Mobile number required to register a new Yahoo ID

One of the ways Yahoo helps to protect accounts is by requiring a mobile number to sign up. If you don't provide a supported mobile number, you'll be unable to complete registration.


Why is a mobile number required?

Adding a mobile number to your account is an important account security step. Here's why: 

  • Greatly reduces the risk of an abuser accessing your account.
  • If you need to recover your password, this is the safest and most effective method to recover it.
  • Yahoo will alert you through your mobile device when we suspect unusual login activity on your Yahoo account.

  Did you know? Yahoo does not rent, sell, or share your personal information with other people or non affiliated companies, except to offer products or services you've requested. See our Privacy Policy for more detailed info on how we keep your information private.
