Human Verification: Many top providers employ teams who kenya phone number list call and verify numbers, ensuring accuracy and direct connection.
Community Sourcing: In some models, users contribute data in exchange for access.
Partnerships: Licensing data from other sources.
Compliance: Reputable providers prioritize compliance with regulations like GDPR (which often has a "legitimate interest" basis for B2B professional contact data) and CCPA. They usually provide tools to help users stay compliant (e.g., DNC list scrubbing, opt-out management).
Examples: Cognism (known for high-accuracy, often human-verified mobile numbers, strong in EMEA), ZoomInfo (vast database with many direct dials), UpLead (focus on verified data), Apollo.io, Lusha, Seamless.AI, RocketReach.
