Most produce in the USA will come with a PLU number on it. It is not required by the government but the PLU system was designed to streamline things for processors and pricing, not consumers.
Here are a few basic guidelines for selecting fruit and vegetables using PLU codes.
Conventionally grown produce will bear a 4-digit number in the 3,000-4,000 range
Organic produce will bear a 5-digit number starting with 9 
Supposedly GMO produce bears a 5-digit number starting with 8, but you don’t see it because they really don’t use those PLU codes to identify GMO grown foods. Why don’t they use the 8-digit code? Growers are afraid consumers won’t buy if it bears a code starting with an 8, so they choose to leave the code off the product. Use of the PLU code is optional, not required.
So the best thing to do is not totally depend upon PLU codes but know who grows your food and know where it comes from.
