An area code overlay is a numbering plan area (NPA) in the North American Numbering Plan (NANP) that has multiple area codes assigned. Overlay complexes are used to add central office prefixes in an NPA to increase the number of available telephone numbers. [1]
This is a list of area codes in the Commonwealth of Virginia. 276 — Southwest corner of the state including Bristol, Galax, Martinsville, and Wytheville (September 1, 2001 as split from 540). 434 — South central area including Charlottesville and Lynchburg (June 1, 2001 as split from 804).
Central office code protection made it possible in some low-density areas to use seven digits to reach areas in another area code. Examples: Washington, D.C. ( area code 202 ) to adjacent areas of Maryland ( area code 301 ) and Virginia ( area code 703 ), discontinued on October 1, 1990, to allow assignment of a code in all three area codes.
Area codes are also assigned for non-geographic purposes. The rules for numbering NPAs do not permit the digits 0 and 1 in the leading position. [1] Area codes with two identical trailing digits are easily recognizable codes (ERC). NPAs with 9 in the second position are reserved for future format expansion.
