Which documents can Oklahoma apostille?
These are state-issued documents. Each guide covers the exact copy type and steps for that document in Oklahoma.

| Diploma / degree certificate | A diploma, typically notarized, apostilled for work or teaching abroad. |
| Marriage certificate | A certified marriage record apostilled by the state that recorded it. |

Federal documents are different
Some documents never go to Oklahoma. FBI background checks, IRS letters (like Form 6166), and naturalization certificates are federal — they go only to the U.S. Department of State — Office of Authentications, at $20 per document. If you hold one of these, start at the federal channel guide instead.
Going to a non-Hague country?
If your destination is not a Hague Apostille Convention member, an apostille is not enough. You need the Oklahoma authority's certification, then US Department of State authentication, then embassy legalization. Use the Country Checker to see your destination's chain, or read apostille vs. authentication.
Common rejection reasons in Oklahoma
- Submitting a photocopy or a hospital souvenir certificate instead of a certified copy.
- Wrong or missing payment — Oklahoma expects check or money order payable to the authority.
- No return envelope, or an untracked one, which stalls the whole order.
