CASS Address Matching & Standardization 3 — Questions and Answers
Question 1: What is the purpose of the LACSLink process in CASS certification?
- To validate P.O. Box addresses against USPS data
- To convert rural-style addresses to city-style addresses (Correct answer)
- To verify apartment and suite numbers within a building
- To assign carrier route codes to matched addresses
Correct answer: To convert rural-style addresses to city-style addresses
LACSLink converts older rural route and highway contract route addresses to new city-style address formats required by USPS.
Question 2: A CASS Cycle O database contains what type of address records?
- Only P.O. Boxes and unique ZIP Codes
- Street, P.O. Box, rural route, highway contract, and military addresses (Correct answer)
- Only residential street addresses in urban areas
- Business addresses only with suite-level data
Correct answer: Street, P.O. Box, rural route, highway contract, and military addresses
The CASS Cycle O database (AMS Cycle-O) contains all USPS deliverable address types including streets, P.O. Boxes, rural routes, and military addresses.
Question 3: Which scenario best describes a 'false positive' in address matching?
- An address that exists in USPS data but is flagged as undeliverable
- A non-existent address that matches to a valid USPS record due to similar components (Correct answer)
- A valid address that fails to match due to a minor spelling variation
- A P.O. Box that matches to a street address record
Correct answer: A non-existent address that matches to a valid USPS record due to similar components
A false positive occurs when a non-existent or invalid address incorrectly matches to a valid USPS delivery point due to similar street name or number components.
Question 4: In USPS address standardization, what does the 'secondary address line' typically contain?
- The city, state, and ZIP Code
- The apartment, suite, unit, or floor number (Correct answer)
- The carrier route and walk sequence number
- The country name for international addresses
Correct answer: The apartment, suite, unit, or floor number
The secondary address line contains unit designators such as APT, STE, UNIT, or FL followed by the identifying number or letter.
Question 5: How does SuiteLink processing improve CASS matching for business addresses?
- It adds missing ZIP+4 codes to business P.O. Box records
- It appends secondary suite information to business addresses that lack it (Correct answer)
- It validates that business names match registered USPS delivery points
- It converts business route addresses to standard city-style format
Correct answer: It appends secondary suite information to business addresses that lack it
SuiteLink attempts to append missing suite or floor information to business addresses by matching the firm name to USPS secondary address data.
Question 6: What CASS output code indicates that a matched address is vacant with no mail delivery?
- DPV indicator 'N'
- Vacancy indicator 'Y' (Correct answer)
- No-Stat code 'Y'
- DPV footnote 'CC'
Correct answer: Vacancy indicator 'Y'
The Vacancy Indicator 'Y' from DPV processing flags a delivery point as currently vacant, though the address itself is valid.
Question 7: When standardizing a directional prefix in an address like '123 North West Oak St', CASS software should:
- Output '123 NW Oak St' combining the two words into one directional (Correct answer)
- Output '123 North West Oak St' preserving the original form
- Output '123 N W Oak St' abbreviating each word separately
- Flag the address as ambiguous and leave it unmatched
Correct answer: Output '123 NW Oak St' combining the two words into one directional
USPS standardization combines 'North West' into the single directional abbreviation 'NW' per Publication 28 directional standards.
