Country domains (ccTLDs)
Every country code top-level domain, the two-letter internet suffix such as .se (Sweden) or .io (British Indian Ocean Territory). Start from the domain to find the country, or from the country to find its domain.
A ccTLD is derived from a country’s ISO 3166-1 code. Some, like .io, .co and .tv, are also widely used far beyond their home country.

Frequently asked questions
Which country does the .io domain belong to?
.io is the country code top-level domain of British Indian Ocean Territory. It is widely registered far beyond its home territory, especially by technology companies, because 'IO' reads as input/output.
Which country does the .tv domain belong to?
.tv is the country code top-level domain of Tuvalu, a Pacific island nation. It is widely registered by broadcasters and streaming sites far beyond the islands because it reads as 'television'.
Which country does the .co domain belong to?
.co is the country code top-level domain of Colombia. It is also marketed worldwide as a short alternative to .com.
Which country uses the .se domain?
.se is the country code top-level domain of Sweden, taken from its ISO 3166-1 code SE.
How is a country's domain ending decided?
Country code top-level domains follow the two-letter ISO 3166-1 alpha-2 standard: Sweden's code SE becomes .se, Bolivia's BO becomes .bo, Vietnam's VN becomes .vn. IANA delegates each ccTLD to a registry in or for that country or territory.
Do any countries share a domain?
A few ccTLDs cover more than one entry in the table below, such as .nl, which serves both the Netherlands and the Caribbean Netherlands. Conversely, some territories have their own domain despite not being independent countries.
