Domain .th - national domain: Thailand

.th domain information

The .th domain is the official country code top-level domain (ccTLD) for Thailand. Managed by the Thai Network Information Center Foundation (THNIC), it is the primary and most authoritative online identifier for companies, organizations, and individuals operating in or targeting the Kingdom of Thailand.

Registration rules

Registration under .th is highly restricted and only available during specific application windows set by the local registry. These opportunities may not always be open, and advance verification is required.

Only entities that already hold a registered third-level Thai domain (such as .co.th) or a corresponding trademark are eligible to apply. The domain name must exactly match the registered trademark. If the trademark is not registered in Thailand, the applicant must appoint an official local representative authorized in writing to register the domain on their behalf.

Due to the complexity of the .th registration process and strict eligibility rules, we strongly recommend contacting us in advance to confirm whether your organization qualifies for registration.
