Dialing Plan (16 May 1990)

1. Area Codes, North America

Bell Communications Research (Bellcore) is the organisation responsible
for the maintenance of the area codes and the dialing setup for
North America since the breakup of AT&T several years back. This
group sets standards for dialing, telephone number format, etc.

Area codes (or Numbering Plan Areas (NPA)) in North America are presently
of the form NZX where N represents a number from 2 to 8, Z is 0 or 1 and
X is any number. This distinguishes area codes from central office (exchange)
codes which are usually of the form NNX (ie. the difference between an
exchange and an area code is usually in the second digit, whether or not
it is a 0 or 1).

Area codes ending in -11 are not used, as they are normally used for special
services. The special purposes generally reserved are:
       411 directory assistance
       611 repair
       811 business office
       911 emergency

The other N11 codes are sometimes used within specific localities for
special purposes (711 is used for mobile service in British Columbia,
in the form 0+711)). In some cases, services are accessed through the
long distance network (ie. 1+411 or 1+611).

Area codes ending in -10 have been TWX numbers (teletype service).
TWX area codes include 510, 610, 710, 810 and 910. Normal telephone
numbers do not (yet) use area codes ending in -10, though these codes
will be reassigned to regular telephone service as TWX is eliminated.
Upcoming examples of this are the area code splits of 213 (Los Angeles
adds area code 310) and 415 (San Francisco adds area code 510).

Area codes ending in -00 are usually reserved for special services
like 700, 800 or 900. In fact, these codes are not considered to be
area codes as such, but Service Access Codes (SACs).



(2) Dialing Codes...

Theoretical capacity of the telephone system:

The original design of telephone numbers was:
     (NZX) NNX XXXX

In theory, this gives:
     N   Z   X    N   N   X    X    X    X    X
     8 * 2 * 10 * 8 * 8 * 10 * 10 * 10 * 10 * 10 = 1.024 billion numbers

However, as some area codes and exchanges are reserved for special
purposes (such as 411, 555 exchange, etc), the total possible number
of telephone numbers will be somewhat less.

As the exchange codes in some area codes were used up, some central offices
started using the NXX format, where the middle digit can then be a 0 or 1;
examples of these may be found in New York City or Los Angeles. The March
1990 conversion of the (416) area code around Toronto is another example,
as is a similar change to North Carolina's dialing around the same time.
The dialing is changed so that dialing 1+ a number always requires an area
code, and in the case of (416), will mean that 1+416+ will be needed for
long distance calls within (416). In New York City, however, all calls
within an area code are dialed with seven digits only (without dialing
1 first, let alone the area code).

Now, telephone numbers look like this:
     (NZX) NXX XXXX

This gives a potential of:
     N   Z   X    N   X    X    X    X    X    X
     8 * 2 * 10 * 8 * 10 * 10 * 10 * 10 * 10 * 10 = 1.28 billion numbers

However, codes like 411 and 611 would not be assigned because they will
still be needed for services such as directory assistance and repair.
Nevertheless, some unused N11 codes like 211 may be found in some area
codes as active exchanges. It's also not a good idea to assign the home
area code (could cause confusion).

Going from NNX exchange codes to NXX only represents a 25% increase in the
total theoretical amount of telephone numbers, and not all area code regions
are expected to run out of exchanges. Also, area codes do not generally go
outside a state or provincial boundary (the only exceptions are in Canada,
where 902 serves both Nova Scotia and Prince Edward Island, area 819 which
covers the eastern Northwest Territories as well as part of Quebec, and
area 403 which covers Alberta, Yukon and the western Northwest Territories).

The ultimate goal is not only to use area codes for exchanges codes, but
to use exchanges codes for area codes also. This means that telephone
numbers will ultimately look like this:
     (NXX) NXX XXXX

This gives a potential of:
     N   X    X    N   X    X    X    X    X    X
     8 * 10 * 10 * 8 * 10 * 10 * 10 * 10 * 10 * 10 = 6.4 billion numbers

With a five-fold increase in the number of possible area codes, there
should be plenty of room to grow for some time.


