Area Code Splits & Overlays

What is an area code split?

The exhausting area code is split into two or three geographic areas, leaving the existing area code to serve one side of the geographic area and assigning one or two new area codes to the other segment(s).

What is an area code overlay?

An area code overlay occurs when more than one area code serves the same geographic area. In an area code overlay, relief is provided by opening up a new area code within the same geographic area as the area code requiring relief. With an overlay, all current customers keep their area code and telephone number. Numbers from this new area code may be assigned to new telephone customers or those adding additional lines. Because two area codes reside in the same geography, all calls must be dialed using the area code + the seven-digit telephone number (10 digits). (Some states require 1+10-digit dialing)

What is 10-digit dialing?

10-digit dialing is a term used to refer to the practice of including the area code of a phone number when making local calls. It is the required dialing pattern in locations throughout the country that have undergone an area code Overlay. For example, if area code (123) is overlaid with area code (456), then callers within the area served by 123/456 must dial 10-digits in order to place a local call even if the call is from a (123) number to another (123) number. Pre-subscribed long distance calls still require 1+10-digit dialing. Consumers in areas subject to an Overlay should replace all 7-digit telephone numbers programmed into their wireless phones and other devices with 10-digit telephone numbers.

What is Permissive Dialing?

The permissive dialing* period begins with the introduction of the new area code and generally lasts approximately six months. It provides a 'get acquainted' transition period for the new area code. Permissive dialing allows the old and new area code customers to call between the two area codes using seven-digit dialing. During this period, customers should begin to use the area code + the telephone number although calls will still complete if only the seven-digit telephone number is dialed. Customers, from outside the area, can call the new area code by dialing either the old or the new area code + the telephone number; the call will complete during the permissive period. (* The permissive dialing period varies in length per commission decision)

What is Mandatory Dialing?

Approximately six months after the introduction of the new area code, an intercept recording period will begin. At this time, callers must use the appropriate area code plus the telephone number. Calls incorrectly dialed will be referred to a recording throughout the recording period. It will inform the calling party that the new area code must be used to complete the call.

If you have family or friends deployed in the military outside of the United States, make sure they know and use your new area codes.

 

 

NOTICE NEW AREA CODE TO BE ADDED TO THE 657/714 AREA CODE

The California Public Utilities Commission (CPUC) will begin the process to introduce a new area code to the area now served by the 657/714 area code, as the 657/714 area code is expected to be depleted of phone numbers by March 2027. Pending approval by the CPUC, the new area code will be introduced on top of the 657/714 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 657/714 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 July 19, 2024.

Comments about the 657/714 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 August 19, 2024.

Area Code Overlay Approved for the South Carolina 864 Area Code

To ensure new telephone numbers are available, the Minnesota Public Utilities Commission approved the addition of the new 924 area code to the geographic region of the 507 area code. This process is known as an area code overlay.

 

What is an area code overlay?

An overlay is the addition of another area code (924) to the same geographic region as an existing area code (507). An overlay does not require customers to change their existing area code but does require using a new dialing procedure to complete calls.

 

Who will be affected?

The 507 area code covers southern Minnesota and cities including, but not limited to Albert Lea, Austin, Fairmont, Mankato, Northfield, Rochester, Winona, Worthington, and other smaller communities. Anyone with a 507 area code will need to use a new dialing procedure, but will not have to change their telephone number. New telephone numbers may be assigned in the new 924 area code.

 

What will be the new dialing procedure?

All calls in the 507 area code geographic area that are currently dialed with seven digits will need to be dialed using area code + telephone number. The same dialing procedure will apply to both 507 telephone numbers and telephone numbers that are assigned in the new 924 area code.

 

When will the change begin?

Beginning July 30, 2024, you must dial the area code + telephone number on all calls, including calls within your same area code. If you do not dial the area code + telephone number, your call will not be completed, and a recording will instruct you to hang up and dial again, including the area code.

 

Beginning August 30, 2024, new telephone lines or services may be assigned numbers with the new 924 area code.

 

What will change?

  • Dial the area code + telephone number for local calls.
  • All services, automatic dialing equipment, or other types of equipment that are programmed to dial a 7-digit number will need to be reprogrammed to include the area code. Some examples are: life safety systems and medical monitoring devices, fire or burglar alarm and security systems or gates, fax machines, Internet dial-up numbers, speed dialers, call forwarding settings, voicemail services and similar functions, etc.
  • Update your websites, personal and business stationery and checks, advertising materials, personal and pet ID tags and other such items to ensure the area code is included.

 

What will remain the same?

  • Your telephone number, including current area code.
  • The price of a call, coverage area, or other rates and services will not change due to the overlay.
  • What is a local call now will remain a local call regardless of the number of digits dialed.
  • You can still dial just three digits to reach 911 and 988, as well as 211, 311, 411, 511, 611, 711 or 811 if available in your area.

