Proof
The remote online notarization (RON) platform formerly known as Notarize, used for IRS Form 1583 and other notarial acts.
Proof (formerly Notarize) is the leading U.S. remote online notarization (RON) platform. A signer joins a video session with a commissioned notary public — typically Virginia or Florida-commissioned for cross-state acceptance — and the notary performs identity verification, witnesses the signature, applies their digital seal, and produces a notarized PDF. Proof is widely used for USPS Form 1583, real-estate documents, and other instruments requiring notarization. RON acceptance varies by state; check destination-state recognition rules before relying on it.
