## DPV/DSF2 CERTIFICATION

## DSF2/DPV CERTIFICATIONI

_**Annual Certification**_
**Will coincide with CASS requirements. **
**If changes are made for new CASS requirements and CASS requires an Annual certification, you must also certify for DPV/DSF****2****. If CASS does not require an annual certification, you will not be required to certify for DPV/DSF****2****. **
**Ex: If only changes to the 3553 are required and CASS does not require the annual certification, then you are not required to certify DPV/DSF****2****.**

## DSF2/DPV CERTIFICATION

_**CASS Certification with **_
_**Test Data vs. Live Data**_
**Stop processing must only be demonstrated  during the initial CASS test.**
**Once the customer is certified and begins to use live data, the stop processing function will not have to be demonstrated during re-certification.**

## DSF2/DPV CERTIFICATION

_**Footnotes**_
**We have added this footnote:**
**	**_**P3**_** – Input address PO, RR, HC Box number invalid**
**We will be grading this footnote in the CASS test during the next cycle:**
**	**_**R1**_** -  Input Address Matched to CMRA but PMB designator not present (PMB 123 or #123)**

## DSF2/DPV CERTIFICATION

_**DPV Stop Processing for CASS Testing**_
**If you hit a false positive record, you must send the information described below to:**
**	**_**[Dsf2stop@email.usps.gov](mailto:Dsf2stop@email.usps.gov)**__** **_
**	****The subject of the email should be **_**CASS Test**_**.**
**We will take the record and compare it to the record that was sent in your CASS Stage file. If it is truly a false positive record, we will notify CASS you have passed the stop processing side of your test. If it does not match, we will notify CASS you have failed the stop processing side of your test. **

## DSF2/DPV CERTIFICATION

**Per Paragraph 4.1 in the License Agreement, The DPV Product shall not be used to facilitate creation of address lists artificially.  To detect conditions when address records appear to be the result of artificial manufacture and not legitimately obtained addresses, a “seed” table of artificially manufactured addresses is provided as part of the DPV Product.  These seed addresses reside in the False Positive table.  For each negative response that occurs in a query of the DPV Product hash table (Table A), a query must be made to the False Positive table (Table F). The Licensee shall design a “stop DPV processing” function that will cause their interface to cease delivery point validating addresses when the interface encounters a list containing an apparent artificial address (the process can continue ZIP+4 encoding).  Any time an address encounters a hit in the False (hsf) table, the DPV validation function shall be halted immediately. The Licensee must transfer a file containing the affected addresses from each address list to the following address:**

## DSF2/DPV CERTIFICATION

**Per Paragraph 13.3 in the License Agreement, DSF2 shall not be used to facilitate the artificial creation of address lists. To detect conditions when address records appear to be the result of artificial manufacture and not legitimately obtained addresses, a “seed” table of artificially manufactured addresses is provided as part of the DPV System. These seed addresses reside in the False Positive table. For each negative response that occurs in a query of the DPV hash table (Table A), a query must be made to the False Positive table. Anytime an address encounters a hit in the False (hsf) table, the Licensee should continue processing, but must notify the USPS of the customer’s name and address (using the file layout below) and shall withhold update to the customer until approval from the USPS is provided. The Licensee must transfer a file containing the affected addresses from each address list to the following address:**

_**Pseudo Sequencing On CASS Test**_
**A separate pseudo sequencing test will be incorporated into the Stage 2 CASS test for next year’s cycle.**
**100% will be required on this test.**
**The file layout will be the same as the CASS Stage 2 layout, but will have an additional field for the pseudo sequence number.**
**The new layout will appear in the CASS minutes.**
