The 256 area code covers the northern third of Alabama — anchored by Huntsville, the "Rocket City" that builds spacecraft and missiles, and stretching west to the music towns of the Shoals and east to Gadsden. It shares the region with the 938 overlay, and together they cover everything from NASA's Marshall Space Flight Center to the Tennessee River valley.

This guide explains where 256 reaches, how the 938 overlay works, the Rocket City economy that drives it, the nearby area codes, how businesses use a 256 number, and how to get one from anywhere.

The 256 area code covers north Alabama — the top third of the state, from the Mississippi line in the west to the Georgia line in the east, along and around the Tennessee River. It was created in 1998 when it split from Birmingham's 205.

256 and 938: north Alabama's overlay

When 256 itself began to run low, regulators added 938 as an overlay in 2010 rather than split the region again. A 938 number covers the exact same north-Alabama geography as a 256 — the two simply share the territory. Because two codes overlap, 10-digit dialing is required for every local call.

A 256 number is the older, more established of the pair; a 938 is more recently issued. For another two-code overlay in the same state, see Alabama's Gulf-coast neighbor 251 area code down in Mobile.

Rocket City: Huntsville's space-and-defense engine

Huntsville is the reason north Alabama punches far above its size. NASA's Marshall Space Flight Center and the sprawling Redstone Arsenal make the city one of the country's great centers of aerospace and defense engineering, surrounded by the labs of Cummings Research Park. Tourists pour into the **U.S.

Space & Rocket Center** beneath its towering Saturn V. West along the Tennessee River, Florence and the Shoals carry a different legacy — the recording studios that gave the world "Muscle Shoals" soul. It is a region where a 256 number might ring at a rocket contractor, a river-port plant, or a recording studio.

Business uses for a 256 number

Four cards showing 256 uses: support line, sales, marketing and multi-location

A 256 number works as a local identity across north Alabama. Businesses put one to use in a few common ways:

  • Local support line — Huntsville and Decatur customers reach you on a number they recognize.
  • Sales and outreach — a 256 caller ID earns more callbacks than an unknown out-of-state number.
  • Local marketing — a 256 number on an ad or vehicle reads as north-Alabama local.
  • Multi-location — give each office its own local number while routing to one team.

You do not need an office in Cummings Research Park to set this up. My Country Mobile can assign you a 256 number and route it to the phones, laptops, and apps your team already uses, anywhere in the world.

Dialing and time zone

Because 256 and 938 share one region, 10-digit dialing is required — every local call needs the full area code. The 256 area code sits in the Central Time Zone (CT)America/Chicago — observing CST (UTC−6) in winter and CDT (UTC−5) in summer.

Staying safe from 256 scam calls

Like any local code, 256 gets spoofed. Scammers fake a 256 caller ID — sometimes matching the first digits of your own number — so a call looks like a nearby business or county office. A 256 on your screen does not prove the caller is really in Alabama.

A few habits keep you safe:

  • Let unknown 256 calls go to voicemail; legitimate callers leave a message.
  • Never share one-time codes, card numbers, or login details with an inbound caller.
  • Be wary of "utility shutoff," "warrant," or benefits-style calls that pressure you to act fast.
  • Use carrier spam filtering. The FCC's STIR/SHAKEN call authentication framework is why many phones now flag these as "Spam Risk."

How to get a 256 number

Getting a 256 line takes minutes, with no Alabama address required. A cloud phone provider can assign you one and route calls to the devices your team already uses:

  1. Sign up for a free account — no card needed to browse inventory.
  2. Search 256 (or 938) and pick a number from available north-Alabama inventory.
  3. Choose a plan by seat count and features.
  4. Route and go live — send calls to a cell, desk phone, or softphone.

Porting an existing 256 or 938 number runs 5–10 business days in the background while you stay live on a temporary number.
