Go to Roblox Settings and open Account Info. Then click Add Phone , enter your country/area code and phone number, and Roblox will send you a 6-digit code by SMS or sometimes WhatsApp; enter that code to finish verification. Roblox also notes that this feature is only available in some countries, so the Phone Number option may not appear for everyone.

Quick steps

  1. Sign in to Roblox.
  2. Open Settings.
  3. Select Account Info.
  4. Click Add Phone.
  5. Enter your phone number.
  6. Enter the code Roblox sends you.
  7. Confirm and finish setup.

If it does not work

  • Make sure the number is a personal mobile number and typed correctly.
  • Check that your country supports phone verification, because Roblox says the feature is available only in select countries.
  • If you do not receive the code, check SMS/WhatsApp messages and try again later.

Why verify it

Verifying your phone helps with account recovery and adds an extra layer of security to your Roblox account.
