Cartridge razors? Date codes? 20 questions? If the question is do cartridge razors have date codes, I would say no, they're just plastic disposable bits of life. Certainly not built to last. No reason for date codes.
For some time the cartridges were marked with a date code to aid in product rotation. I haven't seen one in several years to know if they still are, If that is what we're talking about.
