Special requirements
Telemarketing regulations (effective August 11, 2026): A new French telemarketing law takes effect on this date and imposes the following restrictions on marketing calls:
- Opt-in consent required: Organizations must obtain consumer consent before placing any marketing call. Consent must be explicit, specific to the purpose, and compliant with GDPR.
- Restricted calling windows: Marketing calls are permitted only Monday through Friday, 10:00 a.m.–1:00 p.m. and 2:00–8:00 p.m. local time. Calls are prohibited on weekends and public holidays.
- Proof of consent required: If a consumer has consented to be contacted at a specific date and time, the organization must be able to certify precisely when that consent was given and what time was agreed.
- Existing-contract exception: Marketing calls that relate directly to an existing contract with the consumer are exempt from the opt-in and calling-window restrictions above.
Energy efficiency solicitation ban (effective July 1, 2025): Organizations are prohibited from contacting customers by phone, SMS, email, or online social networking service to offer services, sell equipment, or carry out work related to housing for the purpose of energy savings, renewable energy production, or adapting housing for aging or disability. This ban applies regardless of any prior consent and covers all listed channels, not phone calls alone.
