Why Finding Phone Numbers Still Matters

Cold calling isn’t dead. Far from it. 50% of sales pipeline still comes from cold calls and reps who combine phone with email outreach see 128% higher response rates compared to using email alone. 

The challenge? Your CRM rarely has accurate phone numbers because contact data decays fast, unlike a digital booklet that can be updated easily. Estimates show 30-70% of B2B data goes bad annually. People change jobs, switch roles, or update numbers, and stale records are left untouched. Even when numbers are logged, they’re often outdated or incorrect. That leaves your reps spending up to 40% of their week chasing missing details instead of selling – a drain worth thousands in lost productivity per rep, every year.

Manual searching doesn’t scale.

• LinkedIn digging → most profiles don’t share direct dials
• Free lookup tools → patchy coverage and outdated data
• Purchased lists → expensive and rarely match your ICP
• Company switchboards → gatekeepers, wasted dials, dead ends

The result? BDRs spend hours chasing numbers instead of talking to prospects.

Surfe delivers verified phone numbers in one click, powered by waterfall enrichment technology across 15+ premium data providers. Invalid entries are filtered out, emails are validated and fresh contact details sync directly to your CRM.
