Unique Business Identifier (UBI) refers to the first 8 digits of a Hong Kong company’s Business Registration Number. Starting from December 27, 2023, the Companies Registry has replaced the Company Registration Number (CI number) with the Business Registration Number to uniformly identify limited companies.
The Unique Business Identifier applies to the following types of companies:
1. Companies formed or registered under the Companies Ordinance (Cap. 622)
2. Open-ended fund companies formed or registered under Part IVA of the Securities and Futures Ordinance (Cap. 571)
3. Limited partnerships registered under the Limited Partnerships Ordinance (Cap. 37)
4. Registered trustee corporations formed under the Registered Trustees Incorporation Ordinance (Cap. 306)
5. Other companies or entities formed or registered under other Ordinances administered by the Registrar of Companies

Is the Business Registration Number the same as the Company Number?
For companies newly incorporated from December 27, 2023, the Company Number is the same as the Business Registration Number, which is the Unique Business Identifier.
However, for limited companies incorporated before December 22, 2023, the Company Number on the Certificate of Incorporation is not the Business Registration Number.
How can I confirm if my Certificate of Incorporation number is the Unique Business Identifier?
If the date of issue of the Certificate of Incorporation (i.e., the date of incorporation) is on or after December 27, 2023, the Company Registration Number will be 8 digits and will be the same as the Business Registration Number.
If the date of incorporation is on or before December 22, 2023, the Company Registration Number has only 7 digits. You must use the first 8 digits of the Business Registration Number to replace the Company Registration Number.
Revamped Companies Registry Website and Integrated Information System
As the Business Registration Number and Company Number have been unified into the first 8 digits of the BRN, the Companies Registry also revamped the Companies Registry Electronic Services Portal and the Integrated Information System on December 27, 2023. Users can use the Unique Business Identifier for the following functions:
1. One-stop service: log in once to submit forms online and conduct electronic searches
2. Pay fees and apply for services with a single user account
3. Responsive web interface compatible with desktop or mobile display sizes
4. New dedicated pages for users who frequently register companies
5. Ability to modify previously saved online e-forms before submission
6. Compatible search function: users can still use the old Company Number to search for limited company information
7. Option to apply to use a correspondence address and identification number instead of registered information at the Companies Registry
