Once in a while, we need to introduce new area codes so we can make more phone numbers available. This is called an area code overlay.
When this happens, you may have to dial your own area code to make a local call.
To ensure a continuing supply of telephone numbers, the Alabama Public Service Commission has approved the addition of the new 483 area code to the geographic area served by the 334 area code. This process is known as an area code overlay.
What is an area code overlay?
An area code overlay is the addition of another area code (483) to the same geographic region served by an existing area code (334). An overlay does not require customers to change their existing area code but does require customers to use a new dialing procedure to complete telephone calls.
Who will be affected?
The 334 area code serves Montgomery, Alabama and other cities such as Dothan, Auburn, Prattville, Phenix City, Enterprise, Opelika, Selma and many other smaller communities. Anyone with a 334 or 483 area code will need to use a new dialing procedure.
What will be the new dialing procedure?
To complete calls from a landline phone, anyone with a 334 or 483 area code must dial area code + telephone number. This means that all calls in the 334 area code that are currently dialed with 7 digits will need to be dialed with 10 digits using the new area code + telephone number dialing procedure.
To complete calls from a cellular or mobile phone, callers may dial area code + telephone number or 1 + area code + telephone number whenever placing a call from a phone number with the 334 or 483 area code.
When will the change begin?
Beginning July 23, 2025, you should begin using the new dialing procedure whenever you place a call from the 334 area code. If you forget and dial just 7 digits, your call will still be completed.
Beginning January 23, 2026, you must use the new dialing procedure, as described above for all calls, even for local calls. On and after this date, if you do not dial area code + telephone number, your calls will not be completed, and a recording will instruct you to hang up and dial again.
Beginning February 23, 2026, new telephone lines or services in the 334 area may be assigned numbers from the new 483 area code. Anyone assigned the 483 area code telephone number must use the new dialing procedure described above.
What will you need to do?
In addition to changing the way you make local calls, all services, automatic dialing equipment, or other types of equipment that are programmed to dial 7 digits will need to be reprogrammed to dial area code + telephone number. Some examples are life safety systems and medical monitoring devices, PBXs, fax machines, Internet dial-up numbers, fire or burglar alarm and security systems or gates, cordless and mobile phone contact lists, speed dialers, call forwarding settings, voicemail services, and other similar services or equipment. You may also want to check your personal and business stationery, checks, advertising materials, websites, contact information, and personal or pet ID tags to ensure the area code is included in the telephone number.
What will remain the same?

The California Public Utilities Commission (CPUC) will begin the process to introduce a new area code to the area now served by the 626 area code, as the 626 area code is expected to be depleted of phone numbers in the fourth quarter of 2027. Pending approval by the CPUC, the new area code will be introduced on top of the 626 area code using the overlay method.
The CPUC will have a recorded webcast to inform the public about the overlay. Topics to be discussed in the recorded webcast include: (1) History of the 626 area code; (2) Area code relief process; (3) Overlay relief method; (4) Effects of the pending overlay; and (5) Implementation periods. The recorded webcast will be available at https://www.cpuc.ca.gov/AreaCodes/ beginning May 13, 2025. Comments about the 626 area code overlay may be submitted to the CPUC Public Advisor’s Office by e-mail at public.advisor@cpuc.ca.gov, or by postal mail to 320 W. 4th Street, Suite 500, Los Angeles, CA 90013 by June 13, 2025. A copy of the webcast presentation slides may be requested by contacting the CPUC Public Advisor’s Office by email at public.advisor@cpuc.ca.gov, or by phone at (866) 849-8390.
