Your calling areas and rates will not be impacted by an area code split. Calls that were considered local before the introduction of the new area code will remain local calls. Calls that were considered long distance before the new area code will remain long distance calls. However, if your area code changes, you should notify family, friends and business associates of this change. You may also need to modify items such as stationery, business cards, advertisements, alarm equipment, automatic dialers, bill statements, checks, computer lists, electronic banking information, emergency contact lists, identification bracelets, fax machines, health provider cards, pet ID tags and speed dial lists.
Some business customers, particularly those with a PBX or ISDN service, may need to upgrade or adjust their own telephone equipment to handle the new area code. Not all business equipment will require upgrading. If you have specific questions regarding your equipment, please contact your vendor for additional information or assistance.
Once the new area code has been determined, a test number will be established at least 30 days prior to the start of permissive dialing. This will allow business customers to verify that their equipment can complete calls to the new area code. The test number may be obtained from the associated planning letter for each area code on NANPA’s website:
