Frequently Asked Questions

Does the Phone Scrub service label Disconnected or Out-of-Service Phone Numbers?

No, the service uses the rule-based phone number format of active Area codes and Exchange codes (NPA & NXX) by phone carrier to determine if a phone number is valid. Phone numbers labeled “I – Invalid” or “U – Unknown” are often out-of-service numbers but the service is unable to determine if specific phone numbers are disconnected.

Does the Phone Scrub service replace Incorrect Phone Numbers?

No, the service does not identify incorrect numbers (phone numbers which do not belong to the individuals in your records). It also does not add phone numbers to your lists. To add phone numbers to your lists you will use Datazapp’s Phone Append service.

Does the Phone Scrub service guarantee DNC or TCPA compliance?

No, the service does not guarantee legal compliance nor does Datazapp accept liability for telemarketing practices. The service is meant to be a risk-mitigation tool.
