What's inside this directory
A hand-built, verified contact directory for phone appending, covering the companies and people that matter in this market.
It brings together founders, technical leads, and functional decision-makers across the data services landscape — each with a verified work email and a tested direct line. Because the list is built to order, you scope it to the exact titles, company sizes, and regions you target, instead of renting access to a generic database and hoping for the best.
Every record passes four verification gates — domain check, inbox verification, a human researcher audit, and a privacy scrub — so bounces stay under 1.4%. Your finished phone appending ships as a clean CSV (with optional XLSX, direct dials, and CRM field mapping) within 48 hours, and you can test the quality first with a free 50-contact sample.
The segments you get
Phone Appending is organized across the sub-segments that matter for targeting — pick the ones you need and we build to that slice.

Straight answers, before you buy
What does Phone Appending deliver exactly?+
Your input file returns with direct dials and mobiles matched to named contacts, each labeled by line type and validity status so dialers and reps know what they are calling.
How do you handle do-not-call rules?+
Every number is screened against federal and state DNC registries before release, and flags are preserved in the output so downstream dialing logic stays compliant.
Why do mobile match rates differ from landlines?+
Mobile attribution relies on consented and opt-in sources, so we report honest per-type match expectations up front instead of inflating headline numbers.
Can you reverse-lookup existing numbers?+
Yes, reverse matching attaches names, titles, and employers to phone-first files, useful for inbound lead enrichment.
