((green) = not yet in use; see "About these Tables" for more information)
This listing has been divided into separate pages as follows:
To find a specific area code if you don't know what state it's in, refer to the Locator page, which lists all active area codes numerically — Now with Time Zones! — or refer to the Numeric Cross-Reference Table on the main cities.html listing page. If you want a listing by prefix, <http://www.nanpa.com/reports/reports_cocodes.html> (on a different web site) has information on prefix (Central Office Code) assignments.
Time Zones are color-coded: Pacific, Mountain, Central, Eastern, and Atlantic; other miscellaneous time zones are not shaded. Where two times are shown, the second is Daylight Saving Time, in effect from the second Sunday of March until the first Sunday of November — for example, from 2012‑03‑11 until 2012‑11‑04. If only one time is shown, that area does not observe DST. To convert to international standard time notation (offset from GMT/UTC), subtract 12 hours from the time shown; for example, Eastern Standard Time is shown as 7:00, corresponding to UTC–05:00.

The U.S. tables give the area codes for each state, with a list of important cities and towns in each area code. Weight is given to population and also to proximity to the border with an adjoining area code. Area codes shown in parentheses in (green) are not yet in use; in each such case, the area code immediately above in the table applies to the listings shown in green. The Canada table follows the same format for the provinces and territories. The Caribbean/Other Island territory table lists the territory or country with major islands or cities. Unless otherwise indicated, the island is an independent nation located in the Caribbean. The Nearby Country Codes table lists non-NANP international country codes for selected areas adjacent to the NANP. There is a complete listing of all country codes on the countrycodes.html page on this site.
