Matching to Auxiliary Files

Geocode US Address matches an input address to an auxiliary file as follows:

  1. Geocode US Address determines if there is an auxiliary file present.

    If you have an auxiliary file in the dataset directory, Geocode US Address automatically loads and attempts to match to the auxiliary file. You can verify that Geocode US Address found an auxiliary file by looking at the version information page in the Management Console. One of the following statuses display:

    • Loaded—An auxiliary file is loaded
    • None—An auxiliary file has not been found or loaded
    • Invalid—An auxiliary file was found, but failed to successfully load

    Geocode US Address only accepts one auxiliary file. If more than one auxiliary files is present, Geocode US Address attempts to match against the first file. Geocode US Address ignores any additional auxiliary files for matching, regardless if Geocode US Address found a match to the first auxiliary file.

    If a record in the auxiliary files is invalid, Geocode US Address returns a invalid record message. Geocode US Address continues to match input addresses with the auxiliary file, but will not match to the invalid auxiliary file record.

  2. If an auxiliary file is present, Geocode US Address attempts to match to the auxiliary file.

    Geocode US Address assumes that the auxiliary file is the most accurate data set and attempts to find a match to the input address in the auxiliary file. If Geocode US Address cannot find a match in the auxiliary file, it matches the input address with the other Enterprise Geocoding databases.

    Note: Geocode US Address only matches input address lists to auxiliary files if there is an exact match. Your input address list should be free of misspellings and incomplete addresses.
  3. If Geocode US Address finds an exact record match to the auxiliary file, it standardizes the match to USPS regulations and returns the output of the auxiliary file match.

    Geocode US Address uses the following defaults if you do not include the values in the auxiliary file:

    • House number parity = B (both odds and evens)
    • Segment direction = A (ascending)
    • Side of street = U (unknown)
