How often must an Ohio CCW license be renewed?

Ohio CCW licenses must be renewed every 5 years. This option is correct because Ohio state law requires a renewal of CCW licenses every 5 years to ensure that individuals are up-to-date with any changes in firearm laws and regulations. Options A and B are incorrect because they are both shorter time periods and do not align with Ohio state laws. Option D is also incorrect because all CCW licenses, including those in Ohio, must be renewed at some point.
