Telephone Number Appending
Telephone Number Appending can be carried out for both Business and Residential addresses.
For residential, once ex-directory is removed, the file contains approximately 54% of the population. The file comprises 25 million residential and 2.4 million business telephone numbers and is updated weekly.
DES can compare your database with telephone numbers and either verify an existing telephone number that you hold, or add a telephone number to an address where it is incorrect or missing.
This service is generally used in conjunction with TPS suppression.
