Batch Geocoding - Convert Addresses to Lat Long in Bulk

What is Batch Geocoding?

Batch geocoding is the process of converting large numbers of addresses into geographic coordinates (latitude and longitude) in a single operation. Instead of geocoding addresses one at a time, batch processing allows you to handle thousands or millions of records efficiently.

Common Batch Geocoding Use Cases

Data Migration: Add coordinates to existing address databases
CRM Enhancement: Geocode customer addresses for territory mapping
Real Estate: Process property listing addresses in bulk
Logistics: Prepare delivery addresses for route optimization
Analytics: Enable geographic analysis of address data

How to Batch Geocode with LatLng

Process your addresses efficiently using parallel API requests:

Python Example

Python

import asyncio
import aiohttp

async def geocode_address(session, address, api_key):
    url = f"https://api.latlng.work/geocode?q={address}&api_key={api_key}"
    async with session.get(url) as response:
        return await response.json()

async def batch_geocode(addresses, api_key):
    async with aiohttp.ClientSession() as session:
        tasks = [geocode_address(session, addr, api_key) for addr in addresses]
        return await asyncio.gather(*tasks)

# Process 100 addresses in parallel
addresses = ["123 Main St, NYC", "456 Oak Ave, LA", ...]
results = asyncio.run(batch_geocode(addresses, "YOUR_API_KEY"))

Best Practices

Use parallel requests (10-50 concurrent) for best performance
Implement retry logic for failed requests
Cache results to avoid re-geocoding duplicates
Clean and standardize addresses before geocoding
Monitor your rate limits in the dashboard
