It is printed by clean and tidy hot stamping, laser laser, needle punching or steel seal, so it is basically true. Generally, many brands of large companies print the production date in these ways to prevent counterfeiting.

If the production date is printed by inkjet, first check whether these numbers are printed vaguely, ghosting or ink. If it's a non-steel seal or a needle-punched production date, you can wipe it by hand. If it's a real print, it won't be wiped, and if it's printed later, it may be blurred.
