USPS Mail Processor 3

Question 1

A processor is verifying two address records. Record 1: '2290 Westchester Ave Apt 4B'. Record 2: '2290 Westchester Ave Apt 4D'. What is the error?

Accepted Answer

Apartment letter differs

Answer

The apartment designator differs between the two records — '4B' versus '4D' — making them distinct addresses.

Question 2

During automated processing, a flat enters the OCR reader upside down, causing an unreadable scan. What is the standard corrective procedure?

Accepted Answer

Manually key-enter the address and reintroduce the piece

Answer

When OCR fails to read a piece, the processor manually keys in the address so it can be routed correctly before reintroducing it to the stream.

Question 3

A mail processor checks two serial numbers: A) 88-4471-009 and B) 88-4471-090. What type of error is present?

Accepted Answer

Transposition error

Answer

The last three digits '009' versus '090' show that two digits have been swapped, which is a transposition error.

Question 4

A package addressed to 'Springfield, IL 62701' is placed in a tray labeled 'Springfield, IL 62702'. What should the processor do?

Accepted Answer

Move the package to the correct 62701 tray

Answer

Even a one-digit ZIP difference routes mail to a different delivery area, so the package must be moved to the tray matching ZIP 62701.

Question 5

Which scenario represents an 'omission error' on a mail address?

Accepted Answer

The directional 'N.' left out of '4500 N. Broadway'

Answer

An omission error occurs when a required element — such as a directional prefix — is missing entirely from the address.
