5 September 2000 - Canadian Switched Network (CSN) area code 319
The Canadian Switched Network (CSN) is operated by Canada's
for
its telecommunications needs. It is interconnected with the U.S.-based
DSN and is effectively part of its numbering plan.
As of 5 September 2000, area code 319 was in service for CSN numbers.
Previously, Canadian points had been part of DSN area code 312, until
numbering growth had prompted a need for area code 312 relief.

Global Mobile Satellite System (GMSS) |
+881 |
assigned country code +881 for
Global Mobile Satellite System (GMSS).
This code is shared among providers of global satellite telecom services
such as Ellipso,
Iridium,
etc.
Some of the satellite services had serious financial difficulties early in
their operations, but Ellipso,
and
Iridium services
remained in operation as of 2003.
GMSS events
1 June 2003: +881 3 dialling activated for Ellipso system. Initial
subscriber numbers have 5-digit length, thus the dialling format
is +881 3 xxxxx. Following initial launch of service, a 3-digit area
code may be introduced in the future to define type of service and country
location. Routing of calls for initial service is through KPN Telecom B.V.
in the Netherlands.
(Source:
Ellipso announcement via ITU, 2003)
14 March 2001: ICO-Teledesic and
Ellipso announced a
merger of
their respective satellite mobile systems. There was no immediate
word on what changes would occur to the GMSS numbering assignments.
17 December 1997: Odyssey system was cancelled in favour of ICO's
service. Its GMSS numbering range was presumably re-assigned to
Ellipso.
Iridium: The first global mobile satellite service was Iridium. This
began service with numbers in the +881 6 range. +881 7 Iridium
number range was reserved. The Iridium service ran into bankruptcy problems
and was originally expected to be discontinued in early 2000. But another
party purchased the assets at a fraction of the development price and
continued the service. As of 2003, Iridium appeared to have continued
success, particularly with satellite phone demands for the early 2003
U.S.-Iraq war.
GMSS number range assignments
Since various satellite carriers share this country code,
the ITU allocates the first digit that follows the +881 country code
to satellite carriers as follows:
+881 0 ICO Global Communications (reserved) +881 1 ICO Global Communications (reserved) +881 2 vacant (formerly Ellipso, Odyssey; assigned 29 June 2000) +881 3 vacant (formerly Ellipso, Odyssey; assigned 29 June 2000) +881 4 spare for future service +881 5 spare for future service +881 6 Iridium (assigned 10 November 1997) +881 7 Iridium (assigned 10 November 1997) +881 8 Globalstar (assigned 24 February 1999) +881 9 Globalstar (assigned 24 February 1999)
The Ellipso assignments, +881 2 and +881 3, were vacated effective
2 June 2008
(
ITU-T SG2 NCT: E.164 country code 881 plus two 1-digit ICs.)

