Block a Number on ATT

Mobile phone users may try to keep their phone number private. If you find yourself receiving calls from telephone solicitors or unwanted people on your AT&T phone, you can sign up for a service to block them and/or join the "Do Not Call" registry. Find out how to block a number on AT&T.

Steps

Research the Number

  1. Write down the number that you would like to block. Make sure you have all 10 digits available before you arrange to block it.
    • AT&T does not have the capability to block anonymous numbers from your phone. If the number you dislike is from "Private Number" or "Anonymous" you should ask the person or telemarketer to remove you from their phone or list and never call you in the future.
    • It is a good idea to enroll your number in the US "Do Not Call" registry no matter what wireless service you use. It will be the cheapest option to block numbers, if you are receiving unwanted calls from solicitors.

If you have an iPhone with iOS7

  1. If you have an iPhone, with iOS7 or newer, you can block the number from the iPhone.
  2. For older iPhones and other phones, proceed to the following paragraphs.

Join the Do Not Call Registry

  1. Call the US Do Not Call registry service using the number that you would like to block from telemarketers. The number is (888) 382-1222.
  2. Follow the prompts to register for the service. The registry will pick up your cellular phone number automatically, but you may be asked to answer some questions regarding your number.
  3. Wait 31 days for the number to be added to the registry.
  4. Ask telemarketers to remove your name and number from their list immediately. This may take care of the problem.
  5. Ask them their business name and number, if you still receive calls. They are now in violation of the Do Not Call Act.
  6. Register a complaint with the Do Not Call service at donotcall.gov/complaint/complaintcheck.aspx. Telemarketers in violation of the Act can be fined.
