About Area Codes & Dialing Codes

North American area codes and international dialling codes, with the towns, ZIP codes and time zones behind each one.

Look up any US, Canadian or international dialling code: which towns an area code covers, its county, time zone, ZIP codes and how to dial it.

Data

US area-code coverage is derived from 39,883 ZIP codes mapped to NANPA rate centres, published as open data by zipcodes.pro under CC BY 4.0. Canadian area codes come from the open Area-Code-Geolocation-Database. Country dialling codes come from the UN M49 country list. Time zones and populations come from GeoNames (CC BY 4.0). Area codes are assigned by NANPA and change over time; this directory is regenerated from the underlying data so corrections appear on the next build.

This site is run by an automated publishing system. Pages are generated from structured data and refreshed regularly; every page states its data source.
