international call prefix or dial out code is a trunk prefix used to select an international telephone circuit for placing an international call. The prefix must be dialed before the country calling code and the destination telephone number. It is synonymous with international access code or exit code.
International Telecommunication Union (ITU) recommends the sequence 00 as a standard for an international call prefix, and this has been implemented by many countries, but not all of them. [1 ]
When phone numbers are published for use abroad they typically include the country calling code, but show a plus sign (+) prefix in place of any international call prefix, to signify that the caller should use the prefix code appropriate for their country.
Many phones allow this "+" to be entered in their saved number lists, often by holding down the '0' key (most
GSM mobile phones) or with two consecutive presses of the * key. When making a call the system then automatically converts the "+" to the correct international prefix, depending on where the phone is being used, which enables callers to use the same stored number when calling from either their own country or any other. [3 ] Example [edit ] Variations [edit ]
telecommunications service providers or mobile network operators (wireless carriers) have different international call prefix codes which callers or subscribers can use to route calls through specific networks, sometimes with special pricing arrangements.
Many countries also provide alternative dialling arrangements for calls to neighbouring countries.
Some of these variations from the generic codes are shown in the list below (but may be out of date).

For example, if the subscriber dials 018-1-202-555-1212, the call will be routed to North America via Xfone. 011 - Any country in the North American Numbering Plan (NANPA) American Samoa Anguilla Antigua and Barbuda Bahamas Barbados Bermuda British Virgin Islands Canada Cayman Islands Dominica Dominican Republic Grenada Guam Roatan, Honduras Jamaica Marshall Islands Micronesia Montserrat Northern Mariana Islands Palau Puerto Rico Saint Kitts and Nevis Saint Lucia Saint Vincent and the Grenadines Sint Maarten Trinidad and Tobago Turks and Caicos Islands United States of America United States Virgin Islands 10, where xx xx is the international carrier selection code Georgia (00 prefix for default carrier is also admissible instead of 10xx) 1007 Caucasus Online 1010 MagtiCom 1011 SystemNet 1012 SystemNet 1013 MacroCom 1015 SakTelComPlus 1016 Silknet 1017 SystemNet 1018 Global Erty 1019 Akhtel 1027 CallCenter 1040 IntelPhone 1041 V-TEL Georgia 1050 MagtiCom 1051 Caucasus Online 1052 Alex Development Georgia 1053 Sky Service 1054 Lagi 1057 NewCom 1060 GeoNet 1061 Silknet 1062 Geocell 1063 Black Sea Telecom 1064 Central Communication Company of Georgia 1065 Akhali Kselebi 1067 GeoTel 1069 Service 1072 TelMax 1075 Wi-MAX Georgia 1076 Silknet 1094 Warid Telecom Georgia 1, where xx0 xx is the international carrier selection code 8~10 Belarus Kazakhstan Tajikistan Turkmenistan Uzbekistan 8~, where xx xx is the international carrier selection code Russia (for "carrier hot choice" subscribers) 99 Finland, where to encourage competition between international telephone carriers, a system of prefixes beginning with 99 was introduced in addition to the 00 prefix. For example, if the subscriber dials 990-1-202-555-1212, the call will be routed to North America via TeliaSonera. 990 – TeliaSonera Finland Oyj 991 – Elisa Oyj 992 – Globetel Oy 994 – TDC Oy FINLAND 99511 - Helistamine OU 99532 – Elisa Oyj 99533 – TDC Oy FINLAND 99541 – DNA Oy 99555 – DNA Oy 99559 – Elisa Oyj 99566 - Datalahti Oy 99577 – TDC Oy FINLAND 99588 – Globetel Oy 99590 – TeliaSonera Finland Oyj 99599 – Nettia Oy 996 – DNA Oy 9977 – Elisa Oyj 998 – Orange Business Finland Oy 999 – Elisa Oyj Historic international prefixes [edit ] 0 Bahrain (now 00) El Salvador (now 00) Falkland Islands (now 00) Myanmar (now 00) Malta (now 00) 00 Cambodia (now 001) Mongolia (now 001) Sint Maarten (now 011) Tanzania (now 000) 0030 Hong Kong (CTI, which now uses 1666) 009 Denmark, including Faeroe Islands and Greenland (now 00) Sweden (now 00) 05 Fiji (now 00) Papua New Guinea (now 00) 09 Namibia (now 00) Netherlands (now 00) South Africa (now 00) 16 Somalia (now 00) Republic of Ireland (now 00) 19 France (now 00) Central African Republic (now 00) 8~10 Estonia (now 00) Azerbaijan (now 00) Armenia (now 00) Georgia (now 00) Kyrgyzstan (now 00) Latvia (now 00) Lithuania (now 00) Moldova (now 00) Ukraine (now 00) 95 for NANPA and 98 for the rest of the world 99 the former Yugoslavia (successively replaced by successor republics with 00) India (now replaced with 00) See also [edit ] Notes [edit ] ^ There is an additional dial tone that applies only to calls from landlines.
