CASS USPS Addressing Standards & Compliance 2 — Questions and Answers
Question 1: Which USPS publication defines the official addressing standards that CASS-certified software must enforce?
- Publication 25
- Publication 28 (Correct answer)
- Publication 65
- Publication 100
Correct answer: Publication 28
USPS Publication 28 (Postal Addressing Standards) is the authoritative reference that CASS-certified systems must conform to.
Question 2: When a delivery address contains both a suite number and a floor designator, which takes address-line priority according to USPS standards?
- Floor designator always comes first
- Suite number is placed on the primary address line (Correct answer)
- Both must be placed on the same line separated by a comma
- Only one secondary designator is permitted per address
Correct answer: Suite number is placed on the primary address line
The suite (unit) designator is placed on the primary address line with the street address; floor information is secondary.
Question 3: A mailer submits an address with 'NORTH' spelled out in the directional field. How should CASS software standardize this?
- Leave it as 'NORTH' because spelled-out forms are preferred
- Abbreviate it to 'N' per USPS standard directional abbreviations (Correct answer)
- Flag it as undeliverable
- Convert it to numeric form '0N'
Correct answer: Abbreviate it to 'N' per USPS standard directional abbreviations
USPS standards require pre- and post-directionals to use the standard two-character abbreviations (N, S, E, W, NE, NW, SE, SW).
Question 4: What is the maximum character length allowed for an address delivery line in a properly formatted USPS address block?
- 35 characters
- 40 characters (Correct answer)
- 50 characters
- 28 characters
Correct answer: 40 characters
USPS Publication 28 specifies a maximum of 40 characters per address line for OCR-readable mail.
Question 5: Which scenario correctly illustrates the use of a 'Dual Address' in USPS addressing?
- An address with both a PO Box and a street address on separate lines (Correct answer)
- An address spanning two ZIP Code zones
- An address with two suite numbers for the same recipient
- An address referencing two different cities
Correct answer: An address with both a PO Box and a street address on separate lines
A dual address contains both a PO Box and a street delivery address; USPS delivers to whichever line immediately precedes the city/state/ZIP line.
Question 6: In CASS processing, what does the DPV (Delivery Point Validation) confirmation indicator 'S' signify?
- The entire address matched to the ZIP+4 file
- Only the primary number matched; secondary number is missing or invalid (Correct answer)
- The address is a non-deliverable location
- The address matched a seasonal delivery point
Correct answer: Only the primary number matched; secondary number is missing or invalid
DPV confirmation code 'S' means the primary address matched but the secondary (unit/suite) information could not be confirmed.
Question 7: Which USPS standard governs the placement of address elements in relation to barcodes on automation-compatible mail?
- DMM 301 (Correct answer)
- DMM 202
- DMM 708
- DMM 500
Correct answer: DMM 301
DMM 301 (Domestic Mail Manual section 301) contains the physical and addressing standards for automation-compatible mailpieces.
