CASS Delivery Point Barcode Standards 4

Question 1

A mailer prints a DPBC using the ZIP Code, plus-4 code, and delivery point. If the ZIP+4 is unknown, what fallback is permitted for POSTNET?

Accepted Answer

Print the 5-digit ZIP barcode only (32 bars)

Answer

When ZIP+4 data is unavailable, mailers may print a 5-digit POSTNET barcode (32 bars) encoding only the 5-digit ZIP Code, though it qualifies for a lower discount tier.

Question 2

For a highrise apartment at 200 Park Ave, Apt 15, what is the POSTNET delivery point?

Accepted Answer

15

Answer

For apartment addresses, the delivery point is the last two digits of the secondary unit number (apartment number), so Apt 15 yields delivery point 15.

Question 3

Which ink characteristic is most critical when printing POSTNET barcodes to ensure machine readability?

Accepted Answer

Ink must provide sufficient contrast against the background to pass infrared scanning

Answer

USPS scanners use infrared light, so barcode ink must provide strong infrared contrast (not just visible contrast) against the mail piece background.

Question 4

What is the USPS term for software that has passed CASS testing and is approved to assign ZIP+4 codes and delivery points?

Accepted Answer

CASS-certified software

Answer

Software that has completed USPS CASS testing and passed is referred to as CASS-certified software, authorized to produce ZIP+4 and delivery point data for mailings.

Question 5

On a standard #10 business envelope, where must the POSTNET or IMb barcode be placed to meet USPS placement standards?

Accepted Answer

The bottom 5/8 inch of the address side, between the left and right edges

Answer

USPS requires the barcode to be in the barcode clear zone: the bottom 5/8 inch of the mail piece face, horizontally clear of the edges.
