ccTLDs: geographical domains

There are more than 240 ccTLDs (country code Top Level Domains), the geographical internet domains made up of two letters.

History of ccTLDs

To improve the international exchanges of goods and information, the International Organization for Standardization (ISO) established in 1974 an international country code standard to identify names of countries or geographical parts of the world (post codes...). This standard is ISO 3166.

The two-letters version of ISO 3166 (3166-1) are used to establish the ccTLDs list, the geographical internet domains in two letters. For example, ISO code for France is FR and its ccTLD is .fr.

How to find a ccTLD or information about it?

Two steps:

1. First, you have to know the ISO code or the ccTLD of the country you are searching about: See list.
   For example: ISO code / ccTLD for Italy is .IT.
   
   
2. Then, once you got this code, you can consult the list below. You have just to click on the first letter of the code.
   For example: to get information about the italian internet domain, just click on the first letter of the ISO code - ccTLD for Italy: I (for .IT).
