Common Questions
Direct dial accuracy typically ranges 60-85% for top tools. Mobile numbers are harder - expect 50-70% accuracy. ZoomInfo and Cognism lead on accuracy. Always expect some wrong numbers and plan your calling accordingly.
Direct dial is an office phone that rings directly on someone desk, bypassing the main switchboard. Mobile is a personal cell phone. Mobile numbers are more valuable but harder to find accurately and raise more privacy concerns.
In the US, B2B cold calling is generally legal under TCPA, though you must honor Do Not Call requests. In Europe, GDPR requires legitimate interest. Some tools like Cognism specialize in compliant data. Check your local regulations before calling.
