LICENSE AGREEMENTCHANGES

• 1.2 The term “address attributes” shall refer to the data elements derived through the use of the individual tables supplied by USPS to Licensee to perform DSF2 processing. Address attributes are specifically considered to include: a. Seasonal indicator b. Vacant indicator c. Delivery mode type indicator d. Residential indicator (reference Figure 4 in the Licensee Performance Requirements) e. Business indicator f. Drop indicator g. Drop count h. Locatable Address Conversion System (LACS) indicator I. No-stat(istics) indicator j. Address throwback indicator

LICENSE AGREEMENTCHANGES

19.0 Compliance With Coding Accuracy Support System (CASS) Certifications And Periodic Verification Of DSF2 Matching Capability

19.1 Licensee shall maintain current Coding Accuracy Support System (CASS) certification for ZIP+4 Coding and Delivery Point Coding. To meet this requirement Licensee must be re-certified at each CASS cycle or as specified by USPS.

19.2 This required test shall be performed in conjunction with the CASS certification. In addition to the CASS certification, USPS shall have the right to test the accuracy of the DSF2 process at any time without advance notice.

19.3 Failure to meet the standards established by the CASS certification process or for DSF2 processing as defined within the Licensee Performance Requirements may result in suspension or termination of this License.

{4.9} 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: [email protected]

6



“NO STATS”

4.11 “No Stat” addresses: The Licensee shall capture those addresses with a “No Stat” flag that do not result from a default-level match and submit them to the USPS for review. License shall compile and forward monthly to the USPS the file that contains the “No Stat” values. See record layout for the 9-digit ZIP+4 Code and the associated primary and secondary address values that produced the “No Stat” value. The report should only be sent for highrise exact records that have a “No Stat” flag (see example #1 and #2) and confirmed S records that are flagged as “No Stat” and have no associated highrise records at the same primary address (see example #3 and #4).

7

Example #1

Input = 102 Main St Apt B

DSF2 reports 102 Main St Apt B is a “No Stat” record

38119-1236 has DPV confirmed

Since the address is not a default record, it should be reported.

CERTIFICATIONCHANGES

Delivery Point Validation Product (DPV)

The United States Postal Service (USPS) has developed a new technology product that will help mailers validate the accuracy of their address information, right down to the physical delivery point. Mailers will be able to identify individual addresses within a mailing list that are potentially undeliverable-as-addressed due to an addressing deficiency.

14



Second Generation Delivery Sequence File – Licensed Service (DSF2). The USPS has transitioned from the use of the Delivery Sequence File (DSF) data to the new DSF2 Product. Where DSF was licensed to a network of commercial firms (DSF Licensees) that provided address list processing services for the mailing community, the USPS has substituted the DSF data with the new DPV Product and additional data sets to fully replicate the DSF services. Through a network of licensed service providers, the mailer can also obtain unique address attributes such as, “Is the delivery address a business location?” or “Is the delivery address currently vacant?” To help distinguish the services available under the original DSF license agreement from the new services based upon the DPV Product, the USPS will refer to the new service as Second Generation Delivery Sequence File – Licensed Service or by its service mark DSF2.

15



DSF2 Licensed Service contains the same data found in the Basic DPV Product along with additional address-attribute data. Address-attribute data are additional intelligence flags not directly related to the address format or content: instead they tell the mailer something more about an address. An example of address-attribute data would be, “Is this address vacant?” or, “Is this address a business delivery address?” or, “Is this address delivered into a curb-side mailbox or a Collection Box Unit (CBU)?” The address-attribute data provides the mailer with knowledge about the address, above and beyond what is necessary to accurately format the address. Address-attribute data allows mailers to produce more targeted mailings. An example might be a mailer who wants to send out a coupon for lawn care services – this mailer may only want to mail to residential addresses that are not centralized, because apartment dwellers do not have lawns.

4) If RAM is a concern, consider using the 100 file split version. (See Title 4, Testing the hash table for SHA'd EMDP using Split Files.)

18



Finally test the secondary number’s first position for a ‘1’ and the second position for a non-digit or non-alpha, and the third position for a ‘2’, and the fourth and subsequent positions are spaces. If this pattern is found, replace the positions containing the ‘1’ and ‘2’ with ‘9’. The purpose of this test is to locate ½ and change it to 9/9.

19



(8) Enhanced Line-of-Travel (eLOT)

The eLOT sample data, file layout, and directions on how to use the eLOT file are located on the web at the following address: http://ribbs.usps.gov/files/eLOT

The process to create the Pseudo Delivery Sequence Numbers require the following steps:

1) The file should first be sorted by eLOT in the following sequence: ZIP Code; Carrier ID, eLOT Sequence, ZIP+4 code and DPC, then ascending or descending based on the flag in the eLOT Master file.

If your input data element was not located, the software will assign a default of “0000D”. Please refer to DMM M050 1.2 for sorting in this case.

20



Continued (8)

2) At the beginning of each ZIP Code and Carrier Route, begin re-sequencing with Pseudo Delivery Sequence Number of ‘0001’. For each additional delivery point within the ZIP Code and Carrier Route, increment the Pseudo Delivery Sequence Number by one until you get to the end of that Carrier Route ID. At the beginning of the next ZIP Code or Carrier Route, begin re-sequencing with the Pseudo Delivery Sequence Number of ‘0001’. Perform this process until you have reached the end of the customer file.

3) Remove the eLOT Delivery Sequence Number and the Ascending/Descending Code from the customer’s final file.

**** No Delivery Type on Match –

If you get a DPV confirm (BB) or (CC) Input Address Matched toDPV (all components) and no delivery type, you need to move (N1)Input Address Primary Number Matched to DPV but HighriseAddress Missing Secondary Number to the footnote code, replacing BBor CC with N1.

DPV validates the address when there is a Highrise record missingfrom the database. If there are only records with secondary informationand no Highrise default, DPV will make a Highrise default record with nodelivery type and validate that record.
