Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Go to concrete.org/certification/verifyacertification.aspx, the official ACI Certified Personnel Directory verification tool.
Use Search Option 1 (ID number) if you have the individual's ACI-issued wallet card, and corroborate identity with government-issued photo ID per ACI's stated procedure.
Use Search Option 2 (last name) if you don't have an ID number, but independently corroborate any match against the individual's claimed identity.
Use Search Option 3 if you're a specifier checking regional density of certified individuals rather than verifying one specific person.
For field use, the ACI Certification Verify mobile app offers the same three search options as the web tool.
Known gotchas
Read the directory's Terms of Use page first — ACI restricts the tool to verification purposes, and a name match alone is not proof of identity.
This is a lookup tool, not an API — no documented public endpoint for bulk/automated verification as of July 2026.
