Best Data Enrichment Tools for US Mobile Numbers: Suggestions Needed

·

What’s the best data enrichment tool for mobile numbers in the US? I’m having massive issues with Apollo. Have over 12.62% bad/wrong numbers. Any suggestions?

Have you compared it to ZoomInfo?

We’d always recommend using multiple data sources with a waterfall enrichment setup—way more reliable than relying on a single provider.

Teest and use waterfalls via Clay

Clay waterfall is fantastic. Regardless of your data provider, we typically recommend using a lead verification vendor as the 2nd step before dialing/contacting. Trestle offers a free Data Assessment on any given file and will identify bad contacts / disconnected phone lines: https://trestleiq.com/real-contact-data-assessment/ Trestle Phone Validation is also available in the Clay waterfall if you are using Clay

Brandon B. +1 on the Clay waterfalls, it’s what we use, and then get them verified like Kaiden mentioned here
