Best Practices for Enriching Contacts with Direct Work Phone Numbers in Custom Waterfalls

·Jul 17, 2026 12:35 PM·

Question -- I'm interested in enriching a contact to get a person's direct dial work phone number (not mobile) and then I'd fall back to the company phone number. Some of the enrichment options for phone are unclear. Any advice of good enrichment steps for direct work phone I can build into a custom waterfall?

So far, not good results with RocketReach, Wiza, or Zeliq. Wondering if I just need to go with main company phone. 😞

Andrew T. Contact out, Apollo has given the best results for phone numbers. If it doesn't return one, I usually fall back to the company's main phone number.
