Read the first 6 CASS Deliverability & Return Mail Management flashcards as text

  1. What does the USPS Mailer Scorecard track related to undeliverable mail?

    Answer: UAA rates and Move Update compliance across mailings

    The USPS Mailer Scorecard tracks UAA rates and Move Update compliance metrics to help mailers monitor and improve list quality.

  2. Which address correction method provides the fastest and most cost-effective way to update large mailing lists before a drop?

    Answer: NCOA processing

    NCOA (National Change of Address) processing batch-updates entire lists against USPS move data before mailing, preventing UAA mail proactively.

  3. If a mail piece is marked UNDELIVERABLE and returned with no forwarding address, what should the mailer do with that record?

    Answer: Suppress or flag the record for review and update

    Returned UAA records should be suppressed or flagged for research and correction to prevent future waste and maintain list hygiene.

  4. What CASS output field indicates whether a delivery point is currently active and receiving mail?

    Answer: DPV Confirmation Indicator

    The DPV (Delivery Point Validation) Confirmation Indicator confirms whether an address is a real, active USPS delivery point.

  5. Which USPS service allows mailers to receive electronic address correction data instead of physical nixie mail?

    Answer: OneCode ACS

    OneCode ACS (Address Change Service) uses Intelligent Mail Barcodes to deliver electronic address correction notifications to mailers.

  6. A mailer processing CASS finds that 8% of records receive a DPV 'S' (secondary number missing) result. What does this mean for deliverability?

    Answer: A secondary number (apt/suite) is needed for reliable delivery

    DPV result 'S' means the primary address is valid but a required secondary number (apartment, suite, unit) is missing, risking delivery failure.
