The .sd extension is the country-code domain of Sudan, a large country in northeast Africa with a coastline on the Red Sea. Companies, schools, media outlets and community groups that serve people in Sudan use it to show a local identity. The capital, Khartoum, stands where the Blue Nile and the White Nile meet. Start with the availability form below this paragraph to check whether your name in .sd is still available.

A short history
The national code was assigned as the country took its place on the global internet. For many years the zone was used mostly by universities, research centres and early internet services. As Arabic and English websites multiplied, local businesses, news outlets and institutions began to register names. Today the zone serves a wide range of organisations, from small shops and schools to larger companies and public bodies.
Who runs it
The zone is managed by a national registry, which keeps the central database and sets the rules for registration. Accredited registrars take orders from customers and pass them to the registry. Because the rules are set nationally, the current published policy is the one that applies, and it should be checked before you order.
Rules in practice
- Holder requirements: conditions on who may register a .sd name can apply, so check them before you pay.
- Accurate records: the contact and holder details must be correct, and the registry may ask you to confirm them.
- Name format: names are built from letters, digits and hyphens, following the registry's length rules.
- Renewal: enable automatic renewal and keep a second contact address on the account.
Who uses .sd
- Shops, trading firms and service providers that work with customers in Sudan.
- Schools, universities and training centres that publish courses and notices.
- Media outlets, cultural groups and local information sites.
- Foreign companies that serve Sudanese customers and want a clear address for that market.
Strengths
- The ending shows a clear link with Sudan, which local readers recognise straight away.
- Search engines may use the country-code ending as one signal of the intended audience, which can help local-language content.
- Arabic is the main language of many sites, and English is used by many organisations as well, so the zone suits content in either language.
Things to keep in mind
- The name points to one country, so an international service may also want a generic address.
- Visitors outside the country may not know the ending, so print the full address on every card and sign.
- Short and common words are often taken already, so a descriptive name may be easier to register.
- The registry may update its conditions, so check the current terms before any transfer.
Tips before you register
- Check whether the name is also open in .com and weigh the two options side by side.
- Use the organisation's name exactly as it appears in its registration papers.
- Write the site in Arabic, English or both, depending on the readers you want to reach.
- Publish a clear contact page and a privacy notice before the domain goes live.
- Set up SPF, DKIM and DMARC records before you send e-mail from the domain.
Frequently asked questions
Can an organisation outside Sudan register a .sd name? Holder conditions may apply, so check the current rules at the time of the order.
Does .sd help a site appear in local search results? It is one useful signal, but relevant content, fast pages and good links usually matter more.
Can I write a .sd site in Arabic? Yes. The ending does not set the language, and Arabic content is a natural match for many local readers.
