To find a local USPS number for a specific post office, use the "Locations" link on the USPS website and enter your location. You can call the national USPS number at 1-800-275-8777.

Find Your Local USPS Number

If you need to find out post office hours, fix issues with local mail delivery or check on a service available at a certain post office, you could get in touch with that location directly. The USPS website has an easy-to-use lookup tool that can help find contact information and other details for the nearest post office location.

You can visit the USPS official website and click the "Locations" link at the top of the page to bring up a form where you can either enter your city and state or your ZIP Code. Alternatively, you can click the "Use Current Location" link to have your web browser detect your location and put your coordinates in the location search field. Once you've set your location, you'll want to select the "Location Types" menu and choose "Post Offices" to filter out results for other types of shipping locations. You can then click "Search" to bring up the nearest post office results.

Select the location for which you're looking in the list to see detailed information such as the local phone and fax numbers, post office hours, address and available on-site and online services. When calling the local USPS number, check the retail hours listed so that you can get in touch with a live person.
