The PRA and the Financial Conduct Authority (FCA) use six and seven-digit Firm Reference Numbers (FRNs) to uniquely identify firms, and six and seven-digit Product Reference Numbers (PRNs) to identify funds. The FCA issued the first seven-digit reference numbers on Tuesday 18 July 2023.
In June 2022, the FCA announced its plan to move to seven-digit FRNs and PRNs for newly registered firms and funds respectively. Firms and funds previously allocated six-digit references FRN or PRN will continue to maintain those numbers.
