How can I know the Business Registration Number (“BRN”) of a company / an entity on or after 27 December 2023 if I have got the CR number only?

Upon the implementation of the second phase of Unique Business Identifier, searcher can look up the corresponding BRN of a company / an entity by the existing Company Number / CR Number / Company Registration Number and vice versa by using the “Quick Search > CR No. / BRN Mapping” function of the Electronic Search Services of the Companies Registry.
