"Residency" within a certain US jurisdiction, such as a voting precinct, can be proven if the driver's license or state ID has the home address printed on it corresponding to that jurisdiction. Utility bills or other pieces of official printed mail can also suffice for this purpose. In the case of voting, citizenship must also be proven with a passport, birth certificate, or signed citizenship affidavit. Receiving in-state tuition at a state's public college or university also requires proof of residency using one of the above methods. Ownership of property, proved by a deed, also immediately confers residency in most cases.
