Area codes and dialing in Texas
Texas's 28 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.
