To ensure a continuing supply of telephone numbers, the new area 640 code is being added to the same geographic area currently served by the existing 609 area code in New Jersey. This process is known as an area code overlay, and requires a new dialing procedure.
In connection with this overlay, all seven-digit dialed calls between area codes 609 and 856 will be eliminated and will require a new dialing procedure.
What is an area code overlay?
An area code overlay is the addition of another area code (640) to the same geographic region as an existing area code (609). 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, all seven-digit dialed calls between area codes 609 and 856 will be eliminated and callers will be required to dial 1 + area code + seven-digit telephone number instead.
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.
How does this affect providers of Public Safety Answer Points (PSAPs)?
As a result of the overlay, any seven-digit programmed services and equipment must updated to the new dialing procedure as noted below. All PSAP equipment, such as speed dialers and call transferring equipment, located in the 609 area code and programmed to dial only seven digits, must be updated or reprogrammed to dial 10 digits (area code + telephone) for all local calls in the 609/640 area code. The same dialing procedure will apply to telephone numbers assigned to the new 640 area code.
In addition, any equipment currently programmed to dial seven digits from the 609 area code to the 856 area code must be updated to the new dialing plan (1+ area code + telephone number). The same dialing changes will apply for any equipment located in the 856 area code currently programed to dial only seven digits to the 609 area code. Local calls made within the 856 area code can continue to be dialed with just seven digits.
What will be the new dialing procedures?
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 procedure 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.
The following is a summary of the new dialing procedure:
|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|
When will the change begin?
Beginning August 18, 2018, you must use the new dialing procedures, as described above, for calls made from the 609 and 856 area codes. On and 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 area code.
Reprogramming of equipment/systems should be in progress and must be completed prior to the mandatory dialing date of August 18, 2018.
To enable you to verify that equipment can complete calls to the new 640 area code, a special test number, 640-990-TEST (8378), will be in service beginning June 6, 2018 and will remain active through October 17, 2018.
Beginning September 17, 2018, new telephone lines or services in the 609 area may be given numbers from the new 640 area code.
What will remain the same?
The price of a call, coverage area, or other rates and services will not change due to the overlay, and what is a local call now will remain a local call regardless of the number of digits dialed. Customers can still dial just three digits to reach 911, as well as 211, 311, 411, 511, 611, 711 and 811.