Inmarsat |
+870 to +874 |
is a satellite-based
telecommunications system. It is primarily designed for ships at sea,
but can be used throughout most of the world where conventional telephone
services are not yet available or feasible (such as low-population islands
or remote locations).
According to an ATIS presentation,
satellite maritime service for American navy and other customers was
established as Marisat in 1976. In 1979, Inmarsat was established as
an intergovernmental treaty organization (IGO), then privatised as a
UK limited company in 1999.
Country code assignments for the Inmarsat maritime/mobile service:
+870 - Single Number Access (SNAC) service - assigned late 1995
+871 - Atlantic Ocean East [note 1]
+872 - Pacific Ocean
+873 - Indian Ocean
+874 - Atlantic Ocean West [note 1]
[note 1] - country code +871 was originally assigned for the entire Atlantic
Ocean Region until the territory was split by a new +874 country code at
a date unknown to WTNG. This was due to a new Inmarsat satellite entering
service for the Atlantic ocean region. One reference indicates +874 took
effect in 1995.
The choice of country code from +871 through +874 is determined by the
region in which an Inmarsat terminal is located. The subscriber number of
an Inmarsat terminal will be unique in the world, meaning that the same
number should not be duplicated in different Inmarsat region country codes.
The +870 single number access country code will eventually replace the
separate region country codes.
Inmarsat Service Types
Some notable types of Inmarsat service:
-
A: Inmarsat-A is the original analogue system, with capacity for
data transmission from 9.6 to 64 kb/s. It is accessible by regular
telephone networks on the regional country codes +871 through +874 -
B: Inmarsat-B is a digital successor to Inmarsat-A which is more
efficient with satellite capacity. Data transmission from 9.6
to 64 kb/s is supported. It is accessible by regular
telephone networks as with Inmarsat-A. -
BGAN: Broadband Global Area Network (BGAN) is a single network concept
that is due to begin service in late-2005. It will be reachable from
regular telephone networks using country code +870 (the regional
satellite codes will not be used for BGAN). -
C: Inmarsat-C is used for low-bandwidth packet data uses, such as maritime
distress (GMDSS). Inmarsat-C numbers are designed for data transmission
of about 600 bits/second. These numbers do not support voice and
are not accessible from regular telephone networks. -
Fleet: Inmarsat Fleet service is a digital multi-functional service.
Newer offerings in this range are designed for use with smaller vessels. -
GAN: Global Area Network - supports such activities as
corporate data networks, broadcasting. -
M: Inmarsat-M is a digital service, providing 2.4 kb/s data transmission
with medium-sized antennas. -
Mini-M: This is a digital service for voice and data of up to 9.6 kb/s
(compressed, 2.4 kb/s uncompressed). -
Regional BGAN: Supports 144 kb/s shared data channel in Europe,
north and central Africa, Middle East, much of Asia. - Swift64: 64 kb/s ISDN-grade digital aeronautical service.
Basic subscriber number formats
Inmarsat Mobile Number (IMN) is the basic subscriber number for
Inmarsat. This represents a "ship ID", although Inmarsat users
may also be based on land. Some IMNs are only accessible through
the newer +870 country code (common access). Other numbers may
be reached through one of the regional codes (+871 through +874).
Initial digits of IMN represent the type of Inmarsat service:
Numbering Inmarsat Service Comments ========= ================ ======== 0... reserved 1iiixxxx A discontinued by end-2007? 2... reserved 3mmmxxxxx B / Maritime normal phone, fax, 9.6 kb/s data 38nnnxxxx B / Land normal phone, fax, 9.6 kb/s data 39dxxxxxx B-HSD ISDN access 4mmmxxxxx C / Maritime data communications $ 49nnnxxxx C / Land $ 5oooooooo Aero based on ICAO technical address 6mmmxxxxx M / Maritime normal phone, fax data 60xxxxxxx F (Fleet) HSD/ISDN access; Fleet77, GAN, Swift 64 60xxxxxxx M4-HSD HSD/ISDN access 68nnnxxxxx M / Land normal phone, fax, data 70xxxxxxx reserved for future 71xxxxxxx reserved for future 72xxxxxxx reserved for future 73xxxxxxx reserved for future 74xxxxxxx reserved for future 75xxxxxxx reserved for future 76xxxxxxx F (Fleet77), GAN 76xxxxxxx Mini-M and M4 77xxxxxxx BGAN in service end-2005 78xxxxxxx BGAN format not finalised as of early 2005 79xxxxxxx reserved for future 8yxxxxxxx channel selection used with Inmarsat A 9... special call routing as allocated by ITU-T Legend for digits ----------------- d = D digit (data) iii = MID digits - identifying country of origin (defined by Inmarsat) mmm = MID digits - identifying country of origin (defined by ITU-R) nnn = LID digits - identifying country of origin o = octal digit (0 to 7; 8 and 9 invalid) x = any digit y = application-specific digit
One source indicated 811xxxxxx subscriber number range was for indicating
fax calls i.e. prefix '81' to an Inmarsat-A subscriber number.
+870 active number ranges
Numbering ranges for +870 (common access) always use 9-digit
subscriber numbers. Certain services such as Aeronautical and
Inmarsat-C are not reachable from regular telephone networks.
The following subscriber number ranges are in effect for +870:
Range Service/Allocation ===== ================== 0xxxxxxxx reserved (used in Inmarsat-A in +871 to +874) 1xxxxxxxx reserved (used in Inmarsat-A in +871 to +874) 2xxxxxxxx reserved for future 3xxxxxxxx B / Maritime - ordinary calls (except for ranges below) 38xxxxxxx B / Land - ordinary calls 39xxxxxxx B / Land and Maritime - high-speed data 40xxxxxxx C / Maritime - ordinary calls/messaging (except for ranges below) 48xxxxxxx C / reserved for future 49xxxxxxx C / Land - ordinary calls (messaging) 5xxxxxxxx Aeronautical / primary address (except for ranges below) 58xxxxxxx Aeronautical system/Alternate address 59xxxxxxx Aeronautical system/Special facilities 60xxxxxxx Fleet, GAN, Swift 64/Maritime mobile - ISDN calls 61xxxxxxx M / Maritime - ordinary calls 62xxxxxxx M / Maritime - ordinary calls 63xxxxxxx M / Maritime - ordinary calls 64xxxxxxx M / Maritime - ordinary calls 65xxxxxxx M / Maritime - ordinary calls 66xxxxxxx M / Maritime - ordinary calls 67xxxxxxx M / Maritime - ordinary calls 68xxxxxxx M / Land - ordinary calls 69xxxxxxx M / Land - ordinary calls 7xxxxxxxx reserved for future (except for ranges below) 76xxxxxxx Mini-M, GAN, Fleet/ordinary calls - Maritime or Land 77xxxxxxx BGAN - ordinary calls 78xxxxxxx BGAN - CS data (B-ISDN, 64 kb/s UDI); secure voice (including fax) 79xxxxxxx reserved for future 8xxxxxxxx reserved (range used in Inmarsat-A in +871 to +874) 9xxxxxxxx reserved for entry routing node identification
+871, +872, +873, +874 active number ranges

