Phone Append - Prospecting.com's software increases phone number accuracy for more effective telemarketing. Records are processed against FOUR of the largest compiled databases in the country, all in one step. No other company can touch the volume and quality of our phone append processing. The second step runs the non-matched records through our Directory Assistance phone append database. This database, updated weekly, consists of every household and business in the US. From this file, we carry up to 7 numbers per record, helping to increase matches on the verification process. The third step runs all non-matched records through our Daily New Connects and Disconnects. Match rates are typically lower from the third pass, however these records are the freshest and most up to date.
