Area code updates and dialing procedures

Communications technology in the U.S. has exploded in recent years. In addition to growth in home and business telephones, the industry has seen an increase in wireless and other communication devices of all kinds. Because of this growth, we’re running out of telephone numbers.

In some areas, the need for new numbers is so great that new area codes are being added. For information on recent area code activities and how they may affect you, choose from the states/area codes listed below.

The addition of new area codes will not affect the price of telephone calls placed over AT&T networks.

Note: Dialing 911 and calls to directory assistance are not affected by the updates. If 211, 311, 411, 511, 611, 711, or 811 are available in your community, you can still dial three digits.
