What is Google Maps Plus Code and How Do You Find It?

#webdev #programming #javascript #ai

Google Maps Plus Code is an open-source geocoding system developed by Google that represents precise locations using short alphanumeric codes. Unlike traditional addresses that rely on street names and numbers, Plus Codes work everywhere on Earth, including areas without formal addressing systems. After working with location data across dozens of projects, I've found Plus Codes to be one of the most underutilized yet powerful tools in the Google Maps ecosystem.

This guide explains what Plus Codes are, how they work, how to find them, and why they matter for businesses working with location data.

How Plus Codes Work

Plus Codes encode geographic coordinates (latitude and longitude) into a compact, human-readable format. A typical Plus Code looks like this: 849VCWC8+R6.

The system divides the entire planet into a grid of cells. Each cell gets a unique code:

  • Longer codes represent more precise locations
  • A 10-character code identifies a location within approximately 14 square meters
  • A shorter code (with a reference location) can identify areas within a few thousand meters
  • Codes use only alphanumeric characters (no ambiguous characters like O, I, or L)

Plus Code Structure

Component Example Purpose
Full Code 849VCWC8+R6 Precise location (14m² accuracy)
Shortened Code WC8+R6 Relative to a known reference area
Area Code 849VCWC8 Identifies a larger region

How to Find a Plus Code

Method 1: Google Maps App

The easiest way to find a Plus Code is through the Google Maps mobile app:

  1. Open Google Maps on your phone
  2. Tap and hold on any location on the map
  3. A red pin appears with the location details
  4. Scroll down to find the Plus Code listed alongside the address and coordinates
  5. Tap the Plus Code to copy it

Method 2: Google Maps Desktop

On desktop browsers:

  1. Go to Google Maps
  2. Right-click on any location
  3. The Plus Code appears in the info card
  4. Click to copy

Method 3: Google Maps API

For programmatic access, the Google Maps Geocoding API returns Plus Codes in API responses:

import requests

def get_plus_code(address):
    """
    Retrieve Plus Code for a given address using Google Maps API
    """
    api_key = "YOUR_API_KEY"
    url = f"https://maps.googleapis.com/maps/api/geocode/json"
    params = {
        "address": address,
        "key": api_key
    }
    response = requests.get(url, params=params)
    data = response.json()

    if data["results"]:
        plus_code = data["results"][0].get("plus_code", {})
        return plus_code.get("compound_code", "Not available")
    return "Location not found"

# Example usage
print(get_plus_code("Times Square, New York"))
Enter fullscreen mode Exit fullscreen mode

Method 4: Plus Code Open Source Library

Google provides an open-source library for encoding and decoding Plus Codes without requiring an API key:

# Install: pip install pluscodes
import pluscodes

def encode_location(latitude, longitude):
    encoder = pluscodes.PlusCode()
    return encoder.encode(latitude, longitude)

def decode_plus_code(code):
    decoder = pluscodes.PlusCode()
    return decoder.decode(code)

# Encode coordinates to Plus Code
code = encode_location(40.7580, -73.9855)
print(f"Plus Code: {code}")

# Decode Plus Code to coordinates
coords = decode_plus_code("849VCWC8+R6")
print(f"Lat: {coords[0]}, Lng: {coords[1]}")
Enter fullscreen mode Exit fullscreen mode

Why Plus Codes Matter for Business

For Data Collection and Scraping

Plus Codes offer significant advantages for businesses collecting location data from Google Maps:

  • Universal addressing: Works for locations without street addresses
  • Consistent format: No parsing variations across countries
  • Machine-readable: Easy to store, sort, and compare
  • Precision control: Code length determines accuracy level
  • No API dependency: Can be generated offline using coordinates

For Logistics and Delivery

Companies like Uber, DoorDash, and logistics providers use Plus Codes because:

  • They pinpoint exact pickup and drop-off locations
  • They work in areas with poor addressing (construction sites, new developments)
  • They integrate seamlessly with mapping applications
  • They reduce delivery errors caused by ambiguous addresses

For Real Estate and Property

Real estate platforms leverage Plus Codes for:

  • Precise property boundary identification
  • Off-market property location sharing
  • Virtual tour positioning
  • Neighborhood analysis and mapping

For Emergency Services

Plus Codes are used by emergency response organizations because:

  • They work in areas without named streets
  • They can be communicated quickly over radio or phone
  • They provide precise location without needing landmarks
  • They are language-independent

Plus Codes vs Traditional Coordinates

Feature Plus Codes Lat/Lng Coordinates Street Addresses
Human Readable Partially No Yes
Machine Readable Yes Yes No
Universal Coverage Yes Yes No
Precision Control Yes (code length) Yes (decimal places) No
Offline Generation Yes Yes No
Area Reference Yes (short codes) No Yes (neighborhood)
Address Gaps No gaps No gaps Major gaps

Extracting Plus Codes at Scale

For businesses that need to collect Plus Codes for thousands of locations, manual extraction is impractical. Managed data services like CoreClaw can automate this process, extracting Plus Codes alongside other Google Maps business data including names, addresses, phone numbers, and reviews.

CoreClaw handles the technical complexities of large-scale extraction, including rate limiting, data normalization, and scheduled updates. Pricing starts at $99/month for basic location data packages.

For developers who prefer a DIY approach, the open-source pluscodes library combined with Google Maps coordinate data provides a cost-effective alternative, though it requires ongoing maintenance as APIs and data formats evolve.

Common Use Cases

Use Case 1: Lead Generation by Territory

Sales teams can use Plus Codes to define precise service territories and identify businesses within specific geographic areas. The grid-based nature of Plus Codes makes it easy to create systematic coverage plans.

Use Case 2: Location-Based Marketing

Marketers can use Plus Codes to target advertising and promotions to specific geographic areas, even in regions without traditional addressing systems.

Use Case 3: Asset Tracking

Businesses with distributed physical assets (equipment, vehicles, infrastructure) can use Plus Codes to record and track precise locations without relying on street addresses.

Use Case 4: Data Enrichment

Existing business databases can be enriched with Plus Codes by geocoding street addresses, enabling geographic analysis, proximity calculations, and map visualization.

Limitations to Consider

While Plus Codes are powerful, they have some limitations:

  • Not widely recognized by the general public
  • Cannot represent moving locations
  • Precision decreases with shorter codes
  • Limited adoption outside Google ecosystem
  • No built-in elevation or floor information

Conclusion

Google Maps Plus Codes solve a fundamental problem in location data: how to represent precise locations in a universal, machine-readable format. For businesses working with geographic data, Plus Codes offer a reliable, consistent way to identify and share locations regardless of addressing infrastructure.

Whether you're building a delivery app, collecting business leads by territory, or enriching your location database, understanding and utilizing Plus Codes can significantly improve your data quality and operational efficiency.
