Global Address Database (GAD)
Get accurate and detailed information on every address in the U.S., Canada and many other countries
Melissa’s 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), GAD 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.
- 190+ million U.S. addresses including PO Boxes, Apartments and Suites
- Customize selections by City, Province, State, Postal Code or any shape-based search
- Latitude-longitude coordinates including available census data and address type (residence or business)
- Monthly updates with adds, deletions and changes

The “Key” Makes GAD 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 GAD, 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. MAKs optimize updates from the USPS address database and other postal authorities to ensure your address file is accurate.
How to Use GAD
GAD is a boon to the first responder community – imagine a complete 911 address database with up-to-date residential and business addresses easily accessible to fire departments or 911 emergency call centers. The ability to quickly identify an address can help ensure first responders reach the correct location immediately.
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.
Additional uses of GAD include optimizing route planning and resource allocation, enriching data for analytics, utilities management (water/gas/waste), and risk assessment.
