The short answer
The short version.
- Mobile coverage is highest in owner operated and field based segments and lowest in large regulated enterprises.
- United States and Canada carry the deepest B2B mobile coverage. The United Kingdom is strong for SMB and thinner at enterprise.
- Any provider claiming uniform high mobile coverage across every country and company size is describing a sales target, not a dataset.
- Plan for a mix, and require that every record carries at least one number that reaches a person.
Coverage questions get vague answers because the honest answer depends on three variables at once: country, company size and how the role works.
These are the ranges we see in practice, and what to do when a segment comes in thin.
Coverage by country
US and Canadian B2B mobile coverage is the deepest, the UK is strong in SMB, Australia sits close behind, and coverage thins in most of continental Europe for privacy reasons.
Coverage reflects how data is contributed and what local rules permit, not how hard a provider tries.
| Country | SMB under 50 staff | Mid market | Enterprise |
|---|---|---|---|
| United States | 70 to 85% | 55 to 70% | 35 to 50% |
| Canada | 65 to 80% | 50 to 65% | 30 to 45% |
| United Kingdom | 60 to 75% | 45 to 60% | 25 to 40% |
| Australia | 60 to 75% | 45 to 60% | 25 to 40% |
Coverage by how the role works
Desk bound roles have direct dials and often no discoverable mobile. Roles that move have mobiles and frequently no desk line at all.
This is why a plumbing contractor list can be 80 percent mobile while a bank compliance list is 30 percent, with no difference in provider effort.
- Highest mobile coverage: owners, trades principals, field service and construction leadership, real estate, clinic owners.
- Mixed: sales, marketing and operations leadership in hybrid companies.
- Lowest: finance, legal, compliance and procurement inside large enterprises.
What to do when a segment is thin
Three options, in order of how little they compromise. Widen geography inside the same profile first. Then add an adjacent secondary role that sits close to the buyer. Only then accept work email only records for part of the volume.
What you should not do is accept switchboard numbers to hit a count. That inflates the row count and destroys the connect rate, which is the whole point of buying phone data.
Key takeaways
- Coverage depends on country, company size and whether the role sits at a desk.
- US and Canadian SMB segments carry the deepest mobile coverage.
- Widen geography or add an adjacent role before loosening on number type.
- Never accept switchboards to fill a quota.

Frequently asked questions
What percentage of B2B contacts have a mobile number available?
Roughly 70 to 85 percent in US small business segments, falling to 35 to 50 percent at enterprise level, with similar patterns in Canada, the UK and Australia.
Why does my list have fewer mobiles than expected?
Usually because the target roles are desk bound or the companies are large. Both reduce mobile availability regardless of provider.
