Area Code Overlay Information

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 on 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.

New 689 Area Code is Coming to the 407/321 Region in Central Florida

New 689 Area Code is Coming to the 407/321 Region in Central Florida

To ensure a continuing supply of new telephone numbers, the Florida Public Service Commission has approved an all services area code overlay for the 407/321 overlay region, which currently serves Orange, Osceola, and Seminole Counties, as well as parts of Lake and Volusia Counties. The new 689 area code will be “overlaid” or superimposed over the region now served by the 407/321 overlay. The portion of the 321 area code serving Brevard County is not affected and will not receive the 689 overlay.

What is an area code overlay?

This overlay is the addition of another area code (689) to the same geographic region as existing area codes (407/321). This overlay does not require customers to change their existing area code or phone number, or how they dial their calls.

Who will be affected and when will the change begin?

Beginning June 4, 2019, customers in Orange, Osceola, and Seminole Counties, as well as parts of Lake and Volusia Counties, may be assigned a phone number in the new 689 area code when requesting new service, an additional line, or in some cases, moving their service. The 689 area code will co-exist everywhere in this region with the 407/321 area codes. Customers with 321 phone numbers serving Brevard County are not affected.

What will customers need to do?

Customers in Orange, Osceola, and Seminole Counties, and the parts of Lake and Volusia Counties served by the 407, 321 and 689 area codes overlay should:

  • Continue to dial 10 digits for all local calls within the overlay region.
  • Continue to identify their telephone numbers 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 689 area code as a valid area code, and continue to program telephone numbers with 10-digit telephone numbers. Some examples are: stored phone numbers in contact lists in wireless and cordless 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, or other similar equipment.
  • Check their websites, business stationery, advertising materials, personal and business printed checks, contact information, and personal or pet ID tags to ensure the area code is included.

Customers with 321 phone numbers serving Brevard County are not affected, and may continue to dial just 7 digits for local calls within the 321 area code.

What will remain the same?

  • Customers’ telephone numbers, 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 regardless of the number of digits dialed.
  • Customers in the overlay region will continue to dial 10 digits for local calls within and between the overlay area codes, and 1+10 digits for long distance calls and operator-assisted calls.
  • Customers in Brevard County will continue to dial 7 digits for local calls within the 321 area code, 10 digits for local calls to other area codes, and 1+10 digits for long distance calls and operator-assisted calls.
  • Customers can still dial just three digits to reach 911, as well as 211, 311, 411, 511, 611, 711 or 811 if those are currently available in their community.

New Dialing Procedure Required for New Jersey 609 Local Calls
And for All Calls Between the 609 and 856 Area Codes
Beginning August 18, 2018

The new 640 area code is being added to the same geographic area currently served by area code 609. This process is known as an area code overlay, and requires a new dialing procedure. An overlay does not require customers to change their existing area code, but does require them to dial the area code and the seven-digit telephone number on calls within the same area code.

Also in connection with this overlay, the new dialing procedure requires the inclusion of the area code for all calls between the 609 and 856 area codes.

What is the new dialing procedure?

To complete calls from a 609 area code to another 609 area code telephone number, the new dialing procedure requires callers to dial the area code + telephone number. This means that all calls within the 609 area code that are currently dialed with seven digits will need to be dialed using ten digits, that is, the area code + telephone number. The same dialing procedures will apply to telephone numbers assigned to the new 640 area code.

In addition, calls made from the 609 area code to the 856 area code that are currently dialed with seven digits will need to be dialed using 1 + area code + telephone number. The same dialing changes will apply to calls made from the 856 area code to the 609 area code. Local calls made within the 856 area code can continue to be dialed with just seven digits

Following is a summary of the new dialing procedures:

Call From Call To New Dialing Procedure
609 or 640 609 or 640 Area code + 7-digit telephone number
609 or 640 856 or any area code other than 609 or 640 1 + area code + 7-digit telephone number
856 609 or 640 or any area code other than 856 1 + area code + 7-digit telephone number
856 856 7-digit telephone number

Who will be affected?

Anyone with a 609 area code is affected. The 609 area code serves portions of central and southeastern New Jersey, and the new 640 area code will serve that same geographic area.

In addition, anyone with an 856 area code using just seven digits to dial calls from the 856 area code to the 609 area code is affected.

Why is the change necessary?

To ensure a continuing supply of telephone numbers, the new area code 640 is being added to the same geographic area currently served by the existing area code 609. Since two area codes will now serve the same geographic region, seven-digit dialing in the 609 area will be eliminated and the area code must be used when dialing any telephone number, including calls within the same area code

Beginning September 17, 2018, new telephone lines or services may be assigned numbers with the new 640 area code. Callers must also use the new dialing procedure for local calls in the new 640 area code.

