DPV stands for Delivery Point Validation, the process that confirms whether a specific address is a real, deliverable USPS delivery point.

- Firm record

Street records represent all delivery addresses within a range on a given street segment, covering both even and odd ranges.
Question 3: A mailer wants to qualify for carrier route presort rates. Which CASS-related process assigns the carrier route code to each address?
- LACSLink
- DPV processing
- ZIP+4 coding with carrier route assignment (Correct answer)
- SuiteLink matching
Correct answer: ZIP+4 coding with carrier route assignment
Carrier route codes (e.g., C001, R002) are assigned during ZIP+4 coding when the CASS software matches an address to the AMS street or PO Box record.
Question 4: What is the minimum number of questions a CASS test deck must contain to evaluate software performance?
- 100
- 500 (Correct answer)
- 1,000
- 2,500
Correct answer: 500
USPS provides a CASS test deck of at least 500 address records that certified software must process to demonstrate accuracy thresholds.
Question 5: When a street address is matched to the USPS database but the input ZIP Code is incorrect, what should CASS-certified software do?
- Reject the address and leave the ZIP unchanged
- Correct the ZIP Code and assign the proper ZIP+4 (Correct answer)
- Flag the record for manual review only
- Assign a default ZIP Code for the city
Correct answer: Correct the ZIP Code and assign the proper ZIP+4
CASS-certified software corrects the ZIP Code based on the matched street address data and assigns the full ZIP+4, overriding the incorrect input.
Question 6: Which CASS certification cycle runs from November 1 through October 31?
- Annual CASS Cycle A

- IA
- R7 (Correct answer)
- M3

Correct answer: R7
DPV footnote 'R7' identifies addresses classified as 'No Statistics,' meaning they are valid delivery points withheld from public DPV confirmation for security purposes.
