The IVR System
To use the IVR System, U.S. Law Enforcement Agencies, Public Safety Providers and 911 Service Providers must first register via the IVR Registration Form and receive a Personal Identification Number (PIN). Follow the IVR Process Flow Instructions (provided below) to retrieve data on up to 20 telephone numbers per call.
Use of the IVR System, including requesting or receiving a PIN, is strictly limited to:
- Law Enforcement Agencies: agencies in the United States or of a State or political subdivision thereof that are empowered by law to conduct investigations of or to make arrests for violations of federal, state or local laws; and
- Public Safety Answering Point Providers: entities in the U.S. that perform Public Safety Answering Point (PSAP) functions in the performance of their official duties.
PINs can be shared within an organization. If your organization has already been assigned a PIN, please use that PIN. If your organization has not been assigned a PIN, please submit only one registration form to request a PIN for your organization’s use. If each individual in your organization requires a unique PIN assignment, please submit a separate registration form for each individual.
