What is DPV?

DPV indicates if an address is complete and correct. Adding in DPV information further enhances the accuracy of the database. Going beyond the capabilities of CASS, which simply assigns ZIP + 4 codes based on address block range data, DPV will detect incomplete addresses such as missing apartment numbers and will flag the address as being deliverable or not, based on U.S. Postal Service® information.  more

DPV stands for Delivery Point Validation and basically validates that there is an actual mailbox at a particular street number and/or apartment number. That is, if an address passes DPV, then mail can be delivered there.  more

DPV (Delivery Point Validation) is a USPS service that allows CASS-certified software to confirm if an address is valid delivery point. That is, if it is a good address in the USPS database, to which the USPS could deliver mail. What's the big deal about DPV? Under the Cycle L rules, only those addresses that have confirmable primary number information (street number, Post Office Box number, or, in some cases, rural route box number) will be assigned the proper ZIP + 4. If DPV cannot confirm the PO box or primary number/street combination along with the ZIP code as an actual address, the CASS software will not output a ZIP + 4 for that address What if the ZIP + 4 code isn't on the address? No ZIP + 4 means that the address cannot qualify for automation discounts. Also, if DPV can't confirm the address, it's possible that the USPS might not be able to deliver mail to the address. What is that missing ZIP + 4 costing me? We have heard that our customers are paying 5 cents to 15 cents ...  more

Delivery Point Verification (DPV) is an add-on feature of MAILERS+4 that comes on a separate CD-ROM. DPV is an option found in Address Check function. When it is enabled your list will be verified to a higher standard. Where the CASS Certification of Address Check verifies that an address is in a valid range, DPV verifies that an actual address is valid. For example, all the addresses in the range of 120 to 130 Main St will have the same ZIP+4. The DPV add-on will indicate which of the addresses in the range of 120 to 130 are valid or invalid and therefore should not be mailed. DPV will improve the accuracy of your mailing list and help you save on postage and printing.  more
