Phone Verification
Phone verification is the process of confirming a lead's phone number is active, correctly formatted, owned by the named contact, and dialable to a real human — typically through automated services like Twilio Lookup, Trestle, or specialized number-validation APIs.
Why This Matters
Phone verification operates at multiple levels. Format validation checks NANP structure (10 digits, valid area code). Line-type lookup identifies mobile vs. landline vs. VoIP. Active-line verification confirms the number is currently assigned and not disconnected. Owner verification matches the number to the named contact via reverse lookup. For MCA, mobile vs. landline matters — TCPA compliance varies by line type, and answer rates differ dramatically between owner cells and office landlines. Top vendors run all four levels on every record before delivery.
Frequently Asked Questions
Frequently Asked Questions
What phone verification services do MCA shops use?
Twilio Lookup, Trestle (formerly Ekata), TrueCaller for reverse lookups, Nomorobo for spam/scam detection, RealPhoneValidation for connectivity checks. Many CRM platforms include built-in phone validation; specialized services offer deeper line-type and ownership data.
Why does line-type identification matter?
TCPA imposes stricter requirements on mobile dialing (consent for autodialing, time-of-day rules). Identifying mobile vs. landline lets your dialer apply correct rules per record. Plus, mobile lines convert higher than landlines for owner-direct outbound.
