Certification Verification System

This search functionality is currently undergoing maintenance! We are working to have it back up shortly.

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

Online verification can confirm 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:
