ZP4 Outputs

The ZP4 address correction engine can input an incomplete or ambiguous address, match it to the ZIP + 4®, DPV®, LACSLink®, SuiteLink™, RDI™, eLOT®, and Geo databases, and generate the outputs listed below. ZP4's documentation explains these outputs in more detail. Various tools included with ZP4 allow you to manipulate these outputs in a variety of ways (such as automatically updating every record in a file). You can also export raw data directly from the ZIP + 4 database.

Address (final): the recommended, standardized form of the input address as used by ZP4 to try and find a match in the ZIP + 4 database. If the input address is "SUITE A 123 MAIN STREET", then Address (final) would be "123 MAIN ST APT A".

Address (delimited): the same as Address (final), except vertical bars delimit the seven subfields that form the standardized address. If the input address is "SUITE A 123 MAIN STREET", then Address (delimited) would be "123||MAIN|ST||APT|A".

Address (long): the longer unabbreviated form of the address when Address (final) is required to be 30 characters or less.

Address (parsed): the same as Address (delimited), except tab characters are used instead of vertical bars.

Address leftovers: any words from the original input address that were not used in Address (final). If the original address is "100 MAIN ST PAYABLES" then Address (final) would be "100 MAIN ST" and Address leftovers would be "PAYABLES".

Address line 2 (final): private mailbox information (such as "PMB 123") if the input address used a PMB designation and the input address occupied two lines.
