How Michigan Private Investigator license verification works

A Private Investigator in Michigan is licensed by the MI Private Security / Guard Licensing. PrimaryCheck looks the license up live at the board's public verification system (board lookup) by license number, or by name when no number is supplied. The record the board publishes is captured as evidence, hashed, and rendered into a proof PDF.

Fields returned for this board: status expires issued title disciplinary_actions.

Board note: Corporations, Securities & Commercial Licensing Bureau — its own Accela site (MICLEAR), plain HTTPS. Professional Investigator (3701… numbers; persons and firms both print in the Business Name column, so only a licence-number claim can be verified; name-only → insufficient_identifiers; a firm licence → ambiguous_match). Michigan licenses no individual security guard: 'Security Guard' records are historic agency licences and current agencies are 'Security Guard Agency' → security_guard not covered. 2026-11-04.

What a Private Investigator license check returns

Field check	Passes when
`license_number`	Equal to the board's number, ignoring prefix and leading zeros
`name`	Last name or declared alias matches; first name exact or nickname
`license_type`	The record is a Private Investigator license, strictly (no near-miss types)
`status`	The board shows an active status; probation is active with a flag
`expires`	Expiration is on or after today, where the board publishes it
`disciplinary_actions`	Recorded and flagged with any order documents; never silently dropped

Verdicts: verified, discrepancy, not_found, unable_to_verify (with a reason), pending. See how verdicts are decided.
