Certification Verification System
Welcome to ONCC's Online Credential Verification System.
This free service is provided by ONCC to assist individuals and organizations requiring verification of a nurse's individual ONCC Certification status. Names of nurses currently certified by ONCC are available to the public. The only information that will be provided via this service is the name of the certified nurse, home city/state, and certification status. Confidential information that will not be released includes names of candidates registered to take a certification examination, names of nurses who fail the examination, and individual test scores of candidates.
ONCC can provide 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 a specific individual.
Third party requests for credential verifications that require completion of a verification form or 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:
