About USPS

The United States Postal Service is an independent agency of the executive branch of the United States federal government, responsible for providing postal service in the United States. Founded in 1775, with Benjamin Franklin as the first postmaster general, USPS has grown into one of the most significant postal services worldwide, known for its reliability, efficiency, and wide-reaching network.

What USPS Offers

USPS offers a broad spectrum of services, including but not limited to, domestic and international mail delivery, package shipping, priority and express mail, and various financial services. Its commitment to serving every American household and business has made it an indispensable part of daily life in the United States.

Special Services and Programs

USPS is not just about sending letters and packages. It offers a range of specialized services designed to cater to diverse needs. For instance, the Certified Mail service provides the sender with a mailing receipt and electronic verification that an article was delivered or that a delivery attempt was made. Meanwhile, services like Priority Mail Express come with a money-back guarantee, offering overnight delivery to most U.S. addresses, including PO Boxes.

Another notable program is the Every Door Direct Mail (EDDM) service, which allows businesses to target a marketing campaign to specific neighborhoods without needing to know names or street addresses. This service is particularly beneficial for small businesses looking to increase their local presence.

International Services

USPS also plays a significant role in international mail and package delivery. With services like Global Express Guaranteed and Priority Mail International, USPS provides reliable and cost-effective options for sending items overseas. These services come with varying delivery timeframes, tracking options, and insurance coverage, ensuring that international shipping needs are met with precision and care.

Digital and Technological Innovations

In the digital age, USPS has embraced technology to enhance customer experience and operational efficiency. The USPS Mobile app, for instance, allows users to track packages, schedule pickups, buy stamps, and locate post offices from their smartphones. Additionally, the Informed Delivery service lets customers digitally preview their incoming mail and manage their packages scheduled to arrive soon.

Seasonal Operations

During peak seasons, such as the winter holidays, USPS adjusts its operations to handle the increased volume of mail and packages. Extended hours, additional workforce, and even Sunday deliveries become part of the strategy to ensure timely delivery during these high-demand periods. Understanding these seasonal adjustments can help customers plan their shipping and mailing activities more effectively.

Mail Security and Privacy

USPS takes the security and privacy of mail very seriously. With measures in place to protect against mail theft and fraud, customers can trust USPS with sensitive and valuable shipments. The Postal Inspection Service works tirelessly to enforce the laws that defend the nation’s mail system from illegal or dangerous use.
