What does CASS processing do?

CASS-certified software evaluates and standardizes addresses against USPS address data. It supports automation-compatible addressing but does not turn every incomplete or incorrect record into a deliverable address.

Is NCOA processing always required?

Requirements depend on the mail class and the Move Update method used. We review the planned mailing and explain which processing and documentation apply.

Can DIS Direct remove duplicates?

Yes, using agreed matching and householding rules. We confirm the logic first because a duplicate for one campaign may be an intentional separate record for another.

Mailing Data Processing

Mailing data processing for cleaner, deliverable lists.

Mailing data processing prepares a recipient file for accurate production and USPS entry. DIS Direct standardizes and validates addresses, applies CASS and NCOA processing when required, removes or flags duplicates by agreed rules, builds presort records, and connects the approved output to personalization, matching, and postal preparation.

A print-ready PDF does not make a list mail-ready. We establish the input format, processing rules, exception handling, and approved output before the file drives variable print or postal documentation.

From raw list to production file

The exact workflow depends on mail class and program rules, but the goal is consistent: create an auditable output that print, personalization, and postal preparation can use without changing records informally on the floor.

Field mapping and file normalization
CASS address standardization and validation
NCOA processing when applicable
Deduplication and suppression using client-approved rules
Presort records, barcodes, and production outputs

Rules agreed before records are changed

Duplicate logic, householding, suppression, invalid-address handling, and output fields can materially change a mailing. We document those decisions with the program owner instead of guessing at intent.

Data connected to VDP and postal preparation

Keeping data processing beside variable print, matched inserting, and presort reduces version drift. The approved recipient file stays tied to the proof, production count, and USPS entry plan.
