Global Address Database (GAD) Reference Data

Get accurate and detailed information on every address in the U.S., Canada and, many other countries

The Global Address Database (GAD) contains accurate and detailed information on every address including non-post office addresses (i.e. physical address that the Post Office does not deliver to). In addition to street addresses (including apartment/suite numbers), MAT also provides geographic information like rooftop latitude-longitude coordinates, census tract/block number, and county name with FIPS code – ideal for analytics, mapping, risk management and logistics applications.

The “Key” Makes MAT Unique

Each U.S. and Canadian address is assigned a Melissa Address Key (MAK), which is a 10-digit number that never changes. Much like a barcode or ISBN, this address key identifies a discrete physical address and aligns a multitude of additional information associated with the address. When you purchase MAT, you have all of the valid addresses within a given area – and no matter how the addresses change, or if new addresses become available, you know exactly what the changes are.

Geocoding & Location Intelligence - 3 Levels of Geocoding Accuracy: Premise, ZIP+4, and ZIP Code

You can select the search parameters to fit your needs. For instance, get all the addresses associated with a congressional district, ZIP Code, group of ZIP Codes, City, County, State or any shape-based search.

How to Use MAT

MAT is a boon to the first responder community – imagine a complete database of all residential and business addresses that is up-to-date and easily accessible by fire departments or 911 emergency call centers to quickly identify an address and ensure help reaches the correct location immediately.
