Correct Lastline

When Output corrected last line is enabled, the elements of the output lastline are corrected, providing a good ZIP Code or close match on the soundex even if the address did not match or was non-existent. This feature is disabled by default.

When Correct Lastline is enabled, the following elements are corrected:

• City correction - The city correction is based on input ZIP Code unless a match to city and state exists in which case both search areas are retained. The input state must be correct or spelled out correctly when no ZIP Code is input. The returned location code and coordinates are based on the output ZIP Code.
  • Input city is incorrect:

    HAUDENVILLE MA 01039
    Returns LASTLINE=HAYDENVILLE, MA 01039 LAT= 42396500 LON= -72689100

• State correction - State is abbreviated when spelled out correctly or corrected when a ZIP Code is present. There are some variations of the input state which are recognized, ILL, ILLI, CAL, but not MASS. The US geocoder does not consider the abbreviation of the variation a change, so ILL to IL is not identified as a change in the match code. In addition, the output of the ZIP Code for a single ZIP Code city is not considered a change.
  • Input city exists:

    Bronx NT, 10451
    Returns LASTLINE= BRONX, NY 10451

    Bronx NT
    Returns LASTLINE= BRONX NT
    No ZIP Code for correction.

  • Input city does not exist - preferred city for ZIP Code returned:

    60515
    Returns LASTLINE=DOWNERS GROVE, IL 60515
    MATCH_CODE=E622

    ILLINOIS 60515 (or ILL 60515 or IL 60515 or ILLI 60515)
    Returns LASTLINE=DOWNERS GROVE, IL 60515
    MATCH_CODE=E222

• ZIP Code correction - The ZIP Code is corrected only when a valid city/state is identified and has only one ZIP Code.
  • Exists on input:

    HAUDENVILLE MA 01039
    Returns LASTLINE=HAYDENVILLE, MA  01039

  • Incorrect on input - ZIP Code correction is not performed, both search areas are retained:

    HAUDENVILLE MA 01030
