NICB has a mirror image of NCIC's stolen vehicle file. Every stolen vehicle entered on NCIC will be passed to NICB by NCIC. NICB will enter this record on their file and interrogate Impound (last 60 days entries), Export, Auction and International Index Files. If a VIN match is made, the following message will be forwarded via NLETS ("AM" message) to the entering agency:
"THIS IS TO NOTIFY YOU THAT THE VEHICLE YOU ENTERED INTO NCIC, VIN/12345671234567890, IS IN THE NICB DATABASE. BELOW IS THE NICB RELATED VEHICLE RECORD. THIS MAY ASSIST YOU WITH ANY FOLLOW UP INVESTIGATION. (followed by matching NICB record)
