OpenStreetMap can be used for commercial purposes, with the only restriction being that if you make any modifications or updates to the map, you must update the updated map to the OSM community in an open format and agree to the open license. Other uses of the map such as printing, referencing, adding value services, or commercial applications are allowed without using open format (unless there are modifications to the map content).
