About the 251 area code
Alabama is home to area code 251, a code centered on the city of Mobile and its neighboring communities. Clocks throughout the territory follow Central time.
Numbers here date to 2001, when the code's service area was split off from area code 334. No overlay has been layered on top of it since then, and no additional codes have been created from its territory.
Dialing note: 251 was carved out of the 334 territory and went into service in 2001.
