In most states, the ccdw permit number is the same as your Drivers license number; it is that way in Tennessee as well and it will advise the officer when the license check is done that the particular person has a CCDW also. Regardless, if you carry make sure you are legal. I know in Kentucky you can carry a handgun in your glove box and it is not considered concealed. In any job where you have contact with the public and have high dollar items with you, it is a good idea to carry if you can legally. There are a lot of scumbags that are just looking for a crime of opportunity/victim.
