How to change or remove your phone number on X
In short
- In Settings and privacy, open your account information, then Phone, enter your password, and choose Update number or Delete number.
- An X account can have only one phone number.
- Lost the phone? X says a backup code lets you log in.
X uses your phone number for sign-in checks, two-factor codes and, if you allow it, for people to find you.
Change or delete it
In Settings and privacy, open your account information, then Phone. X asks for your password, then offers Update number or Delete number. For a new number, enter the code X texts to it. X also suggests revoking access for apps connected through your old phone.
One number per account
An X account can have only one phone number, even on a dual SIM phone.
Two-factor authentication
If text codes are your only second step, set up an authentication app first, so deleting the number doesn’t lock you out. Save a backup code: X says it lets you log in if you lose your phone or change your number.
Who can find you
People can find your account by your phone number unless you turn off phone discoverability in your privacy settings.
After a one-time number
A number from ReserveSMS receives codes for 20 minutes only, so add an email and use an authentication app for two-factor. See X phone verification.
