What is Key Lookup?

Key Lookup requires a special license; there are two levels:

• Standard - allows Key Lookup of all of the standard MLD addresses.
• Enhanced - allows Key Lookup of a portion of MLD addresses that require an additional royalty due to address-sourcing constraints.

Key Lookup includes these requirements:

• You have licensed, installed and added as a database resource the Master Location Dataset (MLD).
• You have licensed, installed and added as a database resource the Master Location Dataset for Key Lookup (MLDR) dataset.
• The MLD and MLDR datasets must be the same vintage.

When using Key Lookup, the search results can return zero to many MLD point address variations that match the input PreciselyID. There will be no matches returned if the given Precisely is not found. While many IDs map to a single point-level address, some PreciselyIDs map to multiple point address variations. Getting multiple point address variations from one PreciselyID 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 PreciselyID (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 or 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 PreciselyID, 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 PreciselyID. The following example shows address results for a PreciselyID that maps to a building with and without units, which share the same PreciselyID / 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
