Universal Service Obligation (USO)

**Universal Service**

Universal service is a principle, primarily applied in regulated industries, that aims to ensure a baseline level of essential services is available to all residents of a country, regardless of income, location, or other demographic factors. The goal is to make these services accessible at just, reasonable, and affordable rates. This concept has been widely adopted in various sectors, including telecommunications, postal services, and utilities, with the intention of promoting social and economic inclusion.

The concept originated in the 19th century with postal reforms that established uniform, affordable rates. In the telecommunications sector, universal service originally focused on interconnecting telephone networks to create a unified system. Over time, its meaning evolved to encompass the broader goal of providing access to telephone service for all citizens. This is often achieved through government policies and regulations that may require service providers to offer services in underserved areas or to low-income households, sometimes supported by subsidies or universal service funds.
