WA: western half of the state, including Seattle,
Olympia, Vancouver (OVERLAY of multiple codes) (was originally to be overlay only of 360)
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 of the test
numbers for the new Caribbean area codes are billable numbers, at international rates. However,
most test numbers in the U.S. and Canada will not bill. Where
possible, a test number that is known to
bill is marked with a "$" before the number. Note that several
of the test numbers for California were changed from the originally announced
number; the changed numbers are indicated in red above.
Note also 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.
Don't see a split listed here that used to be? Postponed splits and overlays
have been moved onto a separate page. There are now postponed relief plans in
CA, IL, MI, TX, MD, CT, NM, and.
