Answer: 
Proof of residency is required to buy any resident license. A resident is anyone who has been domiciled in this state with a bona fide intent to make this their place of permanent abode, for a period of not less than 6 months immediately preceding the date of application for any license, tag or permit. A senior resident is anyone over 65 who has lived in the state at least 5 years immediately preceding the date of application for a senior license or tag A driver must prove residency with a valid Idaho driver’s license.
