About us
What is Pro6PP?
Pro6PP provides geographic information via an API (web service) and downloadable databases for offline use. For the Netherlands and neighboring countries. We are often used in web shops for address validation, finding a store near you or for calculating travel time and distance between addresses that transport companies find useful.
What is the motivation behind Pro6PP?
In 2008, 6PP was created as an open-source project. The number of users, including many companies, grew rapidly. With Pro6PP, d-centralize meets the demand for support and improvement of the 6PP database.
Our Vision
Primary: Become the global reference for accessible, reliable geodata, empowering precise decision-making across sectors and regions.
Secondary: Sustainable revenue from Pro6PP supports d-centralize’s mission to incubate public-interest digital infrastructure and open innovation.
Our Proposition
We provide comprehensive, high-resolution geodata per country, engineered for maximum precision and coverage. Our mission is to make this high-quality data easily accessible and affordable.
