A shipping container number is displayed on the container doors and consists of a combination of four letters, six digits, and a final check digit. This number provides essential information used to identify the container’s owner company, container category, serial number, and a single digit that verifies the accuracy of the record.
The use of shipping container numbers is part of a global identification system regulated by the Bureau International des Containers (BIC). Established in 1933, BIC is responsible for assigning container codes to ensure standardized tracking and management of shipping containers worldwide.
The numbering format follows the guidelines of the International Organization for Standardization (ISO), specifically ISO 6346:2022, which governs container identification. This standardized system enables efficient tracking and provides detailed information about each container across international shipping operations.
