The District of Columbia government uses the Master Address Repository (MAR) to implement intelligent search functionality for finding and verifying addresses, place names, blocks and intersections. It provides complete standardization of addressing components so that agency applications and systems maintain clean integration. Most often the MAR is solely known for its address points. The MAR goes beyond DC government and is available for public use in applications with web services and geocoding tools.
- Addressing in DC - including datasets, documentation, tools and FAQ
- Data Developer Portal - including MAR 2 API and developer guides
- MAR Web Geocoder - for one-off geocoding of spreadsheet datasets
- DC Location Viewer - for one-off addresses searches to identify location and common DC geographic boundaries
