USPS Detecting Sorting Errors 3

Question 1

A batch of 500 letters sorted for ZIP 30301 (Atlanta, GA) is accidentally placed on the truck bound for ZIP 30301 in a different sectional center facility's zone. Which document would reveal this dispatch error?

Accepted Answer

The dispatch manifest or truck bill

Answer

The dispatch manifest or truck bill lists which trays and ZIPs are assigned to each outbound vehicle, making it the key document for catching dispatch-level sorting errors.

Question 2

During a tray sort, a clerk sees a letter with an illegible handwritten address. What is the standard USPS procedure?

Accepted Answer

Send it to the Remote Bar Coding System (RBCS) or nixie unit for research

Answer

Pieces with illegible addresses are forwarded to the RBCS or nixie unit where specialists attempt to determine the correct delivery point.

Question 3

A sorter is working a mixed flat case and places a catalog addressed to 'PO Box 450' into a street-delivery carrier's case. What sorting rule was violated?

Accepted Answer

PO Boxes are sorted separately from street delivery routes

Answer

PO Box mail is separated from street delivery mail because PO Boxes are serviced at the post office counter, not by street carriers.

Question 4

A letter addressed to '123 Oak Lane, Apt 4B, Boston, MA 02101' is sorted to a tray for '02110'. What is the nature of this error?

Accepted Answer

ZIP code error routing it to the wrong carrier unit

Answer

The letter was sorted to ZIP 02110 instead of 02101, placing it in the wrong carrier unit for a different part of Boston.

Question 5

When performing a quality check on sorted trays, what is the MOST reliable indicator that a tray contains misrouted mail?

Accepted Answer

ZIP codes on individual pieces do not match the tray label

Answer

Physically verifying that the ZIP codes printed on each piece match the tray label is the most direct method to identify misrouted mail.
