Anyone residing in the towns of Ayer, Devens, Dunstable, Groton, Harvard, Littleton, or Shirley may receive food from the pantry two times every month. We are not income dependent. You must bring only a Proof of Residency (POR) when you visit the Pantry. Once a year you must provide a POR for each member of your household. A POR is an official piece of mail such as a utility bill, rental payment receipt, etc. which lists your name, street address and a recent date. For minors, a POR is either a school or medical paper.
