RGPD, SIREN Registry, and What Makes French Data Different

The CNIL (France's data protection authority) is one of Europe's most active regulators — it has issued significant GDPR fines against both US tech companies and French firms. For B2B outbound, legitimate interests is the standard lawful basis, but CNIL requires documented opt-out processes and prompt suppression of removal requests. French outbound compliance is not a formality.

On the data side, France has a structural advantage most people overlook: the SIREN and SIRET registry. Every French company has a SIREN number (9 digits) and every establishment has a SIRET (14 digits), both maintained by INSEE. Providers that source from this registry — most notably Dropcontact — can verify that an email belongs to a legitimate, active French company establishment before you ever send it.

This SIREN-level company matching is why Dropcontact is the highest-accuracy email enrichment tool specifically for French companies, even though it is less known than global providers. The registry verification step eliminates bounce rates that come from defunct companies or recent job changes.

1. SyncGTM

SyncGTM delivers French contact enrichment through waterfall cascading across 50+ providers. For French contacts — where a single provider often covers large Paris-based enterprises well but misses regional SMEs — the waterfall approach maximizes fill rates by trying multiple sources per contact.

The buying signals layer monitors French target accounts for Series A/B/C funding rounds (the French tech ecosystem is active: Station F alumni, BPI France-backed companies), executive hires, and hiring surges — timing intelligence that static French databases don't provide.

• Waterfall enrichment for higher French contact fill rates
• Buying signal monitoring across French target accounts
• Native HubSpot/Salesforce CRM sync
• Free tier available
• Starting price: $99/mo

2. Cognism

Cognism is the strongest choice for French phone-verified contacts. Their Diamond Data tier provides human-verified mobile numbers — particularly valuable in France where direct switchboard numbers are difficult to obtain and mobile-first outreach is increasingly the norm for B2B sales.

RGPD compliance documentation is built into the product. Cognism maintains suppress lists against EU opt-outs and provides legitimate interests documentation for customers. For French enterprise outreach where compliance scrutiny is high, Cognism is the defensible choice.

• Diamond Data: human-verified French mobile numbers
• RGPD compliance documentation and DNC list management
• Strong France/European focus
• Starting price: Custom — contact for pricing

3. Apollo.io

Apollo.io covers French contacts reasonably well — particularly for Paris-based companies in fintech, SaaS, and professional services. The free tier and $49/mo starting price make it the logical first stop for teams testing French outreach before committing to enterprise pricing.

Direct dials for French contacts are inconsistent — Apollo's mobile numbers are aggregated rather than verified. For email-first French outreach, Apollo delivers solid email accuracy at accessible pricing.

• Good French email coverage for Paris and tech hubs
• Free plan: 50 email credits/mo
• RGPD compliance framework available
• Starting price: $49/mo

4. Lusha

Lusha is useful for individual French contact lookups while prospecting on LinkedIn. French tech, finance, and consulting contacts in Paris and Lyon are reasonably represented. For systematic French list building, the credit-per-contact model gets expensive quickly.

• Chrome extension for LinkedIn-based French contact lookups
• Free tier: 50 credits/mo
• RGPD compliance claims — verify with your legal team
• Starting price: $49/mo

5. ZoomInfo

ZoomInfo has substantial coverage of large French enterprises — CAC 40 companies, major financial services groups, and multinational French subsidiaries. French SME and regional company coverage is thinner. The enterprise-only pricing structure ($15k+/yr) makes it difficult to justify for France-specific prospecting unless France is one of many markets in a global program.

• Large French enterprise and CAC 40 coverage
• Intent data via Bombora
• Enterprise contracts only
• Starting price: $15k+/yr

6. Kompass

Kompass is a France-founded B2B data platform with particularly strong coverage of French SMEs and industrial companies. While global platforms tend to over-index on tech and financial services, Kompass covers manufacturing, trade, and regional French companies that other databases miss.

The data is SIREN-linked and includes company classification codes (NAF codes) — useful for precise sector targeting that isn't possible with generic industry tags. Coverage is strongest for France; their European data quality varies by country.

• SIREN-linked French company data
• Strong SME and industrial sector coverage
• NAF code filtering for precise sector targeting
• Starting price: Custom — contact for pricing

7. Société Info

Société Info (societe.com) is a France-native business intelligence platform built on top of the SIREN/SIRET registry. It provides financial data, company registration details, and director information for all French companies — making it the most reliable source for French company-level research.

Société Info is primarily useful for company-level intelligence, not personal contact data. Use it to identify companies, research financials, and find directors — then enrich with personal contact data from a specialist provider.

• Full SIREN/SIRET registry coverage
• Financial data, Kbis extracts, and director information
• Freemium model for basic company lookup
• Starting price: Custom for API/bulk access

8. Leadinfo

Leadinfo identifies anonymous website visitors and matches them to company data — including French companies. Rather than outbound prospecting, Leadinfo's model is inbound: see which French companies are visiting your website, then enrich and route them to your sales team.

This is a different use case than a contact database — but for teams with meaningful French website traffic, Leadinfo converts anonymous visits into actionable leads.

• French website visitor identification
• Company-level enrichment for identified visitors
• CRM and marketing automation integrations
• Starting price: ~€65/mo
