8 Best Phone Number Databases for Europe in 2026 (GDPR-Compliant)

SyncGTM solves the pan-European coverage puzzle through waterfall enrichment across 50+ data providers. No single provider covers all of Europe equally: Cognism dominates UK and DACH, Dealfront excels in Northern Europe, Kaspr fills LinkedIn-sourced gaps in France and Benelux, and other providers cover Southern and Eastern European markets. SyncGTM chains them all together in a single enrichment pass.

The waterfall logic is customizable by country. You can prioritize Cognism for UK contacts, Dealfront for German companies, and regional providers for Iberian or Eastern European markets — all within one workflow. If Provider A misses a number, Provider B tries, then Provider C, through 50+ sources until the number is found or all sources are exhausted. This consistently delivers 20-40% more European phone numbers than any single provider. SyncGTM does not own phone data — it orchestrates access to other providers' datasets through one enrichment layer.

At $99/mo with no per-seat pricing, SyncGTM costs a fraction of Cognism's annual contract while querying Cognism's data alongside 49 other sources. GDPR-compliant data processing agreements are included. All enriched data syncs to HubSpot, Salesforce, Pipedrive, and Attio via native integrations. For teams selling across multiple European sub-regions without the budget for a $25,000/yr single-vendor commitment, waterfall enrichment is the pragmatic path to pan-EU phone coverage.

Cognism is the compliance benchmark for European phone data. Their DNC screening covers 30+ country-specific registries — UK TPS, CTPS, German Robinson List, French Bloctel, Swedish NIX, and dozens more. Every number in the Diamond Data program is not only screened against these registries but also human-verified: real people dial the number and confirm it reaches the intended person before it enters your dataset.

This compliance-first approach delivers a double advantage. First, your legal risk drops to near zero because every number has been screened against the relevant country's DNC list and verified as reachable. Second, connect rates are roughly 3x the industry average because you are only dialing numbers that a human confirmed work. Cognism reports 2x more European contacts than competing providers, with deep coverage across UK, DACH, Nordics, France, and Benelux.

Article 14 notification support is built in — Cognism can send data subject notifications on your behalf, which is a GDPR requirement when processing personal data obtained from third parties. Full data processing agreements, data subject access request workflows, and right-to-deletion handling are included. At $25,000/yr, Cognism costs less than a single GDPR fine. For any team making more than 50 European calls per week, the compliance infrastructure alone justifies the investment.

Dealfront is the only major sales intelligence platform built in Europe, for European selling. Formed from the merger of Leadfeeder (Finnish visitor identification) and Echobot (German company intelligence), Dealfront's entire data architecture was designed around GDPR — not retrofitted from a US-first product. This matters because GDPR compliance is structural, not a feature toggle.

DACH coverage is Dealfront's crown jewel. Echobot spent a decade building the deepest German, Austrian, and Swiss company database from official business registries, Handelsregister filings, and proprietary data partnerships. The resulting 40M+ European company records include phone data, firmographics, and technographics that no US-based provider matches for this region. The platform combines contact data with website visitor identification — see which companies visit your site and reach their decision-makers by phone.

Pricing is custom and enterprise-oriented, which puts Dealfront out of reach for most SMBs. Southern and Eastern European coverage is thinner than Cognism's, and phone numbers are not human-verified like Diamond Data. But for teams focused on DACH, Nordics, and Benelux, Dealfront offers the deepest regional intelligence. The visitor identification layer adds a unique prospecting dimension that pure data providers lack — you know exactly which companies are already interested before you pick up the phone.

Kaspr gives individual SDRs access to Cognism-grade European phone data at a fraction of the cost. As a Cognism company, Kaspr's Chrome extension pulls from the same phone-verified data pool that powers Diamond Data — but delivers it through a LinkedIn-native workflow at $49/mo instead of $25,000/yr. For reps who prospect directly from LinkedIn and need 10-40 European numbers per day, Kaspr is the sweet spot of quality and price.

GDPR compliance is inherited from Cognism's infrastructure — DNC screening, data processing agreements, and consent tracking are built in. UK, France, DACH, and Benelux phone coverage is strong. The extension integrates with LinkedIn Sales Navigator, letting you reveal phone numbers while browsing profiles, searching for prospects, or reviewing saved leads. One click to reveal, one click to export to your CRM.

