Domain .co.th - national domain: Thailand

.co.th domain information

Only third-level domains are registered, mainly .co.th. It is not possible to register a domain directly with the .th extension.

Due to very large restrictions on the availability of these domains, the .com domain is common in Thailand.

Registration of .co.th domains is only possible for companies in the following cases:

• The registered domain name matches the company name or its abbreviation. Registration is possible for a foreign company if the company has its local representative (a company based in Thailand) and formally authorizes him to register the domain. There is a limit of one domain per company.
• The registered domain name matches the name of the registered trademark. For marks registered in Thailand by the Intellectual Property office, there is no need for a local representative office. For non-Thailand characters, it is required to have a local representative (company) in Thailand and authorize it for domain name registration purposes.

Please also read the requirements for the .th domain. If you wish to register a .co.th domain name, please contact us in advance to verify your right to register.
