To update your phone number, you first will need to make sure the mobile device you use Fetch Rewards on is verified. For more information on this, please see this article: Device Verification
Once your device is verified, your phone number can be updated inside the app by first tapping on the Me tab at the bottom of the screen, then selecting the small pencil icon next to your profile photo near the top of the screen.
You will then see three options at the bottom of the screen:
- Change photo
- Change password
- Change phone number
Select the Change phone number option, and enter the new number you would like to have associated with your account. You will need to verify the number you enter, and it must meet some requirements in order to be verified on your account.

Once you have verified the updated number, you are all set!
