Which document is most commonly used to verify a signer's identity?

A government-issued photo ID is the most reliable and commonly used document to verify a signer's identity in the notarization process. Such identification possesses several key features that make it ideal for establishing identity. First, it includes a photograph, which allows the notary to visually confirm that the person presenting the ID matches the image. Additionally, these IDs are typically issued by a recognized authority, such as the state or federal government, thus providing a level of authenticity and security that other forms of identification might not offer.

While a birth certificate, social security card, and utility bill can provide useful information, they do not serve as effective forms of verification for identity in a notarization setting. A birth certificate does not have a photo and is primarily used for establishing date of birth rather than identity. A social security card also lacks a photo and is not considered a standalone form of identification for verification purposes. A utility bill, although it may indicate a person’s name and address, does not carry the same weight as a government-issued photo ID and cannot fully verify identity on its own. Therefore, the government-issued photo ID is the preferred choice for confirming the identity of a signer in notarial acts.
