As long as you meet the minimum age requirements and are not criminally prohibited, no license is required for a shotgun.
Local ordinances and state law determines whether or not you need a "permit" to own a shotgun. The laws and ordinances differ by locality. The Federal government doesn't require you to have a permit to own a firearm. You can find out by calling your local Sheriff's office and asking them. Mary Kay at personalsecurityzone.com

No to both.
You only need a license if you wish to wear a handgun openly or concealed (it is illegal to do either without a permit). But no permit is needed to buy or own any otherwise-legal gun (rifle, shotgun, pistol) or to carry a rifle or shotgun.
Shotguns require a background check. As for permits, it depends on your state - most do not require a permit, although some may require an identification card for firearms owners.
