Prospecting businesses rather than consumers? Good news: some rules are relaxed in B2B. Bad news: others still apply. Here's what you need to know.
Do Not Call: Is B2B exempt?
The clear rule
Do Not Call only concerns individuals. Professional numbers (business lines, switchboards, work mobiles) are not covered.
Watch out for traps
- Executive's mobile — If it's their personal number on the list, calling is prohibited
- Small businesses/freelancers — Often reachable on personal mobile = Do Not Call applies
GDPR: Legitimate interest in B2B
In B2C, you generally need consent before prospecting. In B2B, you can invoke legitimate interest.
Legitimate interest conditions
- Link to activity — Your offer must be relevant
- Professional data — Using business contacts, not personal
- Prior information — Person must be able to opt out easily
Summary table B2B vs B2C
| Rule | B2C | Pure B2B |
|---|---|---|
| Do Not Call | Mandatory | Not applicable |
| GDPR Consent | Required | Legitimate interest OK |
| Hours 10am-8pm | Mandatory | Recommended |
FAQ
Can I call an executive on their mobile?
