Display of Certificate
The valid business registration certificate/branch registration certificate must be displayed in a conspicuous place at the address where the business is carried on and should be produced for official inspection on demand. An inspector authorized by the Commissioner shall have power at all reasonable times to enter any premises at which he had reason to believe any business is being carried on and there to make such examination and inquiry as may be necessary.
Where business registration certificates are issued in electronic form under the one-stop company and business registration service, companies must display a printed copy of such certificates.
If you lost your business / branch registration certificate after payment, you can obtain a plain duplicate of a valid Business / Branch Registration Certificate of a business from the Business Registration Office. Application can be made via the website of GovHK : www.gov.hk/br (Online Application for Business Registration Documents) or by completing form IRBR 37, together with payment of the prescribed fee.
