A Drug Identification Number (DIN) is a computer-generated eight digit number assigned by Health Canada to a drug product prior to being marketed in Canada.

Effective June 15, 2017, DIN applications must now include a ready-to -print label that follows the new Plain Language Labelling regulations.

DIN products must be manufactured in a facility that follows good manufacturing practices (GMP).  If the facility is based in Canada that business must obtain an establishment licence.   Foreign sites must also show evidence that they are following GMP through a Health Canada licensed importer.

DIN products cannot be sold prior to license issuance. Licensing timelines vary with as fast as 45 days.  During the COVID-19 pandemic, some OTC drug licences such as disinfectants, may be issued in as fast as 2 days.

Health Canada’s fees for drug licence application submissions are due initially and annually thereafter.  The fee varies and increases annually based on the rate of inflation.
