If you are printing cartons or leaflets for medications, standard retail barcodes are not enough. Learn how assembly lines use Pharmacode (Laetus) to prevent fatal packaging mix-ups.
During pharmaceutical manufacturing, packaging is loaded into machines at high speeds. If a paper leaflet for a severe allergy medication accidentally gets inserted into a carton meant for standard aspirin, the consequences for the patient can be fatal.
To prevent this, the industry relies on Pharmacode (also known as the Laetus Code). Unlike UPCs meant for grocery store checkouts, Pharmacode is printed directly on the hidden flaps of cartons and the edges of instruction leaflets. High-speed optical scanners verify the code before the machine folds the box, ensuring the product and the packaging match perfectly.
Pharmacode is radically different from modern barcodes. It doesn't encode text, letters, or long data strings. It is purely mathematical.
Developed by Laetus, Pharmacode operates as a binary system. It utilizes only two types of bars: a narrow bar and a wide bar. Because it does not use complex start or stop characters, it can be printed in a multitude of colors (as long as there is contrast) and remains highly readable even if the printing ink smears slightly during high-speed production.
Single Integer Only: A Pharmacode only represents a single whole number. It cannot hold decimal points, letters, or punctuation.
Strict Range (3 to 131070): The code mathematically translates the given number into a sequence of thick and thin bars. It must be at least 3, and cannot exceed 131,070.
The Directional Reading Quirk
Because Pharmacode lacks start and stop characters, scanning it from left-to-right produces a completely different number than scanning it from right-to-left. Pharmaceutical manufacturers intentionally use this feature to detect if a leaflet has been inserted upside-down into the packaging machine.

Range Exceeded
The integer must be between 3 and 131,070.
