Question 1

How many additional digits does a ZIP+4 code append to the base 5-digit ZIP Code?

Accepted Answer

4

Answer

A ZIP+4 code consists of the standard 5-digit ZIP Code plus a 4-digit add-on, separated by a hyphen, enabling more precise mail sorting.

Question 2

What is the role of the 'delivery point' code in the full USPS delivery point barcode system?

Accepted Answer

It provides a 2-digit code representing the specific mailbox, unit, or delivery stop

Answer

The delivery point is a 2-digit code derived from the last two digits of the primary address number (or PO Box number), completing the 11-digit delivery point barcode.

Question 3

Which address components are primarily used to determine and assign a ZIP+4 code suffix?

Accepted Answer

Street name, primary number, and secondary number

Answer

The ZIP+4 suffix is derived by matching the street name, primary number (house number), and secondary number (unit) to USPS address range records within the base ZIP Code.

Question 4

What is the primary function of LACSLink in USPS address processing?

Accepted Answer

Converts rural route and highway contract addresses to city-style street addresses

Answer

LACSLink (Locatable Address Conversion System) translates old-style rural route addresses (e.g., RR 2 Box 5) into modern city-style addresses to improve deliverability and automation.

Question 5

In CASS processing terminology, what is a 'No-Stat' address?

Accepted Answer

A valid address in the USPS database that is currently not receiving active mail delivery

Answer

A No-Stat address exists in USPS records and may be DPV-confirmed, but it is flagged as not currently active for mail delivery (e.g., seasonal, vacant, or under construction).
