Mobile, AL Area Code

Area code serving Mobile

Mobile sits in Alabama, part of the South region and the Central Time zone. Its area code is 251, which covers Mobile, Baldwin County and the rest of southwestern Alabama including the Gulf Coast. 251 has no overlay today, so every Mobile landline and mobile number with a local code starts with 251.

251 has served the area since 2001. If the region runs low on numbers, regulators will most likely add an overlay code on top rather than split the area, which would make 10-digit dialing mandatory.

Getting a Mobile phone number

Any new landline, mobile or VoIP number from a local carrier in Mobile gets the 251 area code. Numbers come from the blocks each carrier holds in the area; a number ported in from elsewhere keeps its original area code, so you may also see out-of-state codes locally.

Dialing in Mobile

Mobile is covered by the single area code 251 with no overlay, so some local calls may still connect with seven digits. Dialing all 10 digits (area code + seven-digit number) always works and is the safest habit. From outside the US, dial +1, then the area code and number. See 10-digit dialing and overlay area codes for the background. For every code in Alabama, visit the Alabama area codes page.
