United States Post Office

The service windows at this north Napa branch are open an hour later than at the downtown Napa post office. Even when they're closed, the lobby is open for boxholders to collect mail and customers to use the Automated Postal Center (APC).  This machine weighs and dispenses postage for most packages and envelopes so that Napans can send out mail 24 hours a  day, seven days a week.
