Read the first 7 Alphanumeric Code Verification flashcards as text

  1. A route code '8C-ALPHA-3' is compared to '8C-APHA-3'. What is the error?

    Answer: A letter was deleted from the middle segment

    The middle segment 'ALPHA' in the reference becomes 'APHA' in the item, with the letter 'L' missing — a deletion error.

  2. Which of the following best describes the purpose of alphanumeric code verification on the USPS Error Detection Test?

    Answer: To identify discrepancies between codes on items and their records

    Alphanumeric code verification tasks require examiners to spot any discrepancy between a code printed on an item and the corresponding entry in a reference record.

  3. Compare 'LM-2299-QR' (label) with 'LN-2299-QR' (system). Which position contains the error?

    Answer: Position 2 (M vs N)

    The second character is 'M' on the label but 'N' in the system; all other characters are identical.

  4. A supervisor tells a clerk that codes '009-ZZ-T' and '009-ZZ-T' are a matched pair. The clerk flags them anyway. Is the clerk correct?

    Answer: No, the codes are identical and should not be flagged

    Identical codes represent a correct match; flagging them is an error on the clerk's part.

  5. Code 'FG-7734-JK' is on the parcel. The log shows 'FG-7334-JK'. How many digit errors are present?

    Answer: One

    Only the third digit differs: '7' on the parcel versus '3' in the log, yielding exactly one error.

  6. A code verification task shows: Item: 'W44-PQ9-BB' | Record: 'W44-PQ9-BB'. A second item: 'X12-RR8-ZZ' | Record: 'X12-RR8-ZZ'. A third item: 'M55-CC1-GH' | Record: 'M55-CC1-GI'. How many total errors exist across the three items?

    Answer: One

    Only the third item has an error ('H' vs 'I' in the last character), so there is exactly one error total.

  7. On the USPS exam, you see: Label '32B-00Y-55' vs Record '32B-00Y-55Z'. Which error type does this represent?

    Answer: Insertion — the record has an extra character

    The record contains one additional character ('Z') that is absent from the label, making this an insertion error in the record.
