Once you have completed Idaho ECCW training, you will receive a form signed by the firearms instructor and the legal instructor. You take this to the Sheriff’s department in the county where you live. In some counties, the DMV handles the processing. You will pay the fee. At that time you will be finger printed. They will then run a background check, which can take up to 90 days. You will be notified when the background check is completed, at which time you can return. You are photographed and issued a temporary permit. A permanent permit will be issued within a couple of weeks.
