Plain English
What is an apostille?
An apostille is an official certificate that proves a U.S. public document is genuine so that a foreign government will accept it. It was created by the Hague Apostille Convention of 1961 to replace a slow, multi-step legalization process with a single, standardized certificate recognized by every member country.
Notarization
A notary public verifies a signature or certifies a true copy. It happens first and is local — it does not make a document usable abroad on its own.
Apostille
A state's competent authority (or the U.S. Dept. of State for federal documents) authenticates the notary or official. One certificate, accepted by all Hague member countries.
Legalization
For countries NOT in the Convention: a longer chain ending at the destination country's embassy/consulate. Slower and country-specific.
When do you need an apostille?
You typically need one when a U.S. document has to be presented to a foreign government — for example getting married abroad, applying for dual citizenship, enrolling in a foreign university, adopting internationally, or doing business overseas.
State-issued documents (birth certificates, notarized powers of attorney, diplomas) are apostilled by your state’s competent authority. Federal documents (such as an FBI background check) are apostilled by the U.S. Department of State.
If the destination country is not a member of the Hague Convention, you need legalization instead of an apostille.
What it looks like
Every apostille contains the same 10 standardized fields. Here is an illustrative specimen:
- 1.Country United States of America
- 2.has been signed by [NAME OF SIGNER]
- 3.acting in the capacity of [CAPACITY — e.g. Notary Public]
- 4.bears the seal / stamp of [ISSUING OFFICIAL / SEAL]
- 5.at [CITY / PLACE]
- 6.the [DATE]
- 7.by [State] Secretary of State
- 8.No. 0000000
- 9.Seal / Stamp [OFFICIAL SEAL]
- 10.Signature [SIGNATURE]
Common questions
- What is an apostille in simple terms?
- An apostille is a standardized certificate that a designated authority attaches to a public document so that another country which is a member of the Hague Apostille Convention will accept it as genuine — without any further legalization.
- Is an apostille the same as notarization?
- No. Notarization is done by a notary public and verifies a signature or that a copy is true. An apostille is issued by a state's competent authority (or the U.S. Department of State for federal documents) and authenticates the official or notary behind the document for international use. Many documents are notarized first, then apostilled.
- What is the difference between an apostille and legalization?
- Both make a document usable abroad. An apostille is a single certificate accepted by all Hague Convention member countries. Legalization (also called consularization or authentication) is the older, multi-step process used for countries that are NOT in the Convention — it usually requires the destination country's embassy or consulate to certify the document.
