FAQ What is "Split List" in the address check results? The Split List option in the Address Check results screen is used to export your lists into one of three new lists. The first are records coded to ZIP+4 level. The second is for records coded to the 5-Digit ZIP level and the last is only records with errors. Use this feature when you want a file with only ZIP+4 coded records, 5-digit ZIP coded records or records with Address Check errors.
