The demand for phone numbers will soon exceed those possible using seven digits. Ten-digit dialing permits more number combinations.
In areas where ten-digit dialing is required for all local calls, you need to dial the three-digit area code and the seven-digit phone number.
You won't be required to change your existing seven-digit telephone number, only add the three-digit area code.
The geographic boundaries that govern long distance haven't changed.
All three-digit numbers, including 211, 311, 411, 611, 811, 911 emergency service (where applicable) remain the same.
If your area has ten-digit dialing, ensure all of your communications equipment and systems reflect it:
Speed-dial lists
Modems and Internet connections
Telephones, including call options and functions such as Call Forwarding
Computers and fax machines
Databases
Auto-dial systems
Mobile devices
