1. Number already used to register an account

Another user may have already registered your phone number with TikTok. If you’ve just gotten a new phone and it turns out that someone else had used that number to sign up for TikTok, you can find that your phone number is linked to their account.

Additionally, if you just obtained a new phone number and want to sign up for TikTok with it, it’s likely that the company hasn’t had a chance to finish activating or registering your number. You should give it some time, maybe a few hours or days, and then try again.

2. Technical problem

Even though there is no other account linked with the phone number, TikTok may sometimes display the error message “phone number already taken” due to platform issues with technology. If this happens, try again later or get in touch with TikTok’s support team.

3. Previous phone left logged in with the same number

Your previous phone number might still be linked to the TikTok app if you just got a new one and forgot to log out before making the switch. We recommend that in this instance you sign out of your previous device’s account before attempting to sign up for a new one on your new device.

4. Fraudulent account

It’s likely that a fraudster is using your phone number to impersonate you on TikTok in an effort to defraud others. The best course of action in such a situation is to report the problem straight away to TikTok’s customer service.

Fix: TikTok says number already taken or registered

First, double-check that you entered the proper number before continuing with the rest of these troubleshooting steps.

The chances of your entered number being identical to one that has already been registered are slim, but they do exist.

Method 1: Remove your existing phone number.

If you have already created a TikTok account using your phone number and are attempting to establish a new account with the same number, it is likely that the old account is still active on your device.

In this scenario, you must remove the number before creating the new account and fixing the problem. The “How do I unregister my number from TikTok?” section explains in detail what has to be done in this regard.

Method 2: Register using a valid email ID

If you had trouble when you tried to join up for TikTok using your phone number, try signing up with an email address or username instead. When you select the option to Sign up for TikTok, you will get the option to ‘Use phone or email’. Select this to continue with the signup process using your email address.

Any documentation proving your phone number is acceptable. Within a few business days, you should hear back from someone on the TikTok support staff after contacting them.

1. Why doesn’t TikTok recognize my phone number?

The fact that TikTok won’t let you sign up with your phone number indicates that it’s been used for another account. You may have an old account associated with your phone number that you are unaware of.

Therefore, you must delete the old account before you may use the same phone number to register for a new one.
