A two-letter internet domain name extension that represents a specific country, territory, or geographic region. Country code top-level domain (ccTLD) extensions are used to indicate a website or online resource’s target audience based on its location. They follow the ISO 3166-1 alpha-2 standard, which assigns two-letter codes to countries and territories.
How ccTLDs Work
Country code top-level domain (ccTLD) identifiers are two letters long. All two-letter top-level domains are ccTLDs. Country code extension applications began in 1985. The registered country code extensions in that year included .il (Israel), .uk (United Kingdom) and .us (United States). The registered country code extensions in 1986 included .au (Australia), .de (Germany), .fi (Finland), .fr (France), .is (Iceland), .jp (Japan), .kr (South Korea), .nl (Netherlands) and .se (Sweden). The registered country code extensions in 1987 included .ar (Argentina), .ca (Canada), .ch (Switzerland), .cl (Chile), .dk (Denmark), .my (Malaysia), .nz (New Zealand) and .no (Norway).
- Examples: The .us extension represents the United States, .uk represents the United Kingdom, .de represents Germany, and .jp represents Japan.
Benefits of Using ccTLDs
Using a ccTLD can help businesses signal to search engines and users that their website or content is designed for a specific country or region. This can improve search engine rankings and the user experience for the target audience, and provide a clear indication of the website’s intended market.
