Year-round and around the clock, we stand ready to support all sites across the National Park System. ISB Special Agents also serve on multi-agency task forces and regularly collaborate with investigators of other agencies.
NPS Dispatch and Communications Center staff may access the ISB Duty Agent schedule here. Other NPS personnel may call the Emergency Incident Coordination Center (EICC) at 888-246-4335. Ask the dispatcher to connect you with the ISB Duty Agent.
