We do not have an expiration date on our packages. We put the Manufacturing Date on all of our bags that reads: MFG DATE 00-00-00 X0. Wild Bird Food can last 18 - 24 months beyond the Manufacturing Date as long as it's stored properly (a cool, dry place, preferably in a sealed container once the bag is opened).
