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)
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.
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)
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.
ALL CUSTOMERS WITH SOUTH CAROLINA 803 AREA CODE MUST DIAL
AREA CODE + TELEPHONE NUMBER
FOR ALL LOCAL CALLS BEGINNING APRIL 25, 2020
Get ready to change the way you dial your local calls! To ensure a continuing supply of telephone numbers, the new 839 area code will be added to the area served by 803. This is known as an area code overlay.
To complete local calls, the new dialing procedure requires callers to dial area code + telephone number. This means that all local calls in the 803 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 assigned to the new 839 area code.
Beginning April 25, 2020, you must use the new dialing procedures for all local calls. After this date, if you do not use the new dialing procedures, your calls will not complete and a recording will instruct you to hang up and dial again. All customers can begin using the new dialing procedure before April 25, 2020.
The 803 area code generally covers the west central portion of the state serving communities such as Aiken, Allendale, Chester, Columbia, Lancaster, Orangeburg and Sumter. The new 839 area code will serve the same geographic area currently served by the existing 803 area code.
To ensure a continuing supply of telephone numbers, the 839 area code is being added to the area served by the 803 area code. Since two area codes will now serve the same geographic region, the area code must be used when dialing any telephone number—including calls within the same area code.
Beginning May 26, 2020, new telephone lines or services may be assigned numbers with the new 839 area code. Callers must use the new dialing procedure for local calls in the new 839 area code.
In addition to changing your dialing procedures, 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, stored telephone numbers in contact lists in phones, PBXs, fax machines, Internet dial-up numbers, alarm and security systems or gates, speed dialers, call forwarding settings, voicemail services, etc. You may also want to check your business stationery or advertising materials to ensure the area code is included.
