Certification Verification System
Use the search below to find and verify an individual's certification. For formal requests, see more information below.
This free service can verify a nurse's current 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.
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.
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:
