Apostille (Diploma/Transcript Authentication)*

NKU graduates who plan to work or further their education abroad may need to authenticate their degree(s) and transcripts.  This process is often referred to as an Apostille, which is the verification and legalization of a document for international use under the terms of the Hague Convention.*

Step 1: Order your documents

  • Diploma: Place a diploma order (CeDiploma recommended).
  • Transcript: Place a transcript order and select Hold for Pick Up.

Step 2: Request notarization from NKU

Email registrar@nku.edu with:

  • Your name and a copy of a valid photo ID
  • Diploma order number (if applicable)
  • Transcript order number (if applicable)
  • Mailling address for notarized documents to be sent to

Our office will notarize your documents. Please allow extra processing time. The notarized documents will be return to you at the provided address.

Step 3: Certify the notary’s signature

Before the Kentucky Secretary of State can issue an Apostille, the Campbell County Clerk must certify the NKU notary’s signature.

  • Take or mail your notarized diploma/transcript to the Campbell County Clerk.
  • Pay any required fees directly to the Clerk.
  • Once certified, the Clerk will return the document to you.

Step 4: Complete the Apostille process with the Kentucky Secretary of State

  1. Download and complete the Apostille/Authentication Request Form from the Kentucky Secretary of State website.
  2. Mail the certified documents, the completed request form, and payment to the Secretary of State following the instructions on their site.

Important Notes

  • NKU cannot obtain county clerk certification or Apostilles on your behalf. This step must be completed by the graduate.
  • Requirements differ by country. Verify with the receiving institution or authority what documentation and authentication are required.
  • More information on authentication of U.S. academic credentials for international use is available at the U.S. Department of State website
  • For countries that do not recognize the Hague Convention, you may need federal authentication from the U.S. Department of State Office of Authentications. In this case, be sure your documents are returned to you before completing the federal submission.