(3) Dialing Codes...

Basically, all calls within an area code will ultimately be dialed in
one of the following ways 1) dial seven digits, 2) dial 1 + home area
code + number, or 3) dial 1 + seven digit number within area code, then
wait for a few seconds to time out. One alternative not mentioned in
official documents (for touch tone phones) is to use 1 + seven digit
number in home area code + '#' with the # key terminating the dialing.

The initial set of new area codes will take the form NN0, or those numbers
ending in '0'. This means that areas codes that do not have exchanges
ending in '0' (or only a few NN0 exchanges that could be renumbered)
can still be able to tell the difference between an exchange and an
area code by looking at the first three digits.

The new NN0-type area codes will be assigned starting with these
first few codes (in order):

260, 480, 520, 590, 650, 220, 250, 490, 660, 680, 720, 730, 850, 940 ...

970 will be reserved for phone testing purposes, and is not slated to
become an area code.

All telephone systems are expected to change their systems over to allow
for the new style of area codes by 1 July 1995, or perhaps earlier. This
could mean that other area codes will be required to dial the area code
for long distance calls within area, even though the area code is not
running out of exchanges itself (eg. areas 519, 705).

Dialing Scheme

* 1 + will generally be used for direct-dialed long distance calls within
  North America, especially calls outside the local area code.

* 0 + is used to dial operator-assisted or automated credit card calls within
  North America. After 0 + (area code) + number are dialed, a prompt tone
  (same tones as a dial tone, but for a very short duration) will be issued,
  then one of the following actions will be taken:
      1) wait for a few seconds, then an operator will come on line
      2) dial '0' to get the operator immediately (for a collect, person to
         person call, etc)
      3) dial the telephone company credit card number for billing

  It is unclear what will happen in the cases of automated collect calls,
  as to what kinds of dialing would be standard in that case.


(4) Dialing Codes...

Dialing 0 and waiting will get the local area operator.

* 00 is used in the U.S. to get the operator for a default long distance
  carrier. This is used as most long distance companies have their own
  operators. A single 0 digit will call up the local operator (with the local
  telephone company as opposed to the long distance company).

  It's important to note that the U.S. is broken up into LATAs (Local Access
  Transport Areas), and long distance calls are treated differently whether
  they are made within a LATA, or if a call is placed to another LATA. Thus,
  there could be an operator for within the LATA (intra-LATA calling) and an
  operator for inter-LATA calling (from a long distance carrier).

* 01 is used for overseas calls. 01 + indicates an operator-assisted or 
  automatic credit card call, while 011 + indicates a direct-dialed overseas
  call. 010 is reserved for some unspecified future use.

* 10XXX + is used in the U.S. to indicate which long distance carrier to use
  in a situation known as "equal access". This allows a telephone subscriber
  to select a long distance company for a particular call. For instance,
  10288+ gets AT&T while 10222+ gets MCI and 10333+ US Sprint. After this
  code, a 1 or 0 is dialed (to indicate direct dial or operator-assisted call)
  then the number to be called.

  The codes 10000 is not available for assignment
            10001 - 10099 are reserved for restricted purposes
            10100 - 10199 are reserved for international carriers
                (note that because of possible dialing mistakes that may
                confuse some codes with 01- overseas dialing codes,
                10100-10119 are to be assigned after all 10120-10199 codes
                are assigned.)
            10200 - 10999 are assigned to standard long distance carriers

  A list of the U.S. long distance carriers and their 10XXX+ codes is listed
  in a separate document.

  Canada doesn't have to worry about this code quite yet, depending on the
  results of the CNCP/Rogers intention to provide alternate long distance
  service.

* 11- or '*'- (tone dialing) is reserved for special calling services like
  call waiting functions, etc. For instance, 1170 is used to disable the
  call waiting, like *70 can be used on touch tone phones. The current
  special calling codes on many local telephone systems are:

    *57 or 1157 - call tracing request (some systems use this for call back)
    *60 or 1160 - call blocking activated
    *61 or 1161 - priority ring activated
    *63 or 1163 - select call forwarding activated
    *66 or 1166 - repeat dialing activated
    *67 or 1167 - call number ID blocking (done for each call)
    *69 or 1169 - call return activated
    *70 or 1170 - disable call waiting
    *71 or 1171 - 3 way calling according to usage
    *72 or 1172 - enable call forwarding
    *73 or 1173 - disable call forwarding
    *74 or 1174 - modify speed calling directory entry (for 8 number service)
    *75 or 1175 - modify speed calling directory entry (for 30 number service)
    *76 or 1176 - call pickup
    *79 or 1179 - ring again
    *80 or 1180 - call blocking disabled
    *81 or 1181 - priority ring disabled
    *83 or 1183 - select call forwarding activated
    *86 or 1186 - repeat dialing disabled
    *89 or 1189 - call return disabled


(5) Dialing Codes...

2. Reserved exchanges

Each area code will have certain exchanges set aside for special purposes.
These exchanges are:

555 - directory assistance
950 - used to access other long distance services (U.S.)
958, 959 - reserved for phone tests
976 - special recordings, private services

844 and 936 have been reserved for time and weather services, but this
is not widely adhered to. In area code 416, these exchanges are for
Oakville and Tottenham respectively. These services will likely be
incorporated into 976 service, or into other exchanges.


Other Information

A file with the Tel Docs (TELDOC) package, GUIDECOD.DOC, explains in more
detail the 700, 800 and 900 area codes, with lists of exchange/carrier
assignments and other details. This file should be included in the Tel
Docs package. This is the same document as the Guide prepared by TELECOM
Digest, an electronic conference regarding telephone/telecommunication
matters.

Special Area Codes
600 - Some reports mention that this area code was once reserved for
      special U.S. government purposes.
700 - Special Long Distance services (usually US only)
      Often, a special (700) area number will identify the customer's
      primary long distance carrier in the U.S.: dial 700 555 4141 to
      get the name of the long distance carrier (in some areas of the U.S.)
      700 may be used for other value-added services, according to the
      region and long distance carriers involved.
800 - Toll Free calling (INWATS)
900 - special services (recordings, special promotions, vote tallying,
      usually with toll charge applied)

former TWX (teletypewriter) area code assignments:

410 - Northeastern USA (410 now a Maryland code)
510 - Eastern USA (510 now an Oakland CA code)
610 - Canada
710 - Southern USA (may have been reserved for U.S. government services)
810 - Mexico
910 - Western USA


New Area Codes Format to be Set Up by 1995!!

When all the area codes run out, it is proposed to use NNX codes for area
codes (likely starting July 1995, if not sooner). Codes ending in '0' would
form a new source of area codes (like 220, 850, 990, etc). This would mean
that all long distance calls beginning with 1+ will require area codes,
unless NN0 exchange codes used are avoided within an area code (ie. a method
is devised to distinguish the area codes from the exchanges). As long as no
exchange in an area code ends in '0', the 1 + 7 digit number dialing within
an area code could still be used.

There are extremely few area codes left of the current format: 810
and 910 may be assigned, but that's about it unless some codes of the
form N00 or N11 are assigned, or 610 is removed from Canadian TWX
service. From latest information, July 1995 is still the planned date
that the "interchangeable" area codes are to be permitted on the
telephone network. This date could be pushed back if demand warrants
and approvals are given, however.


The order in which these new area codes are supposed to be assigned is:

260  480  520  590  650  220  250  490  660  680  720  730  850  940
230  240  290  470  550  580  740  930  450  760  880  570  380  460
980  860  960  990  970# 350  540  820  840  690  770  890  320  370
790  280  640  750  270  430  630  670  560  330  340  390  620  830
920  360  440  780  870  420  530

970# - reserved for plant testing exchange/area code
950  - used for long distance carrier access - unknown where it will fit
       in in the ordering of the new NPAs, if it will be assigned at all

             Area Codes - a history of splits and changes


The following is a TELECOM Digest posting from Carl Moore regarding area
code splits and area codes that have gone to NXX prefixes.

X-Telecom-Digest: Volume 11, Issue 975, Message 2 of 8

[Moderator's Note: This is a revised version of an earlier article
which appeared in the Digest under the same name. This article will
also be a file in the Telecom Archives.  PAT]

                         ---------

These areas have N0X/N1X prefixes, which are put in service as an
alternative to splitting an area which has had only NNX up to this
point.  As a result, long distance from these areas is dialed like
this:

  7D or 1+NPA+7D within area (can no longer use 1+7D)
  1+NPA+7D to other areas (can no longer use NPA+7D)
  For all 0+ calls from these areas, try 0+NPA+7D.

I believe these requirements will become universal when area codes
must generalize from N0X/N1X to NXX; deadline for this is July 1995.
But since the first batch of NNX area codes will be of NN0 form, some
areas might be able to keep 1+7D for intra-NPA long distance by
disallowing prefixes of NN0 form; I do not know if this will be
affected by use of 52x codes -- x not necessarily 0 -- for Mexico.  It
is unclear how generalizing area codes to NXX would affect the policy
of not using N0X/N1X prefixes until NNX starts running short.

213, California, July 1973
 (7D on all calls within it)
 (later 213/818, now 213/310/818)
 (this area continued to publish 0+7D instruction for
  within-NPA 0+ calls)

212, New York, some days after 24 Nov 1980
 (7D on all calls within it)
 (now 212/718, to become 212/917/718)

312, Illinois, Oct 1982 -- but got 1st N0X/N1X spring 1983?
 (7D on all calls within it)
 (now 312/708)

201, New Jersey
 (7D on all calls within it; also applies to 609)
 (now 201/908)

214, Texas, 1986 or 1987 (by July 1987)
 (1+NPA+7D on all toll calls; also applies to 817,
  at least in Fort Worth area)

Areacode splits:

Early splits for which no date appears may not have been announced
publicly due to lack of direct-dial facility at the time, and can only
be guessed at with the following guidelines: If an areacode is of form
N1X, it is in a state or province with more than 1 areacode. (The
reverse, if it was ever true, is now obsolete.)  If an areacode is in
a state or province with only 1 areacode, it is of form N0X.  (The
reverse, if it was ever true, is now obsolete.)

    This behaved somewhat like a split despite no new area code.
    202 area code, previously useable for all but the outermost
    Maryland and Virginia suburbs, was restricted to DC proper.
    (Use 301 or 703, as the case may be, to reach the suburbs.)
    As a result, government offices (now including the Pentagon)
    using zipcodes starting with 200,202,203,204,205 and located
    in Md. or Va. can no longer be listed in area 202.  Prefixes
    in the Pentagon, which is in Virginia, were previously in area
    202 (not 703), and in 1990 were moved to area 703.  (Local
    calls across area code border changed from 7D to NPA+7D.)

On Feb 1, 1991, area codes 706 and 905, which had been used in the
U.S. for calling parts of Mexico, were discontinued and thus became
available for use elsewhere.  Country code 52 is to be used for calls
to Mexico.

Country Codes   20 December 1991

International dialing uses country codes from 1 to 3 digits. These are
grouped (usually) according to geographic location. Not all countries can
dial direct to all other overseas codes, but these are the codes by which
a country's telephone network is recognised.

When listing a telephone number in international correspondence, one format
often used lists the country code followed by the area code and local number
digits required to complete the call. For instance, the number (400) 012.3456
in North America would be listed as "+ 1 400 012 3456". The overseas dialing
code would be used then the digits after the "+".

Example: "+44 71 967 1111" would be dialed from North America as
011 + 44 71 967 1111.

Codes marked with '%' mean that this is a country not dialable from
Canada as of March 1990.

Notes:

Mexico locations with former Zone 1 style area codes (706, 903, 905)
are generally out of service by now. This was only a rigged-up system
to allow dialing to Mexico City and Northwest Mexico from U.S. or Canadian
phones. These are not official (were in use within the U.S. and Canada
*only*) and are now replaced with the overseas dialing system (country code 52).

[1] Trinidad and Tobago has been assigned code 296. The date when this
    country code will take effect is unknown.

    country code 259 is assigned for Zanzibar.
[3] St Helena is a code found in service under British Telecom.
    It may not be an official assignment much as it would be a
    hack used by BT to provide overseas service to that point.
[4] San Marino will be split from Italy's country code (was 39).
[5] Trinidad and Tobago are new with country code 296, moving out of
    North American area code 809 (ie. + 1 809). The date when this
    country code takes effect is unknown.
[6] Aruba got its own country code when it formally became independent
    of the Netherlands Antilles 1st January 1986.

[8] Greenland (country code 299) is supposed to be in the part of the world
    where country codes begin with 3 or 4 (Europe). However, since all those
    codes are used up, 299 is as close to 3 or 4 as possible. Country codes
    beginning with 5 are also all gone.

Unknown or unused, but reserved for Maritime Mobile service:
                   870, 875, 876, 877

Notes:

[19] 874 is a new assignment as INMARSAT is putting a fourth satellite
     into service, and adjusting its zones accordingly. This is to
     allow for new land-based services on the INMARSAT network, particularly
     in North America. 874 will become Atlantic Ocean Region West, while
     871 will be for Atlantic Ocean Region East.
[20] Reserved for national mobile/maritime uses in various countries
[21] By CCITT policy, no more country codes of the 880-889 series are
     supposed to be assigned until all other country codes beginning
     with 8 have been taken. 886 for Taiwan is an unofficial code used
     for access to Taiwan. The "People's" Republic of China, on the
     other hand, has assigned Taiwan access via country code 866
     (presumably + 86 6, through China).
[22] There is some discussion in CCITT circles that the 800 country
     code could be established as an international-access toll free
     service. This is subject to a formal proposal and CCITT approval,
     however.

Notes:

[23] with the unification of the Yemen republics, it appears that this
     country code will no longer be needed, as 967 Yemen Arab Republic
     code will likely take over. In the meantime, the dialing procedures
     remain as if Yemen were still separate countries, at least until
     the telephone system can be unified.

No country codes begin with '0'.

(6) Country Codes...

There would be 197 assigned country codes, with 8 codes reserved (210, 211,
214, 215, 217, 219, 878, 879). 77 more standard country codes can be assigned
(assuming that 2 digit codes aren't split up into 3 digit codes, etc), not
including the 4 unassigned/unknown mobile/marisat codes in the 87x series.

Approximately 21 country codes are not dialable from Canada as of
December 1991 (including any country codes yet to be placed into service
like Trinidad & Tobago). The most recent to be in service from Canada
are 224 Guinea, 231 Liberia and 232 Sierra Leone. 355 Albania was recently
made available for dialing, the result of reforms in that country. Romania
(40) seemed to have been active for some time, but is presently
unavailable as a dialable country. Also recently added were 233 Ghana,
253 Djibouti, 258 Mozambique, 264 Namibia, and 95 Myanmar (Burma).
There are signs that 296 Trinidad and Tobago may be placed into service
soon from Canada. From a payphone, it cost $16.30 (in March 1991) for
a 3-minute call to Myanmar/Burma from Canada. Ghana is a relative
bargain at $7.95 for 3 minutes. Don't even think of trying to use
coins for an Inmarsat call ($36 or more for the three minutes).

Thanks go to those who discussed the country codes on Telecom Digest,
a service avaialable through Usenet and other places. In particular,
information from John Covert, Mike Grant, Dolf Grunbauer, John Levine,
Chris Johnston and undoubtedly others of this newsgroup has been helpful
in the updating of this list.
