The .lk extension is the country-code domain of Sri Lanka, an island nation off the southern tip of India. Sinhala and Tamil are the official languages, and English is widely used in business and tourism. Tea estates, hotels, craft workshops and local companies use .lk to show a clear link to the island. Use the availability form just below this text to see whether your name in .lk is still available.

A short history
The national code has been used for many years by government bodies, universities and businesses. As the island's tea, tourism and export sectors grew, more companies and organisations began to use the zone for their websites. Sri Lanka has a long history of trade, and its ports and markets have linked it with other parts of Asia and beyond.
Who runs it
The .lk zone is managed by a national registry that keeps the database and sets the rules for registration. Registrars sell names to customers and send orders to the registry. The terms are set nationally, so read the current conditions before you order, and keep the holder data up to date.
Rules in practice
- Who may register: the registry may set conditions on who can hold a .lk name, so check your situation first.
- Holder details: the information must be accurate, and the registry may ask for proof of it.
- Characters: names use letters, digits and hyphens, within the length rules that apply.
- Renewal: enable automatic renewal, since a lapsed name can be taken by another party.
Who uses .lk
- Tea producers, exporters and brands that present their products to buyers around the world.
- Hotels, villas and tour operators that welcome visitors to beaches, national parks and the cultural triangle.
- Craft workshops, spice sellers and food producers, including cinnamon growers.
- IT services and software companies that serve clients in Sri Lanka and abroad.
Strengths
- The ending links a site to Sri Lanka at a glance, which helps local customers recognise it.
- English is widely used alongside Sinhala and Tamil, so a site can reach a broad audience.
- A name linked to tea, spices or the island's landscapes can tell a clear story in one word.
Things to keep in mind
- The zone is tied to one country, so a business with international customers may also want a generic address.
- Names built on popular place words are often taken, so combine a place with a service word.
- Visitors abroad may not know the ending, so display it clearly on packaging and cards.
- Registry rules can change, so check them before each renewal.
Tips before you register
- Check the name in .com and in the marketplaces where you sell.
- Enter the holder's details exactly as they appear in official records.
- Publish English content, and add Sinhala or Tamil pages if your customers use them.
- Set up SPF, DKIM and DMARC records before the domain sends invoices or newsletters.
- Turn on auto-renewal and keep a second trusted person with access to the account.
