USPS Alphanumeric Code Verification 3

Question 1

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

Accepted Answer

No, the last character differs: Q vs O

Answer

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

Question 2

Which pair of codes represents a TRANSPOSITION error?

Accepted Answer

'A1B2' vs 'A12B'

Answer

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

Question 3

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

Accepted Answer

Pass the code as correct — it matches the reference exactly

Answer

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

Question 4

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

Accepted Answer

Transposition

Answer

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

Question 5

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?

Accepted Answer

Zero errors — both codes match

Answer

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