The 251 area code serves southern and coastal Alabama, including the port city of Mobile and the fast-growing beach communities of Baldwin County. Created in 2001 when it split from 334, 251 covers Alabama’s Gulf Coast and its only saltwater port.
Quick Summary of the 251 Area Code
| Area Code | 251 |
| State | Alabama (AL) |
| Region | Southern & Coastal Alabama (Mobile & Baldwin County) |
| Major Cities | Mobile, Daphne, Fairhope, Foley, Gulf Shores, Prichard, Saraland, Bay Minette |

Geographic Coverage
The 251 area code covers the southwestern corner of Alabama along the Gulf of Mexico, centered on the city of Mobile and its suburbs of Prichard and Saraland, and extending across Mobile Bay to the booming Baldwin County cities of Daphne, Fairhope, Foley, and the beach resorts of Gulf Shores, along with Bay Minette to the north. It borders Mississippi and Florida on the coast.
Time Zone
The 251 area code observes Central Time (CT). Clocks follow Central Standard Time (UTC−6) in winter and shift to Central Daylight Time (UTC−5) from mid-March through early November. All of Alabama is on Central Time. From the West Coast, this region is two hours ahead of Pacific Time, so a 9:00 AM call in California reaches a 251 number at 11:00 AM local time.
Tip: Business hours across the 251 region generally run 9:00 AM to 5:00 PM Central Time, Monday through Friday.
How to Dial a 251 Number
Area code 251 is not part of an overlay, so it has traditionally allowed 7-digit local dialing. However, 10-digit dialing is now the recommended nationwide standard, and dialing the full 10-digit number (251 + the line number) always works reliably. For international callers, dial your country’s exit code, then +1 (the North American country code), then 251, followed by the seven-digit local number.
Scam Alerts for the 251 Area Code
Like every U.S. area code, 251 has been used by scammers who spoof local numbers to appear trustworthy. Residents in Mobile, Daphne, Fairhope, Foley, Gulf Shores, Prichard, Saraland, Bay Minette should stay alert to the following common tactics:
| Scam Type | What to Watch For |
|---|---|
| IRS / Tax Scams | Callers impersonating the IRS and threatening arrest over supposed unpaid taxes. |
| Utility Shut-off | Fake Alabama Power callers demanding instant payment to keep your power on. |
| Vacation Rental Scam | Fraudulent Gulf Shores or Orange Beach rental listings that vanish after you pay a deposit. |
| Storm Repair Scam | Fake contractors demanding upfront payment for hurricane or storm damage repairs. |
If you receive a suspicious call from a 251 number, take these steps to protect yourself:
- Do not share personal information such as Social Security numbers, bank details, or passwords over the phone.
- Hang up and verify by calling the organization back using an official number from its website.
- Report the call to the FTC at reportfraud.ftc.gov and to the Alabama Attorney General’s Office.
- Block the number and consider registering with the National Do Not Call Registry.
Red Flag: Legitimate agencies such as the IRS, Social Security Administration, or your local utility company (Alabama Power or Huntsville Utilities) will never demand immediate payment by gift card, wire transfer, or cryptocurrency. Any 251 caller making such a demand is a scammer.
History and Economy of the 251 Region
n
Area code 251 was created in 2001, split from 334, to serve coastal Alabama. The regional economy is anchored by the Port of Mobile, the state’s only saltwater seaport and one of the busiest in the country, which drives a major shipping, shipbuilding, and logistics sector – Austal USA builds ships for the Navy here, and Airbus operates a final assembly line for commercial jets. Aerospace, chemicals, and oil-and-gas add to the industrial base, while Baldwin County across the bay is one of the fastest-growing areas in the state, powered by Gulf Coast tourism in Gulf Shores and Orange Beach and the growing cities of Daphne, Fairhope, and Foley.
