What is a US area code?

An area code is the three-digit prefix after +1 that ties a US number to a region. Managed under the NANP, busy metros get an overlay code over the same area — which is why some cities have two or three.

  • Tied to geography. Each code maps to a defined state region, so callers recognize where you are.
  • Governed by the NANP. A shared plan keeps every US and Canadian code globally unique.
  • Overlays add capacity. Busy metros get a second code layered over the same map.
Know the difference

Local vs toll-free vs mobile area codes

Local

212, 415, 312…

Geographic codes tied to a city or metro — local callers pick up local numbers.

  • Maps to a real region
  • Trusted by nearby callers
  • Ideal for local sales & support

Toll-Free

800, 833, 888…

Non-geographic numbers — free for the caller, perfect for national support lines.

  • Free for the caller
  • National, not regional
  • Great for inbound support

Mobile

Same as local

US cell phones share the same area codes as landlines, tied to where they were first activated.

  • No mobile-only prefix
  • Follows the original region
  • Portable between carriers
For teams

Why area codes matter for your business

A local area code builds instant trust — customers answer calls from familiar codes.

Use one plan to cover every market, no extra offices or phone systems needed.

Look local, win local

A familiar area code signals you're part of the community. Local callers pick up and call back more readily than they do for unknown or out-of-area numbers.

Expand without offices

Claim numbers in any city's area code to enter new markets — no storefront or second phone system required. Just pick the code and start taking calls.

Boost answer rates

Calls from a recognized local code are far less likely to be ignored or flagged as spam than out-of-area or toll-free numbers.

One system, every code

Run dozens of area codes through a single letsdial dashboard with unified routing, call recording, analytics, and voicemail — all on one plan.

Area code FAQs

Questions about US area codes

An area code is the three-digit prefix at the start of a North American phone number that identifies a specific geographic region — a city, metro area, or part of a state. In the number (212) 555-0100, the 212 is the area code for Manhattan in New York City.
