 Section Index:

This section deals with special services and numbering changes such as Inmarsat and International Freephone. These items do not correspond to a particular nation or geographic region, and are thus considered "non-geographical" in nature.

|DSN| Defense Switched Network DSN
The U.S. Department of Defense's Defense Switched Network (DSN) is a separate international communications network, outside the usual Public Switched Telephone Network (PSTN). The system can be thought of as a widespread PBX system for military uses.

DSN numbering is similar to the North American Numbering Plan: three-digit area codes followed by seven-digit numbers. The area codes are:

312 Continental United States (CONUS)
313 Caribbean, Central America
314 Europe
315 Pacific, Indian Oceans
317 Alaska
318 Southwest Asia
319 Canada (as of 5 September 2000, formerly under 312)

For further information on DSN, see:

AUTOVON (AUTOmatic VOice Network) was DSN's predecessor. Information on that system can be found in reports on the TELECOM Digest archives:

5 September 2000 - Canadian Switched Network (CSN) area code 319

The Canadian Switched Network (CSN) is operated by Canada's Department of National Defence 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.

|GMSS| Global Mobile Satellite System (GMSS) +881
ITU 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, Globalstar etc. Some of the satellite services had serious financial difficulties early in their operations, but Ellipso, Globalstar 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.)

Some information articles mentioning the +881 country code for GMSS include:

|Inmarsat| Inmarsat +870 to +874
Inmarsat 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:

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:

+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:

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 announcement from Inmarsat 20 January 2005 (via ITU) 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.


Report of 1 July 2015 implementation deadline: from Telenor Satellite Mobile.

Regarding 1 January 2009 advanced implementation: this report was issued by ETO, but is no longer available since ETO's activities were absorbed into ERO.

31 December 2007 - Inmarsat-A service discontinued

Inmarsat 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 in the +870 77... range.

Source: Inmarsat announcements via ITU (22 September 2005, updates previous announcement 24 December 2002).

BGAN numbering was also the topic of a discussion paper (via ATIS).

|UIFN| 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 ITU's information on International Freephone (UIFN) service.

Some international freephone information may be available via ICB Toll Free.

Also, there is an article which outlines problems of the UIFN implementation Total Telecom Article (International freephone is localized and costly, 19 February 2001).

|Intl| International Networks +882, +883
The ITU has made various assignments under country code +882 and more 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.

See also, ITU List for +882 (in PDF format).

The following +882 assignments and reservations and were indicated as of April 2009, under the latest available listing. The following is subject to new, changed or cancelled entries. Each item in the following list consists of the +882 xx number, followed by the carrier and service.

@ at the end of a line indicates the numbering is assigned (otherwise, numbering is reserved, presumably pending service implementation):

Telespazio Emsat (+882 13) - warning on unauthorised use

Telespazio issued an announcement (12 December 2004, via ITU) advising that its +882 13 code was only for use with its Emsat satellite network service. Use of the number range for other services such "web diallers" is unauthorised.

Emsat numbering is +882 13 aa xxxx where the "aa" portion is an "area code" representing a service provider, followed by 4 digits specifying the subscriber number.

Number ranges as of 12 December 2004:

Global Networks Switzerland - Antarctic service +882 34

Global Networks Switzerland was assigned country code +882 34 to operate in Antarctica. These numbers are distinct from the existing Antarctic access through +672 (Australian External Territories). +882 34 is now in service, although some carriers may still have not yet enabled access.

For clarification between +882 34 and +672, see Global Networks Switzerland announcement, 11 May 2004 via ITU.

The +882 34 numbering ranges are as follows (as of June 2004):

Number range        Service type
============        ============
+882 34 1xx xxx...  Carrier Selection and service numbers (variable digits)

+882 34 906 xxxxxx  premium (high cost)
+882 34 999 xxx...  test numbers (variable digits)

+883 assignments

+883 country code assignments were made by ITU since June 2007:

ITU +881/+882/+883 assignments (MS Word format, old list)

iNum details

Various telecom companies provide iNum numbers (+883 5100 series) which are co-ordinated through Voxbone. Although the format was initially described as 5-digit subscriber numbers (+883 5100 xxxxx), the actual service now appears to involve +883 5100 followed by 8 digits.

The particular carrier company providing an iNum may be determined by the initial digit or two following +883 5100, such as seen in these examples:

Range                Service
-----                -------
+883 5100 01 xxxxxx  Blasterphone
+883 5100 04 xxxxxx  Voxalot

|IPRS| 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:

Number format details 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.

Network Operators Bulletin (April 1999) makes reference to the International Premium Rate Service (IPRS), expected to be provided via country code 979.

|ISCS| International Shared Cost Service (ISCS) +808
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. Details of the start-up schedule 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 Toll Free Forum.

The operation of International Shared Cost Service was defined in ITU Recommendation E.154.

|ITPCS| International Telecommunications Public Correspondence Service (ITPCS) +991
Country code +991 was reserved by ITU 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 Neustar 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.

|Telex| 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".

ITU Letter: Assignment of codes for United Nations Disaster Relief Activities (4 May 2007)

Annex to ITU Operational Bulletin #930 (15 April 2009, country code assignments)

Workshop on Telecommunications for Disaster Relief (TDR) conducted by ITU 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| 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

|TimeT| 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 information 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 ITU's website.

|UPT| 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 ITU 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.

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.

|Mgt| Management of Country Code assignments - - -
ITU-T 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| 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.
