If your order has tracking details, you will find this information on your order dispatch email. If this information is not on your dispatch email, there is no tracking number available. However, if you advise your local delivery office of your name and delivery address they will be able to confirm if your parcel is being held.
If your order is on a tracked service outside of the UK, you may notice that tracking is unavailable whilst the parcel is clearing customs, sometimes it can take up to 10 days to be cleared. Tracking will resume once the parcel is with your local postal service.
