Geographic Append Service

Empower Location Intelligence with Rooftop Geocoding

Append precise rooftop latitude and longitude information to the U.S. and international street addresses that you have gathered in your mailing list, website, or other business contact-dependent process. Use these geo-coordinates with a mapping program to determine the distance between any two sites, pinpoint customer locations, or find the closest dealer to a customer. Use the tract and block numbers to link addresses to demographic information and valuable Census marketing data.


  • Geocode U.S. addresses to the rooftop level to accurately pinpoint customer locations
  • Coverage spans 40+ countries and territories
  • Visualize customer relationships to facilitate market analysis and improve business intelligence

U.S. Geocoding

Melissa Data’s service provides the GeoPoints for 95% of all U.S. delivery addresses (business and residential). GeoPoints are the rooftop (delivery point) latitude and longitude coordinates for an address – the highest level of geocoding granularity available for precise location intelligence.
