Where B2B mobile numbers exist: a phone number finder hit-rate map by role and country, from 225 profile, email and name lookups

Description and use

The study found that only 13.3 % of profiles contain mobile numbers; hit rates vary by role and country, informing call‑list planning and cost.

Problem

Determine which B2B professionals actually have mobile phone numbers to inform call‑list construction and cost planning.

Outcome

Only 30 of 225 profiles (13.3%) had mobile numbers; hit rates differ by role and country, with US sales leaders at 32% and UK sales leaders at 0%. The key used (URL, email, name+domain) does not change the result, but email type (work vs personal) slightly affects success. Lead‑list actors can pre‑filter for phone presence, saving cost.

Workflow

• Run a single profile‑URL lookup on 225 profiles
• Record number found, no number on record, and profile removed/not found counts
• Repeat the lookup for the same 25 US sales leaders using email and name+domain keys
• Run a lead‑list actor with phoneRequired to generate a list that already contains numbers
• Use the B2B Leads Finder flag to filter rows with phoneOnRecord before lookup
• Analyze hit‑rate map to decide which call lists are viable

Evidence

225 entries, 35 seconds, 30 numbers found.

In the US, one in three sales leaders, one in four marketing leaders and recruiters, one in five founders, one in twelve engineers.

The same 25 US sales leaders, three ways: by profile URL, by the email address on their row, and by name with the company domain.

The cheaper version of the same list is the flag. Run B2B Leads Finder with the same filters, read phoneOnRecord, and only the rows where it is true go to the phone lookup.
