Before a notary will stamp your document, they have to be reasonably certain you are the person you claim to be. How notaries verify identity comes down to three accepted methods: checking a current government-issued photo ID, relying on personal knowledge built from a real relationship with you, or taking the sworn word of a credible witness who knows you and can prove their own identity. Remote online notarization layers automated credential checks and a knowledge-based quiz on top. Rules vary by state, but the standard is the same everywhere — the notary must reach reasonable certainty about who you are, or they cannot proceed.
Showing a Government-Issued Photo ID
Presenting a current government-issued photo ID is the most common path. State laws generally require the ID to carry your photograph, a physical description, and your signature. A state driver’s license, a state-issued non-driver ID card, a U.S. passport, and a Department of Defense military ID all qualify in most jurisdictions.
The ID must usually be current and unexpired, but rules on expired documents vary more than most people expect. Some states reject any expired ID outright. Others accept IDs that expired within a defined window, commonly three to five years. A few states carve out narrower exceptions for specific populations, such as residents of assisted living facilities. If your only photo ID is expired, check your state’s notary handbook before your appointment. The notary is legally required to refuse service if your ID doesn’t meet the statutory standard.
Other government-issued documents qualify in some places but not others. Permanent resident cards, federally recognized tribal identification cards, and inmate ID cards issued by correctional facilities are accepted in certain jurisdictions. Tribal IDs must usually contain at least a photograph or signature, and not every tribal-issued card includes the elements state law requires. If you plan to use one of these, confirm ahead of time that your state treats it as satisfactory evidence of identity.
A foreign passport is its own problem. Many don’t use the Latin alphabet, so a notary may be unable to read the bearer’s name. Some states accept foreign passports for all notarial acts; others limit their use to specific transactions like residential real estate closings. If a foreign passport is your only ID, call the notary before you go.
Being Identified Through Personal Knowledge
Nearly every state lets a notary identify you based on personal knowledge alone, without asking for any ID. The legal standard, though, is demanding. The notary must have enough familiarity with you, built through repeated interactions over time, to eliminate reasonable doubt about who you are. A single prior meeting isn’t enough. The notary should have spoken with you multiple times, seen you dealt with by others under the same name, and have no lingering uncertainty.
Statutory language ranges from establishing identity with “reasonable certainty” to eliminating “every reasonable doubt.” In practice the effect is the same: the notary needs a genuine, established relationship with you, not a vague sense of recognition. If there’s any hesitation, the notary should ask for an ID instead. California is the only state that bans this method outright, requiring every signer to produce either a qualifying ID or a credible witness no matter how well the notary knows them.
When a notary relies on personal knowledge, they note that determination in their journal rather than listing ID details, which creates a record that the verification step wasn’t skipped.
Using a Credible Identifying Witness
When you don’t have acceptable ID and the notary doesn’t know you, a credible identifying witness can bridge the gap. This is someone who personally knows you, is willing to swear to your identity, and can present their own valid government-issued ID.
How many witnesses you need depends on the notary’s relationship with them. In many states, one witness is enough if the notary personally knows that witness. If the notary doesn’t know the witness either, two credible witnesses are typically required. Each must present a qualifying ID and swear to your identity separately.
Each witness takes a formal oath or affirmation, swearing under penalty of perjury that you are the person named in the document, that they personally know you, and that they reasonably believe it would be very difficult or impossible for you to obtain standard identification. A witness cannot have a financial interest in the document being notarized or be named in it as a party. The disqualification catches situations that aren’t obvious at first glance. A father vouching for his child’s identity on a vehicle title transfer would be disqualified if the father is receiving the vehicle; if he has no stake in the transaction, the family relationship by itself doesn’t disqualify him.
Lying under oath here is perjury, a felony in every state. Penalties vary but commonly include significant prison time. Courts treat false identification under oath seriously because notarized documents move property, settle estates, and authorize financial transactions, and a fraudulent notarization can strip someone of their home or inheritance.
Identity Verification in Remote Online Notarization
Remote online notarization, now authorized in 47 states and the District of Columbia, uses technology to verify your identity when you and the notary meet by live audio-video instead of in person.1National Association of Secretaries of State. Remote Electronic Notarization The process typically requires at least two identity-proofing steps before the notary can authorize the signing.
The first is credential analysis. You hold your government-issued ID up to your camera, and automated software scans it for security features like watermarks, microprinting, and holograms, comparing the document against a database of authentic templates to flag counterfeits. Good lighting and a camera angle that avoids glare over the machine-readable zones help the scan succeed on the first try.
The second is knowledge-based authentication. The system generates a quiz, usually five questions, drawn from your credit history and public records. Expect questions about past addresses, vehicle registrations, or loan details. Most states require at least four correct answers out of five, and you typically have about two minutes to finish. These aren’t questions someone could answer from your mail; they’re pulled from databases tracking years of your financial and residential history.
If you fail, you generally get a second attempt with some questions swapped. Fail twice and you’ll face a waiting period, commonly 24 to 48 hours depending on the state and platform, before trying again. After a third failure, the notary cannot perform the remote notarization at all, and you’d need to visit a notary in person or try a different remote provider.
Some states are adding biometric verification as a third layer. Facial recognition compares a live image of your face against the photo on your ID. Industry standards treat biometric checks as a supplement to credential analysis and knowledge-based authentication rather than a replacement. The goal is multifactor authentication combining something you possess (your ID), something you know (quiz answers), and something you are (biometric match).
What Happens If You Use False Identification
For the signer, presenting a fraudulent identification document during notarization is a federal crime. The identity fraud statute carries penalties of up to five years in prison for most offenses and up to fifteen years when the fraud involves a forged driver’s license or birth certificate.2Office of the Law Revision Counsel. 18 U.S. Code 1028 – Fraud and Related Activity in Connection With Identification Documents, Authentication Features, and Information State criminal charges often apply separately. The notarized document itself is voidable once the fraud is discovered, meaning any property transfer, power of attorney, or contract executed under that fraudulent notarization can be unwound by a court.
