United States Address Management System (US AMS)

The United States Address Management System (US AMS) is a system used by the United States Postal Service (USPS) to manage and maintain the accuracy of address data across the country. The system ensures that addresses are standardized, up-to-date, and consistent, enabling efficient mail sorting and delivery. By continuously verifying and updating address information, the US AMS helps reduce the number of undeliverable or misrouted mail pieces. It is an essential tool for both the USPS and businesses that rely on accurate addressing for shipping and customer communications.
