Area codes 903 and 430 are telephone area codes in the North American Numbering Plan (NANP) for the northeastern part of the U.S. state of Texas, including Kilgore, Texarkana, Tyler, and Sherman. The numbering plan area begins just north and east of the Dallas–Fort Worth metroplex, and extends to the Oklahoma, Arkansas, and Louisiana state borders. Area code 903 was created November 4, 1990 in a split of area code 214. Area code 430 was assigned to the same service area on February 15, 2003 in creation of an overlay. Before October 18, 1980, area code 903 was assigned to an area in northwestern Mexico.
History
From 1962 until October 18, 1980, area code 903 was an area code for parts of northwestern Mexico served by Telefónica Fronteriza (TF), which homed on AT&T lines in the United States rather than Telefonos de Mexico (Telmex). Telmex and the Mexican government forcibly acquired the TF exchanges and, in 1980, Telmex reorganized the numbering plan of the country, using the digit 6 to start eight-digit numbers in the northwest. AT&T withdrew 903 from use and reassigned the area with area code 706,1 as one of two area codes (903 and 905) for alternative dialing into certain parts of Mexico from the United States.
