The annual Stamp Out Hunger drive by the nation's mail carriers will be held Saturday.
Letter carriers collect nonperishable food donations from the public as they walk their routes, and the items are donated to local food banks.
Last year the collection totaled a record 73.4 million pounds of food, according to the National Association of Letter Carriers and the U.S. Postal Service.
The collections started 18 years ago and have brought in more than 980 million pounds of food in that time.
People who want to donate are asked to leave items such as canned goods and packaged pasta near their mailboxes on Saturday.
