.co.th domain registration rules - Thailand

The registration of a .co.th domain is intended for


  • registered in Thailand: ONLY ONE .co.th domain name allowed, identical to the company name;
  • NOT registered in Thailand: may request ONLY ONE .co.th domain name based on a registered trademark. If the trademark is NOT valid in Thailand, registration also requires a local representative. If the client does not have one, Dominiando can provide the local presence service. The domain name must be identical to the trademark name.

Owner of a registered trademark:

  • valid in Thailand: can ask for a .co.th domain name that is identical to the trademark;
  • NOT valid in Thailand (e.g. a European trademark): can ask for a .co.th domain name that is identical to the trademark name, however, with the obligation to indicate a local agent as owner's representative, giving specific authorization.

You can register multiple .co.th domain names ONLY based on registered trademarks, provided that the domain name coincides with the name of each trademark (translations of the trademark are not accepted).
If the trademark expires, the domain is immediately deleted.

The applicant must produce one of the following documents:

  • Company Limited / Limited Partnership's Registration Document (Thor-Khor-0401)
  • Company Limited / Limited Partnership's Certification Paper
  • VAT Registration Document (Por-Por-20)
  • VAT Modification Request Paper (Por-Por-09)
  • Overseas Commercial Permission Document (Thor-Khor-0506)
