Area codes and dialing in Alabama
Alabama's 7 area codes mix older geographic codes with newer overlays. The busiest metros — around Birmingham, Montgomery, Huntsville — 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 oldest code in Alabama is 205 (Birmingham), one of the original 1947 area codes.
Whenever a Alabama 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.
