Certification Verification System

Use the search below to find and verify an individual's active or Emeritus certification. For formal requests, see more information below.

This free service can verify a nurse's current and Emeritus ONCC certification status. Names of nurses currently certified by ONCC are available to the public. This service provides the name of the certified nurse, home city/state, and certification status. It does not provide confidential information, including names of candidates registered to take a certification examination, names of nurses who fail the examination, and individual candidate's test scores. Emeritus status provides special recognition to permanently-retired nurses who once held an ONCC active certification.

This system provides primary source verification for OCN®, AOCN®, AOCNP®, AOCNS®, CPON®, CPHON®, CBCN® and BMTCN® certification status. ONCC cannot provide primary source verification for the educational preparation or professional experience of an individual.

If you suspect a nurse is misrepresenting him/herself as an ONCC-certified nurse (active or Emeritus), please report it to ONCC. Reports of misconduct are confidential and you may report anonymously by leaving a message at 412-859-6224 or emailing oncc.tipline@oncc.org.

Third party requests for credential verification that require ONCC to complete a verification form or provide verification on official letterhead must request the verification in writing, include a $15 fee, and include the nurse's full name and home address. Please send requests for written verification to:
