Scraping Phone Numbers on Google Maps: Complete Guide

Google Maps hosts over 200 million business listings. Each contains valuable data: phone numbers, addresses, hours, customer reviews. For salespeople, prospectors, and agencies, quickly accessing this information can transform a business strategy.

But extracting manually? Impossible at scale. This article shows you how to effectively scrape phone numbers from Google Maps — while respecting legality.

Why Extract Phone Numbers on Google Maps?

Google Maps is not just a navigation app. It's a living business directory where companies publish their contact information, reviews, and hours.

Concrete use cases:

• B2B Prospecting: Build a list of plumbers, electricians, restaurants in a given area
• Competitive Analysis: Identify competing businesses and their contact details
• Lead Generation: Create a database of qualified prospects by geographic area
• Market Research: Analyze the density of businesses by category in an area

According to Google, Google Maps facilitates over 4 billion monthly connections between customers and businesses (calls, directions, messages). This audience is massive — and the data it generates is valuable.

The real question is not "should I extract this data?", but "how to do it efficiently and legally?".

Different Methods to Scrape Google Maps

There are three main approaches. Each has its advantages and limitations.

1. Manual Extraction

Process: 1. Open Google Maps 2. Search for a category of businesses (e.g., "plumbers in Lyon") 3. Click on each listing 4. Copy the phone number 5. Paste into an Excel sheet

Advantages: - Zero legal risk - No tools to install - You control exactly which data you take

Disadvantages: - Extremely slow (15-20 seconds per listing) - For 1,000 businesses = 4-5 hours of work - Input errors - No automatic updates

Verdict: Acceptable for < 50 listings. Beyond that, it's a waste of time.

2. Chrome Extensions and No-Code Tools

Extensions like "Google Maps Extractor" or web tools allow scraping without writing a line of code.

How it works: - You install the extension in Chrome - You launch a Google Maps search - The tool automatically scrapes the results - You download a CSV file

Advantages: - Fast (500 listings in 5-10 minutes) - No technical skills required - No API to configure

Disadvantages: - Variable quality depending on the tool - Risk of IP banning (Google detects automated requests) - Sometimes incomplete or poorly formatted data - Maintenance: the extension breaks if Google changes its interface - Rate limits (Google blocks after X requests)

Verdict: Useful for one-off extractions, but unreliable at scale.

3. Specialized Tools with API

Platforms like IBLead or Apify offer a pre-indexed database or a dedicated API.

How it works: - The database is already filled (updated monthly) - You filter by city, category, rating, etc. - You export to CSV - The data includes phone numbers, emails, addresses, reviews, detected technologies

Advantages: - Maximum reliability (no IP blocking) - Complete and cleaned data - Automatic updates - Advanced filters (Google rating, number of reviews, claimed listing, etc.) - Technical support - Guaranteed legal compliance

Disadvantages: - Cost (from €44/month) - Dependence on a provider

Verdict: The best solution for professional prospectors.

Understanding Web Scraping on Google Maps

What is Web Scraping?

Web scraping (or data extraction) involves automatically retrieving information from a website. The extracted data can be text, images, links, or contact details.

Simple example:

URL: https://maps.google.com/search/plombiers+Lyon
Extracted data:
- Name: "Plomberie Martin SARL"
- Phone: "+33 4 72 XX XX XX"
- Address: "123 Rue de la Paix, 69000 Lyon"
- Rating: "4.8 stars"
- Reviews: 47 reviews

Why Google Maps Interests Scrapers?

1. Public Data: The information on listings is visible to everyone
2. Massive Volume: 200M+ listings = huge database
3. Structured Data: Each listing follows the same format (name, phone, address, etc.)
4. Constant Updates: Businesses regularly update their information
5. Few Alternatives: It's the most comprehensive business directory in France

How Does Technical Scraping Work?

