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.
