if the output contains no DPV-confirmed candidates.
Enhanced ZIP + 4 and DPV Requirement
If you are using DPV mode, and the primary number of the address does not DPV confirm (with Y,
S, or D confirmation code as described in
DPV Column Values on page 147 ), then the USPS ®
requires that MapMarker returns a ZIP Code™ and carrier route only for mailing-related information.
That is, if there is no DPV confirmation, MapMarker will not return the ZIP + 4
®
, Delivery Point,
Check Digit, RecordType, or DefaultFlag.
DPV Data and CASS
MapMarker ships regular data updates to comply with CASS requirements. Because the operation
of DPV is closely tied to the currentness of the CASS data, the ZIP + 4 data is synchronized with
DPV updates to ensure that both are valid for the full 105-day period of the quarter.
If DPV expired on your system, MapMarker still functions normally except that you cannot use DPV
and cannot create a CASS report. However, you can still geocode with CASS rules. To determine
the DPV expiration on your installation, select Help > About from the MapMarker desktop
application.
DPV Output Columns
DPV generates information for each geocoded address during the geocoding process. Your output
table must include several columns to hold this information. These columns contain information
specific to DPV, as well as a number of USPS
®
footnote codes that give more information about how
the address was identified.
