What is 251

Area code 251 covers Coastal Alabama — Mobile's deepwater port (one of the US's top 10 busiest), Baldwin County's fast-growing Gulf Shores resort economy, and Airbus's US final assembly line at Mobile Aeroplex, the only commercial aircraft manufacturing facility in the American South.

WHY 251 · FOUR REASONS

Why choose a 251 number?

01

Serve Mobile's port and maritime economy

The Port of Mobile is one of the top 10 busiest ports in the US. Maritime, freight, and logistics businesses serving this Gulf Coast hub need a recognised 251 number.

02

Reach the Airbus manufacturing corridor

Airbus's only US manufacturing facility is in Mobile. Aerospace suppliers and contractors need a local number to operate credibly in this supply chain.

03

Connect with the Gulf Coast tourism market

Mobile's Mardi Gras (the original US Mardi Gras) and nearby Gulf Shores beaches drive significant tourism revenue. Hospitality and events businesses rely on a local 251 presence.

04

Southwestern Alabama since 2001

251 was split from 334 in 2001, giving Mobile and the Gulf Coast their own distinct identity — separating the port city from the Montgomery-centred central Alabama market.

14 FEATURES · ZERO ADD-ONS

Everything included on every 251 number.

Every 251 number ships with fourteen tools for coastal Alabama's port and aerospace economy — 24/7 call routing for Port of Mobile operations, IVR for Airbus's Mobile assembly line, and SMS for Gulf Shores' resort management teams.
