The numbers on bic cigarrette lighters?

Question

i have began to notice numbers below the place of manufacturing on the metal tip of bic lighters. first it was 301 then went to 302 from the U.S. only and now i just saw one from spain with the number 201. This is always on new lighters that i buy. any ideas on what gives?

Answer 1

It's probably a manufacturing code that identifies when and where it was made, that way when it blows up in your face they know who to go after.
