OHIO has constitutional carry, also called permitless concealed carry, since June 13, 2022.
Under Ohio Revised Code §2923.111:
You must be 21 or older.
You must be legally allowed to possess a firearm.
You do not need a concealed handgun license (CHL) to carry a concealed handgun.
You can carry concealed in places where a licensed CHL holder is legally allowed to carry.
You are still subject to Ohio’s restrictions on prohibited places and other firearm laws.
Ohio still issues concealed-carry licenses, which can be useful for carrying in other states that recognize Ohio’s license.
