What is the compliance status of Cognism and LeadIQ?

Cognism is a GDPR compliant B2B data provider that keeps an eye on global regulations. Customers praise Cognism as a company that goes above and beyond on GDPR and CCPA compliance.

“Everything Cognism did [compliance wise] impressed us, from sending out emails to contacts, letting them know you have their data, plus giving them the choice to opt-in or opt-out. It was clear that Cognism took its compliance commitments very seriously. We didn’t see that same level of commitment from other companies.”

- Alexander Porter, Senior Business Development & Inside Sales Lead, Devo

One key differentiator between Cognism and other providers is that Cognism scrubs all mobile numbers against: 

  • TPS/CTPS lists in the UK.
  • Do-Not-Call lists in the USA, Canada and European countries including Germany, France, Spain, Ireland, Belgium, Croatia, Portugal and Sweden.

If a number is marked as TPS or DNC, it means that the user has opted out from receiving unsolicited phone calls by applying to the national do-not-call registry. 

Cognism hides contacts that are on DNC lists, meaning that its customers have complete confidence in the legality of their outreach.
