What this audit checks
Authentication & access
- USPS UserID + Password still authenticate (no ‘Authorization Failure’)

Service-day promises
- Priority Mail OTD < 92% rolling 30D
- Priority Express overnight OTD < 95%
- First-Class Package multi-day OTD < 88%
- Ground Advantage multi-day OTD < 85%
ZIP zone performance
- Any ZIP zone OTD < 85% (regional weakness)
- Alaska / Hawaii / US territories transit > 7 days
- Rural-zone (Zone 8+) OTD < 80%
SCAN-form & label integrity
- SCAN-form gap > 2% (label printed but no acceptance event)
- Service-Type-Code mismatch > 0.5% (label paid Priority but mailed First Class)
- Tracking-number reuse rate > 0.1%
- Address-correction surcharge rate > 1% (data-quality signal)
Insurance, claims & cost
- Lost-parcel rate > 0.5% on insured shipments
- Insurance-claim resolution time > 60 days median
- Damaged-parcel claim rate > 0.5%
- Avg cost / shipment up >10% vs prior period (USPS rate adjustment signal)
- Claim value as % of USPS revenue > 1% rolling 90D
Cross-channel: revenue at risk (the kill-shot area)
- Cross-channel: late shipments joined to commerce_sibling orders -> revenue at risk per channel
- Cross-channel: SCAN-form gaps correlated with order_ref - which channels have the most invisible parcels
- Cross-channel: open claims with no Jira tracker_item -> CS coverage gap
- Cross-channel: Priority Mail upsell ROI vs First-Class (when used as alternatives on same order_ref)
