# Best domain registrars in Thailand

Thailand has the strictest naming rule in this set, and it is about the name itself, not just the registrant. A .co.th domain requires the applicant to hold a matching trademark, service mark, certification mark or collective mark, and the domain must be exactly the registered mark with no abbreviation or extension. Applicants with legal standing in Thailand prove it with a passport or a legal-entity registration certificate plus supporting documents. A foreign trademark registered outside Thailand needs a local representative office that is a juristic person in Thailand, or a power of attorney appointing an authorised representative. No registrar we track sells any Thai string.

## ccTLDs

### .co.th

Commercial second level, the standard identity for a Thai company.

- Eligibility: Restricted and name-matched. The applicant must hold a trademark, service mark, certification mark or collective mark, and the domain must exactly match the registered mark. Thai Department of Intellectual Property registrations get first priority; foreign marks require a Thai representative office or a power of attorney.
- Notes: The THNIC Foundation assigns T.H.NIC Company Limited to handle applications across the seven categories under .th and .ไทย. The exact-match rule is the constraint most foreign applicants underestimate.

### .ไทย

Thailand's Thai-script internationalised ccTLD, run under the same policy.

- Eligibility: Governed by the same THNIC policy and category structure as .th.
- Notes: Punycode .xn--o3cw4h. A separate delegation from .th.
