Last reviewed November 1, 2026. General information, not legal or compliance advice.

Why it exists

Organizations that grant privileges or enroll providers need independent confirmation that a license, degree or certification is real and current.

Commonly verified items

• State licenses, through the board's lookup or a direct report.
• DEA registration.
• Board certification, through the certifying board.
• Education and training, through the school or program.
• Sanctions and exclusion lists.

How a clinician can help

Keep your numbers and dates correct, respond quickly to requests to release verifications and make sure your name appears the same way everywhere.

Limits of this guide

Which sources count as primary and which standards apply depends on the accrediting body or plan, so ask the organization requesting the verification.
