What is a Registered Office in Singapore? (2026)
The registered office is the official address of a Singapore company where notices and legal documents can be served — it must be a physical local address, open to the public for set hours.
What are the requirements for a registered office?
The registered office must be a physical location in Singapore. It must be open to the public for at least 3 hours during ordinary business hours on each business day. It is where the company keeps certain statutory registers and where official mail and legal documents are served. The minimum public-access hours are as commonly published; confirm the current requirement on ACRA before relying on the exact figure.
Can I use a service provider’s address?
Many companies — especially those without their own premises — use the registered office address provided by their corporate service provider. Any change to the registered office address must be notified to ACRA via Bizfile+.
