California draws the identification line at currency of the document rather than at whether the notary believes the person is who they say they are. Acceptable identification must be current, or issued within the past five years, which means a driver's license eight years expired fails on its face regardless of how well the photograph matches. The rule exists because the value of an identification document lies in the issuing authority's recent verification of the holder — a document long expired attests to what an agency confirmed years ago and may have since revoked or superseded. The notary's own judgment about resemblance cannot substitute, since that judgment is exactly what the documentary standard replaces. Nor can two inadequate documents combine into one adequate one. When a signer has no qualifying identification, California provides a defined alternative: one credible witness personally known to the notary and identified by acceptable identification, or two credible witnesses identified by acceptable identification.
