They also enable manufacturers and retailers to rotate their stock.
USDA advises consumers to use eggs within three to 5 weeks of purchase, and states, “The ‘sell-by’ date will usually expire during that length of time, but the eggs are perfectly safe to use.” UPC Use: Scanning for price, inventory, and marketing Universal Product Codes (UPC codes), or bar codes, appear on most packaged product labels because scanners can “read” them quickly to record the price of the product.
UPC codes are used not only for pricing, but to help manufacturers record inventory levels and track sales for marketing purposes.
