How to Hide Your Phone Number When Messaging and Signing Up

Many services ask for your phone number, then use it to link accounts and send marketing.

Messaging

• Use messaging apps that support usernames instead of numbers.
• Limit who can see your number in privacy settings.

Sign-ups

• Give a number only when it is really required.
• Use a secondary number or a forwarding service for non-critical accounts.
• Prefer authenticator apps over SMS for security.

Reduce spam

Do not post your number publicly and opt out of data broker lists.
