USPS Address Management 2 — Questions and Answers
Question 1: What is the correct format for a ZIP+4 code?
- 12345-67
- 12345-6789 (Correct answer)
- 1234-56789
- 123456789
Correct answer: 12345-6789
ZIP+4 codes use a 5-digit ZIP followed by a hyphen and 4 additional digits.
The ZIP+4 code consists of the standard 5-digit ZIP code plus a 4-digit extension separated by a hyphen (e.g., 10001-1234). The extra digits help sort mail to specific delivery routes, buildings, or floors.
Question 2: CASS certification ensures:
- Employee background checks
- Address accuracy and standardization (Correct answer)
- Vehicle maintenance compliance
- Package weight verification
Correct answer: Address accuracy and standardization
CASS (Coding Accuracy Support System) certifies address validation software.
CASS certification validates that address-matching software meets USPS accuracy standards for standardizing addresses, assigning ZIP+4 codes, delivery points, and carrier routes. It's required for automation rate discounts.
Question 3: A Delivery Point Barcode (DPBC) contains how many digits?
- 5
- 9
- 11 (Correct answer)
- 12
Correct answer: 11
DPBC adds 2 delivery point digits to the ZIP+4, creating an 11-digit code.
The Delivery Point Barcode encodes the full 11-digit delivery point: 5-digit ZIP + 4-digit extension + 2-digit delivery point code. This uniquely identifies every deliverable address in the U.S.
Question 4: NCOA (National Change of Address) data is valid for:
- 6 months
- 18 months
- 48 months (Correct answer)
- Indefinitely
Correct answer: 48 months
NCOA records are retained for 48 months (4 years) from the move date.
The USPS NCOA database contains change-of-address records filed by individuals and businesses for 48 months. Mailers must process their lists through NCOA within 95 days of a mailing to receive automation rates.
Question 5: What does 'AMS' stand for in USPS address management?
- Automated Mail Sorting
- Address Management System (Correct answer)
- Annual Mailing Schedule
- Approved Mail Standards
Correct answer: Address Management System
AMS is the Address Management System used by USPS for address data.
The Address Management System (AMS) is the USPS database containing address information for all delivery points in the United States. It includes ZIP codes, carrier routes, and delivery point data used for mail processing.
Question 6: The purpose of DPV (Delivery Point Validation) is to:
- Validate employee credentials
- Confirm an address is a valid delivery point (Correct answer)
- Calculate postage rates
- Track package delivery
Correct answer: Confirm an address is a valid delivery point
DPV confirms that an address actually exists as a valid USPS delivery point.
Delivery Point Validation confirms whether a specific address (including apartment/suite number) is a valid, deliverable address in the USPS database. This reduces undeliverable-as-addressed (UAA) mail and improves delivery accuracy.
