.th Domain: What It Is, How It Differs from .co.th, and Who Should Use It

What Is the .th Domain?

The .th domain is Thailand's Country Code Top-Level Domain (ccTLD) in its shortest form — no second-level segment like .co or .in between the brand name and the country code. The result is a URL like yourbrand.th instead of yourbrand.co.th.

Before October 2022, Thai internet users could only register second-level domains under .th — like .co.th for companies, .in.th for individuals, .ac.th for academic institutions, and .go.th for government agencies. THNIC (Thailand Network Information Center) changed this when it opened direct .th registrations for the first time in Thai internet history, allowing any verified Thai entity to claim a cleaner, shorter URL.

In brief: .th = Thailand's shortest domain. Launched 2022. Open to individuals and companies alike. Ideal for brands that want a concise, unmistakably Thai URL.

A Brief History — Why Did .th Take So Long?

When Thailand first connected to the global internet in the early 1990s, THNIC designed a structured second-level domain system to categorize users: .co.th for commercial entities, .ac.th for academia, .go.th for government, and so on. This system served Thailand well for over 30 years.

As the digital economy evolved, Thai entrepreneurs increasingly wanted shorter, more memorable URLs — particularly for marketing on billboards, radio, and TV, where every character in a URL matters. After extensive consultation, THNIC finally opened .th apex domain registrations in October 2022, with major Thai brands and institutions rushing to secure premium .th names during the Sunrise Period.

Context: Countries like Japan (.jp), South Korea (.kr), and Germany (.de) have used short apex ccTLDs for decades — they serve as proof that a clean, country-code-only domain strengthens brand recall, especially in offline media.

Documents Required to Register .th

The .th domain uses the same verification requirements as .co.th and .in.th. THNIC mandates identity verification to prevent misuse of Thai domains.

Company / Legal Entity

Important: The .th domain name you apply for must be related to the name or brand in your supporting documents. THNIC will reject unrelated names — e.g., a company called "ABC Co., Ltd." can register abc.th but not unrelatedword.th.

Five Advantages of .th Over .co.th

1. Shorter URL, Easier to Remember

Compare asiagb.th vs asiagb.co.th — that's 4 fewer characters. In a world of billboards, radio spots, and print ads where every character counts, the shorter form wins. Research on brand recall consistently shows that shorter URLs are remembered 20–30% better than longer alternatives, especially in offline media where users can't click a link.

2. Clear Thai Identity — Without Extra Words

Using .th instead of .co.th doesn't make your Thai identity less clear. If anything, it projects confidence: the brand needs no qualifier. Just as apple.com doesn't need apple.com.us, a Thai brand on .th signals it's established enough to claim the apex domain directly.

3. SEO — Equal Treatment from Google

Google treats .th and .co.th identically for geotargeting — both are automatically associated with Thailand. There is no documented evidence that .th performs better or worse than .co.th in Thai search rankings. The factors that matter far more are content quality, page speed, and backlink profile. That said, shorter, cleaner URLs can earn higher click-through rates in search results, which indirectly benefits SEO.

4. Better Name Availability

With .co.th having been open since the 1990s, most short, valuable names are long gone. The .th namespace opened in 2022 — prime one-word and two-word domains that would be taken on .co.th are more likely to be available on .th, giving newer brands a real chance at clean, premium URLs.

5. Future-Proofing Your Brand

As .th grows in recognition over the coming years — following the path of .jp, .de, and .kr — having secured your .th name early means you'll own it before competitors do. Early movers in national ccTLD adoption consistently report stronger brand equity as the domain gains public recognition.

Potential Drawbacks of .th

Lower Current Awareness Among Older Demographics

Since .th launched only in 2022, some internet users — particularly older demographics less exposed to new TLDs — may initially be unfamiliar or uncertain whether it's a valid domain. During the early adoption period, you may need to actively communicate your .th address in marketing materials more than you would with the well-established .co.th.

No Built-in Type Categorization

.co.th immediately signals "commercial company." .ac.th signals "academic." With .th, there's no such implicit category. For government agencies and academic institutions that use their second-level TLD for official credibility (.go.th, .ac.th), sticking with the sub-domain structure is still the better choice.

Who Should Register .th?

Who Should Stick with .co.th?

Best of both worlds: If both .th and .co.th are available for your desired name, register both and 301-redirect .th to .co.th (or vice versa). This prevents competitors or squatters from claiming the other and captures traffic from both URLs.

Migrating from .co.th to .th — SEO Checklist

If you already have a .co.th domain and want to switch to .th, follow this migration checklist to protect your search rankings:

Google officially confirms that properly implemented 301 redirects pass close to 100% of link equity, so a well-executed migration has minimal long-term SEO impact.

Frequently Asked Questions

Can I register .th without a company?

Yes. Thai individuals can register .th with just a copy of their national ID card, as long as the domain name relates to their name or personal brand.

Is .th better than .com for Thai audiences?

For targeting Thai users specifically, yes — .th and .co.th carry automatic geotargeting for Thailand in Google's eyes. .com has no built-in geotargeting (unless you set it manually in Search Console). If you serve both Thai and international audiences, consider using .com with proper hreflang setup.

If THNIC rejects my domain name, do I get a refund?

This depends on the registrar's policy. Generally, if the rejection is because the name doesn't meet THNIC's naming rules (not due to incomplete documents), the registrar will process a refund. AsiaGB recommends discussing your desired name with our team before ordering to confirm it's likely to pass review.

Does .th support IDN (Thai characters)?

Yes, THNIC supports Internationalized Domain Names (IDN) for .th — meaning domain names written in Thai script are technically registrable. However, Thai-script domains are used very rarely in practice due to compatibility issues with older software and cross-platform linking.
