Contact Validation Search

Improve your contact strategy with current phone data

Failure to comply with the CFPB’s Unfair, Deceptive, or Abusive Acts or Practices (UDAAP) and Telephone Consumer Protection Act (TCPA) policies can result in costly fines and reputational damage. To optimize your customer contact strategies, TransUnion’s Contact Validation Search helps you quickly confirm the line type and ownership of a consumer-provided phone number.

Implementing our batch Contact Validation solution can bolster your existing compliance efforts and improve operational efficiency by reducing outbound calls to outdated phone numbers. Plus, you can more effectively assess changes in consumer-provided phone numbers with fresh and reliable updates.

Contact Validation Search provides validation of phone ownership details from telecom network data.

Using inputs, such as phone number, first and last names and right party contact date, you can receive actionable information about changes in ownership since the right party contact date, as well as current phone number, line type and carrier information if ownership has changed.


  • Confirm change in ownership or line type

  • Update consumer contact data with current phone number and carrier inform

  • Receive updated and actionable insights about phone data

  • Available via batch to deliver fresh data from telecom networks
