New Contribution API: Submit Address & Geolocation Updates - March 31, 2026
At Melissa, our mission has always been to provide the most accurate and comprehensive address and geolocation data possible. However, even when working with the most premium global data sources, no dataset is ever 100% complete or perfectly up to date. Real-world changes – new construction, address reassignments, and improved geolocation precision – happen constantly. To help bridge this gap and further enhance data quality, we are excited to introduce our new Contribution API. This new capability empowers you to play a direct role in improving the accuracy and coverage of our dataset by submitting address and geolocation updates for review. By combining your real-world insights with our verification processes, we can deliver even more precise and reliable results for everyone. For more details, see the advisory here.
