Need a document issued in Oklahoma apostilled for use overseas? You don’t have to be in Oklahoma — or visit us in California — to get it done. Orange County Apostille handles Oklahoma documents by mail for clients in Oklahoma City, Tulsa, and Norman, and everywhere else in the state. Send your documents in and we manage the entire authentication process.
How it works for Oklahoma: A Oklahoma document is apostilled by the Oklahoma Secretary of State. We prepare and submit your document to that office for you, so you never have to navigate the process yourself.

- Mail your Oklahoma documents to us (or upload them where allowed).

Federal documents from Oklahoma
Some documents issued to Oklahoma residents are federal — such as FBI background checks, IRS Form 6166, and documents signed by a U.S. federal official. These are not apostilled by the Oklahoma Secretary of State; they’re authenticated by the U.S. Department of State in Washington, D.C. We handle those too. See our federal apostille page.
Going to a non-Hague country?
If your Oklahoma document is destined for a country that isn’t part of the Hague Apostille Convention, it needs full embassy or consulate legalization rather than an apostille. We manage that multi-step process from start to finish.
