How to Change the Phone Number on Your Yahoo Account

Change your Yahoo phone number in Account Info › Account security. Add the new number, confirm the code, then remove the old one.

Steps on the web

1. Sign in to Yahoo and open Account Info from your profile name.
2. Go to Account security or the recovery settings section.
3. Choose to add a phone number and enter the new one.
4. Type the code Yahoo texts you.
5. Remove the old number.

In the Yahoo Mail app

1. Tap your profile picture and open Manage accounts.
2. Tap Account info › Security settings.
3. Edit the phone numbers listed there.

Why the number matters

Lost the old number already

If you can still sign in, add the new number straight away. If Yahoo asks for a code to the old number, choose another way, such as your recovery email. If none works, use Yahoo's Sign-in Helper; see Yahoo recovery.

Better than text codes

Yahoo supports an authenticator app and Account Key sign-in through the Yahoo app. Turning one on means a future number change will not block you. See Yahoo two-step verification.

Check after changing

• Sign out and sign back in once to see where the code goes.
• Check that mail apps on other devices still work.
• Make sure the recovery email is also up to date.

Number already used

Yahoo may limit how many accounts one phone number can be added to. If it refuses the number, remove it from an older Yahoo account you no longer use, or use another number you own.

AOL accounts

AOL accounts belong to the same company and use a very similar security page. The same steps apply there.

Keep the old number for a while

If you can, keep the old SIM working for a week after the change, in case a service still sends a code there.
