About Us

Post Office Locations is published and maintained by Sumo Coder, an independent publisher of consumer information resources. This site was built for one purpose: helping people quickly find accurate information about United States Postal Service locations near them. We list post offices, contract postal units, and village post offices across all 50 states and Washington, D.C., organized by state and city, so you can find an address, hours, and services without digging through multiple sites.

Every listing includes the details people actually need before a trip to the post office — retail hours, PO box access windows, pickup and bulk mail acceptance times, and which services a given location offers, such as passport appointments and money orders. When a location doesn't publish full hours, we say so plainly rather than leaving a blank field, so you know to call ahead.

We also publish a small set of general reference pages covering common USPS topics — PO boxes, changing your address, holding mail, money orders, holiday closures, and weekend hours — so you can get a quick answer without leaving the site.
