Area code 903 serves northeastern Texas, covering cities like Tyler, Longview, Texarkana, and Sherman. Introduced in 1990 as a split from area code 214, 903 was created to serve the growing population and economic activity outside the Dallas-Fort Worth metro area. The region blends small cities and rural communities with robust industries including manufacturing, agriculture, healthcare, and education. Tyler is a regional hub, known for its rose production, universities, and medical centers. Longview and Texarkana also contribute to the area’s economic landscape with logistics, oilfield services, and regional commerce. Tourism and local culture are enhanced by lakes, pine forests, and events like the Texas Rose Festival. Area code 903 is often paired with overlay 430, which was introduced in 2003 to meet number demand. The dual-code system ensures number availability while preserving the identity of long-standing 903 numbers. Whether you’re running a local business, reaching rural customers, or building a regional brand, the 903 area code helps establish a presence in East Texas—an area known for community values, low cost of living, and a strong work ethic.
