Apostille vs. Authentication: What's the Difference?
By John F. Heinz, Managing Director, Prismark Signature Services
Published: August 5, 2026
Quick Answer
People often use the terms “apostille” and “authentication” as if they mean the same thing, but they don’t.
An apostille is a specific type of authentication used when a document will be used in a country that accepts apostilles. If the destination country does not accept apostilles, your document will usually need to go through a different authentication process, which may include consular legalization.
Key Takeaways
- An apostille is a form of document authentication.
- Not all authentication results in an apostille.
- The destination country determines which process applies.
- Non-Hague countries often require additional authentication and consular legalization.

What’s the Difference?
Think of authentication as the process and an apostille as one possible result.
When a document will be used in a Hague Convention country, that process usually ends with an apostille.
When the document will be used in a non-Hague Convention country, it usually continues through additional authentication and consular legalization instead.
The most important thing to remember is that the destination country determines which process your document must follow.
When Is Authentication Used?
Authentication may be required whenever a document will be used in another country. For Hague Convention countries, that authentication is typically completed with an apostille. For non-Hague countries, additional authentication and legalization steps may be required.
Every international document request is different. The document, where it was issued, and the destination country all affect the process.
How Prismark Can Help
Prismark Signature Services reviews your documents and destination country before processing begins to help identify the appropriate authentication path.
If your document is intended for a Hague Convention country, we’ll help determine the appropriate apostille process based on the type of document and where it was issued or notarized. If the destination is a non-Hague country, additional state or federal authentication and embassy or consular legalization may be required. Prismark can help coordinate the appropriate process from start to finish.
