Registering a .sg or .com.sg domain: what Singapore businesses get wrong
Most Singapore companies register a .com without thinking about it, the way you might register a business phone number, and then add a .com.sg a year or two later because a customer asked or somebody noticed it was still free.
That second registration is where the trouble usually starts, because the national namespace does not behave the way the generic ones do, and almost nobody reads the terms when they buy a domain name for a hundred dollars.
Who is actually in charge
Singapore’s .sg namespace is run by SGNIC, the Singapore Network Information Centre. SGNIC is the registry. They set the rules about who may hold a name and under what conditions, and they do not sell to the public. You buy through an accredited registrar or one of their resellers.
That distinction sounds like trivia until something goes wrong. A question about eligibility or ownership gets resolved against the registry’s rules, not against whatever the support agent at your registrar told you over chat. Knowing which organisation is which saves a certain amount of frustration later.
They are not just different spellings
The most common misunderstanding I run into is people treating the .sg family as a menu of interchangeable options where you pick whichever one looks best on a business card.
They are not interchangeable. Several carry eligibility conditions, and the one almost every business actually wants, .com.sg, is intended for commercial entities registered here. SGNIC publishes the full breakdown in its category and eligibility rules, which is worth five minutes before you register anything.
In practice that means the registration is tied to a real, locally registered business, and the registry expects that relationship to hold for as long as you hold the name. A local company applying for a .com.sg has to supply a valid ACRA business registration number such as a Unique Entity Number (UEN), so the registry can verify the corporate status behind the name. Somebody has actually checked that there is a company on the other end.
Compare that to a .com, which anyone can register from anywhere, under any name, with no proof of anything at all. These are genuinely different kinds of asset, and the difference stays invisible until the day you try to transfer one, or discover that the entity it was registered against was struck off in 2019.
Four ways it goes wrong
In my experience the failures here are almost never technical. They are administrative, and they are boring, which is exactly why nobody catches them.
The name gets registered against the wrong entity. A director’s personal details, a holding company that has since been dissolved, or the web agency’s own company. It looks fine for years. Then there is a restructuring, or the agency relationship ends, and the name turns out not to belong to the business that depends on it.
The registrant contact is somebody who left. A .com.sg carries an ongoing relationship with the registry, and the registry talks to you through the contacts on file. Point those at a departed employee’s mailbox and notices about renewals or eligibility disappear into nothing.
Nobody knows which registrar holds it. Companies routinely hold the .com and the .com.sg of the same brand at two different providers, bought four years apart, with separate logins and separate billing. Neither is being watched. The renewal notices for both go somewhere nobody reads.
And underneath all three: the registration gets treated as a purchase rather than an obligation. It is not a thing you bought. It is a thing you are responsible for, with a date attached and conditions on the back.
What a healthy one looks like
Four properties, none of them technically demanding.
The registrant is your company, named exactly as ACRA has it. The contacts on file are people who currently work for you, and there is more than one. You know which registrar holds the name and you can log in. The renewal date exists somewhere a human being will look at before it arrives.
That is the whole list. It is not difficult work. It is simply work that has not been assigned to anybody, which is why it stays undone until it becomes urgent, and urgent domain problems are considerably more expensive than routine ones.
If you genuinely don’t know
Most companies we start working with cannot tell me from memory which domain names they own, whose name they are in, or when they expire. That is not a criticism, it is just what happens when a job belongs to nobody in particular. I would rather someone say “I have no idea” than guess.
Finding out is quick and it does not cost anything. Securlogic will look at what is actually registered against your company, who the registrant of record is, and what state the configuration is in, then tell you what needs attention. Whether you do anything about it afterwards is up to you.
Eligibility rules for the .sg namespace are set by SGNIC and change from time to time. Confirm the current requirements against SGNIC’s category and eligibility rules, or ask us, before making decisions about a specific registration.
Not sure what your company actually holds?
We will check what is registered against your company, who it is registered to, and what condition it is in. Written in plain English, with no obligation.
