.sg vs .com.sg: Domain Registration Rules in Singapore

Singapore domains are managed by SGNIC, and registering one usually requires a local connection. The two common choices are the open .sg and the business-oriented .com.sg. Here is how they compare and what you need.

.com.sg: for registered businesses

A .com.sg signals an established Singapore business. To register one you generally need a locally registered organisation, typically with an ACRA registration number. That requirement is part of why .com.sg reads as credible and commercial.

Have your ACRA registration details ready when you register.

.sg: broader local eligibility

The .sg extension is open more broadly to those with a Singapore presence, including individuals who can show a local connection. It is short, clean and clearly Singaporean, which makes it a strong choice for both businesses and personal brands based in Singapore.

Trust and search

A Singapore extension helps customers recognise you as local and helps search engines associate your site with Singapore. For a business serving the local market, that recognition matters. If you trade across the region or globally, you might pair it with a .com.

As always, the extension supports trust but does not replace good content and fast hosting.

Quick guidance

• Registered Singapore business: .com.sg carries commercial credibility (ACRA registration needed).
• Want a short local address: .sg is clean and clearly Singaporean.
• Serving the wider region: consider adding a .com.
• Whichever you pick, host it close to your audience and secure it with SSL.
