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.
7211 - Traveler Accommodation
721110 - Hotels (except Casino Hotels) and Motels
721191 - Bed-and-Breakfast Inns
IBISWorld allows you to search for reports using keywords, company names, or by using NAICS codes. Example Reports: Ski & Snowboard Resorts in the US, Bed & Breakfast & Hostel Accommodations in the US, and Boutique Hotels in the US
