While most companies operating their own container ships own about a bazillion of their own containers, there are also quite a few companies which specialize in leasing containers to them to tide them over shortages or for other reasons. In such cases it is necessary to include on the containers information regarding the ownership of the containers.

There really are countless millions of containers wandering about the world like vagabonds and it is a testimony to human ingenuity that anyone was able to devise a system for keeping up with the things.