by 31 December 2009 - consolidation of country codes to +870
The +870 Single Number Access (SNAC) code will replace the individual
regional country codes +871 through +874. ITU-T Recommendation E.215,
chapter 3 describes this service.
Carrier Telenor indicates that SNAC is in use for Inmarsat GAN,
Inmarsat Mini-M (Mobiq), Inmarsat-M and Inmarsat-B services.
Inmarsat-A still requires the separate regional country codes.
A target date of 1 July 2015 was initially reported for this consolidation.
However, an
indicated
the consolidation would complete by the end of 2009.
New Inmarsat services are to be offered on +870, rather than on
the regional country codes from +871 to +874.
A separate report suggested ITU earlier proposed a 1 January 2009
deadline for consolidation, advanced from the original 2015 target.

31 December 2007 - Inmarsat-A service discontinued
will decommission its
Inmarsat A service as of 31 December 2007 in favour of newer digital
services. Current users would be expected to convert to such newer
digital services as Inmarsat Fleet F77. Inmarsat A has been in service
since 1982.

1 November 2005 - BGAN numbers introduced
Inmarsat activated BGAN
(Broadband Global Area Network) service in late-2005 (previously
scheduled mid-2004).
Numbers in this service are under country code +870,
with initial 9-digit subscriber numbers beginning with 77 and 78
(that is, +870 77xxxxxxx or +870 78xxxxxxx format).
The initial announcement for this expansion only indicated new numbers

International Freephone Service (UIFN) |
+800 |
The ITU has established a process leading to the first assignments of international
"freephone" numbers. Callers in certain countries can now use special country
code +800 to make international toll-free calls via existing international
dialling methods. Such international numbers are not yet widely known,
however.
The International Freephone numbers are apparently 8 digits length
following the country code +800. Effective with Time 'T',
a maximum 12 digits following +800 are available for number expansion.
See
Freephone (UIFN) service
.
Some international freephone information may be available via
ICB Toll Free.

recently +883 for "International Networks" to be shared among various
carriers.
+882 assignments
For +882, the carrier is identified according to the two digits
following the country code.

