(256) Area Code Business Phone Numbers
The 256 area code covers northern Alabama from Huntsville out to Florence and Gadsden, split off from 205 back in 1998 as the Tennessee Valley kept filling up. Pick up a (256) number in the Tonet dashboard and start taking calls the same afternoon.
Get a 256 NumberAbout the 256 Area Code
256 was carved out of Alabama's original 205 code in 1998, when the Tennessee Valley and the Shoals had outgrown the old numbering plan. It still covers almost everything north of Birmingham, from the Tennessee line down through Gadsden and across to the Mississippi border at Florence.
Huntsville is now the largest city in Alabama, with about 249,102 residents as of mid-2025[1], and the metro ranks fifth in the country for aerospace and defense manufacturing investment[2]. That mix of government contractors, biotech shops, and the small businesses that feed them means a (256) number sits in good company whether you're an HVAC crew in Decatur or a consulting outfit near Cummings Research Park.
A local number still matters here. People in Madison and Florence recognize 256 on the caller ID and are more likely to pick up, and the engineers in Research Park tend to trust a local business over an 800 number cold-calling them. If you already have a (256) number with another carrier, you can port it over to Tonet at no charge, and most ports complete in 7 to 10 business days, sometimes longer depending on your current carrier.
Cities Served by the 256 Area Code
The 256 area code reaches across the top third of Alabama, from the Shoals in the northwest through the Tennessee Valley and down to Gadsden and Anniston in the east.
What You Get With a (256) Number From Tonet
Every feature is on both plans, so a two-person shop in Madison gets the same phone system as a thirty-seat office off Governors Drive. Here's what matters most for a small business in north Alabama.
Auto Attendant
Record a greeting, press 1 for sales, 2 for service, and send after-hours calls straight to voicemail. Nest menus as deep as you need, and set a separate schedule for Iron Bowl Saturday.
Call Recording
Flip recording on per number, incoming and outgoing. Transferred legs can record too, which helps when a Redstone contractor call bounces across three people before anyone writes anything down.
AI Transcription
Recorded calls get a searchable transcript with speaker labels, and every voicemail arrives in your email with the audio and a transcript in the body. Answered calls get a short summary with the next step.
Business SMS
Text from your (256) number so customers see the same local line they called. Receiving works right away, sending needs a one-time 10DLC carrier registration you file from the dashboard.
Mobile App
iOS and Android apps share the same login as the dashboard, so a plumber in Decatur can take a call from the truck and the office still sees the conversation in the thread.
Daily Billing
Plans start at $10 per user per month, billed daily against a prepaid balance. Add a user when you hire, pay those days only, delete them when they move on, and the charge stops.
Frequently Asked Questions
Can I get a (256) number if my business isn't in Alabama?
Yes. Numbers are bought by area code in the Tonet dashboard, and there's no address or business license check tied to the area code. If you want a Huntsville presence while your team sits in Austin or Manila, that works.
How long does it take to port my current (256) number over?
Most ports complete in 7 to 10 business days, sometimes longer depending on your current carrier. The port form is signed on screen, you upload your account bill as proof, and your number keeps working with your old provider until the switch, no downtime. Porting in costs nothing.
What does a (256) number cost each month?
The number itself is $2.50 per month. On top of that, the Pay As You Go plan is $10 per user per month plus a penny a minute and three cents a text, and Unlimited is $15 per user per month for US calls and texts under a fair-use policy. No contract, no seat minimum.
Will my (256) number work on a desk phone?
Yes. Tonet works with standard SIP desk phones from Yealink, Grandstream, Poly, Cisco, and Fanvil, and you can order a pre-configured Yealink shipped to a continental US address with $100 of calling credit included. It also works in the browser and in the iOS and Android apps with the same login.
Can I use a (256) number for 2FA codes from my bank?
Honestly, probably not. A Tonet number is a VoIP number, and US banks and services like PayPal or Coinbase usually refuse one-time codes to VoIP lines. Other apps are case by case and change their rules. If 2FA is the main reason you want the number, a US SIM is the dependable route.
