To sell natural health products in Canada, companies must obtain a product license called a Natural Product Number (NPN). To obtain this NPN, detailed information must be provided to, and assessed by the Natural and Non-Prescription Health Product Directorate (NNHPD) of Health Canada.

Once NNHPD has determined that the product is safe, effective, and of high quality, an eight-digit NPN or DIN-HM (Homeopathic Medicine Number) will be granted. This number must appear on the front panel of your label.
