Postal workers in California will be delivering food along with their mail over the weekend, taking the goods to local charities and community food banks.
USPS will be delivering the food packages to charities in Goleta, Santa Barbara, Montecito and Carpinteria on Saturday, December 12th.
Customers are invited to leave donations of canned goods or other unopened, non-perishable food items in bags near their mailboxes on Saturday.
USPS added that any high-nutrition foods such as canned fruit, vegetables, meat and fish are needed by the food banks, as well as peanut butter, cereal, soup, rice and beans.
Jennifer Vo, postmaster for Santa Barbara, said that the drive has "grown into an annual tradition for the letter carriers of Santa Barbara and the surrounding communities".
She added: "There's nothing worse than being hungry during the holidays, so we appreciate our customers giving all that they can
it's our way of giving back to the community, especially in these times of great need."
Ms Vo highlighted the heavy demand on food banks in California, especially over the holiday period, adding that some of them struggle to keep their shelves stocked.
