black - new area code is already mandatory (use only the new area code)
blue - new area code in permissive status (use
either old or new)
green - new area code not yet in use (use old area
code until permissive date)
red - special notations
"Permissive" refers to the date at which it becomes possible
to use either the old or the new area code. You should begin using the new
number as soon as possible after the permissive date.
"Mandatory" refers to the date at which it becomes necessary
to use the new area code. If you dial the old area code after the mandatory
date, you will reach an error recording — or worse, a wrong number.
An overlay is
a new area code that occupies the same geographic territory as the existing area
code. Existing numbers are not changed, but new prefixes are assigned from the
new area code.
A realignment
is the assignment of prefixes at the border of one area code to an existing
adjacent area code. Only the indicated area is affected; other numbers in either
area code are unchanged.
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.
The state of Illinois has not yet established effective dates
for the 618/730 and 217/447 overlays, which will be implemented
as the existing codes run low on available numbers. Likewise,
Pennsylvania will implement the 570/272 overlay when 570 runs low
on numbers, probably in late 2012 or early 2013.
The 270/364 split in western Kentucky was postponed several times
and then finally cancelled. As of late 2011, there are no area code
splits pending or planned anywhere in the NANP — only overlays!
Long-dormant overlay plans in Maryland and North Carolina are
finally being implemented, more than 10 years after the overlays
were originally ordered.
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.
The change was originally scheduled for 2010, but was postponed until 2011‑09‑30 (permissive),
2012‑09‑30 (mandatory).
During the permissive period, use either +599 or +1 721;
from North America, dial either 011‑599 or 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.
(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 begon op 2011‑09‑30, en de nieuwe nummers zijn verplicht 2012‑09‑30.
Alle huidige 7-cijferige nummers in Sint Maarten beginnen met '5',
maar nieuwe nummering reeksen kunnen worden toegevoegd.
Tijdens de permissieve periode, gebruikt u de internationale landcode +599 of +1 721;
uit Noord-Amerika, kies 011–599 of 1–721.
Het Franse deel zal blijven +590 te gebruiken,
of 011–590 uit Noord-Amerika.
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 peuvent être ajoutés.
Pendant la période permissive, on peut utiliser l'indicatif de pays +599
ou l'indicatif nord-américain +1 721;
en Amérique du Nord, composez le 011–599 ou le 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
provided by the state of New York.
