Delivery Point Validation (DPV) processing matches the addresses in your address file against the USPS data file to determine whether an address exists and that the USPS actually delivers mail to the address.
For example, your input file contains an address "42 Main Street." CASS processing determines that the address "42 Main Street" falls within the known range "00-99 Main Street" and standardizes the "42 Main Street" address. CASS processing assigns the ZIP Code, ZIP + 4 Code, carrier route code, and delivery point barcode for the known range "00-99 Main Street" to the "42 Main Street" address. However, the "42 Main Street" address belonged to a building that no longer exists. Any mail addressed to "42 Main Street" will be returned to the sender as undeliverable as addressed.
VeriMove solves this problem by using USPS DPV data to determine whether an address actually exists. DPV processing verifies the existence of an address to as fine a level as an apartment or suite. You can use DPV processing to ensure the addresses in your address file are actual physical addresses to which the USPS delivers mail.
USPS CASS regulations require Delivery Point Validation (DPV) processing for CASS certification and to generate the USPS Form 3553 (USPS CASS Summary Report). Although DPV processing is optional for VeriMove job processing, if DPV processing is not enabled for the job, the internal CASS engine will not produce a ZIP + 4 and therefore no forwarding address will be provided by NCOA processing.
Full Service Providers, Limited Service Providers, and End Users are required to use DPV No Stat processing. The USPS requires the No-Stat Table for DPV processing to identify deliveries that are not valid for Computerized Delivery Sequence (CDS) pre-processing. VeriMove counts the occurrences of DPV No Stat flags and reports that statistic on the NCOA monthly reports. If you are a Full Service Provider, Limited Service Provider, or End User, the DPV No Stat option is automatically enabled on the VeriMove UI DPV/LACSLink/SuiteLink tab and cannot be disabled.
Full Service Providers, Limited Service Providers, and End Users are required to use DPV Vacant Table processing. The USPS requires the Vacant Table for DPV processing to identify delivery addresses that have been active in the past but, according to USPS data, have not been occupied within the last 90 days. VeriMove counts the occurrences of DPV Vacant flags and reports that statistic on the NCOA monthly reports. If you are a Full Service Provider, Limited Service Provider, or End User, the DPV Vacant Table option is automatically enabled on the VeriMove GUI DPV/LACSLink/SuiteLink tab and cannot be disabled unless running in DEMO Mode.
The NCOALink Processing Summary Report indicates whether DPV processing was performed. If DPV processing was performed, the report includes processing statistics. For more information, see NCOA/Link Processing Summary Report.
The Qualitative Statistical Summary (QSS) section of the USPS Form 3553 (CASS Summary Report) displays the DPV processing counts. For more information, see USPS Form 3553 (CASS Summary Report).
The VeriMove CASS Postal Coder Summary Report provides details on your DPV database and DPV processing statistics. For more information, see CASS Postal Coder Summary Report.
