Data The accuracy and reliability of our database is unequaled in the directory assistance industry. ComTrust consistently provides customers with accurate data, usually topping accuracy rates of 97 percent. When your employees call directory assistance, they won’t need area codes to get the number they need, and we can also provide the ability to request reverse, statewide or by-address searches. And to ensure that our data is accurate, the Paisley Group, recognized as the industry authority in quality audits, regularly performs third-party analysis of our accuracy and customer fulfillment.
