Communications technology in the U.S. has exploded in recent years. In addition to growth in telephones numbers, 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.

Calling toll free and 900 numbers
Toll-free numbers begin with one of the following three-digit area codes. Charges to these toll-free numbers are almost always paid by the party being called.
The charge for calling 900 numbers varies and is set by the service provider offering the product or service. Be aware of the cost to dial the 900 number before you call.
