Which of the following is NOT an acceptable method to confirm a signer's identity during a traditional notarization?

The method identified as not acceptable for confirming a signer's identity during a traditional notarization is professional references. This method relies on the opinions or affirmations of other individuals regarding the signer's identity, which does not fulfill the specific requirements set forth by notary laws for verifying identity.

When conducting a traditional notarization, notaries are typically required to rely on direct methods of identification, such as personal knowledge of the signer or satisfactory evidence. Personal knowledge implies that the notary has already met and identified the signer in a previous interaction, ensuring a reliable basis for identity verification. Satisfactory evidence includes the presentation of government-issued identification that contains a photo and signature, or similar documentation that can clearly prove the identity of the individual.

Witness testimony can serve as a method of verification in some jurisdictions, but it must be used in accordance with established guidelines. In contrast, professional references do not provide the direct verification needed to comply with legal requirements for notarizations, making it an unacceptable method for confirming identity in this context.
