Not In Service Phone Numbers Identification

The popular service that tests the accuracy of your phone numbers.

Cornerstone Pinging is a proprietary process developed with a third party to validate whether telephone numbers are in service. It’s a quick, inexpensive way to check that your house file contact phone numbers are active or “not in service”.
                       
Key Points about Pinging:
  • It’s a non-intrusive solution. A telephone does not ring at the consumer’s house.
  • The cost is minimal. 100,000 records can be checked for $1,000.
