Lost the phone number on your AWS account? You can usually still get in with your email, a backup code or a device where you are signed in. Here is the order to try, and how to stop it happening again.
Developer and cloud platforms check phone numbers to keep out abuse of free resources and to protect accounts that can run up bills. AWS sign-up asks you to confirm a phone number by text message or voice call. When you sign in on a new device or reset the password, AWS sends the code to the number on file, not to the phone you are holding.
| You still have | Do this | How fast |
|---|---|---|
| AWS open on another phone, tablet or computer | Change the phone number in settings there | Minutes |
| Access to the account email | Use the email code or reset link | Minutes |
| Backup codes or an authenticator app | Sign in with a code, then update the number | Minutes |
| Only your password | Use AWS's recovery form or support | Hours to days |
| Nothing | Recovery form with proof of ownership (old passwords, payments, ID) | Days, not guaranteed |
If the root user's MFA device is gone, use the troubleshooting link on the sign-in page; AWS checks the account email and phone, and AWS Support can help. MFA for the root user and IAM users can use an authenticator app, a security key or a passkey (Security credentials). AWS recommends MFA on the root user and using IAM or Identity Center users for daily work.
Add the new number in AWS while the old one still works, and remove the old one afterwards. Carriers give unused numbers to new customers after a while, so an old number left on the account can end up with a stranger.
Usually yes: through a signed-in device, your email, backup codes or AWS's recovery form.
Use AWS's recovery form or support, and expect to prove the account is yours. It takes longer, so answer carefully and send one request.
Email and backup-code recovery is instant; recovery forms can take hours to several days.
No. AWS sends codes to the number already on the account. Add the new number after you are back in.
Sometimes, if you contact the carrier soon after losing it; after a few months it may be given to someone else.
Support follows the same checks as the recovery form, so have proof of ownership ready, such as the account email, old passwords or payment details.
