The Paisley Group’s NDA Performance IndexSM Finds

Over the past twelve months, user paid directory assistance (DA) providers performed at levels that are almost as high as statistically possible, making the United States’ DA service “the best of the best.”
There are three components that drive the accuracy of DA: the automated front-end systems, the operators and the databases. According to the National Directory Assistance Performance IndexSM, an independent analysis published semi-annually by The Paisley Group, Ltd. (PGL), automated systems are performing at 98.7% accuracy, operators at 98.3% accuracy and databases at 95.0% accuracy resulting in 91.0% of all calls being handled accurately. The margin of error is +/- 3.2%. [click heading for more]