What is an area Code Overlay?

An overlay is the addition of another area code (821) to the same geographic region as an existing area code (864). An overlay does not require customers to change their existing area code but does require using a new dialing procedure to complete calls.

The new dialing procedure will require that all calls in the 864 area code that are currently dialed with seven digits will need to be dialed using area code + telephone number. The same dialing procedure will apply to telephone numbers that are assigned in the new 821 area code.

 

When will the change begin?

Effective January 19, 2024, you should begin dialing the area code + telephone number whenever you place a call. If you forget and dial just seven digits, your call will still be completed. 

Beginning July 19, 2024, you must dial the area code + telephone number on all calls, including calls within the same area code. On and after this date, if you do not dial the area code + telephone number, your calls will not complete and a recording will instruct you to hang up and dial again, including the area code. 

Beginning August 19, 2024, new telephone lines or services may be assigned numbers with the new 821 area code. If you have a number in the new 821 area code, you must dial the area code + telephone number or the call will not complete.

 

What will you need to do?

In addition to dialing the area code + telephone number for local calls, all services, automatic dialing equipment, or other types of equipment that are programmed to dial a 7-digit number will need to be reprogrammed to include the area code. Some examples are life safety systems and medical monitoring devices, fire or burglar alarm and security systems or gates, PBXs, fax machines, Internet dial-up numbers, speed dialers, call forwarding settings, voicemail services and similar functions, etc. You should update your websites, personal and business stationery and checks, advertising materials, personal and pet ID tags and other such items to ensure the area code is included.

Dialing Plan Change Coming to 602 & 623 Area Codes in Arizona All Customers Required to Dial 10 Digits Starting August 12, 2023

To ensure a continuing supply of telephone numbers in the Phoenix metropolitan area, the Arizona Corporation Commission has approved the elimination of the area code boundaries between the 480, 602 and 623 in the Phoenix metro area. This boundary elimination overlay does not require customers with a 480, 602 or 623 area codes to change their existing area code or phone number but does require them to include the area code and the seven-digit telephone number on every call, including calls within the same area code.

 

Who will be affected?

The 602 area code principally serves the City of Phoenix. The 480 area code primarily serves the eastern region including Scottsdale, Chandler and Tempe. The 623 area code is currently assigned to the western and northern most areas including Buckeye, Glendale and Peoria. Everyone within these area codes will be affected by this boundary elimination overlay. With the implementation of the boundary elimination overlay, the Phoenix metropolitan area will be streamlined into a single, unified region, with no separate geographic areas in service, eliminating the need to change your landline number if you move between area codes.

 

When do I need to start dialing 10-digits?

Beginning August 12, 2023, 10-digit dialing will become mandatory throughout the 480, 602 and 623 area code regions, and calls that do not include the area code will not complete. If you forget and only dial 7 digits, you will hear a recorded message that advises you to include the area code. You will need to hang up and re-dial your call including the area code.

Beginning September 12, 2023, new telephone lines or services in the former ‘geographic’ areas served separately may now be assigned numbers from the area codes in 480, 602 or 623. All area code numbers may be ported throughout the Phoenix metro area since the boundaries between the area codes have been eliminated. As an example, if you or your business moves from Scottsdale to Phoenix, you will no longer be required to change your landline telephone number when moving into a different area code within the Phoenix metro area.

 

What will you need to do?

In addition to dialing 10-digits for all local calls, you should identify your telephone number as a 10-digit number (area code + 7-digit telephone number), and include the area code when giving the number to friends, family, business associates, and customers, etc. Please ensure all services, such as automatic dialing equipment, or other types of equipment that are programmed to dial a 7-digit number are updated to include the area code. Some examples are life safety systems and medical monitoring devices, PBXs, fax machines, Internet dial-up numbers, alarm and security systems, gates, speed dialers, mobile and cordless phone contact lists, call forwarding settings, voicemail services, and similar functions. Be sure to check your personal and business stationery, checks, advertising materials, websites, and your personal or pet ID tags to ensure the area code is included in your telephone number.

 

What will remain the same?

  • Your telephone number, including the current area code, will not change.
  • What is currently a local call will remain a local call regardless of the number of digits dialed. 
  • The price of a call or other rates and services will not change.
  • You will continue to dial 1+ area code + telephone number for all long-distance calls.

An overlay is the addition of another area code (227) to the same geographic region as an existing area code region (240/301). The overlay does not require you to change your existing area code or phone number, or how you dial your calls. You will continue to dial the area code and phone number for all local calls, as you do today, within and between the 240, 301, and new 227 area codes.

 

Who will be affected and when does the new 730 area code become effective?

Beginning June 14, 2023, customers in the 240/301 area code overlay region may be assigned a number in the new 227 area code when they request new service or an additional line. Customers receiving a 227 area code will be required to dial the area code and phone number for all local calls, just as customers with telephone numbers from the 240 and 301 area codes do today.

