Master Address Repository (MAR)

The MAR is a database of building addresses, blocks, intersections, place names and other location identifiers in the District. The MAR allows the District government to more easily compare and relate information with locations across databases and agencies. Each address in the MAR is standardized and assigned a unique Address Identification Number (AID), map coordinates and other useful information.
