The .sl extension is the country-code domain of Sierra Leone, a country on the Atlantic coast of West Africa, between Guinea and Liberia. Businesses, schools, health services and community groups that work with people in the country use it to show a local presence. English is the official language, and Krio is widely spoken in everyday life, so local sites may use either. Try the availability form under this text to see whether your name in .sl is still available.

A short history
The national code was assigned when Sierra Leone joined the global internet. In its early years the zone was used mostly by institutions and early online services. It later spread to businesses, media outlets and development organisations, and today it is part of the everyday online life of many organisations in the country, from small shops to larger institutions.
Who runs it
The .sl zone is managed by a national registry, which keeps the database of names and sets the conditions for registration. Accredited registrars sell names and pass orders to the registry. Because the rules are published by the national body, check the current conditions for holders, contact data and renewal before you order, since they can change over time.
Rules in practice
- Holder conditions: the registry may set rules on who can register a .sl name, so confirm that you qualify before you pay.
- Contact data: the holder information must be correct and up to date, and the registry may check it.
- Name format: names use letters, digits and hyphens, subject to the registry's length rules.
- Renewal: enable automatic renewal and keep the expiry date visible to the people who run the site.
Who uses .sl
- Shops, hotels and restaurants that serve customers in Sierra Leone.
- Schools, training centres and youth groups that publish notices and programmes.
- Health clinics, pharmacies and professional services that want a local address.
- Media outlets, churches and community associations with a Sierra Leonean audience.
Strengths
- The ending gives a clear signal that the site is connected with Sierra Leone, and local visitors recognise it at once.
- Search engines may treat a country-code ending as one signal of the audience, which can help local-language content.
- The two-letter ending is short and simple to share on a phone, a poster or a shop front.
Things to keep in mind
- A .sl name speaks to one country, so a service with customers abroad may also want a generic address.
- Visitors from elsewhere may not know the ending, so show the full address clearly on every page and document.
- Descriptive names are often taken, so combine a service word with a place name where it fits.
- The rules may change, so review the terms before you renew or transfer the name.
Tips before you register
- See whether the same name is available in .com and decide whether the second address is useful.
- Enter the organisation's details exactly as they appear in its official registration documents.
- Write pages in English, Krio or both, depending on the readers you expect.
- Add SPF, DKIM and DMARC records before the domain sends e-mail or invoices.
- Keep the registrar login protected and give a second trusted person access to the account.
Frequently asked questions
Can someone outside Sierra Leone register a .sl name? The answer depends on the rules in force, so look up the current conditions before you order.
Does .sl help a site show up in local search? It adds a useful geographic hint, but clear content, a fast site and reliable links usually matter more.
Can I write a .sl site in Krio? Yes. The ending does not set the language, so Krio, English or both can work well for a local audience.
