LincMad's New Area Code Dates
Last updated
2017-06-10
Older splits and overlays (effective before 2016‑01‑01) —
see oldnews.html;
Note: all dates are in year-month-day format, so 2017‑04‑26 = April 26, 2017.
Dates given in the form 2017–Q3 are 3rd Quarter of 2017, for example.
For overlays, the first date listed is for mandatory
10‑digit (or in some cases, 1+10‑digit) local calls; if no
date is given, the area already has mandatory 10D/1+10D local calls.
The second date is when numbers in the new overlay code can be assigned.

Note:
323 and 213 are getting a
"boundary elimination overlay,"
similar to the way that area codes 214 and 972 in Dallas were split and
later merged back into an overlay. All existing numbers will remain unchanged,
but 1+10D will be mandatory for all calls. When the combined
213 & 323 area runs out of numbers, a third area code will be
assigned for the same geographic area. |

Mandatory 10-digit dialing will affect
all of western Washington
(area codes 206, 253, and 425,
in addition to 360).
However, new numbers in area code 564 will initially be
assigned only in the 360 area (outside metro Seattle).
As the Seattle metro area codes fill up, they will also
begin assigning 564 numbers.

"10D/1+10D" refers to the date on which it becomes
mandatory to dial all local calls with the area code. In some areas, you
must dial only the area code and number, for a total of 10 digits. In other
areas, you must dial 1 plus the area code and number on all calls. In yet
other areas, you may optionally dial 10D or 1+10D on some or all local calls,
or for calls within your own area code overlay whether the call is local or toll.
If no date is listed in this column, the area already has mandatory 10D/1+10D
local calls, or the listing is for a
non-geographic code
(such as toll-free numbers) in which there are no local calls, as such.
"Overlay" refers to the date on which the new code
goes into effect; that is, the first date on which numbers in the new code
may be assigned and used.
New area codes indicated with a question mark are speculation,
based on available industry data. However, the information should not
be considered reliable until it is officially confirmed by NANPA.
The Test Number is a special number (usually, though not always, not
charged) that allows you to test whether all the links in the chain from you to
a new area code are operating correctly. In order for you to reach a new area
code, your premises equipment (office PBX, for example) must allow you to dial
it. Then the telco central office must accept the new area code as valid and
route it correctly. If the new area code is outside your LATA, your chosen
long-distance carrier must also route the call correctly. Calling one of these
numbers will usually reach a simple recording saying something like, "You
have successfully completed a call to area code XXX."
Note that some test numbers are billable
numbers, possibly at international rates. However, most test numbers in
the U.S. and Canada will not bill. In cases where a test number is shown
ending with –TEST, dial –8378; for –BILL, dial –2455.
Where possible, a test number that is known to
bill is marked with a "$" before the number.
Note that the test number for a new area code is usually disconnected
within a few months after the mandatory date. If you dial one of the older test
numbers shown here, you may reach an ordinary subscriber.
In southern California, two old area code splits will be
erased in a maneuver known as a "boundary elimination
overlay". In downtown Los Angeles, the boundary between
213 and 323 will be eliminated; in San Diego, the boundary
between 619 and 858 will be eliminated. In each case, the
two existing area codes will become an overlay, with numbers
from either code assignable anywhere in the combined geographic
territory.
Area code 870, which covers most of the land area of the
state of Arkansas, was scheduled to have an overlay on
2013‑05‑18, but number conservation measures
extended its life by several years, so the overlay has been
postponed indefinitely. Look for it some time around 2021
or 2022.
