Save the seller order, tracking history, Delivery Notice and every attempted correction. If UPS returns the parcel, loses custody or requests a shipper-only action, contact the merchant because it owns the sales obligation and often the shipping contract. Do not promise that the recipient can file or collect every carrier claim.
At pickup, use the identity and location instructions shown for that package; names and addresses should match the shipment record. Avoid links from delivery-text messages until the waybill is confirmed on ups.com. If a parcel appears damaged at pickup or delivery, document the exterior before opening and preserve packaging while the merchant/UPS gives the applicable inspection instructions. Record the pickup address and hours from the live shipment page before travelling, because access-point availability can change. Save the final tracking event after collection or return so the merchant receives a complete custody record.
