ReverseAPNLookup

Information to perform Reverse APN Lookup using Assessor's Parcel Number (APN), A FIPS county code, A FIPS state code.

ReverseAPNLookup allows you to look up an address using:

An Assessor's Parcel Number (APN). An APN is an ID number assigned to a piece of land by a county assessor. An APN is unique only within a county.
A FIPS county code. A Federal Information Processing Standard (FIPS) code is an ID number assigned to a county by the U.S. Federal government.
A FIPS state code. A FIPS state code is an ID number assigned to each state by the U.S. Federal government.

These three pieces of information, used together, can uniquely identify a specific parcel. You must use all three pieces of information to perform a lookup using ReverseAPNLookup.

Note: ReverseAPNLookup only works for U.S. addresses for which APN data is available, such as Centrus Enhanced or Centrus Premium Points. See the coverage map included with the points database for more information.

ReverseAPNLookup is part of Enterprise Geocoding. For more information, see Enterprise Geocoding.
