History of Area Code 430
Area code 903 entered service in 1990 after a geographic split from area code 214. Area code 430 was introduced in 2003 as an overlay for area code 903, so it did not divide the region or replace the older code.
The overlay added numbering capacity as telephone service expanded across northeastern Texas. Because 430 is an overlay, both 430 and 903 numbers can serve communities such as Longview, Tyler, and Marshall.
