Every country has both a country calling code used to dial into a country, and an International Direct Dialling (IDD) (also called a international call prefix or international access code) code used to dial out of the country. The ITU recommends 00 as the general standard, and this has been implemented by a large number of countries, but not all of them.[1]
From a mobile device, one can use a "+" instead of the local IDD code, "+" is universal prefix for all international calls. The "+" can be reached by holding down the "0" key until it turns into a "+".[2]
This page lists the exceptions.
[edit] Syntax
International phone numbers are usually written with a plus sign (+) before the phone number representing the international call prefix. The plus sign indicates the code required to dial out of one's country code area as shown in the list below, such as 00 in most of Europe, 011 in the United States, and other short codes in other parts of the world. Many phones allow this "+" to be entered in the number list, often by holding the '0' key (most GSM mobile phones) or with two consecutive presses of the * key. It is then automatically converted to the correct international prefix when making a call, which enables callers to use the same number from any country.
[edit] For example
A UK phone number written as +44 1234 567890 would be dialed as 567890 from the '01234' linked numbering scheme exchanges in the UK; as 01234 567890 from elsewhere in the UK; and as 00 44 1234 567890 from countries using the 00 international access code. For countries using a prefix other than 00, simply substitute that for 00 in the last example; for example, from North American Numbering Plan countries (including the United States and Canada), dial 011 44 1234 567890.
Many states also provide alternative dialling arrangements for calls to neighbouring countries.
[edit] International Call Prefix
Note: ‘~’ means to await a tone before continuing.
- 00
- All countries not listed below.
- 0x0
- Mauritius ('x' represents one digit defining an 'International Long Distance' operating company.)
- 00 Works only from pay phones and '+' only from mobile phones.[3]
- 00x
- Thailand (001,004,005,006,007,008 and 009)
- 00X / 00XXX
- Colombia ('x' represents one digit carrier -Telefónica Telecom, UNE or ETB- and 'xxx' represents the new three digits' carriers -Comcel, Telmex or Emcali, among others.-)
- 010
- Japan. Note that many Japanese phone subscriptions do not include international calls. If the one in use does not, you have to dial a prefix of three or four digits before the 010 prefix to select an international phone carrier. Even if your phone subscription includes international calls, you may use one of those prefixes to select a phone carrier other than the usual one. Selecting a phone carrier is mandatory if you use a public payphones. Different codes available:
- 001 010 (KDDI)
- 0033 010 (NTT)
- 0041 010 (Japan Telecom)
- 0061 010 (Japan Telecom IDC) NB: Japan Telecom and Japan Telecom IDC are different!
- 01x
- Israel ('x' represents one digit defining a carrier. Also supports the ITU standard.)
- 1xx0 ('xx' represents two-digit Chilean Carrier Selection Code; For example, an Argentine phone number written as +54 11 23456789 would be dialed as 1230 54 1123456789 or 1880 54 1123456789)[5]
- 15500
- El Salvador for a land line from Telecom, otherwise 00 for other telephone companies.
- 8~10
- Was a standard for the Soviet Union and so remains one for several post-Soviet countries:
- 8~xx, where 'xx' is the international carrier selection code
- Georgia
- 07 Caucasus Online
- 10 Telecom Georgia
- 11 Egrisi (Akhali Kselebi)
- 16 United Telecom of Georgia
- 18 Global One
- 54 Lagi
- 60 Geonet
- 69 Service Ltd.
- Russia (for "carrier hot choice" subscribers). International carrier selection codes as of August 2008:
- 90
- 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.
[edit] Historic International Prefixes
- 95 for US (NANP number) and 98 for the Rest of the world
- 09~
- formerly in Netherlands (replaced by 00 in the late 1990s)
- 19~
- formerly in France (replaced by 00 in the late 1990s)
- 99
- 99 was the standard for the former Yugoslavia. Successor republics have gradually been replacing this with the standard 00; Serbia became the final republic to adopt 00.[citation needed]

- ^ This code will let the dialer choose his primary IDD carrier, usually being the telephone company he is subscribed to. A telephone line can subscribe to multiple IDD carriers in Hong Kong, and those carriers have their own international call prefix, which begins with 00 (3-4 digits), 15 (4 digits) or 16 (4 digits). See The Numbering Plan for Telecommunications Services in Hong Kong for complete code list.
- ^ Although in Chile all the carriers use the 1 prefix, the number of the carrier in advertising and common usage includes the 1 prefix as a part of the number.
- ^ The domestic call prefix 8 and international call prefix 8~10 are to be replaced by the ITU-recommended dialling prefixes of 0 and 00. The first step will be to replace area codes beginning with the digit '0' with ones beginning with '4', hence Moscow 095 becomes 495. See also Telephone numbers in Russia.
