Like cars, guns, boats, electronics and other important items, shipping containers have a serial number. The ISO 6346 Code (also known as the BIC-Code) is basically a unique serial number for every shipping container. It consists of four characters long ending in either U, J or Z, followed by six numbers and a check digit. It is the standard that’s used when a container is used for containerized intermodal freight transport and guarantees that the container is unique. It identifies the owner or principal operator of the container and once entered into the BIC international database permits the tracking of dimensions, type, year of putting into operation, date of control, maintenance records, etc.
