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. Likewise, concentrated overlays are no longer indicated on the map. In the table below, "Dom. Rep." is the Dominican Republic; Ohio is listed out of sequence for spacing reasons.

Table Notations:
% concentrated overlay (new area code covers only part of old)
( ) 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)

Area code 815 in Illinois will overlay on 2007-03-17; activation dates for the other three new overlays in the state have not yet been announced. The concentrated overlay in northwestern Oregon will convert to an ordinary overlay on 2007-10-21; i.e., both the Portland/Salem metropolitan areas and the coastal area around Astoria will be served by both area codes 503 and 971, with mandatory 10-digit dialing for all local calls. (The concentrated overlay in Miami and the Florida Keys has already converted to an ordinary overlay, which will leave only Vancouver, Canada, and Orlando, Florida, with concentrated overlays.)

This map shows all telephone area codes in use as of 2007-02-22 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	441	Bermuda	784	St. Vincent & the Grenadines
246	Barbados	473	Grenada	809 829	Dominican Republic
264	Anguilla	649	Turks & Caicos
268	Antigua & Barbuda	664	Montserrat	868	Trinidad & Tobago
284	British Virgin Islands	758	St. Lucia	869	St. Kitts & Nevis
345	Cayman Islands	767	Dominica	876	Jamaica

ERRATA, UPDATES and NOTES:

• New Mexico will have its first area code split, permissive on 2007-10-07, mandatory on 2008-10-05. Albuquerque, Santa Fe, Las Vegas, and Farmington will remain in 505; Las Cruces, Roswell, and Taos will change to 575.
• Illinois has four new overlays on the way. The 815 area in northwestern Illinois (Rockford) will overlay with 779 on 2007-03-17; the other three overlays will be activated when the existing prefixes are all assigned. Expect 618 & 730 and 630 & 331 in the spring of 2007, and 217 & 447 in late 2007 or early 2008.
• Canada implemented two overlays in late 2006. Southern Ontario, including London and Windsor, is now 519 & 226; Montréal is now 514 & 438.
• 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.
• 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.
• American Samoa, a U.S. territory in the South Pacific, including Pago Pago, is now area code 684, replacing its former international country code +684, effective 2004-10-02, mandatory since 2005-04-02. For callers in the rest of the NANP, 011-684 changed to 1-684; for the rest of the world, +684 changed to +1-684. All calls to AS American Samoa must now use the new NANP area code; calls to country code +684 will not complete. Nearby WS Independent (Western) Samoa, country code +685, is not affected by this change.
• 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.
