USPS Alphanumeric Code Verification 2

Question 1

A package label shows routing code '4G7-X2B'. The computer record reads '4G7-X28'. Which character contains the error?

Accepted Answer

The final character 'B' vs '8'

Answer

The last character differs: the label shows 'B' while the record shows '8', indicating a letter-digit substitution error.

Question 2

When verifying alphanumeric sort codes, a clerk finds label '22-JKL-09' and record '22-JKL-09'. What is the correct action?

Accepted Answer

Accept it as correct since both codes match exactly

Answer

When the label and record are identical in every position, the code is verified as correct and no error is flagged.

Question 3

Code on envelope: 'B3F-5KM-11'. Code in system: 'B3F-5KN-11'. How many errors are present?

Accepted Answer

One

Answer

Only one character differs: position 8 shows 'M' on the envelope versus 'N' in the system.

Question 4

A ZIP+4 barcode decodes to '90210-3847'. The handwritten label reads '90210-3874'. Which segment contains the discrepancy?

Accepted Answer

The last four digits

Answer

The five-digit ZIP matches, but the add-on digits differ: '3847' vs '3874' is a transposition error in the last four digits.

Question 5

Which of the following alphanumeric codes contains an obvious character omission compared to the standard 8-character format 'XX-NNNN-X'?

Accepted Answer

AB-123-C

Answer

'AB-123-C' has only three digits in the numeric segment instead of the required four, making it one character short.
