Container Number Explanation:

AYN 105424324

A container number consists of a prefix, a 6-digit serial number, and a check digit.

The first three letters of the prefix are known as the owner code, which is unique to each company and is registered with the Bureau International des Containers (BIC).

The last letter of the prefix can have the following values:

U - for containers

J - for detachable container equipment

Z - for trailers and container chassis

The serial number identifies the container among those owned by the same company.

The check digit is calculated based on the prefix and the serial number. It helps prevent errors when entering the container number into IT systems at ports or cargo terminals.
