# Personal Identity Verification
Personal Identity Verification (PIV) is the U.S. federal framework for interoperable identity credentials used by federal employees and contractors.
## Notebook evidence
PIV appears with CAC and ECA on PDF page 12 of [[Scanned_20260730-1845]]. The grouping shows the notebook moving from consumer account identity toward credentials whose trust depends on formal issuance, certificate chains, and institutional policy.
## Boundary
The page does not prove that any PIV credential was applied for, issued, possessed, or used. It records comparative identity-infrastructure research.
