Alphanumeric Code Verification Flashcards

Code string 'TZ8-002-AQ' is being verified against 'TZ8-002-AO'. A new clerk marks this as correct. Is the clerk right?

Answer: No, the last character differs: Q vs O

The final character is 'Q' on the item but 'O' in the record; even a single character mismatch must be flagged as an error.

Which pair of codes represents a TRANSPOSITION error?

Answer: 'A1B2' vs 'A12B'

'A1B2' vs 'A12B' shows the '1' and 'B' swapped positions, which is the definition of a transposition error.

A distribution code reads 'NDC-10-M'. The reference sheet lists it as 'NDC-10-M'. After verification, what should the clerk do?

Answer: Pass the code as correct — it matches the reference exactly

An exact match between the item code and the reference means the code is correct and should be passed without flagging.

Code '77W-EE9-04' is compared to '77W-EE9-40'. What kind of error appears in the last two digits?

Answer: Transposition

The digits '04' and '40' are the same two characters in reversed order, which is a transposition error.

A clerk must verify 20 codes per minute. She checks 'RT-5500-ZZ' against 'RT-5500-ZZ' and 'MV-3310-AB' against 'MV-3310-AB'. How many errors did she find?

Answer: Zero errors — both codes match

Both codes are identical to their reference counterparts, so no errors are present.

A label shows 'USPS-BM-0047A'. The manifest lists 'USPS-BM-0074A'. Which segment contains the error?

Answer: The numeric segment '0047' vs '0074'

The numeric portion reads '0047' on the label but '0074' in the manifest, a transposition of the interior digits.

An extra character appears in one code: '55-KK-88X' vs the reference '55-KK-88'. What type of error is this?

Answer: Insertion error

The item code has one additional character ('X') that does not appear in the reference, making this an insertion error.
