Mobile number
A mobile number reaches the person wherever they are, which matters because a large share of B2B buyers are no longer at a fixed desk. Connect rates on mobile are typically several times higher than on a company main line.
Mobile data is harder to build than email. It comes from a mix of self-reported profile data, opt-in sources, telco-adjacent data and partner networks, so coverage varies by country and by seniority.
Coverage is strongest in North America and the United Kingdom. In parts of Europe and Asia you will see a larger share of direct dials in any list of the same size.
How we handle it
Around nine in ten contacts delivered by LeadNumbers carry a mobile. The rest carry a confirmed direct dial, and the split is shown on every batch.
