The Emergency Services Communication Bureau (ESCB) is the division of the Maine Public Utilities Commission that manages the statewide 911 system, which is the component of the emergency response system that delivers 911 calls and displays the telephone number and physical location of the caller at one of Maine’s 24 Public Safety Answering Points (PSAPs). The ESCB is funded by the E911 surcharge which is assessed on all wireline, wireless (prepaid and postpaid) and VoIP service.
