Size and Type Codes
ISO 6346 also gives size and type codes for containers. When displayed on the container, the size and type codes shall be used as a whole.
The codes are compiled of the following elements:
- First character, representing the length (coded)
- Second character, representing the width and height (coded)
- Third and fourth character indicating the type of the container
The following is an overview of the most common codes:

Famous quotes containing the words size, type and/or codes:
“Learn to shrink yourself to the size of the company you are in. Take their tone, whatever it may be, and excell in it if you can; but never pretend to give the tone. A free conversation will no more bear a dictator than a free government will.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“They had supposed their formula was fixed.
They had obeyed instructions to devise
A type of cold, a type of hooded gaze.
But when the Negroes came they were perplexed.
These Negroes looked like men....”
—Gwendolyn Brooks (b. 1917)
“I cannot help thinking that the menace of Hell makes as many devils as the severe penal codes of inhuman humanity make villains.”
—George Gordon Noel Byron (1788–1824)