International Premium Rate Service (IPRS) |
+979 |
A system for international calling for premium services, or International
Premium Rate Service (IPRS), was defined in
ITU-T
Recommendation E.155.
IPRS will be based on Universal International Premium Rate Number (UIPRN)
assignments.
Applications for UIPRN assignments will be accepted beginning 2 April 2001,
according to the
process outlined by ITU.
UIPRNs will be assigned starting 7 May 2001.
UIPRN service will use country code +979, followed by a 1-digit
charge band to indicate a category of call cost, then an 8-digit
subscriber number. That is, the following formats of UIPRN will be seen:
- +979 1 xxxxxxxx: charge band 1
- +979 3 xxxxxxxx: charge band 2
- +979 5 xxxxxxxx: charge band 3
- +979 9 xxxxxxxx: special charge band
are specified by ITU-T.
Information on the significance of the charge bands is unclear, and
presumably to be defined by agreements among participating UIPRN
carriers and could vary according to each participating nation.
Operators Bulletin (April 1999)
makes reference to the International
Premium Rate Service (IPRS), expected to be provided via country code 979.

An International Shared Cost Service (ISCS) will allow callers to contact
international services charged at the national call cost of the originating
country. The price of ISCS calls to the caller would be between toll-free
and the normal international rate.
Applications for the Universal International Shared Cost Numbers (UISCN)
for ISCS will be received from 2 May 2001, with UISCNs to be assigned from
7 June 2001.
are available from ITU-T.
Information on ISCS and UISCNs is available from
ITU-T.
A "national rate" service exists in some nations such as UK and
Germany, to offer call charging between toll-free and regular long distance
service.
ISCS is also described on the

International Telecommunications Public Correspondence Service (ITPCS) |
+991 |
Country code +991 was reserved by
as of mid-2000
for a trial of an "International Telecommunications Public Correspondence
Service". There are no further details available regarding the
nature of the proposed service.
However, the term Public Correspondence Service often refers to maritime
radio systems (coastal or inland). This could have been conceived for
a test of a new type of direct-dialled maritime radio service.
However, it was announced that an assignment under +991, specifically
the range +991 001, was assigned to
for trials of the
ENUM scheme. ENUM seeks
to link telephone numbering with Internet addressing. Neustar has
a temporary assignment of +991 001 until 6 December 2002.
VISIONng was also approved in 2002 for an ENUM trial, using a number range
within the UPT country code: +878 10.

Telecommunications for Disaster Relief (TDR) |
+888 |
Country code +888 was formally assigned in May 2007 for use by the
United Nations Office for the Coordination of Humanitarian Affairs (OCHA)
for disaster relief communications purposes.
This country code would allow temporary telephone numbering to be
established in disaster-stricken regions where the conventional
telecommunications service is unavailable. OCHA has exclusive rights
to determine the numbering structure following the +888 country code.
This would allow various UN agencies and operating locations to be integrated
under +888 by specifying service digits after 888 then the agency
number e.g. UNICEF numbers could be reached as +888 42 xxxxxxxx, if '42' were
chosen as a prefix code for that agency. Numbering may be discontinued
once a disaster situation is resolved, then reassigned for a later incident.
Under Mobile Country Code 901, Mobile Network Code 88 was also assigned
for UN disaster relief purposes. The announcement of +888 also replaces
country code +999 which was initially reserved for disaster relief service
in ITU's February 2004 country code listing.
+999 is now reserved for a "future global service".

