CASS USPS Addressing Standards & Compliance 3

Question 1

A ZIP+4 code appended during CASS processing could not be determined for a valid street address. What is the most likely cause?

Accepted Answer

The address is a new development not yet in the AMS database

Answer

New developments and recently built addresses may not yet be reflected in the Address Management System (AMS) database, preventing ZIP+4 assignment.

Question 2

How does CASS certification treat a Secondary Address Unit (SAU) that exists in the database but was not provided in the input address?

Accepted Answer

It flags the address as requiring secondary information

Answer

When CASS detects that a secondary unit is required but absent, it sets the DPV footnote indicating missing secondary information rather than fabricating the unit.

Question 3

Which suffix would CASS software assign when standardizing the street type 'AVENUE' in an output address?

Accepted Answer

AVE

Answer

The USPS standard abbreviation for 'AVENUE' is 'AVE' as listed in the official suffix abbreviation table in Publication 28.

Question 4

What is the purpose of the LACS (Locatable Address Conversion System) component in CASS processing?

Accepted Answer

Converts rural route addresses to city-style street addresses

Answer

LACSLink converts old rural route and highway contract route addresses to new city-style street addresses when rural areas are urbanized.

Question 5

A mailer's address file shows '1600 PENNSYLVANIA AVE NW, WASHINGTON DC 20500'. Which component is the post-directional?

Accepted Answer

NW

Answer

The post-directional 'NW' follows the street suffix 'AVE' and indicates the directional quadrant of the address within the city grid.
