Area codes 430 and 903, Telephone area codes in northeastern Texas, United States.
Area codes 430 and 903 serve numerous communities across northeastern Texas, including the cities of Tyler, Longview, and Paris. The region spans multiple counties with a mix of urban and rural areas connected through these numbers.
Area code 903 emerged in 1990 from a split of the original area code 214, created to manage growing telephone demand. Overlay code 430 was added in 2003 to provide additional capacity without disrupting existing service.
These area codes connect communities that maintain agricultural traditions and hold annual county fairs throughout the region. Residents use these numbers to stay linked to local markets and community gatherings.
Residents and visitors in these area code zones need to dial the full ten-digit number for all calls due to the overlay system in place. This means there is no distinction between local and long-distance calls when dialing.
Before serving Texas, area code 903 was originally assigned to northwestern Mexico and connected with the United States through Telefonica Fronteriza. This cross-border history reflects the early days of international telephone networks.
