Códigos de barras para entrega de última milla: Del centro de distribución a la puerta
Barcode scanning in last-mile delivery — route loading, proof of delivery, exception handling, and customer notification triggers.
Last-Mile Delivery Barcodes: From Hub to Doorstep
The last mile, from the delivery hub to the customer's door, is the most expensive and complex segment of the delivery chain. Barcode scanning at each last-mile event creates visibility, triggers customer notifications, and provides proof of delivery.
Last-Mile Barcode Events
| Event | Scan Type | Purpose |
|---|---|---|
| Hub arrival | Inbound scan | Package enters the delivery hub |
| Sort to route | Scan to route assignment | Package assigned to delivery vehicle |
| Vehicle load | Load scan | Package confirmed on the truck |
| Delivery attempt | Doorstep scan | Proof of delivery or attempt |
| Exception | Exception scan | Package redirected, refused, or damaged |
| Return to hub | Return scan | Undeliverable package returns |
Route Loading
Before departure, the driver scans each package onto the truck:
- Driver scans their ID badge
- Scans each package barcode as it is loaded
- System verifies all packages for the route are loaded
- Alerts for any missing packages
- Driver departs with a confirmed manifest
This prevents the costly error of leaving packages at the hub.
Proof of Delivery
At the doorstep, the driver:
- Scans the package barcode
- System records GPS coordinates and timestamp
- Driver captures a photo of the delivery location
- Customer receives automated delivery notification
- Scan data serves as legal proof of delivery
Customer Notification Triggers
Barcode scans trigger real-time customer communications:
| Scan Event | Notification |
|---|---|
| Out for delivery | "Your package is on the truck" |
| Near destination | "Your delivery is arriving soon" |
| Delivered | "Your package has been delivered" + photo |
| Attempted | "We tried to deliver. Next attempt..." |
| Exception | "There's an issue with your delivery" |
Delivery Exception Handling
When a package cannot be delivered:
- Driver scans the package barcode
- Selects an exception reason (no access, addressee unknown, refused)
- System records the exception with GPS and timestamp
- Package is scanned back onto the truck
- Re-delivery attempted or package returned to sender
Last-Mile Barcodes for Lockers and Pickup Points
Parcel lockers and pickup points use barcodes for:
- Locker assignment: Package barcode linked to a specific locker compartment
- Customer pickup: Customer scans a pickup code (from email/SMS) to open the locker
- Timeout return: Uncollected packages scanned for return after the pickup window
Driver Performance Metrics
Barcode scan data enables driver performance tracking:
| Metric | Measurement |
|---|---|
| Packages per hour | Delivery scans / route hours |
| First attempt success rate | Delivered / (delivered + attempted) |
| On-time delivery | Scans within delivery window / total scans |
| Route compliance | Actual stop sequence vs planned sequence |
