As mentioned in Using correct last line, when set to True, GS_FIND_CORRECT_LASTLINE corrects elements of the output last line, providing a good ZIP Code or close match on the soundex even if the address would not match or was non-existent.
The feature works when GS_FIND_ADDRCODE is True and the address does not match a candidate or when GS_FIND_Z_CODE is True and only last line information is input. The match codes returned are similar to Z and Ennn in that the first letter remains the same with the second digit changing.

| Ehnn | Indicates an error, or no match. This can occur when the address entered does not exist in the database, or the address is badly formed and cannot be parsed correctly. The second digit of the error code is a hex digit which details the changes that were made to the last line information to correct the last line. The last two digits of an error code indicate which parts of an address the application could not match to the database. | |
