About Container Number Validation
- • Container numbers follow ISO 6346 international standard
- • Format: 3 letters (owner prefix) + 1 letter (category) + 6 digits (serial) + 1 digit (check)
- • Category: U = Container, J = Detachable Equipment, Z = Trailer/Chassis
- • The last digit is a check digit calculated from the preceding characters
- • Valid format does not prove the container exists, is available, or owned by the prefix holder
- • This tool only validates the format, not ownership, status, or availability
