitch: In rare cases, a technical issue on TikTok’s end might cause this error message.

  • Go to ‘Me’ at the bottom right, then tap the three dots at the top right for ‘Settings and Privacy’.
  • Scroll down and tap ‘Report a Problem’.
  • Go to ‘Account and Profile’ > ‘Email and Phone Number’ > ‘Changing the phone number or email associated with your account’.

  • Type “I need to change my registered phone number as I don’t have access to it anymore” and send.
  • Follow the prompts to verify your identity.
  • Once verified, follow the instructions to update your phone number or finish the process.
