Area codes and dialing in Texas
Texas's 29 area codes mix older geographic codes with newer overlays. The busiest metros — around Abilene, Austin, Beaumont — carry the most numbers and rely on overlays, which is why 10-digit dialing is required there. Quieter parts of the state may still use a single code. The original code in the Texas list is 210 (San Antonio).
Whenever a Texas region runs low on numbers, a new overlay is added on top rather than splitting the map, so existing customers keep their numbers. See 10-digit dialing for what that means in practice, or the newest area codes for upcoming changes.
Cities with multiple area codes
These Texas metros are served by an overlay of two or more codes, so 10-digit dialing applies: Houston · Dallas · Austin · Fort Worth · San Antonio · Tyler.
