What information you need
If you are already authorised by us, you will need your Firm Reference Number (FRN) and Individual Reference Number (IRN). If you are a sole trader you will not have an IRN, but you can use a registration key – your key was sent to you in your firm’s authorisation letter.
You also need to know who your Connect Principal User will be for your firm. To register the Connect Principal User, you need to hold a Controlled Function (CF), Senior Manager Function (SMF) or a Senior Insurance Manager Function (SIMF) at the firm. They will need to provide their Individual Reference Number and National Insurance Number or Passport number to register as the Principal User.
