Master Location Data (MLD) provides the best available address point location for every mailable and deliverable address in the United States.
There are additional optional datasets used in conjunction with MLD to provide extended feature support:
- The Master Location Reverse PreciselyID Dataset (MLDR) is an optional licensed dataset that supports the Reverse PreciselyID Lookup feature.
- The Master Location Structure Centroid Dataset (MLDB) is an optional licensed dataset that provides additional match returns to building centroids, as well as support for an Expanded Centroids feature.
Your license file determines the data you can access. The following table describes the files you receive by product.
