How to Get All Contact Data from Google Maps: A Complete Step-by-Step Guide

🧭 Introduction

If you’ve ever tried reaching out to businesses found on Google Maps — whether to offer a service, initiate a collaboration, or build a lead list — you probably know how time-consuming and inefficient the process can be.

Clicking into each listing, visiting their website, searching for email addresses or WhatsApp numbers — all of that adds up. It works for 5 or 10 contacts… but what about 500?

This article walks you through:

  • How to get contact information from businesses listed on Google Maps
  • Common manual and semi-automated techniques
  • Website research tips to uncover hidden emails
  • And most importantly, how KorpDeck automates this entire process using just a keyword, city, and country — all in one platform.

🔍 What contact details can you extract from Google Maps?

From a public Google Maps listing, you can usually access:

  • Business name
  • Physical address
  • Phone number
  • Website (if listed)
  • Opening hours
  • Customer reviews
  • Business category

However, email addresses are rarely shown directly in Google Maps listings. That’s why many people resort to deeper manual research, which we’ll explore next.


🧰 Common methods to gather contact data from Google Maps

1. Manual lookup (one by one)

The classic DIY approach:

  1. Search on Google Maps (e.g. “coffee shops in Chicago”)
  2. Open each business profile
  3. Copy phone number or address
  4. Visit the listed website
  5. Find email address or contact form on their page

💡 Example:

You search “legal consulting firms in Toronto.”
You find “MapleLaw Advisors.”
Their Google Maps profile links to maplelaw.ca.
You visit the site and locate their email: contact@maplelaw.ca.

This works fine if you only need 10 leads. But what if you want 100? Or 1,000? It quickly becomes exhausting.


2. Browser extensions and plugins

There are several Chrome extensions that try to help with this:

  • Data Miner
  • Instant Data Scraper
  • LeadLeaper

They can extract visible business lists, but they have limits:

  • They don’t visit or analyze the actual websites
  • They can’t check for WhatsApp availability
  • They’re not designed to filter by city/country or export clean data sets

3. Manual website research (email hunting)

Once you have the website URL from Google Maps, you can:

  • Use tools like hunter.io or Email Extractor
  • Manually check pages like /contact, /about, /team, etc.
  • Look at metadata, footers, or even open-source files like:
    • sitemap.xml
    • robots.txt
    • humans.txt

You can also use Google Dorking:

site:maplelaw.ca “@gmail.com” OR “@maplelaw.ca”

This surfaces indexed email addresses from Google’s database — but again, it’s manual and slow.

This method is ideal for:

  • Marketing agencies looking for new clients
  • Sales reps doing outbound B2B outreach
  • Freelancers offering web, design, or consultancy services
  • Startup founders launching niche SaaS or local solutions
  • Software companies targeting physical businesses (e.g., appointment tools, CRMs, booking systems)

📌 Tips to improve your results

  • Use specific keywords like “event planner,” “orthodontist,” “dog groomer”
  • Combine city + country filters to avoid irrelevant results
  • Focus on businesses with WhatsApp active for better direct outreach
  • Clean your email list before starting any cold campaign
  • Use custom messages — don’t spam generic templates
