What an Apostille Is and Why It Exists
An apostille is a one-page certificate issued under the Hague Convention of 5 October 1961. It replaced the older “chain legalization” process between member countries. The apostille confirms the origin of a public document by authenticating the signature, the official’s capacity, and the seal or stamp on that document so it can be recognized abroad.
It does not validate the document’s contents. In the United States, apostilles are issued by state Secretaries of State for state and local documents, and by the U.S. Department of State Office of Authentications for federal documents.

The Hague Model Certificate
Every valid apostille adheres to the Hague Model Certificate, ensuring a consistent format across all Convention countries. The title must read:
Apostille (Convention de La Haye du 5 octobre 1961)
This French title is mandatory under the Convention, even if the rest of the certificate is in a language other than French. Below that line are ten numbered fields that appear in the same order worldwide.
Field-by-Field Breakdown
- Country: The issuing country, for example, “United States of America, State of California.”
- This public document has been signed by: The name of the person whose signature is being certified.
- Acting in the capacity of: The signer’s role, such as Notary Public or Registrar.
- Bears the seal/stamp of: The office or institution appearing on the document.
- At: The city where the apostille is issued.
- The: The date the apostille was issued.
- By: The competent authority that issued it, for example, the Secretary of State.

- Signature: The signature of the authorized officer.
Illustrated Layout (Visual Description)
Picture a letter-sized certificate framed by a fine border. At the top center, the title reads “APOSTILLE (Convention de La Haye du 5 octobre 1961).” Below it, two columns list the ten standard fields.
The bottom right shows the official seal and the signature of the issuing officer. Many newer certificates include a QR code or barcode for quick online verification. This design follows the Hague Model Certificate described in the HCCH Apostille Handbook.
Language, Seals, and Signatures
Apostilles may appear in English or another local language, but the French title line must always remain. Paper apostilles include an embossed or ink seal and the signature of the issuing officer.
Some states issue digital or electronic apostilles, known as e-Apostilles, that exist entirely in electronic form and are verified through a secure online registry.

Verification and QR Codes
Many states now provide online verification portals. A QR code may appear on the certificate, linking directly to the registry record. If there is no QR code, you can enter the apostille’s number and issue date on the state’s website to confirm authenticity.
Examples:
- California: California Secretary of State
- New York: New York Department of State
- Texas: Texas Secretary of State
How to Spot Red Flags
Compare the apostille with the Hague model to detect irregularities. Common warning signs include:
- Missing or incorrect French title line
- Fields out of order or missing numbering
- Serial number not found in the official register
- Blurred or inconsistent seals and signatures
- QR code leading to an unrelated website
When in doubt, confirm directly with the Secretary of State or the U.S. Department of State Office of Authentications.
Attaching and Storing the Apostille
The Hague Convention permits the apostille to be affixed directly to the document or on a separate page, known as an allonge. The allonge must be firmly affixed with staples, ribbon, or an eyelet. Do not detach or laminate the apostille.
If it becomes separated, contact the issuing authority for reattachment or reissuance. For e-Apostilles, store the original digital file securely and refrain from printing unless necessary.
