How often does the USPS reach every address in the nation?

The United States Postal Service (USPS) has a long-standing commitment to delivering mail to every address in the country six days a week. This service generally occurs Monday through Saturday, ensuring that the vast majority of residents and businesses receive their mail consistently and reliably. This frequency of delivery is integral to the USPS mission of providing universal service, making it a crucial part of maintaining connectivity within communities, facilitating commerce, and ensuring access to important communications.

In contrast, some alternatives propose fewer delivery days, which do not align with the USPS's operational standards for nationwide service. By delivering six days a week, the USPS effectively meets customer expectations and leverages its extensive infrastructure to reach all addresses, promoting prompt and efficient mail service.
