To track your package or see your order status you need to find your shipping confirmation that was emailed to you. This email will be from firstname.lastname@example.org
In the email, underneath where the items of your order are listed, there is a tracking number. It will be a long number and they always begin with SH. Click on this number to be taken to the DHL website, where you'll find updates on your order.
Or, if you wrote down your tracking number, go straight to the DHL website here.
It may take up to 24 hours from the shipping confirmation email being sent for the tracking information to become available.
