About Area Code 938
Area code 938 is a North American Numbering Plan (NANP) area code that has been in service since 2010. It is administered by NANPA on behalf of the FCC and serves the Alabama region anchored on Huntsville.
938 is an overlay code, which means it shares its geographic boundaries with one or more existing area codes (256). Overlays are created when a region exhausts the supply of phone numbers in its original area code. Within an overlay region, residents must dial all 10 digits even for local calls, because the same 7-digit number can exist under multiple area codes.
Mobile numbers in 938 are portable: a person who moved away from Huntsville may still carry a 938 mobile number on their device. If you receive an unexpected call from a 938 number, run it through the reverse lookup tool above for the most accurate, free identification.
If you live or do business in Alabama, you may also interact with neighbouring or overlay codes (256). See the related codes section below to explore the rest of Alabama.
