Why?
Because it doesn't make any sense to a systems analyst that company X
should design its computer systems on the basis of a coding scheme that
is designed by company Y and might be changed by Company Y at any time

Many US companies discovered this to their cost a few years ago when
they had been using the Social Security number as the unique identifier
in their personnel systems, and the US Government changed its format.
