Buy .th Domain Name

.th names are not registered instantly; they are granted with committee approval in the application rounds THNIC opens. The process works like this:

1. You place your order, and we ask for your organisation, trademark or identity documents.
2. Your application is submitted through T.H.NIC Co., Ltd. to the round that is open, or the next one to open.
3. When the round closes, the committee appointed by THNIC reviews the applications together; in round 3/2026 the review runs from 1 to 15 December 2026.
4. Approved names are announced on 15 December 2026 and the registration is completed.

Start by checking your name on the domain name search page.

THNIC opens second-level .th names for registration in three rounds a year. The 2026 calendar is:

• Round 1: 1 February – 31 March 2026
• Round 2: 3 June – 31 July 2026
• Round 3: 1 October – 30 November 2026

In round 3/2026 applications open at 09:00 Thai time on 1 October 2026 and close at midnight on 30 November 2026. The shortlist follows on 1 December and the approved names on 15 December 2026; objections are accepted from 15 December 2026 to 15 January 2027. Orders placed outside a round are prepared for the next one.

Yes, if you own a trademark. THNIC recognises two routes for foreign applicants:

• Trademark registered in Thailand: apply with a mark registered at Thailand's Department of Intellectual Property (DIP); this route carries first priority in a contest.
• Trademark registered abroad: apply with a mark registered in your home country or elsewhere, through an authorised agent in Thailand; this route ranks second.

If you have no company or agent in Thailand, our trustee service covers the local representation. The SLD.th guideline does not list foreigners without a trademark among eligible applicants.

.co.th is a third-level category under .th, intended for commercial businesses and trademarks; it is open for registration at all times and applications are handled in order of arrival. .th is the second level itself: it opens only in application rounds, goes through committee approval and counts as a premium domain name under THNIC's policy. If your address needs to go live straight away, .co.th domain registration is the faster route. Holding the same name under .co.th also gives you third-place priority in a .th contest, so planning both names together makes sense.

No. Under the SLD.th guideline the name must be the English name of an organisation, a trademark or a natural person. An organisation may use its full name, an abbreviation or part of its name, but reordering it or adding letters or digits is not allowed. A name based on a trademark must match the mark exactly, letter for letter and digit for digit.

Only English letters, digits and hyphens are allowed, and a hyphen may not open or close the name or appear twice in a row. Community and geographic names, public names such as parks or natural resources, names of Thailand's core industries and culture, and names that sound like existing .th names are referred to experts, so their review can take longer.

Eligible applications within a round are assessed together, and priority is given in this order (THNIC policy clause 20.2):

1. The owner of a trademark registered with Thailand's Department of Intellectual Property
2. The owner of a trademark registered abroad applying through an authorised agent in Thailand
3. The holder of the same name at third level (except .in.th)
4. Other Thai citizens and entities under Thai law

If rights are equal, the committee may choose the application that benefits the Thai internet community most or auction the name (clause 20.3). Applying on the first or the last day of the round makes no difference.

Yes. Under clause 4.5 of the SLD.th guideline, each .th name also entitles you to register one .ไทย name, and THNIC's policy defines these as complementary domain names matched one-to-one with .th. The Thai name must be consistent with your English name in transliteration, pronunciation or meaning, judged against the principles of Thailand's Royal Academy. A Thai-script address lets users who type in Thai reach your brand directly.

Yes. A party that wants to contest an evaluation result files a petition on the registrar's website within the set period, together with evidence of its rights (THNIC policy clause 21). The registrar forms a panel of qualified experts within 30 days of the petition deadline, and the outcome is published on the same website. For round 3/2026, objections are accepted from 15 December 2026 to 15 January 2027.

Only in the cases listed in clause 13 of THNIC's policy:

• When ownership of the registered trademark changes
• When a company undergoes a merger, acquisition or similar change in legal status
• When a foreign holder replaces its authorised agent in Thailand
• When the holder dies or is declared legally incapacitated by a court

The registrar decides any other request at its discretion, with protection of the current holder as the priority. A .th name is therefore not an asset you can buy and sell freely.
