Licensing authority
Who actually issues an EMS licence in Indiana?
Indiana Department of Homeland Security, EMS Division (Indiana EMS Commission)
Partly supported
Indiana is one of the states that runs EMS out of homeland security rather than health — the pages live under in.gov/dhs. The EMS Commission owns the rules (IAC Title 836) while the EMS Division administers certification; the page names the Division but not the parent department in prose.

the EMS Division is required to collect Social Security numbers from all current license holders and new applicants