Annex to ITU Operational Bulletin #930 (15 April 2009, country code
assignments)
Workshop
on Telecommunications for Disaster Relief (TDR)
conducted by
in Geneva 17-19 February 2003.
Minutes from ATIS
Network Interconnection/Interoperability Forum (NIIF) indicated that
Verizon submitted the proposal for country code 999 TDR to ITU's
Study Group 2 in 2003. (ATIS/NIIF #22, point 32, link broken as of
September 2009).

Telex (teletype) |
- - - |
Telex or teletypewriter systems had their own national and international
numbering plans, and were generally distinct from the conventional telephone
networks.
ITU maintains the assignment of Telex country codes. Telex country codes have
little in common with telephone country codes as the assigned numbers were
radically different.
For list of telex country or destination codes (ITU Recommendation F.69),
see
1999 ITU document on telex code assignments..
Telex country codes were 2 or 3 digits, with first digit indicating
the world region or service:
Leading digit(s) Region/service
================ ==============
0 (unused)
1 maritime mobile, other special service
2 North America
3 South America (except 37, 39)
37 Central America (integrated code)
39 some Caribbean areas
4 Europe, some North African nations
49 some Middle East
5 Europe
58 Maritime/satellite e.g. Inmarsat
6 Eastern Europe, Israel
7 Pacific
78 some Asia
79 Afghanistan
8 Asia
88 Iran
89 some Asia, some Middle East
9 Africa

Time 'T' (expanded numbering lengths) |
- - - |
Until December 1996, an international telephone number was restricted to
a maximum of twelve digits for the combined country code, and national
number dialed (including any area or intercity codes).
As of 31 December 1996, 2359 hours UTC, the maximum digit length
to be allowed in international dialling was increased to fifteen digits.
More digits are thus allowed within the various countries' numbering plans.
This deadline was referred to as Time 'T'.
More information on Time 'T' can be found in a recent ITU
note
.
Information from ITU-T Circular 14. Also older ITU circulars 128 and 180
had information on Time T. The Circulars can no longer be found on
.

Universal Personal Telecommunications (UPT) |
+878 |
There is a reservation of country code +878 for Universal Personal
Telecommunication (UPT) services. +878 was previously reserved for use in
national mobile purposes, apparently for use at the option of nations that
wished to use it.
Sources say that the reservation of +878 for UPT was decided at
the May 1996 ITU-T Study Group 2 meeting, and listed as of the 1 March
1999
Operational Bulletin.
There were no reports that any nations made use of this country
code for testing or national purposes, however. There was also no explanation
why 878 was sought for UPT service when other unused country code assignments
were available. An evident speculation is that 878 spells out "UPT" on
some telephone dial schemes.
As of early 2002, +878 10 range of numbers was assigned to VISIONng
for use in an ENUM trial. See
ENUM information in ITPCS for other references
to ENUM development.

the web. Additional tip of August 1999 courtesy Vince Humphries)
In June 2004, a press release announced that
Sentiro (Telesoft)
was to deploy the first worldwide commercial ENUM service. Numbers in
the +878 10 7472 range were to be used to provide a worldwide portability
for various types of voice and data communications.

Management of Country Code assignments |
- - - |
Recommendation E.193
establishes a plan to expand the number of available country codes should
the need arise. Country splits, and the implementation of new services
have caused many new country code assignments in recent years.
Also, a new
ITU-T
Recommendation E.195
will specify the ITU's numbering resources administration. The ITU
is expected to form a Numbering Administration Group (NAG) as part of its
Telecommunication Standardization Bureau (TSB), to handle telecommunications
numbering assignments such as telephone country codes, telex country
codes, Universal International Freephone Numbers,
or other numbering resources for which the ITU would be responsible.

Other International Notes |

Country code +888 is apparently unassignable and reserved for some unknown
global service. While 888 is used as the second toll-free service code
in the North American Numbering Plan, one might expect
that the capacity under the
International Freephone +800 country code would
be expandable instead of assigning new country codes to supply added
international freephone numbering capacity.
