This guide was reviewed and updated in November 2025 and is valid for 2026.

What qualifies as a valid school record (Illinois)
For diplomas and transcripts, ILSOS will authenticate Illinois-notarized registrar certifications (or notarized true copies executed by the registrar).
The school official (registrar/principal) signs, and an Illinois notary notarizes that signature; then ILSOS issues the apostille/certification. University registrar guidance confirms the sequence: verify, notarize, submit to ILSOS.
Registrar notarization — how to do it right
- The registrar (or designated school official) signs a certification referencing the student name, document type (diploma/transcript), date, and page count.
- An Illinois Notary Public completes a full acknowledgment/jurat: venue, date, notary signature (printed name), commission no./expiry, and seal (if applicable).
- For transcripts, use an official transcript with registrar certification; for diplomas, many schools issue a notarized duplicate/true copy via the registrar.
"I, [Registrar Name], Registrar of [Institution], certify the attached [Diploma/Transcript] for [Student Full Name] is a true and correct school record issued by [Institution]. Signed on [Date] in [City], Illinois." (Registrar signature — notarized by an Illinois Notary Public)
Step-by-step process (diploma/transcript)
- 1
Coordinate with the registrar
Request a notarized registrar certification attached to your diploma/transcript (or a notarized duplicate for diplomas). Universities document this workflow and can assist.
- 2
Complete the ILSOS application
Download and fill the Application for Authentication or Apostille. Include your destination country, contact info, and return method.
- 3
Payment
Attach a $2 check or money order per document, payable to "Secretary of State." (You may submit one check for multiple documents; see form.)
- 4
Submit your packet
Include the notarized school record(s), the completed application, payment, and a return envelope/label.
Mail (Springfield): Index Department, 111 E. Monroe, Springfield, IL 62756
Walk-in: Chicago — 69 W. Washington St., Suite 1240; Springfield — 2701 S. Dirksen Pkwy. (confirm current hours on ILSOS before visiting)
- 5
Processing & return
Walk-in requests are frequently same-day; mail-in typically ~7–10 business days plus mailing time.
When you do NOT need an apostille
- •If the record is used only within the U.S.
- •If a foreign authority explicitly accepts a notarized/certified copy without apostille (rare — get it in writing).
- •If the destination is non-Hague, you may need state certification → (sometimes) U.S. Department of State → consular legalization instead; confirm with the consulate.
Common rejection reasons
- Missing or incomplete notarization on the registrar's signature (no venue/date/commission).
- Submitting a plain photocopy that was not issued/attested by the registrar.
- Wrong address (mail vs. walk-in) or missing return label/envelope.
- Incorrect fee or payee (must be "Secretary of State").
