Given a name and address, IDENTIFY will confirm or append a correct telephone number. DL/411 (electronic directory assistance, EDA), an optional feature of IDENTIFY, enables you to tap into the databases of the Regional Bell Operating Companies (RBOCs) in a cost-efficient manner. And, at your option, IDENTIFY will append to each matched input record known or inferred demographic characteristics (such as homeownership) that help you better define individual consumers and the composition of their households.
