How to Block a Number on a GoPhone
AT&T allows users to block caller ID on a per-call basis through the menu on their handset. The instructions vary depending on what make and model of handset the user has. GoPhone is AT&T's prepaid wireless service. Users can also block caller ID permanently on all calls, or block their names and allow their numbers to go through.
Open your web browser and go to the AT&T Phone & Device Support page. You can find the link in the Resources section.
Ignore the first drop-down box, since it doesn't apply to GoPhones. Click the second drop-down box to select the manufacturer of the phone. Click the third drop-down box to select the model. Click "Next" to display the support menu for your phone.
Click the "+" next to "Calling Features" in the left-hand menu bar and click "Caller ID" to display detailed instructions for your GoPhone.
Follow the instructions to block your number.
Tips & Warnings
- AT&T also allows you to block caller ID on all calls, or to block only your name and not your number. These types of blocks require a feature on your account. Add the feature by calling AT&T at "611" from your GoPhone or (800) 331-0500 from another phone.
- If you don't know what your model number is, you can select the phone visually by clicking on "Find your device by image" on the Phone & Device Support screen.
