CASS Postal Address Verification & Validation 3 — Questions and Answers
Question 1: What is the purpose of the LACSLink process within CASS-certified software?
- Convert PO Box addresses to street addresses
- Update rural route addresses to city-style street addresses (Correct answer)
- Assign carrier routes to business reply mail
- Verify ZIP+4 codes for military addresses
Correct answer: Update rural route addresses to city-style street addresses
LACSLink converts rural route and highway contract route addresses to the new city-style (911) street address format assigned by local governments.
Question 2: Which CASS output field provides a two-character code explaining why an address did or did not receive a full match?
- DPV Return Code
- DPV Footnote Codes (Correct answer)
- Record Type Indicator
- Carrier Route ID
Correct answer: DPV Footnote Codes
DPV Footnote Codes (up to two characters) explain the specific reason an address received its DPV Return Code, such as missing secondary or input match.
Question 3: When standardizing a directional in an address such as '123 N Main St', what does USPS Publication 28 call the element 'N'?
- Predirectional (Correct answer)
- Postdirectional
- Secondary address designator
- Suffix abbreviation
Correct answer: Predirectional
A directional that precedes the street name is called a predirectional; one that follows the street name is a postdirectional.
Question 4: What is the function of SuiteLink in CASS processing?
- Add suite numbers to high-rise business addresses using firm name data (Correct answer)
- Validate PO Box suite assignments
- Link LACSLink records to updated carrier routes
- Assign ZIP+4 to military APO/FPO addresses
Correct answer: Add suite numbers to high-rise business addresses using firm name data
SuiteLink appends secondary information (suite numbers) to high-rise business addresses by matching the company name against a USPS database.
Question 5: A CASS Form 3553 must be completed by which party?
- The USPS Business Mail Entry Unit
- The presort bureau or mailer who processed the list (Correct answer)
- The software vendor that provided the CASS engine
- The local postmaster of the mailing facility
Correct answer: The presort bureau or mailer who processed the list
The presort bureau or mailer who actually ran the list through CASS-certified software is responsible for completing and signing Form 3553.
Question 6: Which element of an address is verified last in the CASS match hierarchy?
- ZIP Code
- City and state
- Primary address number
- ZIP+4 add-on (Correct answer)
Correct answer: ZIP+4 add-on
CASS matching proceeds from city/state, to ZIP, to street name, to primary number, and finally assigns the ZIP+4 add-on as the last step.
Question 7: Under CASS, what is the correct action when an input address contains a secondary designator (e.g., 'APT') but no secondary number?
- Accept the address as fully matched
- Flag it with DPV footnote 'CC' for missing secondary number (Correct answer)
- Reject the address entirely from the mailing list
- Default the secondary number to '1'
Correct answer: Flag it with DPV footnote 'CC' for missing secondary number
When a secondary designator is present but the unit number is missing, CASS software assigns DPV footnote 'CC' to indicate the secondary information is incomplete.
