In many states, people in certain occupations must have licenses or occupational permits. Often, they have to pass state examinations before they can get these permits and conduct business. States usually require licensing for auto mechanics, plumbers, electricians, building contractors, collection agents, insurance agents, real estate brokers, repossessors, and anyone who provides personal services (i.e., barbers, cosmetologists, doctors and nurses). Contact your state government offices to get a complete list of occupations that require licensing.
In most cases, you won't have to worry about this. However, a few types of businesses do require federal licensing, including meat processors, radio and TV stations, and investment advisory services. The Federal Trade Commission can tell you if your business requires a federal license.
