Container shipping is a global transportation method. It is often used in international trade transactions so there needs to be uniformity in symbols. Container symbols are characters - parameters with the function of distinguishing into different types of containers. Basically, the container symbol will include the following basic issues:

The container identification system includes 4 main components:

– Owner code: Owner code (also known as container prefix) includes 3 capital letters that are unified and registered with the international registry through the national registry. Join or register directly with the Bureau International des Containers - BIC (Bureau International des Containers et du Transport Intermodal).

 

A number of other companies own and operate containers with different titles

– Device type symbol: is one of the three capital letters below, corresponding to a type of device:

U: freight container (freight container)

J: detachable freight container-related equipment

Z: tractor (trailer) or trailer (chassis)

– Serial number: this is the container number, consisting of 6 digits. If the serial number is not 6 digits long, zeroes will be added to make it 6 digits long. For example, if the serial number is 1234, then add 2 zeros, and the full serial number will be 001234. This serial number is set by the container owner, but ensures the principle of each Number used only for one container.

– Check digit: is a digit (behind the serial number), used to check the accuracy of the preceding character string, including: prefix, serial number. For each character string including prefix and serial number, applying the container check digit calculation method, the necessary check digit will be calculated.

– Size code: 2 characters (letters or numbers). The first character represents the length of the container, the number 4 in the example above represents the length of this container is 40ft (12,192m). The second character represents the width and height of the container, the numeral 2 represents the height of 8ft 6in (2.591m).

– Style code: 2 characters. The first character indicates the type of container, in the example above: G represents a general cargo container. The second character represents the main characteristic related to the container, the number 1 (after the letter G) means the container has a ventilation door on top.

– Mandatory signs: container load, electrical hazard warning; tall containers.

– Optional signs: maximum net mass, country code

In addition to the three main types of symbols, on the container shell there are also signs describing other necessary information.
