The .sg extension is the country-code domain of Singapore, a small island city-state at the southern tip of the Malay Peninsula. Companies, schools and organisations that serve customers in Singapore use it to show a clear local base. English is widely used in business there, so a .sg address fits an English-language site as naturally as a local one. Use the availability form just below this text to see whether your name in .sg is still available.

A short history
Singapore received its national code in the early days of the internet, and the zone grew as the country's universities, government agencies and companies moved online. Over the years it became a familiar part of the Singaporean web, used by trading firms, logistics companies, schools, clinics and neighbourhood shops alike. The registration rules have been revised along the way, so the current terms are the ones that count when you order.
Who runs it
The zone is run by the registry designated for Singapore's country code, which keeps the database of names and sets the conditions for registration. Accredited registrars sell names to customers and pass the orders on. Because the conditions come from the registry itself, they are the reference point for questions about eligibility, contact details and renewal, and they can change over time.
Rules in practice
- Eligibility: conditions for holders can depend on their location and legal form, so check the current rules before you pay.
- Second-level zones: names under zones such as com.sg follow their own rules and are a separate choice from a plain .sg name.
- Contact details: the information you give must be accurate, and it may be checked when the registry asks for it.
- Characters and length: labels use letters, digits and hyphens, and can be up to 63 characters long.
Who uses .sg
- Trading companies, importers and logistics firms that serve the Singapore market.
- Restaurants, clinics, tuition centres and other local services across the city.
- Schools, professional associations and community groups with a Singapore audience.
- Regional businesses that want a clear Singapore base for their customers in the area.
Strengths
- The ending shows a Singapore base at a glance, which helps local customers trust a business they can find nearby.
- Search engines can read a country-code ending as one geographic hint, so Singapore-focused content may match local searches well.
- English, Malay, Mandarin Chinese and Tamil are the official languages, so a site can be written in the language its visitors use most.
Things to keep in mind
- The ending ties the site to Singapore, so a business whose customers are mostly overseas may also need a generic address.
- Good short names are often taken, so prepare two or three wording options before you start.
- Visitors from nearby countries may type .com out of habit, so decide early whether you need both.
- Conditions for holders can change, so check your registration data when the rules are updated.
Tips before you register
- Check the same name in .com and in the other zones you plan to use.
- Enter the holder and company details exactly as they appear in your official business records.
- Decide which languages the site will use and plan those pages before launch.
- Host the site close to Singapore visitors so that pages load quickly for them.
- Turn on auto-renewal and protect the registrar account with two-factor login.
Frequently asked questions
Do I need a company in Singapore to register .sg? The conditions depend on the holder and on the zone you choose, so read the current rules before you order.
Is .sg only for English-language sites? No. The ending points to Singapore, and the language is your choice. English is common in business there, but Chinese, Malay or Tamil content can also suit local visitors.
Does .sg help a site appear in Singapore search results? It is a useful geographic signal, but relevant local content, fast pages and genuine links usually carry more weight.
