They make sure your mail is delivered each day, but letter carriers are adding something else to their route next month.
"We get cards and we distribute them to all of the customers," said Dominick Frattaroli, local food drive coordinator and letter carrier.
Cards inviting people to take part in the Stamp Out Hunger food drive, led by the National Association of Letter Carriers.
"Just to help out, every little bit counts. One can, ten cans, five cans. Anything non-perishable would help," said Frattaroli.
He says items can then be bagged for pick up.
"The mailman will come and you leave it by the mailbox and he will pick it up and put it in his truck, bring it back," said Frattaroli.
The food is then distributed to local food banks, like the Food Bank of Lower Fairfield County in Stamford. Executive Director Kate Lombardo says this time of year, donations are essential.
"It gets us through the summer months when children need food the most. They're home, they're not at school getting the subsidized breakfast and lunch program," said Lombardo, executive director of the Food Bank of Lower Fairfield County.
She says in the summer, they lose about 40,000 pounds of food per month. Making Stamford and New Canaan's 76,000 pound delivery a big help.
"It's just a consolidated effort by everybody and you can just see the joy that everybody has on their faces while they're doing it," said Jeffrey Salamon, Stamford postmaster.
Nationally, the drive has supplied local pantries with more than 1 billion pounds of food in the past 20 years. It's the largest one day food drive in the nation, and they say they don't mind the extra weight in their mail trucks.
"Sometimes it gets a little tough, gets a little hectic but I feel like hopefully I'm helping people," said Frattaroli.
The national food drive takes place on May 10, 2014.
