CASS DPV & ZIP+4 Processing 2 — Questions and Answers
Question 1: What does a DPV confirmation indicator of 'Y' signify?
- Both the primary and secondary address numbers are confirmed as valid delivery points (Correct answer)
- Only the ZIP+4 code has been successfully validated
- The address is confirmed as a residential-only delivery point
- The primary number is valid but the secondary number is unconfirmed
Correct answer: Both the primary and secondary address numbers are confirmed as valid delivery points
A DPV confirmation indicator of 'Y' means the address is fully confirmed—both primary and secondary numbers match a deliverable point in the USPS database.
Question 2: Which DPV footnote code indicates that an input address was matched to a CMRA (Commercial Mail Receiving Agency)?
- N1
- R1 (Correct answer)
- S1
- P1
Correct answer: R1
Footnote R1 is returned when the address matches a CMRA, such as a UPS Store or postal annex that accepts mail on behalf of customers.
Question 3: Which ZIP+4 footnote is returned when an address matches only at the 5-digit ZIP Code level and no ZIP+4 code can be assigned?
- AA
- BB
- A1 (Correct answer)
- U1
Correct answer: A1
Footnote A1 indicates the software matched the address to the 5-digit ZIP Code but could not refine the match to a ZIP+4 record.
Question 4: The DPV footnote 'N1' is returned when which condition is detected in the input address?
- The address matched a no-stat delivery point
- The primary address number is missing
- The secondary number (such as an apartment or suite) is missing (Correct answer)
- The address is located in a new development area
Correct answer: The secondary number (such as an apartment or suite) is missing
Footnote N1 indicates the address lacks a required secondary number; the primary number matched but the unit or suite information was absent from the input.
Question 5: What does DPV confirmation indicator 'S' mean in CASS processing?
- The address is in a special seasonal delivery zone
- The primary number is confirmed but the secondary number is missing or not confirmed (Correct answer)
- The address was validated exclusively through the SuiteLink database
- The address matches a shared delivery point
Correct answer: The primary number is confirmed but the secondary number is missing or not confirmed
Indicator 'S' means the primary number (e.g., street number) was found in the DPV database, but the secondary number (e.g., apartment) could not be confirmed.
Question 6: In ZIP+4 processing, what does footnote 'U1' signify?
- The address matched a USPS Unique ZIP Code record assigned to a single organization (Correct answer)
- The address is undeliverable and has been flagged for removal
- The unit number was confirmed through SuiteLink
- The address was updated via a LACSLink conversion
Correct answer: The address matched a USPS Unique ZIP Code record assigned to a single organization
Footnote U1 is returned when the address matches a Unique ZIP Code—a ZIP Code assigned exclusively to a single high-volume mail recipient such as a large company or government agency.
Question 7: Which DPV confirmation indicator is returned when neither the primary number nor secondary number can be confirmed against USPS delivery point records?
- S
- D
- N (Correct answer)
- U
Correct answer: N
A DPV confirmation indicator of 'N' means the address did not match any delivery point in the USPS DPV database for the given primary number.
