Domain Name Guide for Singapore: .sg vs .com.sg vs .com

For a Singapore business, .sg or .com.sg tells customers you are local, while .com is the familiar default that many people type first. Whichever you pick, register it through an accredited registrar, in your own business name, with your own login. That one habit protects you more than the extension does.

What a domain name is, and what it is not

A domain is your address on the internet, such as yourbusiness.com.sg. It is separate from your website and your hosting. You can change your website provider and keep your domain, if the domain is in your name.

A domain is also usually the base for your business email, so changing it later affects both your site and your inbox. Pick one you can live with for years.

.sg vs .com.sg vs .com

Which one should you actually use?

If your customers are in Singapore, a .sg or .com.sg builds local trust. If you also have the .com, point it to your main site so people who type it by habit still reach you. If you cannot get your .com, do not twist the name into something awkward. Pick a better name and a clean extension instead.

Choose a name that works

A good domain is easy to say over WhatsApp, a phone call or a taxi ride.

Keyword-heavy names rarely help and often look spammy. Your pages, reviews and profile do the work of matching searches. See the local SEO checklist.

How to register a domain

Domains are sold through registrars, and for .sg they need to be accredited with SGNIC. You can choose a registrar you trust, compare their renewal terms, and register for one or more years.

Whose name goes on it?

The registrant is the legal owner of the domain. Make it your company or yourself, not your web designer. Many owners learn this the hard way when a freelancer disappears and the domain is stuck in their account.

If someone else registers it on your behalf, ask for the registrant record to show your business and for the account to be transferred or shared with you. Our guide on who owns your website goes deeper.

Renewal: the quiet way people lose domains

Domains are rented for a set period. If you miss the renewal, the domain can expire, the website and email stop working and, eventually, someone else may be able to register it.

Renewal prices can differ from the first-year price, so read the terms before you buy. Ask your registrar what the ongoing renewal will be, and check it each year.

Privacy, transfers and locks

Contact privacy

Domain registration involves contact details. Some registrars offer ways to limit what is publicly visible. Ask what is shown and what options exist, and check current SGNIC and registrar policies for .sg.

Transfers

You can usually move a domain to another registrar if you want better service. You will need an authorisation code and the domain must be unlocked. Keep your contact email current, or you may not receive the confirmation.

Registrar lock

A lock stops unauthorised transfers. Leave it on, and only unlock when you have a planned move.

Domain and business email

An address like hello@yourbusiness.com.sg looks more established than a free webmail address, and it travels with you if you change providers. Set it up with an email host, add the records they give you at your domain's DNS settings and test sending and receiving.

Take care when editing DNS. A wrong record can take your website or email offline. If you are not sure, ask your provider to make the change and tell you what was done.

A worked scenario: the new cleaning company

Hafiz starts a home cleaning business and wants hafizcleaning.sg, but his cousin offers to buy a domain "for free" through his own account. Hafiz thanks him, then registers it himself with a registrar, in the company name, using a business email and 2FA.

He also registers the .com version and sets it to point to the main site. He adds a calendar reminder, turns on auto-renew and puts the login in his password manager. Two years later, when he changes web provider, nothing about his address changes. That is the whole point.

A naming test you can run in ten minutes

Before you pay for anything, run your shortlist through a few quick checks. It is much cheaper to drop a name now than to rebrand later.

More Singapore examples

The tuition teacher with a common name

Priya Tan wants priyatan.com.sg, but there are many people with similar names, and the name says nothing about what she does. She picks a name based on her subject and level, checks it is easy to say, and registers the .sg and .com.sg versions only if both pass SGNIC's rules and the cost makes sense. She points the extra one to the main site so nobody lands on an error page.

The multi-service handyman

A handyman offers aircon servicing, plumbing and electrical fixes. If he builds the name around one service, he boxes himself in. A name based on his own brand leaves room to add services and still works when he says it on the phone.

The family firm that inherits an old domain

A trading company finds its domain is registered under a former employee's personal email. The owner contacts the registrar, follows its process to prove the business's connection to the domain, and updates the registrant and contact details. It takes time and paperwork, and it is much easier when the records are right from the start.

Troubleshooting: when something does not work

• The site does not load after connecting the domain: DNS changes can take some time to spread. Check that the records match exactly what your provider gave you, and wait before changing them again.
• Email stopped after a site move: the mail records may have been overwritten when the website records were changed. Compare the records with your email host's instructions.
• The registrar says the domain is locked: that is normal. Unlock it only when you are ready to transfer.
• You do not receive the transfer email: the contact email on the record may be old. Update it with your registrar before trying again.
• A warning that your domain is about to expire: check that it came from your registrar before paying. Fake renewal notices are a known trick, so log in to the registrar directly.
• The www version and the plain version show different pages: ask your provider to redirect one to the other so visitors and search engines see a single address.

Choosing under uncertainty

If you are torn, use this rule of thumb. Pick the name you would be happy to print on a van, then pick the extension that your customers are most likely to type, and own the others only if you can afford to. Keep notes of why you chose what you did, so whoever manages the site in future understands the decision.

Common mistakes

• Letting an agency or friend register the domain under their own name.
• Using a personal email that may stop working.
• Choosing a name that is hard to spell or too similar to a competitor.
• Skipping auto-renew and missing the date.
• Editing DNS records without knowing what they do.

Your next step

Check availability for your top two names, read the current rules at sgnic.sg and register through an accredited registrar in your own name. Then hand the details to whoever builds your site. See what Website.sg includes (the plan does not include buying the domain, so you will register that yourself). Next, read who owns your website, the hosting guide and the website launch checklist.
