.sg Domain: Singapore's Official Country Extension
.sg is the country code top-level domain (ccTLD) of Singapore, entered into the root zone on 19 October 1988. The zone is operated by Singapore Network Information Centre (SGNIC) Pte Ltd. SGNIC describes its role as providing internet registry and information services to enhance the security, stability and resiliency of the domain name system infrastructure in Singapore, and it collects the registration framework in seven separate documents.
In the category rules .sg is the broadest zone: in SGNIC's own words all persons may apply in this category, but a foreign applicant must appoint and duly authorise a local agent as its administrative contact. If you do not want to be tied to a particular institutional status, .sg is therefore the most flexible option. If you want the address to state a business registration as well, .com.sg is the commercial zone of the same scheme and rests on an ACRA or Enterprise Singapore record.
One further step follows registration: VerifiedID@SG. SGNIC states that its purpose is to mitigate the use of fake identity information associated with a .sg registration and to enhance trust in .sg websites. Verification is carried out by the administrative contact, within 21 calendar days from the date of registration, with a one-time seven-day extension available through the portal. Check the name you have in mind with domain search.

.sg Domain Lifecycle
What happens day by day after it expires
Day 0 is the domain's expiry dateIn short: for .sg the post-expiry timeline is set by the registry, so it differs from one extension to the next. The diagram below shows the windows that actually apply to .sg, day by day. One thing never changes, whichever extension you hold: renewing before the expiry date is always the cheapest and safest route.
Domain Is Available (Available)
A .sg address at this stage has not been taken yet, and it goes to whoever registers first. Check the name you have in mind — if it is free, it can be yours within minutes.
Domain Is Active (Active Period)
Once registration is complete, the domain is registered to you for the term you selected. You can renew at any point before it expires to keep it active, or switch on auto-renewal so you never have to watch the date.
Redemption Period (Redemption Period)
The domain is not released the moment it expires — during this window it is still yours and can be recovered. Some extensions charge an extra restore fee at this stage, so renewing before expiry is always the cheaper route.
Domain Is Available Again
Once deletion completes, the domain leaves the system and anyone can register it — popular names are often taken the same minute by someone watching. Keep auto-renewal on so a name you care about never gets this far.

Frequently Asked Questions About .sg Domains
The questions people actually ask before registering — answered plainly.
-
SGNIC's category rules make .sg the broadest zone: all persons may apply in this category. The only condition falls on applicants from abroad — they must appoint and duly authorise a local agent in Singapore as their administrative contact. If you want a Singapore address without being tied to a particular institutional registration, this is the zone; for an address that also states a business registration there is .com.sg.
-
VerifiedID@SG is SGNIC's mandatory identity verification; its stated purpose is to mitigate the use of fake identity information associated with a .sg registration and to enhance trust in .sg websites. It is carried out by the administrative contact of the domain name, who verifies the identity and contact information of the registrant. Every .sg name registered from 2 May 2013 onward is covered, as are older names whose registrant or administrative contact details change.
-
The administrative contact has 21 calendar days from the date of registration to complete verification, with a one-time seven-day extension available through the portal. Miss the window and the new domain stays suspended — in SGNIC's words, its website and emails will cease to function. An unverified name also cannot be renewed. This step therefore decides whether the address works at all, rather than being a piece of administration.
-
Yes, on one condition: the category rule requires a foreign applicant to appoint and duly authorise a local agent in Singapore as its administrative contact. The VerifiedID@SG page adds that every administrative contact must maintain a local presence and a valid Singapore postal address. Foreign applicants without Singpass or Corppass may, in exceptional circumstances, ask their administrative contact to apply for an 'SGNICID'.
-
Verification uses Singpass for individuals with a Singapore NRIC or FIN, and Corppass for organisations with a UEN; SGNIC puts the process at under five minutes. The administrative contact signs in to the VerifiedID@SG portal and confirms the registrant's identity and contact details. For foreign applicants who hold neither credential, the SGNICID is defined as an exceptional route.
-
SGNIC separates the categories by purpose:
- .sg — open to all persons
- .com.sg — businesses registered with ACRA, Enterprise Singapore or a professional body
- .org.sg — bodies registered with the Registry of Societies, plus town councils, community centres, places of worship and embassies
- .edu.sg — educational institutions only
- .gov.sg — government bodies only
- .net.sg — IMDA licensees and network-based hosting providers
-
In SGNIC's own words, the term options for a new registration are 1 year, 2 years and 3 years. The same options apply on renewal, provided the expiry date after renewal does not exceed three years from the date SGNIC receives the instruction. Bear in mind too that an unverified domain cannot be renewed: making a long-term plan before VerifiedID@SG is complete buys you nothing.
-
You can see whether a .sg name is registered, and the general state of the record, through WHOIS; SGNIC governs this area with a separate WHOIS/RDAP policy. A lookup will usually show the status of the name and its registration dates, while contact details are published only in limited form. Run the lookup on the whois search page, and check whether a name is free with domain search.
