What is an area code?

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.

How do I find the area code for a city?

Use the area code directory on this page: type a city, state, or three-digit code and the matching regions appear instantly. You can also browse the popular US area codes and the lookup-by-region sections below.

What is the difference between an area code and a country code?

A country code routes a call to a nation (for example +1 for the United States), while an area code routes it to a region within that nation. You dial the country code first when calling from abroad, then the area code, then the local number.

Can two cities share the same area code?

Yes. A single area code can cover several nearby cities or an entire metro region. As demand for numbers grows, regions are often split or given an additional overlay area code that serves the same geography.

What are toll-free area codes?

Toll-free numbers use special prefixes — 800, 833, 844, 855, 866, 877, and 888 — instead of a geographic area code. The business that owns the number pays for incoming calls, so they are free for the caller. They are popular for customer support and sales lines.

What time zone is area code 712 in?
