CASS Automation Rate Qualification 2 — Questions and Answers
Question 1: What formula correctly calculates the automation rate for a CASS-processed mailing?
- (Coded addresses / Total addresses) × 100 (Correct answer)
- (Total addresses / Unmatched addresses) × 100
- (ZIP+4 addresses − DPV failures) / 100
- (Automation pieces + Carrier route pieces) / Total pieces
Correct answer: (Coded addresses / Total addresses) × 100
Automation rate is calculated by dividing the number of successfully coded (qualifying) addresses by the total number of addresses, then multiplying by 100.
Question 2: Which USPS form is used to certify and document the results of CASS processing, including match statistics?
- PS Form 3600
- PS Form 3553 (Correct answer)
- PS Form 3602
- PS Form 3865
Correct answer: PS Form 3553
PS Form 3553, the CASS Summary Report, documents the ZIP+4 coding statistics and certifies that CASS-certified software was used.
Question 3: What is the minimum ZIP+4 match rate that CASS-certified software must achieve on USPS test files to maintain its certification?
- 70%
- 80%
- 90% (Correct answer)
- 95%
Correct answer: 90%
CASS-certified software must achieve at least a 90% match rate on standardized USPS test address files to maintain certification status.
Question 4: For First-Class Mail automation letters, within how many days of the mailing date must addresses have been updated via Move Update?
- 30 days
- 60 days
- 95 days (Correct answer)
- 185 days
Correct answer: 95 days
First-Class Mail automation mailings require that addresses be updated through a USPS-approved Move Update method within 95 days prior to the mailing date.
Question 5: When an address fails DPV confirmation during CASS processing, what is the impact on its automation rate status?
- It receives a reduced discount tier
- It cannot be counted toward automation rate and is ineligible for automation discounts (Correct answer)
- It is automatically corrected and re-qualified by the software
- It defaults to carrier route coding instead
Correct answer: It cannot be counted toward automation rate and is ineligible for automation discounts
Addresses that fail Delivery Point Validation (DPV) do not represent confirmed USPS delivery points and therefore cannot qualify for automation postage discounts.
Question 6: Which CASS database is specifically required to convert rural route addresses to city-style street addresses for automation qualification?
- DPV (Delivery Point Validation)
- SuiteLink
- LACSLink (Correct answer)
- RDI (Residential Delivery Indicator)
Correct answer: LACSLink
LACSLink (Locatable Address Conversion System) converts rural route or highway contract route addresses to standardized city-style addresses required for automation processing.
Question 7: What is the correct structure of the 11-digit Delivery Point Barcode (DPBC) used in automation mailings?
- 5-digit ZIP + 4-digit add-on + 2-digit delivery point code (Correct answer)
- 5-digit ZIP + 3-digit carrier route + 3-digit sequence number
- 6-digit state/county code + 5-digit local delivery code
- 4-digit area code + 7-digit address identifier
Correct answer: 5-digit ZIP + 4-digit add-on + 2-digit delivery point code
The 11-digit DPBC combines the 5-digit ZIP code, the 4-digit ZIP+4 add-on, and the 2-digit delivery point code derived from the primary or secondary address number.
