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
2022-03-13
to
2022-11-06 ,
and from
2023-03-12
to 2023-11-05
— 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),
Yukon, part of British Columbia, most of Saskatchewan,
small parts of Ontario and Québec,
Puerto Rico, the U.S. Virgin Islands, Guam, and the CNMI.
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 only concentrated overlays, in Florida, Oregon and British Columbia,
have been “unconcentrated,” expanding to cover the entirety of the
original area codes.
Area code 870 in Arkansas was planned for an overlay with 327,
but the overlay has been postponed until
2024-06-04
.
Several other areas that approved overlays about a decade ago
but then postponed them due to number conservation efforts or
other factors, have finally brought those overlays into effect.
In the table below,
“Dom. Rep.”
is the Dominican Republic
(la República Dominicana)
.
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 .)

Errata, Updates and
Notes:
Arizona has decided to implement a double
boundary elimination overlay, converting the 602/480/623 3‑way split
into the 602 & 480 & 623
overlay, effective
2023-09-12 . In theory, any of those three area codes could be used
anywhere in the Phoenix metro area, but in practice, only 623 has a large number
of unused prefixes, so most if not all 602 and 480 numbers will continue to be
located in their respective geographic zones, but 623 numbers will be assigned
throughout all three zones.
Big 10D: In 2021 and 2022, most U.S. area codes
that don’t already have overlays,
will implement mandatory 10‑digit dialing
anyway due to a new federal mandate. For more information, see
“The Big 10D .”
Those areas are not indicated on this map.
Yukon changed to year-round
Mountain Standard Time
(5:00 in LincMad notation, UTC–07:00 ) effective
2020-03-08 .
Since Yukon had been in the
Pacific Time Zone,
the effect is the same as remaining permanently on
Pacific Daylight Time.
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.
(For more information, see the note below .)
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!
California implemented two
“boundary elimination overlays ”,
which means that two adjacent area codes combine and
intermingle into a single overlay area.
In Los Angeles, area codes 213 and 323 merged on
2017-08-01 ;
in San Diego, area codes 619 and 858 merged on
2018-06-19 .
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 & 321 .
The Orlando area again ran short of numbers, so on
2019-06-04
area code 689 was added as a further overlay of the
407 & 321 area, although,
at least for the time being, 321 will continue also to be
the non‑overlay code for the Space Coast.
However, the “Space Coast” area will be changing to
mandatory 10‑digit dialing anyway, due to
“The Big 10D .”
‡
Overlay area code 564 in western
Washington state
currently covers only area code 360.
However, 564 will also be used to overlay area codes
206, 253, and 425 as they run out of numbers.
Thus, 564 will eventually overlay all of the
western part of Washington state.Illinois has three planned area code overlays
that have been on “real soon now” status for years, waiting to be
launched on very short notice when the existing area code reaches
a certain trigger point as it runs low on numbers.
The overlay of area code 217 has finally
happened , effective
2021-03-27 .
The overlay of area code 708 was originally approved
in June 1999, with implementation details approved in July 2021.
The 708 & 464
overlay finally took effect on
2022-01-21 ;
the 618 & 730
overlay is now scheduled for the summer of 2023.
The Canadian province of Newfoundland and Labrador
(Terre-Neuve-et-Labrador)
is planning to overlay its area code 709
with the new code 879. The overlay was scheduled for
2018-11-24 ,
but it was postponed several times and ultimately suspended,
probably until about 2026.
Jamaica implemented an overlay
2019-04-30 .
Existing area code 876 was overlaid with new area code 658.
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 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 & +297) .
The 7-digit number in Sint Maarten remained 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 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.

Area code 920, serving northeastern Wisconsin
including Green Bay, was originally scheduled for an overlay in 2012,
but number conservation measures have allowed the overlay
to be postponed significantly. The overlay has finally was officially
scheduled for 2024-03-22 , but has
been advanced to 2023-05-05&larm;
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 2024).
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 in 2014!
Area code 814 in western Pennsylvania was set
for a geographic split some time in 2012 or 2013.
However, number conservation efforts gave 814 some breathing room.
As a result, the split was postponed, and the PPUC decided on an
overlay of 814 & 582 , effective
2021-05-01 .
The entire state of Pennsylvania now has overlays.
The small town of Hyder, Alaska , is served by
the telephone system in adjacent Stewart, B.C., Canada, in
area codes 250 and 778 (but so far not area codes 236 or 672).
Calls to Hyder from other parts of the U.S., including other
parts of Alaska, are billed at the international rates for Canada.
Conversely, calls between Hyder and any point in Canada are
billed as Canadian domestic calls.
The even smaller settlement of Estcourt Station, Maine ,
the very northernmost point in New England, is served by the telephone system
in neighbo(u)ring Pohénégamook, Québec, using area code 418. Just as in
Hyder, calls to Estcourt Station, from whatever location,
are billed as calls to 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 officially in Mountain
Time
(5:00 • 6:00)
to match neighboring Wendover, UT.
However, several other Nevada towns and rural areas near the
Utah or Idaho border unofficially observe Mountain Time.
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),
an island nation north of Australia.
