Saturday marks the 22nd anniversary of one of America’s great day of giving – the National Association of Letter Carriers Stamp Out Hunger Food Drive.

Each year on the second Saturday in May, letter carriers across the country collect non-perishable food donations. Donations go directly to local food pantries to provide food to people in the Paris area who need help.

Last year, more than 74 million pounds of food was collected nationally, feeding an estimated 30 million people. Over the course of its 21-year history, the drive has collected well over one billion pounds of food, thanks to a postal service universal delivery network that spans the entire nation, including Puerto Rico, Guam, and U.S. Virgin Islands.

The need for food donations is great. Currently, 49 million Americans – one in six – are unsure where their next meal is coming from. Sixteen million are children who feel hunger’s impact on their overall health and ability to perform in school. And nearly 5 million seniors over age 60 are food insecure, with many who live on fixed incomes often too embarrassed to ask for help.

The Letter Carriers food drive seeks to replenish food banks and pantries, which often receive the majority of their donations during the Thanksgiving and Christmas holiday season.

Participating in this year’s Letter Carrier Stamp Out Hunger Food Drive is simple. Just leave a non-perishable food donation in a bag by your mailbox on Saturday and your letter carrier will do the rest.
