Whenever you want to make a phone call to another country, you will need a country code. These codes are used in the international telephone numbering plan. These codes make it easy to make a phone call anywhere in the world. The codes are created by the International Organization for Standardization. There are three ways to use these codes: the two-letter format, the three-letter format and the three-digit numeric format. See the list of countries and their country codes on this page. Most countries have two-digit country codes. Some smaller countries have three-digit international phone codes. These codes vary from country to country. In the UK, for example, a phone number might be written as +44 1296 999999. The codes are based on country names and geographic information. Some of these countries are grouped into "calling zones" and the codes are assigned to the countries that fall within them. The zones are also organized by geographic location. The two-letter code is most commonly used in the European Union. The United Nations uses three-letter codes. The two-letter codes are typically used as an abbreviation when doing statistical analysis. The three-letter code is more closely related to the country's name. It is also used in geographic information systems. The three-digit numeric code is useful for people who want to use Latin script. Some smaller countries are still using two-digit codes. They were originally assigned two-digit codes to compensate for the longer domestic phone numbers. However, all new assignments have been three-digit since the 1980s. The International Telecommunication Union-T (ITU-T) is a special agency of the United Nations that develops global standards for telecommunication. It also assigns country dial codes to countries in the "List of ITU-T Recommendation E.164 Assigned Country Codes." The list is updated whenever there is a change in world geopolitics. The Country codes are listed in alphabetical order by country. The list can be used to find large statistics or to map a country. Countries that are geographically close to each other usually have similar codes. This makes it easy to place calls to a country anywhere in the world. Countries are also grouped into "calling zones" for geographic convenience. These codes can be used free of charge by the users. Some codes are assigned to countries and groups for national recognition. Others are used for language codes. Some of these codes are also used for currency codes. The ISO publishes the country codes, and there are two maintenance agencies that update the codes. The codes are also available on the Internet Browsing Platform. This platform allows users to register for notifications about changes. The ISO also allows free use of language codes. The country codes can be found in three different databases. One is the OBP product, Country Codes Collection. The other two databases are the Online Browsing Platform and the Internet Domains List. All three databases have lists of country codes in three different formats. Using these lists is very useful. The list of country codes is updated with changes in the standard, and is available on the Online Browsing Platform. Users can also find the history of the standard and its changes.
