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 2014‑03‑09 to 2014‑11‑02 — 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.

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 was added province-wide
Area code 306, which serves the entire province of Saskatchewan, was
overlaid with a new area code, 639,
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.
Area code 870 in Arkansas was planned for an overlay with 327, but the overlay
has been indefinitely postponed, probably until about 2018.
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 —
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 went into effect
Northern and eastern Connecticut's 860 & 959 overlay
is expected to finally go into effect some time in 2014.
In the table below,
is the Dominican Republic (la República Dominicana).
The states are slightly out of alphabetical order to avoid breaking a state
across two columns.

Errata, Updates and Notes:
- The last time there was an area code split in the NANP was New Mexico
on 2007‑10‑07. The last split in Canada was Alberta on
1999‑01‑25. Since then, it's been all overlays!
- Also not shown on the map are three U.S. territories in the Pacific:
Guam 671, American Samoa 684, and the
Commonwealth of the Northern Mariana Islands 670.
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
- 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
- Area code 760 in southern California was scheduled to split
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 have retained 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
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
- The northwestern corner of Oregon, including
Portland, Salem, and Astoria, is served by the
503 & 971 overlay.
The rest of Oregon is area codes
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.
- 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
has been recycled for Timor-Leste (East Timor).
- Area code 407 in Florida performed a
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 & 321.

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
