Cómo cambiar numero de teléfono celular para recibir un código?

Answer 1

Dear Sergio,

Thanks for posting in the Microsoft Q &A

From your message, it seems you’re trying to change the phone number linked to your Microsoft account in order to receive verification codes—perhaps for signing in, using Microsoft Authenticator, or activating a Microsoft product.

To help you better, could you please confirm the following:

1. Are you trying to change the number for a personal Microsoft account (e.g., @outlook.com, @hotmail.com), or a work/school account?
2. Are you able to sign in to your Microsoft account currently, or are you locked out?
3. Are you using two-step verification (MFA) or Authenticator app?
4. What product or service is prompting you to receive a verification code?

In the meantime, here are general steps to update your phone number:

If You Can Sign in to Your Microsoft Account

1. Go to https://account.microsoft.com
2. Sign in, then select “Your info”
3. Under Account info, click “Manage how you sign in to Microsoft”
4. Select “Add a new way to sign in or verify”
5. Choose Phone number, enter your new number, and follow the verification steps
6. Once verified, remove the old number if no longer needed.

If You Can’t Sign In (Lost Access to Old Number)

1. Go to https://account.live.com/acsr
2. Follow the account recovery process
3. You may be asked to verify using:
   • Recovery email
   • Microsoft Authenticator
   • Past account details (e.g., subjects of recent emails, Xbox settings)

Note: Recovery may take a few days. Be as accurate and detailed as possible.

Let us know the answers to the above questions so we can tailor the steps more precisely for your situation.

Best wishes,
