Every product that carries this Downpass label features a unique control number in two places. The number printed at the top is sewn on and can only be seen when the seam is unstitched. The number is repeated at the bottom of the label.

A list of the companies that are authorised to use the Downpass 2016 seal is deposited at a notary/lawyer's office. By checking this, it is possible to confirm whether the product in question, for instance a sleeping bag, coat or down jacket, has a valid control number.
