Yes, the numbers on the little stickers that are on fruits and vegetables tell more than the number for the cashier to punch in.
The stickers actually tell you a lot about the food you are buying.
A label with four digits indicates conventionally grown food. Labels with five digits that start with an "8" indicate that the food was genetically modified. Labels with five digits that start with a "9" indicate that the food was organically grown.
So... the winning number is hopefully not an "8".
