City-only Lastline Matching

City-only lastline matching permits address matching with only a city in the input lastline. The city should be provided using either the mainAddress (using single-line address input), LastLine or areaName3 input fields.

With city-only lastline input, all of the states are searched in which the input city exists. Therefore, there is the possibility of an increase in multimatches (return of E023 or E030 Match Codes) when matching with city-only input instead of city+state input.

Restrictions:

• City-only lastline input matching is not supported in CASS mode.
• City-only lastline is not supported when matching to User Dictionaries.
• When matching using city-only lastline, the FIND_PREFER_ZIP_OVER_CITY setting is ignored.
• It is strongly recommended to not use city-only lastline matching in Relaxed match mode to avoid the return of false-positive matches.
