Communication with a member of a class is established based on the location of a mobile device initiating the communication and the physical address of the member. A class can include members that share common attributes, characteristics, and/or traits. Example classes can include business types (e.g., restaurants), brand names (BEST BUY®, COMPUSA®), services, etc. To establish the communication, the mobile device provides a message to set up a call. Upon receipt of the call setup message, a particular member of the class is selected from members of the class based on the location of the mobile device sending the call setup message and the physical addresses of members of the class. Upon determination of the particular member, communication is established between the mobile device and the particular member.
