6. What does the number on the label mean?
The four-digit or five-digit number on the label is the PLU code (price look-up code). It is used to uniquely identify fruit and vegetables and has an important function for consumers: The first or the first two numbers refer to the type of cultivation. Five-digit codes that start with the number 9 refer to products from organic production, whereas four-digit codes or codes starting with 3 or 4 refer to traditionally grown foods. The code for Golden Delicious apples from integrated production, for example, is 4021. Fruit and vegetables of the same variety that differentiate in size, weight and color can have different PLU codes. PLU codes are used to identify products at the cash desk or during the inventory.
