.th is the Internet country code top-level domain (ccTLD) for Thailand.


It is administered by T.H.NIC Co., Ltd. (THNIC), the corporate entity of Thai Network Information Center Foundation.


Registration of a domain name is a complicated procedure, for this reason most Thailand websites prefer to use a .com name. In order to register a domain name the registrar in Thailand requires copies of company documents in the same name as the required domain name, so for example if you required you would need to have a registered company called Acme Co., Ltd.

A company can only register a single domain with the company name or initial name of company, and/or one domain name per trademark.

Second level domains

THNIC admits .th registration only third-level domain under seven groups of predefined second-level domains:

Second top domain

In 2010 a new top domain was registered and introduced for Thailand, intended for domain names in the local language. This top domain is .ไทย. As of 2011, thousands of sites with this domain are active.

It appears that the Thai second-level .ไทย domains are assigned directly to sites with English domain names. Another groups of .th domains must use third-level .ไทย domains, as in the table above.
