Apostille vs. Authentication (Embassy Legalization): Which One Does Your Document Need?

When a foreign government, university, employer, or bank asks for a U.S. document to be "legalized," it will accept one of two certificates: an apostille or an authentication certificate followed by embassy legalization. You do not get to choose. The destination country decides, based on whether it belongs to the Hague Apostille Convention. Getting this wrong means paying twice and losing weeks, so this guide explains how to tell which one you need, what each costs at the federal level, how long the U.S. Department of State takes, and the order of steps for each path.

The one question that decides it

Is the country where the document will be used a party to the Hague Apostille Convention?

• Yes → your document needs an apostille. A single certificate, issued by the competent U.S. authority, is recognized by every other member country. No embassy involvement.
• No → your document needs an authentication certificate (sometimes called a "certificate of authentication" or "chain authentication"), and then legalization by that country's embassy or consulate in the United States.

Membership changes: China joined in November 2023 and Canada in January 2024, converting what used to be multi-step legalizations into single apostilles. Countries that remain outside the convention as of this writing include the United Arab Emirates, Vietnam, Egypt, Kuwait, Qatar, and Thailand. Always check the current HCCH status table before you start.

Who issues the certificate depends on the document

• State-issued or notarized documents — birth, marriage, and death certificates; diplomas; powers of attorney; corporate documents notarized in a state — are apostilled or authenticated by the Secretary of State of the issuing state.
• Federally issued documents — FBI background checks, USPTO records, FDA certificates, documents signed by federal officials or notarized at a U.S. embassy — go to the U.S. Department of State's Office of Authentications.
• For non-Hague countries, state-level documents usually need both: the state authentication first, then the State Department certificate, then the embassy.

Our explainer What is an apostille? covers the state-level path in more detail; this article focuses on the federal step and the choice between the two certificates.

U.S. Department of State fees and processing times

The Office of Authentications publishes its terms on travel.state.gov:

• Fee: $20 per document, non-refundable, whether you request an apostille or an authentication certificate. Pay by check or money order by mail, or by card or contactless payment in person.
• By mail: processed within 5 weeks of the day the office receives the request; mail to the Office of Authentications, 44132 Mercure Circle, PO Box 1206, Sterling, VA 20166-1206, with a prepaid return envelope.
• Walk-in drop-off at 600 19th Street NW, Washington, D.C., Monday–Thursday 7:30–9:00 a.m., no appointment: processed within 7 business days. A representative may drop off and pick up on your behalf.
• Emergency appointments (travel within two weeks because an immediate family member abroad has died or is gravely ill) are processed the same day with documentary proof.

Every request needs Form DS-4194 listing the country where each document will be used. That country field is not a formality — it tells the office whether to issue an apostille or an authentication certificate, and a wrong entry produces the wrong certificate.

Step-by-step: apostille (Hague country)

1. Obtain a certified copy or have the document notarized as required.
2. Submit to the correct authority — state Secretary of State for state documents, the Office of Authentications for federal documents — with the destination country named.
3. Receive the apostille attached to the document. Done; no embassy step.

Step-by-step: authentication and legalization (non-Hague country)

1. Notarize or obtain a certified copy.
2. State Secretary of State authentication (for state documents).
3. U.S. Department of State authentication certificate ($20 per document, timelines above).
4. Legalization at the destination country's embassy or consulate, which sets its own fees, forms, and turnaround — from a few days to several weeks. Some embassies require translations or a cover letter from the requesting party.

Because each stage waits on the previous one, a non-Hague legalization for a state document routinely takes six to ten weeks by mail. Walk-in service at the State Department and a courier at the embassy can compress that to two or three weeks; that is the core of what our document authentication service does.

Common mistakes

• Requesting an apostille for a non-Hague country. The UAE, for example, will reject it, and the $20 is gone.
• Skipping the state step for a state-issued document. The Office of Authentications will not certify a birth certificate that has not been authenticated by its issuing state.
• Old or short-form vital records. Many countries and some U.S. states require a recently issued long-form certificate. Our vital records service can order a fresh certified copy first.
• Missing translations. Certificates are issued in English; the receiving country may require a certified translation attached before or after legalization.

Frequently asked questions

What is the difference between an apostille and an authentication?

An apostille is a single certificate accepted by all Hague Apostille Convention countries. An authentication certificate is used for non-member countries and must be followed by legalization at that country's embassy or consulate. The destination country determines which one you need.

How much does the U.S. Department of State charge?

$20 per document, non-refundable, for either an apostille or an authentication certificate. State Secretary of State fees and embassy legalization fees are separate.

How long does authentication take?

The State Department processes mailed requests within five weeks of receipt and walk-in drop-offs within seven business days. Add state and embassy steps for non-Hague countries — six to ten weeks by mail is typical for the full chain.

Does China need an apostille or an authentication?

An apostille. China joined the Hague Apostille Convention in November 2023, so documents for use in mainland China no longer require Chinese embassy legalization.

Can someone else drop off my documents at the State Department?

Yes. The Office of Authentications allows a representative or company to drop off and pick up on your behalf; the representative's name is recorded on the receipt and photo ID is required for pick-up.
