GDPR and Google Maps Data: What's Legal for B2B Lead Generation

The Question Every B2B Team Asks

Is it legal to extract business contact information from Google Maps and use it for cold outreach?

The short answer is: for B2B outreach targeting businesses (not individuals), using publicly available business contact data, yes—with appropriate practices in place.

The longer answer requires understanding what GDPR actually regulates, what "legitimate interest" means, and how the data source (official vs. scraped) affects compliance risk.

This guide covers the practical compliance framework for B2B teams using Google Maps data for lead generation in Europe.

What GDPR Regulates (and What It Doesn't)

GDPR regulates the processing of personal data—information relating to an identified or identifiable natural person.

Business contact data sits in a nuanced position:

Clearly covered by GDPR:

• An individual's personal email address (john.smith@gmail.com)
• A mobile phone number used for personal purposes
• A sole trader's personal information (sole traders are treated as individuals under GDPR)

Generally not covered (or lower risk) under GDPR:

• A business's trading name
• A registered business address
• A business phone number listed on a public directory
• A generic business email address (contact@businessname.com)

The ICO (UK), CNIL (France), and most European data protection authorities have confirmed that business contact information used for legitimate B2B marketing is generally permissible under GDPR's legitimate interest basis.

The Legitimate Interest Basis

GDPR Article 6(1)(f) allows processing of personal data where it is "necessary for the purposes of the legitimate interests pursued by the controller or by a third party, except where such interests are overridden by the interests or fundamental rights and freedoms of the data subject."

For B2B outreach, the typical legitimate interest argument is:

1. Your interest: Finding customers for your product or service
2. Their interest: Discovering products or services that could benefit their business
3. Balancing test: The processing (contacting a business about relevant services) is unlikely to cause significant harm to the business or its owner

This argument holds most strongly when:

• You're targeting businesses, not individuals in their personal capacity
• The contact data is professional (business phone, business email)
• Your offer is genuinely relevant to the type of business you're contacting
• You include a clear opt-out mechanism
• You honor opt-out requests immediately

It's weakest when:

• You're targeting sole traders (who are personally identifiable)
• You're using personal email addresses
• Your offer has no relevance to the recipient's business type
• You ignore opt-out requests

Official Data vs. Scraped Data: Why It Matters for Compliance

Not all Google Maps data is equal from a compliance perspective.

Scraped data (extracted from Google's web interface by parsing HTML):

• May include data that Google itself sourced from third parties
• The data provenance is unclear
• Using it potentially violates Google's Terms of Service
• May create additional GDPR exposure if the scraping was unauthorized

Official channel data (accessed via Google's published APIs and official data channels):

• Clear provenance: Google is a legitimate, GDPR-compliant data controller
• Google's business listings are public data that businesses themselves submitted
• No Terms of Service violation
• Cleaner compliance position

MapsLeads uses official Google data channels, which eliminates the ToS violation risk and provides clearer data provenance for compliance purposes.

Practical Compliance Checklist for B2B Google Maps Outreach

Before you build your list:

☐ Define your targeting criteria — You need a documented basis for why you're contacting each business type. "We sell restaurant software to restaurants" is a clear legitimate interest.

☐ Use business contact data only — Avoid personal email addresses. business@company.com and contact@company.com are appropriate. personal.name@gmail.com is not.

☐ Use an official data source — Tools like MapsLeads that access official Google channels provide cleaner compliance than scrapers.

In your outreach:

☐ Include your company name and contact details — Every communication must identify who is contacting them and why.

☐ Include an opt-out mechanism — "Reply STOP to be removed" or an unsubscribe link in every email. For phone calls, note the request and remove from your list.

☐ State why you're contacting them — "I'm reaching out because you operate a dental practice in [City] and we work with dental practices on..." provides the legitimate interest context.

☐ Honor opt-out requests immediately — Remove opted-out contacts from all future campaigns. Maintain a suppression list.

Record keeping:

☐ Document your legitimate interest assessment — A brief written record of your legal basis for contacting each business category.

☐ Keep suppression lists — Records of who has opted out, to prevent re-contacting.

Country-Specific Notes

France (CNIL): The CNIL has specific guidance on B2B prospecting. Business email addresses (contact@, info@) used for B2B purposes are generally permitted under legitimate interest. The recipient must be able to object, and the data must be used for purposes "in connection with their professional activities."

Germany (BDSG + GDPR): Germany applies GDPR with some additional national rules. B2B cold email requires an existing business relationship or the prospect must have "declared consent." German cold outreach is more conservative and phone outreach is generally preferred.

UK (post-Brexit PECR + UK GDPR): The Privacy and Electronic Communications Regulations (PECR) apply to marketing communications. For B2B email, PECR allows marketing to corporate subscribers (companies) with opt-out. Sole traders are treated as individuals. The ICO confirms that B2B marketing to corporate email addresses is generally permissible.

Spain and Italy: Both follow standard GDPR rules with no significant additions that affect standard B2B outreach practices.

The Bottom Line

B2B lead generation using Google Maps business data is legally permissible in most European jurisdictions when:

1. You target businesses, not individuals in their personal capacity
2. You use business contact data (not personal emails or mobile numbers)
3. Your offer is relevant to the businesses you're contacting
4. You provide opt-out and honor requests
5. You use data from legitimate sources (not unauthorized scraping)

For most B2B outreach scenarios—targeting restaurants, dental practices, law firms, contractors, or other local businesses with relevant offers—the compliance risk is low when these practices are followed.
