| Database | Required or
Recommended for CASS Processing | Description |
|---|---|---|
| CITYFILE | Required | Provides basic address matching. |
| DATAFILE | Required | Provides ZIP + 4 address matching. |
| EWSFILE | Recommended | The Early Warning System (EWS)
database provides early alerts to address changes that could impact your
address file. For example, your input file contains the address 123 MAIN ST.
The ZIP4 DATABASE only contains MAIN RD. Since MAIN RD is the only entry in the
ZIP + 4 database, without EWS processing, the input address would be changed to
MAIN RD. Finalist can read the EWS database to determine that a new address
MAIN ST has been created. Finalist does not change the input address to MAIN RD
ensuring that mail is not delivered to the wrong location.
Each monthly database ships with a copy of the EWSFILE database. However, you are encouraged to obtain the most current information available from the USPS website. Visit https://postalpro.usps.com/ and look for file EWS002C0.ZIP. |
| LOTFILE | Recommended | The Enhanced Line Of Travel or eLOT database provides routing information for your coded addresses. While eLOT processing is not required for CASS certification, it is required to obtain discounts. To accomplish this, perform eLOT processing as part of your address hygiene processing or separately as part of your presort processing. |
| DPVxDB | Required | The Delivery Point Validation (DPV)
database provides point specific information about addresses. The ZIP4
databases match addresses to a range. For example, for the address "100-200 N
MAIN ST.", DPV further qualifies the address to identify 101 as a valid
delivery point where 103 is not.
DPV has three (3) formats of its data:
|
| LLKDB | Required | The LACSLink database provides address conversion.
For example, the old style address "RR 1 BOX 123" should be
converted to "604 S 450 W" for a more accurate delivery of the mailpiece. This
is often referred to as the E911 database since it allows emergency personnel
to more accurately identify the address location.
USPS CASS regulations require LACSLink processing for CASS certification. If you do not perform LACSLink processing, Finalist does not generate a USPS Form 3553 (CASS Summary Report). |
| PRCSLYDB | Optional |
For each addressable location, PreciselyID processing provides a unique and persistent identifier to reference the address without storing the whole address string. The PreciselyID is further verification an address exists, regardless of DPV matching. Additionally, to link it to other data (i.e., geoenrichment), Precisely has done the complex matching for you. Use the PreciselyID as the gateway to the rest of the Precisely data portfolio. Contact your Sales Representative for more information, based on your specfic needs. |
| RDIDB | Recommended | The Residential Delivery Indicator (RDI) Option is designed to identify if an address is a residential (RDI=Y) or a business (RDI not equal to Y) address. |
| SLKDB | Required | The SuiteLink database provides more
accurate matching for firms and businesses. For example, WIDGET COMPANY; 2200
WESTERN CT; LISLE IL 60532 is missing the unit (suite) information to
accurately deliver the mail. SuiteLink provides the ability to look into the
address file and determine that firm WIDGET COMPANY really belongs at a
secondary range of STE 100. USPS CASS regulations require SuiteLink processing for CASS certification. If you do not perform SuiteLink processing, Finalist does not generate a USPS Form 3553 (CASS Summary Report). |
