Pharmaceutical manufacturers must ensure that medicines have a unique serial number, coding the packaging and also sometimes products such as tablets according to current legislation, taking special care that the marking is legible, of high quality and lasts for the life of the medicine.

Coding and marking of pharmaceutical products must ensure the identification of products. Particularly products that are unsafe for people’s health, which, if they are, must be withdrawn from the market immediately. Traceability is also crucial to help combat counterfeit drugs, given the enormous consequences these can cause to people’s health.
