Drug Identification Number (DIN) Registration

You may wish to register your Drug Identification Number (DIN) if you want to sell your product on the Canadian market as an NHP or if your product is considered a drug.

We can assist you with preparing and filing Drug Identification Number (DIN) applications and meeting the necessary requirements set out by Health Canada.

What is a Drug Identification Number (DIN)?

A Drug Identification Number (DIN) is a computer-generated 8-digit number, assigned to a drug product prior to being sold in Canada.  Health Canada regulates drug products, including OTC drugs (Over-the-Counter medicines sold directly to consumers without a prescription) to ensure they are safe to use.

It uniquely identifies all drug products sold in a dosage form in Canada and is located on the label of prescription and over-the-counter drug products that have been evaluated and authorized for sale in Canada.  It is very important as this allows pharmacies to dispense the correct drug and helps ensure safe patient care.

Who needs to register their DIN?

Anyone who wishes to sell their product as an NHP or as a drug in Canada must have their DIN registered with Health Canada. A Drug Identification Number (DIN) is a unique identifier for health products and devices, including drugs, biologics and medical devices. The DIN numbers are assigned by Health Canada after a review of the product’s chemistry, manufacturing methods, quality assurance systems and packaging material used. If you want to market your product in Canada as either an NHP or as a drug, you will need one or both of these numbers.
