Michigan’s blue USPS collection boxes are common in Detroit’s metro, Grand Rapids, Ann Arbor, and smaller towns—often near business districts, campuses, and retail corridors. For tight timelines, compare a few nearby boxes on the city map and pick a location that fits your route. Schedules can differ between downtown routes and residential streets; verify the label on the box for today’s last pickup. When in doubt, boxes near post offices and major retail clusters may collect later.
In larger metros such as Detroit, Grand Rapids, Lansing, you’ll often find multiple boxes within a few blocks.
Tip: if timing is tight, check two or three nearby boxes—some collect later than others. For specific directions, tap a mailbox to view its address, map, and today’s pickup time.
