There are two login screens for broadcasters at https://stationaccess.fcc.gov. The first, Facility Sign In, accepts a facility and passcode to manage a single station’s Public Inspection File. The second, FRN Sign In, allows the FRN holder to use their primary FRN and associated password to see their stations’ facility ids and associated passcodes and to track the history of each station’s Public Inspection File. There is a link on the Facility Sign In to switch to the
FRN Sign In screen. The primary FRN is the FRN you have used to pay fees and file other applications with CDBS.
