Reverse PBKey Lookup

Reverse PBKey Lookup allows you to look up an address using a pbKeyTM unique identifier as input and returns all standard returns that are provided as part of address matching. For information about the use cases for Reverse PBKey Lookup, see Use Cases.

Licensing

Reverse PBKey Lookup requires a special license. There are two levels of licensing for Reverse PBKey Lookup:
  • Standard - This license allows Reverse PBKey Lookup of all of the standard MLD addresses.
  • Enhanced - This license allows Reverse PBKey Lookup of a portion of MLD addresses that require an additional royalty due to address sourcing constraints.

Requirements

Reverse PBKey Lookup includes these requirements:
  • You have licensed, installed and added as a database resource the Master Location Dataset (DVDMLD and DVDMLD2).
  • You have licensed, installed and added as a database resource the DVDMLDR dataset.
  • The MLD and DVDMLDR datasets must be the same vintage.

Reverse PBKey Lookup Search Results

When using Reverse PBKey Lookup, the search results can return zero to many MLD point address variations that match the input PBKey. There will be no matches returned if the given PBKey is not found. While many PBKeys map to a single point-level address, some PBKeys map to multiple point address variations. Getting multiple point address variations from one PBKey can occur in two circumstances:
  1. Alias matches. Some streets are known by their common name and one to many aliases. In this case, MLD may contain all variations of street names. An example of multiple alias match returns for an input PBKey (P00008BCG8WM) is shown below:
    • AP02. Normal match (non-alias). 1206 W 600 S, FOUNTAINTOWN, IN 46130-9409
      Note: For the alias match results below, the alias addresses are represented; however, the address returned is the normal match address: 1206 W 600 S. The value returned in the isAlias field will indicate an alias match result.
    • AP02. Alias match. 1206 W 1200 N, FOUNTAINTOWN, IN 46130-9409
    • AP02. Alias match. 1206 W COUNTY ROAD 1200 N, FOUNTAINTOWN, IN 46130-9409
    • AP02. Alias match. 1206 W COUNTY ROAD 600 S, FOUNTAINTOWN, IN 46130-9409
  2. Multi-unit buildings with/without units. In some cases, there are multi-unit addresses without individual unit address records. In this case, you may see multiple address records returned for the same input PBKey, some without unit designations and others with ranged unit designations. In the case of multi-unit addresses that have individual suite/unit number address designations, each will have their own distinct PBKey. The following example shows address results for a PBKey that maps to a building with and without units, which share the same PBKey/location (P00003PZZOIE):
    • AP02. Normal match (non-alias). 4750 WALNUT ST, BOULDER, CO 80301-2532
    • AP02. Normal match (non-alias). 4750 WALNUT ST STE 100-103, BOULDER, CO 80301-2532
    • AP02. Normal match (non-alias). 4750 WALNUT ST STE 205-205, BOULDER, CO 80301-2532
    • AP02. Normal match (non-alias). 4750 WALNUT ST, BOULDER, CO 80301-2538
