Question 1

The Intelligent Mail Barcode (IMb) is composed of how many bars?

Accepted Answer

65

Answer

The IMb uses 65 bars to encode up to 31 digits of routing and service information. The 65-bar count is the physical structure of the barcode symbol, while 31 digits represent the data payload.

Question 2

Accepted Answer

Confirm that an address corresponds to an actual deliverable point in the USPS database

Under USPS Move Update standards, address lists must be updated within how many days before the mailing date?

Accepted Answer

95 days

Question 5

According to USPS addressing standards, a secondary address element (such as APT or STE) should appear:

Accepted Answer

On the delivery address line, after the street name and number
