What is a Conveyance Reference Number (CRN)?

A Conveyance Reference Number (CRN) identifies a Highway Conveyance Document and provides information about the vehicle being used to transport goods entering Canada. The CRN is a unique reference number that can be up to 25 characters and contain both numbers and letters assigned by the carrier to a particular trip or departure. The CRN must begin with the CBSA-issued Carrier Code (already hard-coded in the field).
