Document Authentication for Iran
By John F. Heinz, Managing Director, Prismark Signature Services
Published: August 7, 2026
Quick Answer
Iran is not a party to the Hague Apostille Convention, so documents intended for use in Iran may require a multi-step authentication and legalization process rather than the simpler apostille process used for Hague Convention countries.
For a California-issued or properly notarized California document, the process generally begins with the California Secretary of State. California issues a single certificate titled “Apostille” for documents being used outside the United States, regardless of the destination country. Because Iran is a non-Hague destination, however, that California certificate may be only the first authentication stage. Additional federal authentication and destination-country legalization may be required.
Key Takeaways
- Iran is not a Hague Apostille Convention country.
- California issues a certificate titled “Apostille” for foreign-use documents regardless of destination, including non-Hague countries.
- For California state or locally issued documents, the California Secretary of State stage may be followed by authentication through the U.S. Department of State.
- Federal documents generally begin with the appropriate federal authentication process rather than the California Secretary of State.
- Additional destination-country or consular legalization may be required after the U.S. authentication stages.
- The exact requirements depend on the document and its intended use in Iran.

Why Is Iran Different from a Hague Country?
For a Hague Convention country, the appropriate apostille generally completes the international authentication requirement under the Convention. Iran is different because it is not a party to the Hague Apostille Convention.
California’s terminology can be confusing: the California Secretary of State uses a single certificate titled “Apostille” for documents going outside the United States. For a document destined for Iran, that certificate authenticates the California public official or notarial signature, but it should not be assumed to complete the entire Iran authentication process.
Common Documents Authenticated for Use in Iran
Documents prepared for use in Iran may include birth certificates, marriage certificates, death certificates, divorce decrees, court documents, powers of attorney, affidavits, diplomas, transcripts, school records, corporate documents, and criminal background checks.
These documents may be requested for family matters, inheritance, property matters, education, business transactions, or other official purposes. The receiving authority determines which documents are required.
Do I Need a Certified Copy?
For many government-issued records, yes. California birth, marriage, and death records should generally be official certified copies suitable for authentication. Court records generally require official certified court copies.
Privately signed, educational, corporate, and other documents may require different preparation. Prismark can review the document before processing begins to help identify the appropriate preparation path.
California Document or Federal Document?
The authentication path depends on who issued the document. California state and locally issued documents generally begin with the California Secretary of State once properly prepared. For use in a non-Hague country such as Iran, the state-authenticated document may then require an Authentication Certificate from the U.S. Department of State.
Documents issued by U.S. federal agencies generally follow the federal authentication process rather than the California Secretary of State process. For example, an FBI background check is a federal document.
Are Additional Steps Required?
They may be. Because Iran is not part of the Hague Apostille Convention, completing the California and/or federal authentication stage may not complete the process. Additional destination-country or consular legalization may be required before the document can be used in Iran.
The exact requirements can vary by document and intended use. Prismark can help identify and coordinate the appropriate authentication path without requiring clients to navigate the multiple agencies and stages on their own.
Do My Documents Need to Be Translated?
Translation requirements depend on the authority receiving the document in Iran and the document’s intended use. Clients should confirm the destination requirements before arranging translation.
If Persian translation is required, Prismark can coordinate professional translation services through our trusted translation partners.
Authentication Does Not Guarantee Acceptance
Authentication verifies the signature, official capacity, and, when applicable, the seal or stamp associated with a public document. It does not validate the contents of the document or determine whether it satisfies a particular requirement in Iran.
The receiving authority may still impose separate requirements concerning the document’s form, recency, translation, or intended use.
