GO! Express & Logistics Tracking. Free & Online.

The company behind this tracker is GO! Express & Logistics Deutschland GmbH of Bonn, whose fact sheet names Niederaula in Hesse as the central hub. GO! says it has its own national companies in eight countries, Switzerland among them, plus cooperation partners in further neighbouring countries.

TrackParcel reads the English version of GO!'s German tracker. Parcels from the Swiss company, which GO!'s country menu also links for Liechtenstein, are tracked on a separate system under GO! Schweiz.

GO!'s tracking page asks for a tracking number, and its app for the waybill number. For a 12-digit number starting 158, Auto-Detect does list GO! Express & Logistics, but last, behind Tirupati and other couriers that use 12-digit numbers. Picking GO! from the courier list by hand sends the number straight to GO!.

TrackParcel sets no length or prefix check of its own for GO! numbers. Once the search box has capitalised letters and removed spaces, dots, slashes and most hyphens, whatever remains is sent, so a mistyped number is judged by GO!'s own tracker. If what is left is over 50 characters, or holds a symbol other than a kept hyphen or underscore, such as a plus sign between digits, it is refused as an invalid number first.

TrackParcel asks GO!'s German tracker for its English page, the same service behind the tracking form on GO!'s site. From each scan row it keeps the status phrase, the place, and the date and time, and it lists the newest scan first.

The pickup and delivery places in GO!'s reply become the origin and destination, with labels such as Pickup at removed. Without them, the oldest scan's place stands in for the origin, and the newest scan's place for the destination only once the parcel is delivered. TrackParcel takes no expected delivery date from GO!'s page. Unless a delivery or return date is shown, the result's date row therefore gives the oldest scan's date: Picked up when a scan that day reports a completed pickup, First scan otherwise.

TrackParcel calls a number not found in two cases only: GO!'s tracking service, not a web error page, answers that the page does not exist, or its reply holds no scan row TrackParcel can read and contains wording such as not found, no shipment or not yet received. The German keine Information, noch nicht erhalten and nicht gefunden count the same way.

When a reply has no history rows and none of that wording, TrackParcel treats GO! as unavailable, not the parcel as missing. If every history row is unreadable, even a lone heading row, the lookup counts as a reading error unless that wording is present.

For questions about a shipment, GO!'s tracking page sends you to your local GO! station, found with its station finder from a postcode or city. The contact form on GO!'s site also asks for a postcode, which it needs to forward the request to your station.
