The Complete Guide to Adding a Notary Stamp to a PDF
Electronic notarization has gone from a niche option to a mainstream requirement in the span of a few years. As of 2025, the majority of US states have enacted laws permitting Remote Online Notarization (RON) or at minimum electronic notarization on documents presented in person. That means millions of notaries now need to know how to properly apply a digital stamp to a PDF.
This guide covers what an electronic notary stamp needs to contain, where it should be placed on the document, the legal landscape by state, and the practical steps to get it right.
What Is an Electronic Notary Stamp?
An electronic notary stamp (or electronic notary seal) is the digital equivalent of the physical rubber stamp a notary uses to emboss paper documents. It typically appears as a circular or rectangular image containing the notary's name, commission number, state, and expiration date — all required by most states.
Unlike a physical stamp, the electronic version is an image file (usually PNG with transparent background) embedded directly into the PDF at the location of the notarial act.
What Must a Notary Stamp Include?
Requirements vary by state, but the following elements are nearly universal:
Notary's full name as it appears on the commission. State of commission. Commission number (where applicable — not all states use these). Commission expiration date. The words "Notary Public" or equivalent. Some states also require the county of commission.
A few states — Virginia and Florida, for example — have published specific design templates for electronic seals that must be followed. Others allow notaries to design their own seal as long as it contains the required information.

| New York | Yes | Yes | RON enacted 2023; county requirement applies |
| California | Limited | Yes | IPEN allowed; RON has restrictions |
| Pennsylvania | Yes | Yes | Commission number required on seal |

Where to Place the Notary Stamp on a PDF
The notary stamp should appear on the same page as the notarial certificate — the section of the document that contains the notary's acknowledgment or jurat language. This is almost always the last page of the document, or a separate certificate page appended to the end.
Specifically, place the stamp adjacent to where the notary signature will appear — typically below the notarial certificate text and to the left or right of the signature line. It should not overlap any of the document's substantive text.
Step-by-Step: Adding Your Notary Stamp to a PDF
Create or obtain your electronic seal image
Most electronic notary seal vendors provide you with a PNG file when you order. Ensure it has a transparent background and meets your state's size requirements (typically 1" minimum diameter when printed).
Navigate to the notarial certificate page
Identify the page containing the acknowledgment or jurat text. This is where your stamp belongs.
Place the stamp in the certificate area
Position the stamp near the notary signature line — either to the left of the signature block or in a designated seal area if the form has one. Avoid overlapping text.
Add your electronic signature
The stamp alone is not sufficient. Add your electronic signature adjacent to the stamp, along with the date of notarization. Many states require your commission expiration date to also appear.
Apply a digital signature certificate (if required)
Some states require the PDF to also contain a cryptographic digital signature — a different thing from a visual signature image. Check your state's RON requirements. This is typically handled by dedicated RON platform software.

Upload your document, position your seal, and download the stamped PDF. No Acrobat required.

Can I use any PDF tool to add my notary stamp?
Technically yes — any tool that can embed an image in a PDF will work for the visual stamp. The key is ensuring the stamp is embedded as a permanent part of the document (not a floating annotation that can be moved), and that the PDF is not locked in a way that prevents the stamp from being added.
Does the notary stamp need to be tamper-evident?
For RON, most states require the final document to be tamper-evident — meaning any changes made after signing should be detectable. This is typically handled by the RON platform applying a document-level digital signature certificate after all parties have signed. The visual stamp image alone does not provide tamper-evidence.
What's the difference between an acknowledgment and a jurat?
An acknowledgment is used when a notary verifies the signer's identity and confirms they signed voluntarily — the signer doesn't need to be present when the document was signed, only when notarized. A jurat requires the signer to sign in the notary's presence and swear or affirm the document's contents are true. Both require a notary stamp and signature.