Step 1: Identifying Elements The tool analyzes the HTML code of the Google Maps page and locates where the phone numbers are (HTML tags, CSS classes, etc.).

Step 2: Extraction The tool retrieves the content of these elements.

Step 3: Cleaning The raw data is formatted (removing spaces, normalizing numbers, etc.).

Step 4: Storage The data is saved in CSV, JSON, or directly in a database.

Legal Risks of Web Scraping

This is the question all prospectors ask: "Is it legal?"

The answer: It depends.

GDPR (General Data Protection Regulation)

The GDPR applies to all processing of personal data in Europe.

Personal Data = any information that can identify a person (phone number, email, name).

Key Rules: - You can only collect data for a legitimate purpose (prospecting = legitimate) - You must respect the right to object (if someone says "don't call me", you must stop) - You must have a legal basis (consent, legitimate interest, legal obligation)

For B2B Prospecting: The GDPR applies less strictly. Professional phone numbers of businesses are less protected than personal data.

Advice: Use the data to contact the business (main number), not specific individuals.

Google Maps Terms of Use

Google explicitly prohibits automated scraping in its terms of use. But: - Google generally does not pursue individuals (it's costly) - Google rather blocks technically (IP banning, captcha) - Professional tools bypass this through legal APIs or pre-indexed databases

Legal Solution: Use a Pre-Indexed Database

Instead of scraping Google Maps in real-time (risky), you can use a legally updated pre-indexed database.

This is IBLead's approach: the database is indexed once, updated monthly, and you access it through a web interface. Zero real-time scraping, zero risk of blocking.

Practical Guide: How to Scrape Phone Numbers

Here is the complete process, step by step.

Step 1: Define Your Search

Before scraping, ask yourself: - What category of businesses? (plumbers, restaurants, real estate agencies, etc.) - What geographic area? (city, region, country) - What volume? (100 listings, 10,000?) - What quality criteria? (minimum rating, number of reviews, claimed listing, etc.)

Example:

Category: Plumbers
Area: Lyon (69000-69009)
Volume: 500 listings
Criteria: Rating ≥ 4 stars, ≥ 10 reviews, claimed listing

Step 2: Choose Your Tool

If you have < 50 listings: Manual extraction (Excel)

If you have 50-500 listings and it's one-off: Chrome extension (risky but fast)

If you have > 500 listings or recurring: Professional tool (IBLead, Apify)

Step 3: Launch the Extraction

With a Chrome extension: 1. Install the extension in Chrome 2. Go to Google Maps 3. Search for "plumbers in Lyon" 4. Click the "Scrape" button of the extension 5. Wait (5-10 minutes for 500 listings) 6. Download the CSV

With a professional tool (example IBLead): 1. Create a free account (200 credits included) 2. Go to the app (app.iblead.com) 3. Select "Plumbers" in the categories 4. Filter by city (Lyon) 5. Add advanced filters (rating ≥ 4, ≥ 10 reviews) 6. Click "Export" 7. Download the CSV in 30 seconds

Step 4: Clean and Validate the Data

The raw data often contains errors or duplicates.

Checks: - Poorly formatted phone numbers? (e.g., "+33 4 72 XX XX XX" vs "0472XXXXXX") - Duplicates? (same business listed twice) - Missing data? (business without a phone) - Closed or duplicate businesses?

With Excel:

1. Remove empty rows
2. Use "Remove Duplicates" (Data > Remove Duplicates)
3. Format numbers (e.g., =REGEX to normalize)
4. Sort by rating/number of reviews to identify outliers

Step 5: Use the Data

Phone Prospecting: - Call the main number directly - Prepare a short script (30 seconds) - Introduce yourself and offer your service

Email Prospecting: - Combine the number with the email (if available) - Use a cold email tool (Lemlist, Instantly) - Create a segmented campaign by category

CRM Integration: - Import the CSV into Salesforce, HubSpot, Pipedrive - Create prospect lists - Assign to your sales team