 

What will you need to do?

Customers in the overlay region should:

  • Continue to dial 10 digits for all local calls, including calls within the same area code.
  • Continue to identify your telephone number as a 10-digit number, and include the area code when giving the number to friends, family, business associates, customers, etc.
  • Ensure that all services, automatic dialing equipment, or other types of equipment recognize the new 227 area code as a valid area code and continue to store or program telephone numbers as 10-digit numbers. Some examples are: stored telephone numbers in contact lists in wireless phones, PBXs, fax machines, Internet dial-up numbers, speed dialers, call forwarding settings, voicemail services, medical alert devices, safety alarm security systems and gates, or other similar equipment.
  • Check items such as your website, personal and business stationery and printed checks, advertising materials, contact information, and your personal or pet ID tags to ensure the area code is included.

 

What will remain the same?

  • Your telephone number, including current area code, will not change.
  • The price of a call, coverage area, or other rates and services will not change due to the overlay.
  • What is a local call now will remain a local call.
  • You will continue to dial 10 digits for local calls within and between the overlay area codes, and 1+10 digits for long distance calls.
  • You can still dial just three digits to reach 911 and 988, as well as 211, 311, 411, 511, 611, 711 or 811 if those are currently available in your community.

NOTICE NEW AREA CODE TO BE ADDED TO THE 559 AREA CODE

Dialing Plan Change Coming to 602 & 623 Area Codes in Arizona All Customers Should Dial 10 Digits Starting February 11, 2023

To ensure a continuing supply of telephone numbers in the Phoenix metropolitan area, the Arizona Corporation Commission has approved the elimination of area code boundaries between the 480, 602 and 623 area codes in the Phoenix metro area.

 

What is boundary elimination overlay?

A boundary elimination overlay for the Phoenix metro area means the three area codes serving the Phoenix metro area will all serve the same geographic area, there will no longer be a boundary between the 480, 602 and 623 area codes and the three area codes will all serve the same combined geographic region. A boundary elimination overlay does not require you to change your existing area code or phone number but will require you to include the area code when dialing all calls, including local calls.

 

Who will be affected?

The boundary elimination overlay between 480, 602 and 623 area codes will affect callers in the Phoenix metro area which includes but is not limited to the communities of Avondale, Chandler, Gilbert, Glendale, Mesa, Phoenix, Scottsdale, Sun City, Sun Lakes, Tempe, and Tolleson.

 

When will the change begin?

Beginning February 11, 2023, anyone with a 602 or 623 area code should begin using 10 digits (area code + phone number) when dialing all local calls (Mandatory 10-digit dialing has already been implemented in the 480 area code). This includes all local calls which currently allow 7-digit dialing. During the permissive 10-digit dialing period, if you forget and only dial 7 digits, your calls will still complete. The permissive 10-digit dialing period will remain in place until August 12, 2023.

Beginning August 12, 2023, 10-digit dialing will become mandatory for anyone with a 602 and 623 area code, and their calls that do not include the area code will not complete. If you forget and only dial 7 digits, you will hear a recorded message that advises you to include the area code, and you will need to hang up and re-dial your call including the area code.

 

What will you need to do?

In addition to dialing 10-digits for all local calls, you should identify your telephone number as a 10-digit number (area code + 7-digit telephone number), and include the area code when giving the number to friends, family, business associates, and customers, etc. Please ensure all services, such as automatic dialing equipment, or other types of equipment that are programmed to dial a 7-digit number are updated to include the area code. Some examples are life safety systems and medical monitoring devices, PBXs, fax machines, Internet dial-up numbers, alarm and security systems, gates, speed dialers, mobile and cordless phone contact lists, call forwarding settings, voicemail services, and similar functions. Be sure to check your personal and business stationery, checks, advertising materials, websites, and your personal or pet ID tags to ensure the area code is included in your telephone number.

 

What will remain the same?

  • Your telephone number, including the current area code, will not change.
  • What is currently a local call will remain a local call regardless of the number of digits dialed.
  • The price of a call or other rates and services will not change.
  • You will continue to dial 1+ area code + telephone number for all long-distance calls.
  • You can still dial just three digits to reach 911 and 988, as well as 211, 311, 411, 511, 611, 711, or 811, if currently available in your community.

The New 363 Area Code is Coming to the New York 516 Area Code Region

To ensure a continuing supply of new telephone numbers, the New York Public Service Commission has approved an all-services area code overlay for the 516 area code region. The 516 area code comprises the entirety of Nassau County on the western portion of Long Island including the cities of Long Beach and Glen Cove, the Towns of Hempstead, North Hempstead, and Oyster Bay, and various villages within the Towns. The new 363 area code will serve the same geographic area currently served by the existing 516 area code.

