3 Levels of Geocoding Accuracy: Rooftop, ZIP+4, and ZIP Code
GeoCoder provides latitude and longitude geographic coordinates, census tract and block numbers, as well as county name and FIPS numbers.
1. Rooftop Level Geocoding
Rooftop Level Geocoding translates addresses into latitude and longitude coordinates to know exactly where they are, on a map, in a neighborhood. As the highest level of geocoding available, the accuracy literally comes down to your customer’s front door. The ideal solution for insurance and tax jurisdictions, risk exposure analysis, and delivery routing, Rooftop Level Geocoding is the most precise you can get.
So, how do we do it? Accurate geocoding algorithms are the key to location intelligence. Because address databases are often filled with errors, typos, and inconsistencies, it’s sometimes difficult to match stored data with actual coordinates. Melissa combs through 195 million individual addresses and utilizes precise mathematical location algorithms and street shape maps to select the best recorded point. GeoCoder incorporates data from multiple sources, including spatial data, navigational data, and census data. All sources are evaluated and intelligently merged to produce the most precise coordinates possible.
2. ZIP+4® Geocoding
The next level of accuracy is to the ZIP+4 – which includes an area of about 10-20 households. Even though ZIP+4 geocoding validates the address data with slightly less accuracy than the rooftop level, you can still easily spot demographic and segmentation patterns to target your customers more effectively and power store locators for your business.
3. ZIP Code™ Geocoding
The broadest range of geocoding is ZIP Code level, which can show you the geographical area and city boundaries. ZIP Codes at this level are mainly used for USPS® sorting, but it can also help you see the general area where your customers are located to plan local or geographic-based marketing campaigns. With ZIP Code level geocoding, you’ll see coordinates usually within a few miles.
International Geocoding
Melissa offers accurate address geocoding for over 240+ countries worldwide. The output points can be visualized on a map, inserted as stops for a route, or loaded as input for spatial analysis. Because addresses around the world are not all the same, the best way to ensure you’re getting reliable geocodes is to utilize Melissa address verification at the same time to ensure your data is accurate and the addresses are real.

Reverse Geocoding
Reverse geocoding works like regular geocoding—but it takes latitude and longitude and converts it to a mapped address. Image you have a GPS signal with latitude and longitude coordinates, and you want information about the place represented at this address. Imagine that with this information, you get the latest TIGER® address data, sourced from the U.S. Census Bureau®, for the most accurate geocodes and specific location facts like house number, city, state, ZIP Code™, FIPS code, and more.
