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 alpha 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)

In Illinois, area code 779 overlaid area code 815 on 2007-03-17, and area code 331 overlaid area code 630 on 2007-10-07; activation dates for the other two new overlays in the state have not yet been announced. The concentrated overlay in northwestern Oregon converted to an ordinary overlay on 2007-10-21; i.e., both the Portland/Salem metropolitan areas and the coastal area around Astoria are now served by both area codes 503 and 971, with mandatory 10-digit dialing for all local calls. The concentrated overlay in southern British Columbia converted to an ordinary overlay on 2007-07-04, although 10-digit dialing is not mandatory in the 250 area until 2008-09-12. The only remaining concentrated overlay is in Orlando, Florida, with its mutant hybrid "double back somersault reverse concentrated overlay with a twist."

This map shows all telephone area codes in use as of 2008-11-29 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

ERRATA, UPDATES and NOTES:

• 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 state of West Virginia will get an overlay, with the new 681 area code covering the entire state, effective 2009-03-28.
  
  
• The western tip of Kentucky has an area code split scheduled for 2010-04-01, with mandatory use a few months later. The split has already been postponed three times, but is on track for April Fools Day, 2010. However, since that date falls on a Thursday and permissive dialing almost always begins on a weekend, don't be surprised if the date gets shifted yet 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 scheduled the 801/385 overlay — originally slated as a split on 2000-12-31! — to take effect 2009-03-29.
  
  
• 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, effective 2009-11-21. 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. Two additional overlays will be added in southern California: 714 in northern Orange County added the 657 overlay code on 2008-09-23, and 818 in Burbank and the San Fernando Valley area will add the 747 overlay code on 2009-05-18, 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.
  
  
• Canada implemented two overlays in late 2006. Southern Ontario, including London and Windsor, is now 519 & 226; Montréal is now 514 & 438. The 778 overlay code in British Columbia has expanded to cover the entire province (area codes 604 and 250). Similarly, the new 587 overlay code now covers the entire province of Alberta (area codes 403 and 780), effective 2008-09-19. Also on 2008-09-19, the 581 area code overlaid 418 in eastern Québec (Québec city, Gaspé). Ottawa's area code 613 will be overlaid with 343 on 2010-09-18.
  
  
• New Mexico has had its first area code split, permissive on 2007-10-07, mandatory on 2008-10-05. Albuquerque, Santa Fe, Las Vegas, and Farmington remained in 505; Las Cruces, Roswell, and Taos changed to 575.
  
  
• Illinois has four new overlays. The 815 area in northwestern Illinois (Rockford) was overlaid with 779 on 2007-03-17, and the 630 area in the western suburbs of Chicago (Aurora, Hinsdale); the other two overlays will be activated when the existing prefixes are all assigned. Expect 618 & 730 and 217 & 447 in 2009.
  
  
• 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, it now appears that they will take place in 2010 or 2011.
  
  
• 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.
