AREA CODE OVERLAYS

Due to the increasing use of overlays, the map now shows only the first area code in an overlay area, with a plus sign to indicate a current or planned overlay. The last two concentrated overlays, in Oregon and British Columbia, have been "unconcentrated," expanding to cover the entirety of the original area codes. Additionally, area code 778 in B.C. now overlays both 604 and 250, covering the entire province. In the table below, ".do" is the Dominican Republic. The states are slightly out of alphabetical order to avoid breaking a state across two columns.

Table Notations:
% concentrated overlay (new area code covers only part of old) [none remaining]
( ) overlay has not yet taken effect
@ 321 is a separate area code for the coastal area (the "Space Coast" of Florida), but also an overlay of the inland 407 area (including Orlando and DisneyWorld)
∗ one overlay code covers multiple original code areas

This map shows all telephone area codes in use as of 2010-02-01 in the United States and Canada. Area codes that have not yet taken effect are shown with a green line and the area code in parentheses. Some planned area codes that have been cancelled or indefinitely postponed are no longer shown. Check the separate page for information about the 19-way split in the Caribbean area. There is also a Caribbean map. Some of the area codes shown above are not yet in use. For information on the split dates of new area codes, see the table on the separate page. Detailed maps of some of the metropolitan areas may be added in the future, along with time-zone boundaries. All boundaries shown are approximate.

The following area codes (in the Caribbean/Atlantic) are not shown on the map

242	Bahamas	473	Grenada	784	St. Vincent & the Grenadines
246	Barbados	649	Turks & Caicos	809 829 849	Dominican Republic
264	Anguilla	664	Montserrat
268	Antigua & Barbuda	(721) NEW!	Dutch Sint Maarten, eff. 2010-05-31
284	British Virgin Islands			868	Trinidad & Tobago
345	Cayman Islands	758	St. Lucia	869	St. Kitts & Nevis
441	Bermuda	767	Dominica	876	Jamaica

ERRATA, UPDATES and NOTES:

• NEW! The island of Saint Martin in the Caribbean is divided into two territories. The north side is the French overseas collectivity of Saint-Martin; the south side is the Dutch municipality of Sint Maarten, currently part of the Netherlands Antilles. However, Sint Maarten is politically separating from the rest of the Netherlands Antilles, although it will remain a part of the Kingdom of the Netherlands. Along with the political change, Sint Maarten will also change from the current international country code of +599 (011–599 as dialed from North America) to the North American area code 721 (+1 721, for the rest of the world). This change will not affect French Saint-Martin (+590) nor the rest of the Netherlands Antilles (+599 and +297). The 7-digit number in Sint Maarten will generally consist of the current city code '5' plus the old 6-digit number.
  
  
• Plaquemines Parish, Louisiana — the Mississippi River Delta, the southeasternmost part of Louisiana — split from area code 504 into the new 985 area, back in 2001. However, in the aftermath of Hurricane Katrina, the boundary was realigned, with the Delta changing back to 504. Buras, Pointe-a-la-Hache, Port Sulphur, and Venice were affected, with numbers in the (985) 358, 534, 564, 644, 687, and 814 prefixes changing to (504). Additionally, numbers in (985) 238 and 333 changed to (504) with new 7-digit local numbers. The new (504) numbers are mandatory as of 2008-05-01.
  
  
• The western tip of Kentucky has an area code split now scheduled for 2012-01-01, with mandatory use a few months later. The split has already been postponed four times, and may yet be shifted again. The westernmost part (Paducah, Hopkinsville, Henderson) will change to 364; the eastern portion of the current 270 area (Bowling Green, Owensboro) will retain the 270 code.
  
  
• After numerous postponements, Utah has finally implemented the 801/385 overlay — originally slated as a split on 2000-12-31!
  
  
• Area code 760 in southern California was scheduled to split on 2008-11-08. The coastal area of northern San Diego County (Oceanside, Escondido) would have changed to 442; the inland areas from the Mexican border up the eastern Sierra Nevada almost to Lake Tahoe (Palm Springs, Death Valley) would retain 760. However, at the last minute the CPUC changed the split to an overlay. The new code will still be 442, but existing numbers in 760 will not change.
  
  
• The state of California has gone back and forth on the issue of overlays and splits. The 310 area code in the Los Angeles area has been congested for some time. A proposal was made to overlay, then the decision was made to split (but with very little notice from the "trigger date" until the split actually took effect), then the decision was made to overlay, and then that decision was reconsidered. The overlay finally took effect on 2006-07-26. Three additional overlays have added in southern California: 714 & 657 in northern Orange County, and 818 & 747 in Burbank and the San Fernando Valley area, plus the 760 & 442 overlay noted above.
  
  
• The northwestern corner of Oregon, including Portland, Salem, and Astoria, is served by the 503/971 overlay. The rest of Oregon is area code 541, which will add the 458 overlay code in 2010.
  
  
• Area code 909 in southern California was split on short notice. The northern portion (western San Bernardino County, plus a small portion of eastern Los Angeles County) retained 909, while western Riverside County changed to 951. (The eastern portions of Riverside and San Bernardino Counties are served by the 760 area code.) The previous plan to overlay the remaining 909 area with 752 was scrapped.
  
  
• Connecticut's two area codes were both scheduled to overlay several years ago, but the overlays were postponed several times. However, the 203 & 475 overlay is now in effect, and the 860 & 959 overlay is expected in 2011 or 2012.
  
  
• Three U.S. territories in the Pacific now have area codes. Guam is area code 671. The Commonwealth of the Northern Mariana Islands (incl. Saipan and Tinian) is area code 670. American Samoa is area code 684. All three can be dialed "one-plus" from the US and Canada, or using country code +1 from outside the NANP. However, note that the independent state of Samoa (formerly known as Western Samoa) retains country code +685 (i.e., dial 011–685). Furthermore, the CNMI's old country code +670 (i.e., 011–670) has been recycled for Timor-Leste (East Timor).
  
  
• Area code 407 in Florida performed a Double-Back-Somersault Reverse Concentrated Overlay with a Twist in which the "Space Coast" changed to only area code 321, while the Orlando area became an overlay of 407 and 321.

COLOPHON:
The map above is hand-drawn, using an underlay of the state and county maps in the Map Art collection from Map Resources <http://www.MapResources.com> The data for the map is compiled from various telecom industry sources, including state regulatory agencies, local exchange carriers, and published telephone listings. The map uses a Plat Carré projection. The map and all derivative works are copyrighted, with the copyright registered with the United States Library of Congress. Commercial use requires written permission from the copyright holder.

PRINTING THE MAP:
It was not possible to fit all U.S. and Canadian area codes into a map size that would print at 100% size on a normal U.S. Letter size page. The best way to print it is to load only the map into your browser or into a GIF-viewing utility, so that you can print it in "Landscape" mode and at a suitable reduction. The map is 800 x 1143 pixels, so a reduction of 50%, or a print setting of at least 125 dots per inch, will allow it to fit easily in a single page. If you click on the map above, it will load into its own window, or you can save it to your hard disk. However, you may not redistribute the map in printed or electronic form without a license. Please do not link directly to the map image from other web sites; link to this page <http://www.LincMad.com/areacodemap.html> only.
