Your completed voter registration form must contain the number of your Arizona driver's license, or non-operating identification license issued pursuant to A.R.S. Sec. 28-3165, if the license is current and valid. If you do not have a current and valid Arizona driver's license or non-operating identification license, you must include the last four digits of your Social Security number if one has been issued to you. If you do not have a current and valid driver's license or non-operating identification license or a Social Security number, please write "NONE" on the form. A unique identifying number will be assigned by the Secretary of State.

be a resident of Arizona and the county listed on your registration

By Mail: Citizen Instructions

If this is your first time registering to vote in Arizona, your voter registration form also must include proof of citizenship or you may be registered as a federal-only voter. To be eligible to vote a “full ballot,” you must submit proof of citizenship with your registration form. A “full ballot” includes all federal, state, county, and local races and ballot questions for which you are eligible to vote. If you have an Arizona driver's license or non-operating identification issued after October 1, 1996, write the number on the form. This will serve as proof of citizenship and no additional documents are needed. If not, you should attach proof of citizenship to the form. Please include a copy of one of the following documents: birth certificate and supporting legal documentation (i.e. marriage certificate) if the name on the birth certificate is not the same as your current legal name; passport; naturalization documents or ID number; Bureau of Indian Affairs (BIA) card number, tribal treaty card number, or tribal enrollment number; or Tribal Certificate of Indian Blood or Tribal or BIA Affidavit of Birth. Do not send original documents. Photocopies will not be returned to you.
