The United States Census Bureau created a classification system for business entities called the North American Industry Classification System (NAICS). Several company databases and industry research databases use these to organize their information, and it is useful to know these codes when you are looking for industry reports. These codes start at 2 numbers to identify broad industry group and move to 6 to identify specific industries.
721 - Accomodation
721120 - Casino Hotels
713 - Amusement, Gambling, and Recreation Industries
713210 - Casinos (except Casino Hotels)
IBISWorld allows you to search for reports using keywords, company names, or by using NAICS codes. Example Reports: Casino Hotels in the US, Lotteries & Native American Casinos in the US, and Non-Hotel Casinos in the US
