This dataset provides the information of all the carriers providing Lifeline and Affordable Connectivity Program (ACP) service, their customer service number, service type, state, and URL. The purpose of this dataset is to provide the most accurate list of carriers providing service in a particular area within a given state, through the use of zip codes. To ensure that this data is up-to-date and accurate, it is refreshed periodically to add new carriers and the corresponding zip codes of their designated service areas, update the zip codes for existing carriers, and remove zip codes for carriers that have relinquished their ETC designation. In the event that a user enters a zip code that does not return any service provider(s), a complete listing of the state in which the zip code is found will be returned with the recommendation that the consumer confirm the availability of Lifeline or ACP service in their chosen zip code with a service provider from that state.
