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
— 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.

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 indefinitely postponed,
probably until about 2024.
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,
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.

Errata, Updates and
- 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
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
The last split in Canada was Alberta on
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
in San Diego, area codes 619 and 858 merged on
- Area code 407 in Florida performed a
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
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
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
The overlay of area code 708 was approved in June 1999, with
implementation details approved in July 2021.
The 708 & 464
overlay will take effect on 2022-01-21;
the 618 & 730
overlay probably will not happen until the year 2025!
- The Canadian province of Newfoundland and Labrador
is planning to overlay its area code 709
with the new code 879. The overlay was scheduled for
but it was postponed several times and ultimately suspended,
probably until about 2026.
- Jamaica implemented an overlay
Existing area code 876 was overlaid with new area code 658.
- The island of Saint Martin in the Caribbean

The north side is the French overseas collectivity of Saint-Martin;
the south side is the Dutch municipality of
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
as dialed from North America) to the
North American area code 721
for the rest of the world).
This change did not affect French Saint-Martin
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
with permissive dialing until 2012-09-30.
Use of the new North American area code
is now mandatory.
Sint Maarten’s new Internet domain,
.sx, is now active.

- 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
- 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 code 250 (but not area codes 604, 778, 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 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
(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
(i.e., dial 011–685).
Furthermore, the CNMI’s old country code +670
has been recycled for Timor Leste (East Timor),
an island nation north of Australia.

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 to fit on one page.
If you click on the map above, it will load into its own window,
or you can save it to your hard disk.
