DPV™ (DELIVERY POINT VALIDATION)

PER/ZIP4 Includes PER/DPV, a DPV Interface

In August of 2007 the United States Postal Service began requiring that all CASS Certified™ postal coding solutions perform DPV (Delivery Point Validation) as part of CASS processing. PER/DPV is the module that adds DPV functionality to PER/ZIP4.  PER/DPV is automatically installed with PER/ZIP4 and cannot be bypassed or disabled.

DPV allows PER/ZIP4 to indicate whether or not an exact address is a valid delivery point for the USPS. Prior to the introduction of DPV, PER/ZIP4 could only determine that an address matched to an address range present in the USPS National Zip+4 database. DPV allows PER/ZIP4 to provide the highest level of address validation available.

The US Postal Service has estimated that an additional 5 to 8% improvement in delivery quality is achieved by including DPV as a required component of CASS processing. In addition to the basic “yes” or “no” match indicator, DPV provides additional information about the quality of the match, such as whether an apartment or suite number is missing.

DPV allows PER/ZIP4 to provide the following information for addresses processed:

DPV confirmation indicator

  • Y - Address was DPV confirmed for both primary and, if present, secondary numbers
  • D - Address was DPV confirmed for the primary number only, and secondary number information was missing
  • S - Address was DPV confirmed for the primary number only, and secondary number information was present but unconfirmed
  • N - Both primary and, if present, secondary number information failed to DPV confirm

DPV CMRA indicator (CMRA = commercial mail receiving agent)

  • Y - Address was found in the CMRA table
  • N - Address was not found in CMRA table

DPV footnotes

  • AA - Input address matched to the ZIP+4 file
  • A1 - Input address not matched to the ZIP+4 file
  • BB - Input address matched to DPV (all components)
  • CC - Input address primary number matched to DPV but secondary number not matched (present but invalid)
  • N1 - Input address primary number matched to DPV, but highrise address missing secondary number
  • M1 - Input address primary number missing
  • M3 - Input address primary number invalid
  • P1 - Input address missing PO, RR, or HC box number
  • P3 - Input address PO, RR, or HC box number invalid
  • RR - Input address matched to CMRA and PMB designator present (PMB 123 or # 123)
  • R1 - Input address matched to CMRA but PMB designator not present (PMB 123 or # 123)

DPV information is returned by all three PER/ZIP4 interfaces; Interactive, Batch, and Callable Program (API).

Interactive Interface

While using the PER/ZIP4 interactive interface, if an address does not DPV confirm (DPV Confirmation Indicator = N), the message Address could not be DPV confirmed will appear at the bottom of the screen.

Callable Program (API) Interface

While using the PER/ZIP4 callable program interface, if an address does not DPV confirm (DPV Confirmation Indicator = N), the error code “DPV” will appear in the error code (ECOD##) field.

Batch Interface

While using the PER/ZIP4 batch interface, if an address does not DPV confirm (DPV Confirmation Indicator = N), the address will appear on the PER/ZIP4 Coding Report with a “DPV” error code. This error code will appear for each address that does not DPV confirm.

In all cases if an otherwise valid address (i.e. address is within a valid range, valid street name, and valid city/state/zip) is not in the DPV dataset as a known delivery point for mail, the standardized address will be returned by PER/ZIP4 along with a DPV error code/message. When a DPV error code is returned by PER/ZIP4, no +4 or delivery point code is assigned to the address.
