CASS Address Hygiene & Data Quality 2 — Questions and Answers
Question 1: Which USPS standard defines the format and content rules for a valid delivery address element?
- Publication 28 (Correct answer)
- Publication 65
- DMM 602
- AIS Technical Guide
Correct answer: Publication 28
USPS Publication 28 (Postal Addressing Standards) defines the official rules for address format and content.
Question 2: When standardizing a street name, 'Saint' should be abbreviated to which USPS-approved abbreviation?
- ST (Correct answer)
- STE
- SNT
- S
Correct answer: ST
USPS abbreviates 'Saint' as 'ST', the same abbreviation used for 'Street', disambiguated by context.
Question 3: A record contains '4500 Main St Apt 3B' but the USPS database shows the building only has units 1-20. What is the correct action?
- Flag the secondary address as undeliverable (Correct answer)
- Remove the secondary designator entirely
- Accept the address as-is
- Convert to a PO Box
Correct answer: Flag the secondary address as undeliverable
When a secondary unit does not match the USPS range for that building, it should be flagged as undeliverable.
Question 4: What does a DPV 'Footnote S' indicate about an address?
- The primary number is confirmed but the secondary is missing (Correct answer)
- The address does not exist in the DPV file
- The record matched a PO Box
- The ZIP Code was corrected
Correct answer: The primary number is confirmed but the secondary is missing
DPV Footnote S means the primary number matched but the secondary information is missing from the address.
Question 5: Which type of address record in the USPS AMS database indicates a building where all units share one delivery point?
- High-rise default record (Correct answer)
- Rural route record
- General delivery record
- Unique ZIP record
Correct answer: High-rise default record
A high-rise default record is assigned when a high-rise building's unit breakdown is not individually coded in the AMS.

- Convert rural route addresses to street-style addresses (Correct answer)
- Assign ZIP+4 codes to PO Boxes
- Validate secondary address units
- Identify duplicate records in a mailing list
Correct answer: Convert rural route addresses to street-style addresses
LACSLink converts old rural route and highway contract route addresses to new city-style (911) addresses.

- Street suffix standardization and spelling correction (Correct answer)
- Secondary address validation
- ZIP+4 assignment
- DPV confirmation
Correct answer: Street suffix standardization and spelling correction
Correcting a misspelled street suffix such as 'Avneue' to 'Avenue' is a standardization and spelling correction operation.
