.hk domain — Hong Kong's country-code extension, rules and how to register

What does .hk mean?

The .hk extension is the country-code top-level domain for Hong Kong. The two letters are Hong Kong's ISO 3166-1 code, HK — Hong Kong is a special administrative region with its own delegated ccTLD, separate from mainland China's .cn. It was delegated in 1990, early in Asia's internet history.

The namespace is managed by HKIRC, the Hong Kong Internet Registration Corporation, the non-profit body responsible for the territory's domains. For a city that markets itself as a global financial and trading hub, a .hk address carries a distinct meaning: it says a business is rooted in Hong Kong while still speaking to an international audience.

Who uses .hk?

A wide commercial and institutional mix. Hong Kong banks, trading firms, retailers, logistics companies, media and public bodies use .hk, and it reads as the credible local marker in a market where trust and provenance matter. Because Hong Kong is so internationally connected, plenty of foreign companies with a presence in the city also register a .hk to anchor their local operations.

Hong Kong offers both a direct second-level name.hk and a set of third-level category options — most visibly com.hk for commercial entities and org.hk for organizations, alongside reserved categories such as gov.hk and edu.hk. Commercial registrants frequently choose com.hk, much as a UK firm reaches for co.uk, while the shorter direct .hk is the most flexible choice.

.hk registration rules and requirements

The direct second-level .hk is open to anyone, anywhere — there is no residency or local-presence requirement for a standard registration, so a company outside Hong Kong can register one freely. That openness is a deliberate reflection of Hong Kong's role as an international business gateway.

The nuance lies in the category sub-spaces. Some third-level options carry their own expectations — gov.hk and edu.hk are reserved for government and education, for instance — while com.hk and org.hk are broadly available. For most businesses the practical choice is simply whether to take the clean direct .hk or the more conventional com.hk; both are administered by HKIRC under the same registry.

How much does a .hk cost?

Plan on roughly $20 per year at a mainstream registrar — a little dearer than many European country domains. As with other ccTLDs, the national registry shapes the pricing rather than open wholesale competition, so the spread between providers stays fairly narrow.

Is .hk good for SEO?

For the Hong Kong market, yes. Google and Bing read a ccTLD like .hk as a geo-targeting signal that a site is intended for users in Hong Kong, which can help local visibility in a way a generic .com does not provide automatically. The trade-off is reach: a country domain narrows your perceived audience to Hong Kong, so a brand pursuing a broad Asian or global market may still want a .com as its primary identity. When that balance matters to you, our TLD comparison guide sets it out clearly.

.hk vs alternatives

For a Hong Kong audience, .hk is the natural choice and signals local presence better than a generic. The main alternatives are .com for a borderless brand and the category form com.hk when a more traditional commercial look is preferred. Mainland-facing businesses sometimes look to China's .cn instead, but Hong Kong's distinct status means .hk is its own marker. Compared with restricted European ccTLDs such as Italy's .it, the open and internationally minded .hk is one of the easier Asian country domains for a foreign company to acquire.
