It sounds like you're talking about the mold quality control numbers.
On most LEGO parts that a large enough concealed surface, you find three
numbers -- two vary from part to part for the reasons you describe. These are
usually one or two digits long. The third is usually 4 or 5 digits long and is
the "unique" number people have been talking about.
As others in this thread have mentioned, this "unique" number sometimes changes
too, usually due to an engineering design change.
If the available surface is smaller, the engineers usually sacrifice the part
number in favor of the quality control numbers.
