what post office delivers my mail

The post office that delivers your mail is typically the one closest to your physical street address. In smaller towns and cities, there may only be a single post office for the community, and that would be your post office. You can use the USPS Service Locator tool on their website to find your local post office. To use the tool, enter your address and select "post offices" under the location type dropdown menu. The tool will then search for post offices in your area, and you can better zero in on the post office that handles your mail. You can also check your tracking information on any recent package to see which post office handled it last. If you need to contact USPS directly to find out which office delivers your mail, you can call their general phone number at 1-800-ASK-USPS or send an email to USPS.
