About .th domain
.th is a country code top-level domain (ccTLD) delegated for Thailand. It is operated by the Thai Network Information Center Foundation (THNIC) and was first delegated in 1988. The registry manages registrations at both the second and third levels under various categorized second-level domains. It functions as a national domain extension with specific eligibility and verification processes.
Who can register .th domain
Registration eligibility for .th domains depends on the specific second-level domain (SLD) chosen. For the most common commercial SLD, .co.th, registration is restricted to registered business entities, with the domain name required to match the company or trademark name. Other SLDs like .ac.th, .go.th, and .mi.th are reserved for academic, government, and military entities respectively. The .in.th SLD is open to individuals (including foreign nationals with a valid Thai work permit), companies, and organizations, provided the registrant has a verifiable address in Thailand.
How to register .th domain
- Determine Eligibility and Choose an SLD: First, identify which second-level domain (.co.th, .in.th, .ac.th, etc.) matches your entity type and gather the necessary documentation, such as company registration papers or personal identification.
- Search for Availability: Use the THNIC website or an accredited .th registrar to check if your desired domain name is available under your chosen SLD. Note that some names, like geographic or cultural terms, may trigger an extended verification process.
- Submit Application and Documentation: Complete the registration application through an accredited registrar and submit all required supporting documents for THNIC's review. For second-level .th domains, a significant application and annual fee applies.
- Activate and Configure: Once THNIC approves your application and you complete payment, your domain will be activated. You can then configure its DNS settings through your registrar's control panel to point to your website or email service.
Typical uses of .th domain
The .th extension is predominantly used by entities with a clear connection to Thailand. Businesses operating within the country commonly use .co.th to establish local credibility, while individuals and a broader range of organizations opt for .in.th. Government agencies, educational institutions, and non-profits utilize their respective specialized SLDs (.go.th, .ac.th, .or.th) for official communications. Users choose this TLD to signal their physical or operational presence in Thailand, often for local search engine optimization and consumer trust.
Tips for registering .th domain
- Registrations under most .th SLDs require submitting documentation (e.g., business license, ID card) to an accredited registrar for verification by THNIC before the domain is activated.
- The .in.th SLD has more flexible eligibility, open to individuals and entities with a Thai address, including foreign nationals who hold a valid Thai work permit.
- For the commercial .co.th SLD, a company can typically register only one domain matching its company name and one per registered trademark it holds.
- THNIC offers direct second-level .th registrations (e.g., example.th) through a separate, high-cost application process with an annual fee, distinct from the standard third-level registrations.
