Watchlist & Alerting

The watchlist identifies tickets or alerts from active deliveries.

Tickets in the Watchlist

While a package is on its way, parcelLab identifies the need for action through tickets:

Ticket category


Invalid ID

We couldn't find this tracking number in the carrier's database and thus we are not able to track this shipment.

Delayed dispatch

The shipment was not dispatched in time, we measure it by "on the way", the key indicator is drawn either shipment-related via the field "send_date" or generalised via a construction like "Created on" + x hours.


A shipment was created and registered at the carrier (EDI transmission successful), but there was no inbound scan within the usual period of time, which means that the parcels did not arrive at the carrier. This may be because it was forgotten and not loaded, the bridge has stopped somewhere, or the label was damaged during the first transport.

Failed attempt

The carrier attempted delivery but was unsuccessful. The next action will be listed if explicitly stated by the carrier.


We have detected a delay in the delivery process. This can originate from an explicit announcement from the carrier (see below) because a parcel did not take the required route to its destination, or because there was too long between scans. In this case, we know that the recipient will receive their package a day later and recommend an automatically generated notification.


An exception is a delay that has escalated. The reason for the delay could not be resolved on the next working day. These cases can hardly be handled automatically and thus we pass it on to the customer service.

Lead time exceeded

A retroactive consideration once a package has been delivered. It compares "Runtime Carrier" with the configured SLA, which can be defined by destination country and carrier.

Failed delivery

A shipment is confirmed to have not been delivered, the return has already been detected. This also recognizes shipments without an explicit return status report.
