From Wikipedia, the free encyclopedia
.th is the Internet country code top-level domain (ccTLD) for Thailand. It is administered by T.H.NIC Co., Ltd. (THNIC), formerly known as Thai Network Information Center Foundation.
It appears that the .th domain only admits third level domain registrations under its second level domains.
Registration of a .co.th domain name is a complicated procedure, for this reason most Thailand websites prefer to use a .com name. In order to register a .co.th 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 acme.co.th you would need to have a registered company called Acme Co., Ltd.
A company can only register a single .co.th domain, making it impossible to facilitate easy location of a company's products by using a variety of words or product names as their domain names.
