Price Look-Up codes or Product Lookup Number, commonly called PLU codes or PLU numbers, are identification numbers affixed to produce in grocery stores and supermarkets to make check-out and inventory control easier, faster, and more accurate. The code is a four-digit number, currently in the 3000-4000 range, identifying the type of bulk produce (and related items such as nuts and herbs), usually including the variety. Organic produce is denoted by a five-digit number whose first digit is 9; an 8 prefix indicates genetically modified food. The codes have been in use since 1990. Currently, there are over 1300 universal PLU codes assigned.

Price look-up codes are generally printed on small stickers or tags, and are considered inconvenient by some. Various new technologies are under consideration, including etching using lasers and printing or "tattooing" using ink made from substances such as blueberry juice.^[1]
