This table lists all active area codes and some upcoming new area codes in numerical order, with a brief description of the location. If you need greater detail on the cities within that area code, please refer to the table at <http://www.LincMad.com/cities.html> For listings by prefix, you may wish to refer to <http://www.nanpa.com/reports/reports_cocodes.html> (on a different web site), which has official listings of assigned prefixes in various formats. Select "Central Office Code Utilized Report" for most queries. If you need to find the new area code for an old telephone number, try the cumulative listing of area code splits at <http://www.LincMad.com/newareacodes.html>
Area codes shown in green are future splits or overlays not yet in use. For example, area code 270 will split in 2012. The notation "assignment withdrawn" indicates a code that was assigned for a split or overlay (or other purpose) that was later cancelled or postponed indefinitely. Note: area codes in Canada are listed in blue; other non-U.S. or premium-charged area codes are in red.
All of the area codes below are in the North American country code +1. If you are looking for an international telephone code, please refer to the Internet and Telephone Country Code listing, or the new page specifically for Africa.

The state of Utah planned 385 as a geographic split of area code 801, back in 2001. The planned split was postponed, postponed again, postponed yet again, and finally cancelled. It was resurrected and finally implemented as an overlay on 2009-03-29.
Following Hurricane Katrina, lower Plaquemines Parish, Louisiana — the Mississippi River Delta area — was realigned from area code 985 back to 504. Buras, Pointe à la Hache, Port Sulphur, and Venice were affected. The (985) 358, 534, 564, 644, 687, and 814 prefixes changed back to (504); the (985) 238 and 333 prefixes changed to (504) with new 7-digit local numbers.
