Notary vs. Apostille — What’s the Difference?

Confused about whether your document needs a notary, an apostille, or both? This simple guide explains the difference — and how SignNest Identity Solutions makes the process stress-free in Arizona.

That Moment of Confusion

If you’ve ever stood at the counter with an important document and heard, “You might need both a notary and an apostille,” you’re not alone. It’s one of the most common questions I hear — and for good reason. The words sound official and complicated, but the difference between them is actually simple once it’s explained clearly.

At SignNest Identity Solutions, I help clients every day who just want to make sure their paperwork is accepted the first time — whether it’s staying here in Arizona or traveling abroad. Let’s make sense of these two terms together.

What a Notary Does

A notary public is a licensed official who verifies your identity and signature on a document.When a notary stamps your paper, it means:

• They confirmed you are who you say you are.

• You signed willingly and knowingly.

• The signature happened in the notary’s presence.

In other words — a notary doesn’t prove that your document is true; they prove you are real and that your signature is valid.

Example: You’re signing a Power of Attorney so your relative can handle something on your behalf — a notary confirms your identity and witnesses that signature.

What an Apostille Does

An apostille, on the other hand, authenticates the notary’s authority or the official seal on the document — making it legally valid outside of the United States.

It’s issued by the Arizona Secretary of State, and it’s recognized by any country that’s part of the Hague Apostille Convention.

Think of it like this:

🖋 The notary verifies you.🪶 The apostille verifies the notary or office that signed.

Example: You notarize a Power of Attorney in Arizona, but it needs to be used in Mexico.You’ll first notarize it, then have the Arizona Secretary of State issue an apostille to confirm your notary’s credentials.

When You Might Need Both

Many documents require both steps — notarization first, then an apostille.This is especially true if the paperwork will be used in another country.

For example:

• A Power of Attorney to manage property or finances in Mexico or Spain

• A business agreement signed in Arizona for an international client

• School transcripts being submitted to a foreign university

When you’re unsure, it’s always better to check before mailing or submitting — apostilles can’t be added to documents that weren’t notarized correctly the first time.

How SignNest Simplifies It

At SignNest, I guide clients through both steps — notarization and apostille — from start to finish.That means:

• You don’t have to drive downtown or navigate government forms alone.

• I ensure your documents are notarized properly and submitted to the Secretary of State correctly.

• You’ll have updates at every stage, and documents can be hand-delivered, shipped, or handled via remote online notarization if eligible.

Because your paperwork deserves to be handled with care — and peace of mind.
