Accepted Answer

ZIP code digit transposition error

Accepted Answer

Delayed delivery requiring re-sorting at the destination facility

Answer

Mail sorted to the wrong ZIP bin within the same city must be identified and re-sorted, causing delivery delays.

Question 4

Which detail on a mailpiece should a sorter check FIRST to confirm correct bin placement?

Accepted Answer

Destination ZIP code

The destination ZIP code is the primary routing indicator and should be verified first when confirming correct bin placement.

Question 5

A flat is labeled '3rd Floor, 500 Main St, Denver, CO 80203' but was sorted with mail for '500 Main St, Denver, CO 80203' without floor distinction. What error risk does this create?

Omitting the secondary address (floor/suite/unit) from sort consideration risks the carrier delivering to the wrong unit within the building.
