A U.S. Postal Service mail processing facility with Siemens Delivery Bar Code Sorter (DBCS) machines used for automated letter sorting. These machines scan barcodes, read addresses, and direct mail to the correct output trays for delivery. Introduced widely in the late 1980s and 1990s, DBCS systems modernized postal operations by improving speed and reducing manual handling. Facilities like this remain an essential part of national logistics, processing millions of mail pieces daily through computer-controlled sorting and routing systems.
