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.