The credit model limits volume: Starter at $49/mo and Business at $79/mo cap the number of reveals per month. Kaspr is not designed for bulk enrichment or API-driven workflows — it is a single-user prospecting tool. For teams of 1-5 SDRs doing targeted European outreach from LinkedIn, Kaspr delivers Cognism-level data quality at Lusha-level pricing. For teams that need hundreds of European numbers daily, Cognism or SyncGTM waterfall enrichment scales better.

Lusha provides GDPR and CCPA compliant phone data with established strength in UK and Western European markets. The Chrome extension reveals direct dials and mobile numbers from LinkedIn and company websites in one click — the same workflow as Kaspr, but with Lusha's own community-contributed data network rather than Cognism's verified dataset.

European mobile coverage is strongest for UK, France, and Benelux contacts at manager level and above. DACH coverage is growing but does not match Dealfront's depth from local business registries. Lusha's data model depends on community contributions — users share their contacts in exchange for credits — so coverage correlates with Lusha adoption in each market. Western Europe is strong; Eastern Europe and smaller markets are thinner.

GDPR compliance features include data subject access request handling, consent management, and ISO 27701 certification for privacy information management. DNC screening is available but covers fewer country-specific registries than Cognism's 30+ list. Credit pricing (Pro $49/mo for 480 credits, Premium $79/mo for 960) keeps the entry cost low. For teams that need moderate-volume European phone data with solid compliance infrastructure and do not need Cognism's full DNC screening depth, Lusha delivers reliable results at a manageable price.

Apollo.io offers the broadest European phone database at the lowest price point. Within its 275M+ global contacts, European coverage has improved significantly since 2024 — UK, DACH, and French direct dials are now competitive for standard personas (VP Sales, Head of Marketing, CTO). At $49/mo with phone credits included, Apollo is the most accessible European phone data for budget-constrained teams.

GDPR compliance meets the baseline: data deletion requests, consent management, and EU data processing agreements are supported. However, Apollo does not screen against country-specific DNC registries like Cognism does — if you use Apollo for European calling, you must manage DNC scrubbing yourself or risk violations. The "legitimate interest" basis is supported but Article 14 notifications are not automated.

For teams testing European phone outreach or adding calling to an existing email-first EMEA strategy, Apollo provides enough data to validate the channel without a large commitment. Southern and Eastern European coverage is thinner than Western Europe. If European calling proves viable, plan to layer Cognism or SyncGTM waterfall enrichment on top for compliance and coverage upgrades. Apollo is the entry ramp, not the destination.

ZoomInfo has invested heavily in European expansion since 2024, but the platform's DNA is North American. European phone coverage is growing, and the UK is now a strong market with reasonable direct dial data for enterprise contacts. The real value for European teams is consolidation: if you already use ZoomInfo for US outreach, adding EU territories avoids a second vendor relationship.

The intelligence layer — intent data, technographics, org charts — adds context that European specialists like Dealfront and Kaspr lack. A ZoomInfo user can see that a Munich-based company is researching their category, map the buying committee, and pull direct dials for three decision-makers from a single search. No European-only provider offers this depth of surrounding intelligence.

GDPR compliance is supported but not as deeply integrated as Cognism's multi-country DNC screening or Dealfront's EU-native architecture. European phone accuracy trails North American data — expect 55-65% connect rates for EU contacts versus 72% for US. At $15,000+/yr, ZoomInfo is expensive for Europe-only use. The ROI works for global teams that need unified US + EU data with intent signals. For Europe-first teams, Cognism or Dealfront offers better regional depth.

RocketReach provides reliable European phone data across 700M+ professional profiles with a bulk API for CRM enrichment. UK, DACH, France, and Benelux coverage is solid. The platform delivers direct dials, mobile numbers, and switchboard data alongside email and social profiles. For RevOps teams that need to append European phone numbers to CRM records at scale, the API is clean and well-documented.

European accuracy tested at 60-70% connect rates — below Cognism's verified numbers but reasonable for the price. RocketReach does not include built-in DNC screening or GDPR-specific compliance tooling. If you use RocketReach for European outreach, you are responsible for DNC registry scrubbing across every country you dial into. This makes RocketReach best for data-savvy teams with existing compliance infrastructure.

Essentials starts at $99/mo (80 lookups) and Pro at $199/mo (200 lookups). The per-lookup cost is higher than Apollo for volume, but the data quality is more consistent across European markets. RocketReach is a pure data utility — no dialer, no sequences, no compliance layer. For teams that want clean European phone data piped into their own compliance and outreach stack, RocketReach delivers without bundled features you do not need.
