Now with Time Zones!

The map now shows time zones! From the second Sunday in March until the first Sunday in November each year — for example, from 2013‑03‑10 to 2013‑11‑03 — most areas observe Daylight Saving Time, moving clocks forward one hour. The clock for each time zone indicates Standard Time first and then Daylight Saving Time. However, some areas do not observe DST: Hawaii, Arizona (except the Navajo Nation), part of British Columbia, most of Saskatchewan, small parts of Ontario and Québec, Puerto Rico, and the U.S. Virgin Islands. These areas observe Standard Time year-round, and so are displayed with only one time on the clock. (Note that the entire state of Indiana now does observe DST.) Note also that the Aleutian Islands in extreme southwestern Alaska are in the Hawaii-Aleutian Time Zone (2:00•3:00), and a small portion of Nunavut in northern Canada is in Eastern Standard Time year-round (7:00). To convert to international notation, subtract 12 hours from the time indicated on the map; for example, Pacific Time is shown as 4:00•5:00, corresponding to UTC–08:00 in winter and UTC–07:00 in summer.

The "Locator" page (en français, en español) lists the principal time zone and major cities for each area code, and is also the quickest way to answer the question "Where is area code ###?"

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; the 236 overlay code will be added province-wide on 2013‑06‑01. Area code 306, which serves the entire province of Saskatchewan, was overlaid with a new area code, 639, on 2013‑05‑25. On 2013‑03‑25, the Toronto area received two new overlay codes. The city of Toronto added 437 to 416 & 647; the suburbs added 365 to 905 & 289. Several other areas that approved overlays about a decade ago but then postponed them due to number conservation efforts or other factors, are finally bringing those overlays into effect in the next couple of years. Baltimore, Maryland's 401 & 443 added 667 — originally planned for 2001 — effective 2012‑03‑24. Raleigh, North Carolina's 919 finally got its 984 overlay code, originally planned for 2002, effective 2012‑04‑30. San José, California's 408 & 669 overlay went into effect 2012‑11‑20. Austin, Texas' 512 & 737 overlay goes into effect 2013‑07‑01. Northern and eastern Connecticut's 860 & 959 overlay is expected to finally go into effect some time in 2013 or 2014. In the table below, "Dom. Rep." is the Dominican Republic. The states are slightly out of alphabetical order to avoid breaking a state across two columns. (For more detailed information about current and future overlays, see the overlays.html page. For other area code information, check the main page.)

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 2013‑06‑03 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 may no longer be shown. Check the separate page for information about the 19-way split in the Caribbean area. There is also a Caribbean map, which also now shows time zones. Some of the area codes shown above may not yet be in use. For information on the split dates of new area codes, see the table on the separate page. All boundaries shown are approximate.

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, until recently part of the Netherlands Antilles. However, Sint Maarten has politically separated from the rest of the Netherlands Antilles, although it remains a part of the Kingdom of the Netherlands. Along with the political change, Sint Maarten also changed from the old 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 did not affect French Saint-Martin (+590) nor the rest of the Netherlands Antilles (+599 and +297). The 7-digit number in Sint Maarten will remain the same; all existing numbers begin with '5'. The telephone code change was originally planned for 2010‑05‑31, but was postponed until 2011‑09‑30, with permissive dialing until 2012‑09‑30. Use of the new North American area code +1 721 is now mandatory. Sint Maarten's new Internet domain, .sx, is now active. (informatie in het Nederlands • renseignements en français)
  
  
• Area code 920, serving northeastern Wisconsin including Green Bay, was scheduled for an overlay in 2014, but number conservation measures have allowed the overlay to be postponed indefinitely (probably until about 2016 or 2017).
  
  
• Area code 870, serving most of Arkansas, was scheduled for an overlay in 2013, but number conservation measures have allowed the overlay to be postponed indefinitely (probably until about 2018 or 2019).
  
  
• Area code 270 in Kentucky was planned for a geographic split, with the westernmost part of the state changing to area code 364, but the split was repeatedly postponed and finally cancelled — but then brought back as an overlay for 2014!
  
  
• Area code 814 in western Pennsylvania was set for a geographic split some time in 2012 or 2013. However, number conservation efforts have given 814 some breathing room. As a result, the split has been postponed, and the PPUC is reopening the question of split or overlay.
  
  
• The small town of Hyder, Alaska, is served by the telephone system in adjacent Stewart, B.C., Canada, in area code 250. Calls to Hyder from other parts of the U.S., including other parts of Alaska, are billed at the international rates for Canada.
  
  
• The entire state of Nevada is in the Pacific Time Zone (4:00 • 5:00), with the exception of the town of West Wendover, which is in Mountain Time (5:00 • 6:00) to match neighboring Wendover, UT. However, several other Nevada towns near the Utah or Idaho border unofficially observe Mountain Time.
  
  
• 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.
  
  
• After numerous postponements, Utah 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 is still 442, but existing numbers in 760 did 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 been 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. Area code 408 (San José) got the first overlay in northern California, with the 408 & 669 overlay effective 2012‑11‑20.
  
  
• 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 & 458.
  
  
• 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 2013 or 2014.
  
  
• Just in time for Halloween, news that several "zombie" overlays — overlay area codes that were approved about a decade ago but then postponed indefinitely — are being brought back to life! The overlays of 408 in California and 860 in Connecticut are noted above; Maryland's 410, North Carolina's 919, Texas' 512, and Illinois' 708 are also likely to join the overlay club soon. The 708 area code is the only remaining non-overlay area in northern Illinois.
  
  
• 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. Calls from the US mainland to these locations should be billed as domestic calls, but may or may not be included in "nationwide" calling plans. 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.

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 graphics program, so that you can print it in "Landscape" mode and at a suitable reduction. The map is 1174 x 1624 pixels, so a reduction of 45%, or a print setting of at least 150 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.
