Types of Phone Numbers

Multiple phone number types to match your outreach strategy and compliance requirements.

Direct Dials

Office direct lines that bypass the company switchboard and receptionist entirely. These numbers ring directly on the prospect's desk phone, giving you immediate access without navigating phone trees or leaving voicemails with gatekeepers.

Mobile Numbers

Personal cell phone numbers for key decision-makers. Mobile numbers are especially valuable for reaching executives and remote workers who may not be at a desk phone. Ideal for follow-up calls and time-sensitive outreach when you need a response fast.

Company HQ Numbers

Main company headquarters phone numbers with known extensions for specific departments and individuals. Useful for initial outreach, receptionist-assisted transfers, and as a fallback when direct dials are not available for a specific contact.

Phone Verification Process

Every phone number goes through a rigorous multi-step verification pipeline before reaching you.

01

Real-Time Carrier Lookup

Every phone number is checked against carrier databases in real-time to confirm it is an active, in-service line. We verify the carrier, network status, and whether the number has been recently ported or disconnected.

02

Line Type Detection

We classify each number by line type: landline, mobile, VoIP, or toll-free. This allows you to prioritize mobile numbers for SMS-enabled outreach or filter for direct landlines based on your calling strategy.

03

Do-Not-Call List Checking

Numbers are automatically cross-referenced against national and state-level Do-Not-Call (DNC) registries. Flagged numbers are clearly marked so your team stays compliant with TCPA and other telecommunications regulations.

04

Ownership Verification

We cross-reference phone numbers with the contact's identity to confirm that the number actually belongs to the person you intend to reach, reducing wrong-number calls and improving your connect rate significantly.