The state of Illinois has not yet established effective dates
for the
618/730 (2019?)
and 217/447 (2017?)
overlays, which will be implemented
as the existing codes run low on available numbers.
There have been no area code splits — only overlays —
since 2007‑10‑07, and
no splits are planned. Canada has not had an area code split since
1999‑01‑25; they had
their first overlay on 2001‑03‑25
and haven't looked back.
In fact, Canada has already scheduled overlays in
all but three provinces, all of which will be getting overlays in 2018 or
circa 2019/2020. At that point, the only parts of Canada
Without
overlays will be area code 867 (Yukon, Northwest Territories, and Nunavut)
and area code 807 (northwestern Ontario, including Thunder Bay).
On the chopping block also are local interprovincial 7‑digit
dialing arrangements for Labrador City and Wabush, NL, and for Campbellton, NB,
into the current 418 & 581
(future 418 & 581 & 367)
area of eastern Québec. Those 7‑digit dialing arrangements
will be terminated when Newfoundland & Labrador and New Brunswick
implement mandatory 10‑digit local calls in preparation for their
own overlays.
The Caribbean island of St. Martin is divided between France and the Netherlands.
The Dutch side, known as Sint Maarten, has joined the North American Numbering
Plan as area code 721; Sint Maarten has also been assigned ISO country code SX, and
the corresponding .sx Internet domain is now in use.
The change was originally scheduled for 2010, but was postponed until
2011‑09‑30 (permissive),
2012‑09‑30 (mandatory).
You now must use +1 721;
from North America, dial 1‑721.
All current 7-digit numbers in Sint Maarten begin with '5',
but new numbering ranges will be added in the future.
The French side continues to use +590, or 011‑590 from North America
(including calls from Sint Maarten to French Saint-Martin).
(The French side now has the ISO country code MF,
but .mf is not used for the Internet. Use either .gp (Guadeloupe)
or .fr (France) for French St.‑Martin.)
Het Caribische eiland
Sint Maarten is verdeeld tussen Frankrijk en Nederland.
Het Nederlandse deel heeft zich aangesloten bij de
Noord-Amerikaanse Nummering Plan (+1)
zoals het netnummer 721. De verandering was oorspronkelijk
gepland voor 2010, maar werd uitgesteld.
Permissieve bellen eindigde
2012‑09‑30,
en de nieuwe nummers zijn nu verplicht.
Alle huidige 7-cijferige nummers in Sint Maarten beginnen met '5',
maar nieuwe nummering reeksen kunnen worden toegevoegd.
Gebruikt u de
internationale landcode +1 721;
uit Noord-Amerika, kies 1–721.
Het Franse deel zal blijven +590 te gebruiken,
of 011–590 uit Noord-Amerika.
De andere Nederlandse eilanden in het Caribisch
gebied niet veranderd.
Sint Maarten is toegewezen ISO-landcode SX en de .sx
Internet-domein.
L'île antillaise
de Saint-Martin est divisée entre la France
et les Pays-Bas. La partie néerlandaise, Sint Maarten,
a rejoint le Plan de Numérotation Nord-américain (+1)
avec l'indicatif régional 721 et le domaine de l'Internet .sx
(actuellement en vigueur). Pourtant, la transition a
été remise.
Composition facultative (composer +599 ou +1 721) a commencé
le 2011‑09‑30;
à partir de 2012‑09‑30,
le +1 721 est obligatoire.
Tous les numéros actuels à 7 chiffres à Sint Maarten
commencent par '5', mais d'autres numéros pourraient être ajoutés.
Pendant la période permissive, on pouvait utiliser l'indicatif de pays +599
ou l'indicatif nord-américain +1 721;
en Amérique du Nord, composer le 011–599 ou le 1–721.
Maintenant il faut utiliser seulement +1 721.
La partie française continuera d'utiliser +590,
ou 011–590 d'Amérique du Nord.
Editorial commentary and
explanatory notes about area code splits have now been moved off onto a
separate page.
Don't see a split listed here that used to be? Splits and overlays that have
been cancelled or indefinitely postponed may no longer be shown.
Time Zone information is now available on the
"Locator" page,
which lists all active and upcoming area codes in numeric order with major cities.
There is an excellent listing of
state/provincial regulatory agencies
[link updated 2017‑05‑24]
provided by the state of New York.