 

What is an Area Code Overlay?

An overlay is the addition of another area code (363) to the same geographic region as an existing area code region (516). The overlay does not require you to change your existing area code or phone number, or how you dial your calls. You will continue to dial the area code and phone number for all local calls, as you do today, within and between the 516 and new 363 area codes.

 

Who is affected and when does the new 350 area code become effective?

Beginning January 20, 2023, customers in the 516 area code overlay region may be assigned a number in the new 363 area code when they request new service or an additional line. Customers receiving a 363 area code will be required to dial the area code and phone number for all local calls, just as customers with telephone numbers from the 516 area code do today.

 

What will you need to do?

Customers in the overlay region should:

  • Continue to dial 10 digits for all local calls, including calls within the same area code.
  • Continue to identify your telephone number as a 10-digit number, and include the area code when giving the number to friends, family, business associates, customers, etc.
  • Ensure that all services, automatic dialing equipment, or other types of equipment recognize the new 363 area code as a valid area code and continue to store or program telephone numbers as 10-digit numbers. Some examples are: stored telephone numbers in contact lists in wireless phones, PBXs, fax machines, Internet dial-up numbers, speed dialers, call forwarding settings, voicemail services, medical alert devices, safety alarm security systems and gates, ankle monitors and or other similar equipment.
  • Check items such as your website, personal and business stationery and printed checks, advertising materials, contact information, and your personal or pet ID tags to ensure the area code is included.

 

What will remain the same?

  • Your telephone number, including current area code, will not change.
  • The price of a call, coverage area, or other rates and services will not change due to the overlay.
  • What is a local call now will remain a local call.
  • You will continue to dial 10 digits for local calls within and between the overlay area codes, and 1+10 digits for long distance calls.
  • You can still dial just three digits to reach 911, as well as 211, 311, 411, 511, 611, 711, 811, or 988 if those are currently available in your community.

NOTICE NEW AREA CODE TO BE ADDED TO THE 213/323 AREA CODE REGION

The California Public Utilities Commission (CPUC) will begin the process to introduce a new area code to the 213/323 area codes, as the supply of available phone numbers in the 213/323 area code region is expected to be depleted by June 2025. Pending approval by the CPUC, the new area code will be introduced on top of the 213/323 area code region.

 

The 213/323 area code region was formed in 2017 when the 323 area code underwent an overlay that eliminated the boundary between the 213 area code region and the neighboring 323 area code region. The resulting combined 213/323 region is thus served by both the 213 and the 323 area codes. The new area code, if approved by the CPUC, will be the third area code for the region.

 

The CPUC has made available a recorded webcast to inform the public about the new area code. Topics to be discussed in the recorded webcast include: (1) History of the 213/323 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 November 18, 2022. Comments about the addition of the new area code may be submitted to the CPUC Public Advisor's Office by e-mail at public.advisor@cpuc.ca.gov, or by postal mail to 505 Van Ness Ave., San Francisco, CA 94102 by January 18, 2023. 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.

The New 350 Area Code is Coming to the California 209 Area Code Region

The 209 area code serves all or portions of Alameda, Alpine, Amador, Calaveras, Eldorado, Fresno, Madera, Mariposa, Merced, Sacramento, San Joaquin, Stanislaus, and Tuolumne counties, and encompasses cities such as Angels Camp, Atwater, Ceres, Dos Palos, Escalon, Galt, Gustine, Hughson, Ione, Lathrop, Livingston, Lodi, Los Banos, Manteca, Merced, Modesto, Newman, Oakdale, Patterson, Plymouth, Ripon, Riverbank, Sonora, Stockton, Tracy, Turlock, and Waterford.

What is an Area Code Overlay?

An overlay is the addition of another area code (350) to the same geographic region as an existing area code (209). The overlay does not require you to change your existing area code or phone number, or how you dial your calls. You will continue to dial 1+10 digits (area code + phone number) for all local calls, as you do today, within and between the 209 and 350 area codes. Mobile phone customers will continue to dial either 10 digits or 1+10 digits.

 

Who is affected and when does the new 350 area code become effective?

Beginning November 28, 2022, customers in the 209 area code region may be assigned a number in the new 350 area code when they request new service or an additional line. Customers receiving the 350 area code will be required to dial the 1+10 digits for all local calls, just as customers with telephone numbers from the 209 area code do today. Mobile phone customers receiving 350 numbers may dial either 10 digits or 1+10 digits.

 

What will you need to do?

Customers in the overlay region should:

  • Continue to dial 1+10 digits for all local calls, including calls within the same area code.
  • Continue to identify your telephone number as a 10-digit number, and include the area code when giving the number to friends, family, business associates, customers, etc.
  • Ensure that all services, automatic dialing equipment, or other types of equipment recognize the new 350 area code as a valid area code and continue to store or program telephone numbers as 10-digit numbers.
