CASS Address Hygiene & Data Quality 4 — Questions and Answers
Question 1: When processing a mailing list with NCOALink, what does a Type 2 move indicate?
- An individual at an address moved, but other residents remain (Correct answer)
- An entire family at an address moved
- A business relocated
- The address was flagged as vacant
Correct 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.
Question 2: What is the maximum lookback period for move data maintained in the NCOALink database?
- 48 months (Correct answer)
- 12 months
- 18 months
- 36 months
Correct answer: 48 months
NCOALink maintains change-of-address data for up to 48 months (4 years) from the date of the move.
Question 3: An address record fails DPV confirmation but passes ZIP+4 coding. What is the most likely reason?
- The specific primary number does not exist in the USPS delivery point database (Correct answer)
- The ZIP Code is incorrect
- The state abbreviation is wrong
- The street name is misspelled
Correct 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.
Question 4: Which CASS output field indicates that an address was matched to a USPS record but required significant changes to achieve the match?
- Error code or footnote indicating a modified record (Correct answer)
- DPV confirmation code 'Y'
- ZIP+4 code unchanged
- Carrier route code CR
Correct 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.
Question 5: What is 'SuiteLink' used for in address hygiene processing?
- Appending secondary address information to business addresses (Correct answer)
- Validating rural route addresses
- Converting PO Boxes to street addresses
- Identifying deceased individuals in a mailing list
Correct answer: Appending secondary address information to business addresses
SuiteLink appends suite or unit numbers to business addresses that are missing secondary address information.
Question 6: A carrier route code beginning with 'R' identifies which type of route?
- Rural route (Correct answer)
- City delivery route
- Highway contract route
- Post office box section
Correct answer: Rural route
In USPS carrier route codes, the letter 'R' denotes a rural delivery route.
Question 7: During CASS processing, which step must be completed before DPV validation can be performed?
- ZIP+4 coding (Correct answer)
- NCOALink processing
- Presort sequencing
- Delivery point barcode printing
Correct 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.
