Read the first 7 Address Hygiene & Data Quality flashcards as text

  1. When processing a mailing list with NCOALink, what does a Type 2 move indicate?

    Answer: An individual at an address moved, but other residents remain

    NCOALink Type 2 move codes indicate that an individual moved but other members of the household did not.

  2. What is the maximum lookback period for move data maintained in the NCOALink database?

    Answer: 48 months

    NCOALink maintains change-of-address data for up to 48 months (4 years) from the date of the move.

  3. An address record fails DPV confirmation but passes ZIP+4 coding. What is the most likely reason?

    Answer: The specific primary number does not exist in the USPS delivery point database

    DPV confirms at the individual delivery point level; a ZIP+4 match without DPV confirmation often means the specific house number isn't in the DPV file.

  4. Which CASS output field indicates that an address was matched to a USPS record but required significant changes to achieve the match?

    Answer: Error code or footnote indicating a modified record

    CASS software uses error codes or footnotes to signal when a match required significant corrections to the input address.

  5. What is 'SuiteLink' used for in address hygiene processing?

    Answer: Appending secondary address information to business addresses

    SuiteLink appends suite or unit numbers to business addresses that are missing secondary address information.

  6. A carrier route code beginning with 'R' identifies which type of route?

    Answer: Rural route

    In USPS carrier route codes, the letter 'R' denotes a rural delivery route.

  7. During CASS processing, which step must be completed before DPV validation can be performed?

    Answer: ZIP+4 coding

    DPV validation requires a valid ZIP+4 code to look up the specific delivery point, so ZIP+4 coding must occur first.
