Cheez It Expiration Code

Locate the product code on the top flap of the cereal box. Read the first three letters or two numbers to determine the product's expiration month. For example, a product that expires in February will start with 'FEB' or '02.' Interpret the two numbers following the first three letters or first two numbers as the product’s expiration day.

How do you interpret the expiration code on your Kellogg’s brand product? The key is to understand that the expiration date is presented in “MMDDY” format — the first two digits represent the month, the next two digits are the day of the month, and the final digit is the year.

Popular Kellogg’s products that we carry (both in our vending machines and sold by the case) include Cheez-Its, Famous Amos cookies, Nutrigrain cereal bars, Pop Tarts, and a variety of cereals (Apple Jacks, Cocoa Krispies, Corn Pops, Froot Loops, Frosted Flakes, Frosted Mini Wheats, Raisin Bran, Rice Krispies, and Special K).
