Validate Phone Number

Overview

What it does: Checks whether a phone number is callable/real by verifying if it's a working number that can receive calls, distinguishing between active, reachable, and disconnected numbers.

When to use it: When you need to verify contact reachability before running calling campaigns, clean up contact lists by identifying bad numbers, or prioritize outreach to contacts with verified callable numbers. Use before bulk calling operations or when auditing data quality.

Business value: Prevents wasted sales rep time calling invalid numbers, improves campaign efficiency and connect rates, maintains accurate contact databases by flagging unusable phone numbers, and enables better territory planning by identifying truly reachable prospects.
