The .lk top-level domain is the country-code domain for Sri Lanka, managed by the Council for Information Technology. Originally delegated in 1990, it is used by businesses, educational institutions, government entities, and individuals within Sri Lanka or with a connection to the country. While primarily serving local registered entities, it also allows international organizations to register domains under open second-level categories like .com.lk and .org.lk.
Domains are primarily registered to organizations such as statutory bodies, corporations, firms, and associations. Individuals may register under certain conditions, such as using their personal name for professional or artistic purposes. Certain second-level domains are restricted to specific entities (e.g., .gov.lk for government, .ac.lk for universities, .sch.lk for schools). Names that imply governmental affiliation, contain trademarks without authorization, or are offensive or misleading are prohibited.
The .lk extension is a country-code top-level domain (ccTLD) in the Domain Name System (DNS). It is managed by Council for Information Technology, LK Domain Registrar. .lk was introduced in 1990.
Registration pricing for .lk is not publicly listed. Contact an ICANN-accredited registrar for availability and pricing.
The .lk domain was delegated on June 15, 1990, and has been administered since by the Council for Information Technology in Sri Lanka. It was established to support the digital presence of Sri Lankan institutions, organizations, and individuals. Over time, the registry has expanded access to international entities and introduced structured second-level domains for better categorization.
The .lk TLD serves a specific purpose in the domain ecosystem, providing users with clear context about the websites using this extension.
The .lk TLD is commonly used for the following purposes:
Applicants must provide valid identification and proof of eligibility. Organizations require incorporation documents; individuals must demonstrate professional use of their name. For restricted second-level domains (e.g., .gov.lk, .ac.lk), official authorization from the relevant Sri Lankan authority is required. All domains must comply with character rules: only letters, numbers, and hyphens allowed; no leading/trailing hyphens.
The .lk TLD is available for registration through accredited domain registrars.
