Data Quality by Region

United States

ZoomInfo wins

Larger database, deeper company hierarchies, stronger technographic data. ZoomInfo is the market leader for US B2B data.

Europe (EMEA)

Cognism wins

Built for European markets. Better coverage, GDPR-native, human-verified mobile numbers for UK, DACH, Nordics, and Southern Europe.

Asia-Pacific

Both weak

Neither platform has strong APAC coverage. Consider regional specialists or Apollo (which has community-contributed APAC data).

Cognism Diamond Data: The Phone Number Advantage

Cognism's Diamond Data is their strongest differentiator. Unlike ZoomInfo's algorithmically matched phone numbers, Cognism employs human researchers to verify mobile numbers through phone calls. This produces significantly higher connect rates for sales teams that rely on cold calling.

ZoomInfo Phone Data

  • Algorithmically matched direct dials
  • 15-25% connect rate (reported)
  • Mix of direct and switchboard numbers
  • Larger total volume of numbers

Cognism Diamond Data

  • Human-verified mobile numbers
  • 40-60% connect rate (reported)
  • Verified personal mobiles, not switchboards
  • Smaller volume but much higher quality

Verdict

Cognism

Teams selling into Europe

Native EMEA data, GDPR compliance, and Diamond Data make Cognism the clear choice for European-focused sales teams.

Cognism

Phone-first outbound teams

If cold calling is a major part of your sales motion, Diamond Data's human-verified mobiles dramatically improve connect rates.

ZoomInfo

US-focused enterprise teams

ZoomInfo's US database is unmatched. Deeper org charts, stronger technographic data, and the largest B2B contact database in North America.
