The E911 Modernization Amendment Act of 2025 aims to enhance the District of Columbia's emergency communications system by updating the 911 and 311 telecommunications fees and clarifying the allowable uses of the Emergency and Non-Emergency Number Telephone Calling Systems Fund. The bill introduces new definitions for terms such as "access line," "family or shared plan," and "Next Generation 911," while also revising the structure of the E911 surcharge. Specifically, it establishes a uniform $1.00 monthly fee per access line for non-prepaid technologies, converts the PBX fee to a per-trunk model, and increases the prepaid wireless surcharge from 2% to 5%.

Additionally, the legislation mandates annual reporting on revenues and expenditures, performance metrics, and progress on Next Generation 911 implementation, along with an independent audit by the Chief Financial Officer. It also requires a triennial review of the surcharge to account for inflation, call volume trends, and modernization costs. These updates are designed to ensure that the Office of Unified Communications can maintain a resilient and technologically advanced emergency response system that meets the evolving needs of District residents.
