Electronic and digital notary seals are the two layers that together make a paperless notarization valid: the electronic seal is the visible image of your notary credentials placed on the document, and the digital certificate is the encryption technology that locks the document the moment you sign so any later change becomes visible. Both pieces are required in most states, and the most common mistake new electronic notaries make is treating them as interchangeable when they do very different jobs.
The Two Components and Why Both Are Required
An electronic seal is the visual equivalent of a traditional rubber stamp. It displays your name, jurisdiction of appointment, commission number, and commission expiration date, and its job is to give anyone looking at the file the familiar visual confirmation that a notary acted on the record. On its own, though, the image secures nothing. Someone could copy and paste that image onto a different file, and the image itself would not flag the forgery.
The digital certificate is what prevents that. Often called a digital signature certificate, it uses Public Key Infrastructure to bind your identity to the document’s contents. The certificate contains a private key known only to you and a corresponding public key that anyone can use to verify the signature. When you sign, the private key generates a unique mathematical fingerprint of the document. If even a single character changes afterward, that fingerprint no longer matches and the verification fails.
So the electronic seal tells a reader who notarized the document, and the digital certificate proves nobody changed it afterward. Both are required for a valid electronic notarization in most states.
How the Tamper-Evident Layer Works
The Revised Uniform Law on Notarial Acts requires notaries to select tamper-evident technology before performing electronic notarial acts but does not mandate a single technical standard. In practice, nearly every state and remote online notarization platform relies on X.509-compliant digital certificates issued by a trusted Certificate Authority.
An X.509 certificate acts as a digital identity card. It verifies your identity through a chain of trust: the Certificate Authority confirms your credentials, issues the certificate, and vouches for the public key embedded in it. When you apply your digital signature, the software uses the private key to create an encrypted hash of the entire document. That hash is a fixed-length string of characters derived from every bit of data in the file. The hash and your public key information are then embedded in the document.
When someone later opens the file, the software recalculates the hash from the current contents and compares it to the original encrypted hash. If they match, the document is intact. If they differ, the software displays a warning that the document has been modified since signing. This check happens automatically in most PDF readers and RON platforms.
What You Need Before You Can Seal Anything
Before you can perform electronic notarial acts, you need to assemble several credentials in the right order. Skipping a step or getting the sequence wrong creates delays that can stall your entire setup.
- An active traditional notary commission in your state. Every state that allows electronic notarization treats the standard commission as a prerequisite.
- Separate electronic notary registration with your state, which most states require through a distinct application. Government filing fees typically range from $10 to $71 depending on the state, and you will generally need to notify your secretary of state about which tamper-evident technology you plan to use.
- An X.509 digital certificate purchased from a Certificate Authority. The certificate must be issued in your name, use PKI technology, include the full certificate chain back to the issuing authority, and not be expired at the time of use. Some states maintain lists of approved providers; others accept any certificate meeting X.509 standards.
- An electronic seal image containing all elements your state requires, which typically means your full name, commission number, jurisdiction, and commission expiration date. Most certificate or platform providers generate this image as part of setup.
- A compatible RON platform if you plan to perform remote notarizations. Not every certificate works with every platform, so confirm compatibility before purchasing.
Identity verification happens at multiple points. The Certificate Authority will verify your identity before issuing your digital certificate, often using knowledge-based authentication or credential analysis tied to your government-issued ID. Your state may impose additional checks during the electronic notary application.
Applying the Seal During a Notarization
The actual sealing sequence during a remote session follows a specific order, and each step serves a distinct security purpose.
You upload or receive the document on a secure RON platform. Once the signer appears on the live audio-video connection and their identity has been verified through the platform’s authentication tools, you place the visual electronic seal on the document. Positioning matters: the seal should not cover any text, signatures, or other content on the page, just as a physical stamp should not obscure anything on paper.
After positioning the visual seal, you apply your digital certificate to sign the document. This is the critical step. The software uses the private key from your X.509 certificate to encrypt a hash of the document’s contents, then verifies the certificate against the Certificate Authority’s records to confirm it is valid and has not been revoked. Once this process completes, the document is locked.
The platform simultaneously generates an audit trail recording the date and time of the notarial act, the identity verification results for all participants, IP addresses, and the type of credential analysis performed. That audit trail is embedded in or associated with the document and becomes part of the permanent record of the transaction.
Keeping Your Seal Under Your Control
Your electronic seal and digital certificate must remain under your exclusive control at all times. No one else, including family members, coworkers, or your employer, may use your notary tools for any purpose. This is a legal requirement in every state that authorizes electronic notarization, not a suggestion.
The consequences of losing control compound quickly. If someone else uses your seal to commit fraud, the investigation starts with you. At minimum, you face the burden of proving you did not perform the fraudulent notarizations, which typically means hiring an attorney at your own expense. State penalties for failing to secure your seal or for fraudulent notarial acts range from commission suspension or revocation to criminal charges. Depending on the state and the severity of the conduct, criminal penalties can include felony charges carrying significant fines and prison time.
Practical steps to protect your credentials include using strong, unique passwords for your digital certificate and RON platform accounts, enabling multi-factor authentication wherever available, never sharing your private key or login credentials, and immediately notifying your secretary of state and Certificate Authority if you believe your certificate has been compromised. If your commission is revoked, most states require you to notify your technology provider immediately and, to the extent possible, destroy or disable the software used for electronic notarizations.
Will Federal Agencies Accept an Electronically Sealed Document
Not always, and not automatically. Federal agencies have their own rules about electronic signatures that do not always align with state electronic notarization laws. The IRS, for example, permits electronic or digital signatures on a wide range of tax forms but through its own approved methods, not through state-authorized RON platforms. For electronically filed returns like Forms 1040, 941, and 1120, the IRS accepts PINs as the signature method. For forms that cannot be e-filed, including estate and gift tax returns and many specialized corporate filings, the IRS permits electronic or digital signatures in lieu of handwritten ones under a separate deviation program.1Internal Revenue Service.

A document properly notarized electronically under state law is generally valid, but if you are submitting to a specific federal agency, check whether that agency has its own electronic signature requirements. Some accept electronically notarized documents without issue. Others require their own signature methods or have not updated their rules to account for remote online notarization. When the receiving party is a federal agency, verify acceptance before the notarization session rather than after.
