It doesn't get scanned if you put your parcel in the red box. I was putting my parcels in the red box at the business centre, so I didn't have to queue for ages, and they weren't scanning them. I found that trackiing only showed up the day they delivered. They informed me I had to come into the business centre and lodge them with staff to get tracking. I thought if we had to pay for tracking they would provide the service if we put parcels in the red boxes, but Nooooo!
