WHAT ARE THE ISO CONTAINER SIZE AND TYPE CODES?

In 1995 there was an ISO agreement concerning container marking codes to depict the length, height and type of container in an easy to read sequence. This sequence is composed of four letters or digits that commonly appear right under the container identification sequence.

  • The first character is related to the length of the container
  • The second character is relative to its height.
  • The remaining two elements of the sequence identify the container type and characteristics

DIFFERENT TYPES AND SIZES OF CONTAINERS

Length Height Type
2 – 20 Feet 2 – 8 Feet 6 Inches G1 – General Purpose Container
4 – 40 Feet 5 – 9 Feet 6 Inches “High Cube” R1 – Refrigerated Container
L – 45 Feet U1 – Open Top Container
M – 48 Feet P1 – Platform Container
T1 – Tank Container

Container Size code designation

The two alphanumeric characters used to designate the size code of the container are chosen as follows:

Container Type code designation (ISO 6346 AMENDMENT 3)

The third characters gives the codes to identify the container type and other characteristics related to its type.

Warning: new container type code using an alpha character in the 4th position of the size-type code indicates a container of reduced strength. (See detailed type code ‘b’). see link to table 3

You can also access the container size and type code information via an API ( for direct system integration) using BIC’s BoxTech – Global Container Database.
