Find Area Code by City
Enter a city name to find the area code(s) that serve it. Covers all major US, Canada, and Caribbean cities.
How to find the area code for a city
Type the city name into the search box above. The tool searches through all 408 active NANP area codes and matches against the primary city assigned to each code. Results link directly to the area code detail page, where you'll find county and city breakdowns, carrier info, prefixes, history, and spam-risk assessment.
Note that some large cities have multiple area codes (overlays). For example, New York City has 212, 332, 646, and 917; Los Angeles has 213, 310, 323, 424, 747, and 818. Searching for "New York" will return all matching codes.
If you don't know the exact city name, try searching by state — for example, "Idaho" will return all 2 area codes serving Idaho (208 and 986).
Why cities have multiple area codes
When a city's demand for phone numbers exceeds the capacity of a single area code (~7.9 million numbers), regulators add an overlay code that shares the same geographic territory. This is why Manhattan now has four codes (212, 332, 646, 917, and the upcoming 929) and Atlanta has four (404, 470, 678, 943). Overlay codes were introduced in the 1990s as a less disruptive alternative to geographic splits, which required existing customers to change their phone numbers.
