Common mistake 1 with set up a registered office address

Using a PO box or an unstaffed virtual mailbox — it has to be open to the public at least 3 hours on each business day, not just able to receive mail.

Common mistake 2 with set up a registered office address

Using a home address without checking it becomes publicly searchable on ACRA's register — use a registered filing agent's address instead if you want privacy.

Common mistake 3 with set up a registered office address

Forgetting to update the address with ACRA when you move — correspondence keeps going to the old address until you file the change, it doesn't update automatically.

Ready Steady Rules

Set up a registered office address

Every company needs a registered office address in Singapore — the address ACRA holds on public record and where statutory notices and correspondence are sent.

Every company needs a registered office address in Singapore — the address ACRA holds on public record and where statutory notices and correspondence are sent. It must be open to the public for at least 3 hours on each business day, and it cannot be a PO box. It can be your business premises, an approved home-office arrangement, or a registered filing agent's address.

ACRA won't register or maintain your company without a valid registered office, and it's where legal notices are deemed served — miss one because the address wasn't staffed or reachable, and you can't claim you never received it.

WHEN

Can be arranged same day — an address only becomes "registered" once you file it with ACRA

COST

Free if you use your own premises. A commercial registered-office or virtual-office service costs a market rate that varies by provider
