Quick answer
A registered office change is both an ACRA filing and an operational transfer. The new address must be in Singapore and accessible during the required business hours, while the company must update ACRA within 14 days and ensure government mail, legal notices and statutory records move without interruption.
- The registered office is the official location for communications, notices, records and registers.
- ACRA requires a Singapore address that is open and accessible during normal business hours.
- ACRA information should be updated within 14 days of the change.
- Do not end the old mail service before the new address and filing are ready.
- Reconcile mail, records, website, invoices, banks and licences after the change.
What the registered office is used for
The registered office is not merely an address printed on the business profile. ACRA and other parties use it to send communications and notices, and company records and registers may be kept there. A legal document delivered to the registered office can matter even if the directors work overseas or the business operates elsewhere.
The registered office does not have to be the same place as the company’s factory, shop or working office. It must, however, satisfy ACRA’s address and accessibility requirements and be able to handle official communications reliably.
Requirements for the new address
| Area | What to check | Why it matters |
|---|---|---|
| Location | A physical Singapore address, not an overseas address. | The registered office must be in Singapore. |
| Accessibility | Open and accessible during normal business hours on business days. | Allows public access and delivery of legal papers. |
| Office hours | ACRA guidance refers to at least three hours on each business day. | Non-compliance can create an offence risk. |
| Mail handling | Clear process for scanning, forwarding and urgent notices. | Directors need timely access to official correspondence. |
| Record storage | Ability to keep required company records or arrange compliant storage. | Registered office is a recognised location for records and registers. |
| Provider authority | Written service agreement and accurate unit details. | Avoids using an address without valid permission. |
Plan the effective date and 14-day update
ACRA states that changes to registered office address or office hours should be updated within 14 days. Choose an effective date that matches the service start date and corporate approval. Do not file an address that is not yet operational or continue showing an address after the right to use it has ended.
Prepare the board approval or internal authorisation, new address details, office hours and provider confirmation before the effective date. After filing, obtain the acknowledgement and updated business profile. Check the postal code, building, unit and office-hour information carefully.
Mail and notice migration
Keep the old address service active long enough to capture mail already in transit. Ask the outgoing provider for a final mail log and immediate release of government, legal, banking and tax correspondence. Give the new provider escalation rules for court documents, ACRA letters, IRAS notices and bank mail.
For overseas directors, agree how quickly items will be scanned and who monitors them. A monthly forwarding cycle is not suitable for a notice with a seven-day response period. The company should control the contact email and keep an archive of received correspondence.
Other places that may need updating
Review these records and counterparties
- Bank and payment-provider KYC records.
- IRAS, GST and CPF correspondence details where separately maintained.
- Invoices, quotations, contracts and purchase orders.
- Website footer, email signature and privacy notices.
- Licences, permits, landlords, insurers and key customers.
- Company registers, minute book and location stated in internal policies.
- Google Business or marketing listings only where the address is legitimately used for that purpose.
Not every system updates automatically from ACRA. Treat the business profile as the authoritative public record, then work through a controlled secondary update list.
Common mistakes
Common errors include using a mailbox that cannot receive legal papers, filing the provider’s general address without the correct unit, ending the old service too early, failing to retrieve statutory records, and assuming the registered office can be a P.O. box. Another mistake is treating mail forwarding as optional even though directors are overseas.
Where the company changes both secretary and address, coordinate the filings and transfer. Otherwise, the outgoing provider may still receive mail while the incoming secretary assumes the address already moved.

Due diligence on a registered office provider
Before choosing a provider, check whether the address is genuinely available for use, how many days mail is retained, whether original documents can be collected, and how urgent or registered mail is escalated. Ask whether the service includes a dedicated unit, shared address, mail forwarding, scanning limits and storage of company registers.
A very low fee can be reasonable for a basic address, but the company should understand what is excluded. Charges may apply for each scan, parcel, courier, government letter or physical inspection. More importantly, a provider that cannot reliably identify the company’s mail can expose directors to missed notices.
Keep evidence of the right to use the address, the service period and the person authorised to collect mail. Banks and regulators may ask for the relationship between the company and the address, particularly where no operating staff are based there.
