Arizona Affidavit Of Service By Certified Mail is a notarized legal document that provides proof of service of a legal document sent through the United States Postal Service (USPS) Certified Mail. The affidavit is signed by the person who sent the document and must include the date the document was sent, the name and address of the recipient, a description of the document sent, and the date the recipient signed for the document. There are two types of Arizona Affidavit Of Service By Certified Mail: the green card version and the electronic version. The green card version requires the sender to fill out a green card form and attach it to the document sent via Certified Mail. The electronic version requires the sender to fill out an affidavit online and provide a digital signature. Both versions are accepted in the state of Arizona.
