Post Locations is an informational website that helps people find shipping and postal resources in the United States. It provides listings for USPS Post Offices and UPS, FedEx, and DHL locations, with details such as addresses, operating hours, phone numbers, and available services. Visitors can also use the site to explore passport office information, check postal holidays, and access package-tracking resources.

The site organizes information across major shipping providers and postal services, making it easier to locate a nearby service point or find relevant delivery details. Post Locations states that it is not affiliated with any government agency and that its information is provided for informational purposes only, not as legal or financial advice. The website is supported by third-party advertisements, which help fund hosting, listing verification, updates, and site maintenance.

It also offers contact and correction options, along with privacy and terms policies. The available content presents Post Locations as a directory and reference resource rather than a carrier or shipping-service provider
