About .ไทย domain
.ไทย is the internationalized country code top-level domain (IDN ccTLD) representing Thailand, written entirely in the Thai script. It is managed by the Thai Network Information Center Foundation (THNIC), the same registry that operates Thailand's ASCII ccTLD .th. The domain was delegated by ICANN on April 19, 2010, following Thailand's successful application through ICANN's IDN Fast Track process, which began in December 2009. Its Punycode representation is xn--o3cw4h, and the label itself translates directly to "Thai" in English.
Who can register .ไทย domain
Registration eligibility for .ไทย mirrors the rules and restrictions applied to .th, meaning registrants are generally expected to have a connection to Thailand. The extension is structured around a set of second-level domains that impose category-specific requirements:
- .ศึกษา.ไทย — educational institutions and educational service providers
- .ธุรกิจ.ไทย — commercial enterprises, businesses, and trademark holders
- .รัฐบาล.ไทย — government agencies
- .องค์กร.ไทย — non-profit corporations, charitable organizations, or entities not fitting other categories
- .ทหาร.ไทย — military units
- .เน็ต.ไทย — network service providers
Prospective registrants should confirm which second-level category applies to their organization before proceeding, as documentation requirements vary by category.
How to register .ไทย domain
Search for availability. Use a registrar that supports Thai-script IDN domains to check whether your desired .ไทย label is available. Keep in mind that domain labels must be between 1 and 63 characters in ASCII-compatible encoding, and only Thai characters, hyphens, Arabic numerals 0–9, and Thai numerals ๐–๙ are permitted.
Compare registrar options and features. Not all registrars support IDN ccTLDs, so verify that the registrar you choose can properly register and manage .ไทย domains. Review the registration term options, renewal pricing, and any included management tools before committing.
Complete checkout and submit required documentation. During registration, select the appropriate second-level domain category (such as .ธุรกิจ.ไทย for a business) and provide any supporting documentation required for that category. Ensure your contact details are accurate, as WHOIS accuracy is typically required under .th-aligned policies.
Configure DNS and verify your registration. After checkout, update your DNS records to point to your hosting provider or name servers. Confirm that your registrar has correctly encoded the Thai-script label in Punycode (xn--o3cw4h) for DNS resolution, and test that the domain resolves correctly in supported browsers.
Typical uses of .ไทย domain
.ไทย is most commonly used by organizations and individuals in Thailand who want to present an entirely Thai-language web address to local audiences. Businesses, government bodies, educational institutions, and non-profits operating within Thailand choose this extension to signal local identity and improve accessibility for Thai-speaking users who are more comfortable reading native-script URLs. It serves as a culturally resonant alternative to the ASCII .th ccTLD, particularly for organizations whose primary audience reads and types in Thai script rather than Latin characters.
Tips for registering .ไทย domain
- Character rules are strict. Only Thai consonants, vowels, tone marks, special Thai symbols, Thai numerals, Arabic numerals 0–9, and hyphens are permitted in the label — non-Thai Latin characters are not allowed as part of the Thai-script label itself.
- Second-level category selection matters. You must register under the correct second-level domain (e.g., .ธุรกิจ.ไทย for commercial use) and may need to provide documentation proving eligibility for that category before the registration is approved.
- Label length limit. The domain label, when converted to ASCII-compatible encoding, must not exceed 63 characters, so very long Thai-script strings may need to be shortened.
- Verify IDN support at your registrar. Because .ไทย is an IDN ccTLD, confirm that your chosen registrar fully supports Thai-script domain management, including correct Punycode handling, before purchasing.
- Renewal policies follow .th rules. Registration and renewal policies are governed by THNIC's .th and .ไทย Domain Name Registration Policy, so review that document for grace periods, redemption windows, and transfer conditions specific to this extension.
