Idaho Apostille Guide — How to Authenticate Documents

Who issues Idaho apostilles?

The Idaho Secretary of State (Notary Division / Notary Clerks and Deputy Secretaries of State) issues apostilles for Hague Convention countries and authentication certificates for non-Hague destinations. The office can authenticate only documents issued by Idaho officials or notarized by an Idaho Notary Public. Vital records, court documents, school transcripts/diplomas (school-notarized), and certain notarized papers are common. Always confirm the receiving country accepts apostilles and that your document is an Idaho-origin certified copy or Idaho-notarized original—out-of-state notarizations must go to that other state’s Secretary of State.

Typical steps

1) Obtain a properly certified copy from the correct Idaho issuer (vital records office, clerk of court, school registrar, etc.), or an original document notarized by an Idaho Notary Public. School transcripts must be signed by a school official and notarized—only the school can provide that notarization. 2) Complete the Apostille/Authentication Request Form (PDF on the SOS site) and name the destination country so the office can issue the correct format. 3) Submit the form, document(s), and fee by mail or by in-person appointment in Boise. 4) Receive the apostille (or authentication) attached to your document; mail returns are typically first-class unless you enclose a prepaid overnight airbill.

Walk-in vs mail vs courier

In-person service in Boise is by appointment only (Monday–Friday, roughly 8:00 a.m.–noon and 2:00–4:00 p.m.; no appointments over the noon–2:00 p.m. window). Schedule online or call the Notary & Apostille line. Depending on volume, you may need to leave documents and return later. Mail-in DIY is usually cheapest if you have buffer for transit plus daily processing—Mailing Address: Secretary of State’s Office, Attn: Notary Department, PO Box 83720, Boise ID 83720-0080; overnight street address: 450 N 4th Street, Boise ID 83702. Couriers help with multi-document batches, travelers who cannot wait on mail, or when you need someone to hand-carry an appointment in Boise and return originals with tracking.

Fee and timeline estimates

Treat figures as estimates and verify on the official Idaho Secretary of State apostille page before you ship originals. The statutory fee has been published at $10.00 per document for an apostille or authentication (checks/money orders payable to “Secretary of State” or “Idaho Secretary of State”; credit cards accepted, often with a small nonrefundable processor fee). In-person appointments are processed by appointment schedule; mail requests are processed daily as received and returned by first-class mail unless you enclose a pre-addressed, prepaid airbill for overnight return. Budget separately for certified-copy fees from the issuing agency, the SOS fee, courier service if used, and tracked shipping both ways. Fees and hours can change—confirm on sos.idaho.gov/apostille/.

When an expedited courier helps

Idaho does not publish a separate rush fee that shortens the official processing clock; speed comes from appointment timing, prepaid overnight return, or a courier who can coordinate Boise drop-off/pickup. Couriers are most useful for embassy or consular deadlines, overseas employment or school start dates, adoption timelines, multi-document packages, and out-of-area clients who cannot travel to Boise. Compare turnaround quotes, insurance for originals, and whether they can also help obtain Idaho certified copies before filing.
