The Arizona Apostle Specimen Signature Card is an official document used to verify an individual’s identity and signature for authentication purposes. It is used to authenticate the signature of an individual in order to prove that a document is valid and can be accepted in an international context. The Arizona Apostle Specimen Signature Card is issued by the Secretary of State’s office and is required for documents that are being used outside the United States. There are two types of Arizona Apostle Specimen Signature Cards: the Notarized Signature Card and the Self-Authenticated Signature Card. The Notarized Signature Card requires two witnesses who must witness the individual signing the signature card and must be accompanied by a notary public. The Self-Authenticated Signature Card requires the individual to sign the signature card in the presence of an authorized government official. Both signature cards must include a photograph, signature, and identifying information of the individual.
