Real estate address data is notoriously messy. Bring it on.
Got misspelled streets, missing zip codes, and garbled unit numbers? Geocodio cleans it all up and adds coordinates, school districts, Census geographies, and more.
Real estate data arrives from dozens of sources. MLS feeds, county records, title companies, property management systems. Each one formats addresses differently, and none of them are consistent.
"100 West Main Street" in one feed is "100 W Main St" in the next. Unit numbers show up in the wrong field. ZIP codes are missing. Street names are misspelled. And you need all of it to match before you can do anything useful with it.
- Clean, standardize, and enrich in one step. Send Geocodio an address in whatever shape it arrives and get back a corrected, standardized version with coordinates, school districts, Census geographies, and more. One request. All the data.
- Deduplicate with confidence. Geocodio's Stable Address Keys, included for free with every result, give every address a persistent unique identifier. When the same property shows up in three different MLS feeds with three different formats, the key stays the same. No more matching on ZIP + street name + hope.
- Build around the data, not around the gaps. Geocodio powers thousands of real estate applications, from home search apps to property valuation models to investment analysis tools. Coordinates, school districts, Census tracts, average household income, and more. All available via API or spreadsheet upload.
The data your real estate application needs.

Mistyped, misspelled, and missing address fields are our specialty. We'll take your messy addresses, correct them, and return them to you nice and neat.
Stable Address Keys
Quickly de-dupe addresses using our persistent unique identifier for every address. Match properties across MLS feeds, data vendors, and time without brittle address-string matching.
Coordinates
Rooftop-level latitude and longitude for radius searches, polygon matching, map display, and distance calculations.
Timezone
Know the local time for any property. Useful for scheduling, buyer communication tools, and fleet coordination.
School Districts
Buyers care about schools. With Geocodio, you can append school district names, IDs, and grade levels to any address.

Best of all?
With Geocodio, there are no restrictions on storing or reusing results.
So you can stop paying to re-geocode the same data every month after your geocoder's 30-day cache expires...or worrying that they'll shut you down when they discover that you're storing the data in violation of their terms.
From "AAH!" to "ahh."
From "AAH!" to "ahh."
Address Completion
Missing pieces like county name, postal code, or more? Geocodio can add them.
Even if you've only got "100 East Main, 21157," we complete it to "100 East Main St, Westminster MD 21157". We can even add county data (Carroll County, in this case).
Address Correction
Real-world addresses come with typos, missing fields, and creative formatting.
From misspelled street names to incorrect postal codes, Geocodio can correct and complete your addresses. (Go ahead. Try us.)
Address Parsing
Geocodio separates each address into its component parts and lines, even if the address arrives in one big lump.
For instance, Geocodio knows that "Apt 5A" in the address "100 East Main St Apt 5A" should be split into the Address 2 line.
Address Standardization
Missing county name, postal code, or ZIP+4? Geocodio fills in the gaps.
Even if all you have is "100 East Main, 21157," Geocodio completes it to "100 East Main St, Westminster, MD 21157" with Carroll County included.

"Geocodio has been an absolute lifesaver in streamlining my workflow...The platform has consistently delivered precise geocoding results, which is essential for making informed decisions regarding site selection and market analysis."
SimplyRETS SimplyRETS is a platform that helps developers, agents, and brokers build real estate applications and websites using listing and market data from their local MLS.
"The Geocodio API has been extremely stable and accurate. We've had virtually zero downtime in years and it has maintained backwards compatibility the whole time. For the price point, it's an incredible deal and saves our developers a ton of time."
Christopher Reichert, Co-Founder & Director of Development
SimplyRETS
Who They Are
SimplyRETS needed reliable geocoding and address standardization for millions of real estate listings across the US and Canada.
The team syncs a large number of real estate feeds on behalf of agents, brokers, and technology companies building real estate tools across the United States and Canada.
In regions where accurate coordinate data for addresses is not available from MLS feeds, SimplyRETS integrates geocoding to fill in the gaps.
The Challenge
Before Geocodio, the SimplyRETS team tried several approaches to handle geocoding in-house.
They bootstrapped entire TIGER data sets into PostGIS, experimented with Nominatim, and evaluated several commercial options. The self-hosted solutions required significant developer time to set up and maintain.
The commercial alternatives were either too expensive or had a poor developer experience that cost the team even more time working around limitations, such as data storage restrictions.
The Solution
SimplyRETS chose Geocodio for its user experience, affordability, and ease of use.
Instead of maintaining their own geocoding infrastructure or fighting with clunky commercial APIs, the team could focus on building their core product.
And unlike many other commercial solutions, Geocodio allows them to store the data in their database without restrictions.
The Results
"The Geocodio API has been extremely stable and accurate," says Christopher. The team has experienced virtually zero downtime over years of use, and backwards compatibility has meant no surprise breaking changes to work around. For a team managing a large volume of real estate feeds, that reliability translates directly into less maintenance and more time spent on features their customers care about.
