Delivery Confirmation Audit
You are auditing eight delivery-confirmation records against the route manifest. Abbreviations are allowed: Ave = Avenue, Ln = Lane, Rd = Road. A record is a match if street number, street name, suffix, and ZIP all agree with the manifest. It is an address error if the street name, suffix, or number conflicts with the manifest range. It is a ZIP error if only the ZIP disagrees. A record with both kinds of conflict is a double error.
Manifest:
- 1400–1499 Birchwood Ave - 60411
- 1500–1599 Birchwood Ave - 60412
- 200–299 Larkspur Ln - 60412
- 700–799 Quarry Rd - 60413
- 900–999 Quarry Rd - 60413
Records:
- 1428 Birchwood Ave, 60411
- 1512 Birchwood Avenue, 60411
- 214 Larkspur Lane, 60412
- 780 Quary Rd, 60413
- 918 Quarry Rd, 60413
- 1540 Birchwood Ave, 60412
- 265 Larkspur Ln, 60411
- 740 Quarry Rd, 60431
1. Classify all eight records. For each error, state exactly which field is wrong and what the correct value should be.
Read the worked answer
- Match. Number in range, name and suffix correct, ZIP correct.
- ZIP error. Address is valid for 1500–1599 Birchwood; ZIP should be 60412, not 60411. 'Avenue' is an allowed abbreviation expansion.
- Match. 'Lane' is allowed for Ln; ZIP 60412 is correct for Larkspur.
- Address error. Street name is misspelled 'Quary'; manifest requires Quarry. ZIP is correct.
- Match. 918 is in the 900–999 range, name and ZIP correct.
- Match. 1540 is in 1500–1599; ZIP 60412 correct.
- ZIP error. Larkspur requires 60412, not 60411.
- ZIP error. 740 Quarry Rd is in 700–799 and the suffix is correct; ZIP should be 60413, not 60431 (digit transposition).
2. Which errors are most likely to cause a misdelivery, and which are most likely only to delay the item? Justify each.
Read the worked answer
Likely misdelivery: records 4 and 8.
- Record 4 has a wrong street name. 'Quary' may fail to match route data, but it also may be auto-corrected to a nearby street, sending the item to the wrong block.
- Record 8 has a valid street but a transposed ZIP. A wrong ZIP can route the item to a different facility entirely, which is the classic misroute path.
Likely delay only: records 2 and 7.
- Both have correct street addresses and only a wrong ZIP within the same local area. The carrier can often sort by street, but the record will fail confirmation and may be pulled for correction, adding a day.
General rule: street-level conflicts risk wrong delivery; ZIP-only conflicts usually add handling delay.
3. You can correct only two records before the carrier loads. Which two do you fix, and what is the correction sequence?
Read the worked answer
Fix records 4 and 8 first, then 2 and 7 if time allows.
Sequence:
- Record 8 - correct ZIP 60431 to 60413. It is the highest risk because an out-of-area ZIP can send the item to the wrong facility, and the fix is a single field.
- Record 4 - correct 'Quary' to 'Quarry'. It is a street-level conflict on a valid block and needs a name correction before sorting.
Records 2 and 7 are ZIP-only errors on correct streets and can be corrected at the next scan point with less risk. Priority is driven by consequence: wrong-facility routing first, wrong street second, local ZIP mismatch last.
