Telephone canvassing remains a powerful commercial tool, but its legal framework has never been stricter. Between GDPR, French telephone canvassing law, and the Bloctel system, companies must navigate a complex regulatory environment. Here's what you absolutely need to know in 2026.
GDPR Applied to Telephone Canvassing
Legal Bases for Calling a Prospect
The General Data Protection Regulation (GDPR) requires a legal basis for any processing of personal data, including the use of a phone number for commercial purposes. Two legal bases are mainly used for telephone canvassing:
1. Explicit Consent
This is the most legally solid basis. The person has given their prior, free, specific, and informed agreement to be contacted. This consent must be:
- Free: no pressure or negative consequences in case of refusal
- Specific: clearly linked to the prospecting activity
- Informed: the person knows exactly what they are consenting to
- Unambiguous: a clear positive action (checkbox, signature...)
2. Legitimate Interest
For existing customers only, the company can invoke its legitimate interest in recontacting them. According to the CNIL, this legal basis is acceptable for "commercial prospecting operations towards a company's customers."
Information Obligations
Each telephone solicitation must allow the contacted person to:
- Know the identity of the calling organization
- Object simply and free of charge to new calls
