A HUBZone small business concern may have offices or facilities in multiple HUBZones or even outside a HUBZone. However, in order to be certified as a HUBZone small business concern, the concern's principal office must be located in a HUBZone (except see§ 126.200(c)(2) for concerns owned by Indian Tribal Governments).