When will the change become mandatory?

Beginning August 18, 2018, you must use the new dialing procedure for all local calls. If you do not use the new dialing procedure, your call will not be completed, and a recording will instruct you to hang up and dial again.

However, all customers should begin using the new dialing procedure before August 18, 2018.

What will you need to do?

In addition to changing your dialing procedures, all services, automatic dialing equipment, or other types of equipment that are programmed to dial a seven-digit number from a 609 area code will need to be reprogrammed to use the new dialing procedures, as well as any equipment that is programmed to dial a seven-digit number from a 856 area code to a 609 area code telephone number. (Equipment programmed to dial a seven-digit number from an 856 area code to an 856 area code does not need to be reprogrammed.) Some examples of such equipment are life safety systems and medical monitoring devices, stored telephone numbers in contact lists in phones, PBXs, fax machines, ankle monitors, Internet dial-up numbers, alarm security systems and gates, speed dialers, call forwarding settings, voicemail services, etc. Please contact your medical alert or security provider if you don’t know whether your equipment needs to be reprogrammed to accommodate the new dialing procedures. 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?

  • 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 or the change in dialing procedures.
  • What is a local call now will remain a local call regardless of the number of digits dialed.
  • You will continue to dial 1+ area code + telephone number for all calls to other area codes.
  • You can still dial just three digits to reach 911, as well as 211, 311, 411, 511, 611, 711 and 811.

All Customers with 619 and 858 Area Codes must dial 1 + Area Code + Telephone Number for ALL calls beginning May 19, 2018

To ensure a continuing supply of telephone numbers, the boundary line between the 619 and 858 area codes will be eliminated and the two areas served by the 619 and 858 area codes will be combined. This is known as a boundary elimination overlay. The boundary elimination overlay does not require customers with a 619 or 858 area code to change their existing area code, but does require them to dial “1” followed by the area code and the seven-digit telephone number on every call, including calls within the same area code.

Who will be affected?

Everyone with a 619 or 858 area code is affected. The 619 area code principally serves the southern portion of the City of San Diego and the adjacent cities of Chula Vista, Coronado, El Cajon, Imperial Beach, La Mesa, Lemon Grove, National City, Santee and unincorporated areas of San Diego County. The 858 area code serves the northern portion of the City of San Diego along with the adjacent cities of Del Mar, Poway, Solana Beach and a small portion of the City of Encinitas, as well as an unincorporated area of San Diego County. Once the boundary elimination area code overlay is implemented, both area codes will serve the combined region.

What is the new dialing procedure?

To complete calls from a landline phone, the new dialing procedure requires anyone with a 619 or 858 area code to dial 1 + area code + telephone number. This means that all calls in the 619 and 858 area codes that are currently dialed with seven digits will need to be dialed using 1 + area code + telephone number.

To complete calls from a cellular or mobile phone, callers may dial the area code + telephone number or 1 + area code + telephone number whenever placing a call from a phone number with the 619 or 858 area code.

When will the new dialing procedure become mandatory?

Beginning May 19, 2018, you must use the new dialing procedure, even for local calls. After this date, if you do not use the new dialing procedure, your calls will not be completed and a recording will instruct you to hang up and dial again using the new dialing procedure.

Beginning June 19, 2018, new telephone lines or services in the former 619 region may be assigned numbers using the 858 area code, and conversely, new telephone lines or services in the former 858 region may be assigned numbers using the 619 area code.

What will you need to do?

In addition to changing your dialing procedure, 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 use the new dialing procedures. Some examples are life safety systems and medical monitoring devices, ankle monitors, PBXs, fax machines, Internet dial-up numbers, alarm and security systems or gates, speed dialers, call forwarding settings, voicemail services, stored telephone numbers in contacts lists in wireless or cordless phones, and other similar services or equipment. Many systems operate on 1+10-digit or 10-digit dialing by default, but some older equipment may still use 7 digits. Please contact your medical alert or security provider if you do not know whether your equipment needs to be reprogrammed to accommodate for the upcoming change to 1+10-digit dialing. You may also want to check your personal and business stationery and checks, advertising materials, websites, contact information, and 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 regardless of the number of digits dialed.
  • You can still dial just three digits to reach 911, as well as 211, 311, 411, 511, 611, 711 and 811

What is an area code overlay?

An area code overlay is the addition of another area code (341) to the same geographic region served by an existing area code (510). 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.
