When Do You Need Barcodes?
Barcodes are essential for retail products (EAN-13, UPC-A), logistics (Code 128, ITF-14), pharmaceutical packaging (Pharmacode), and inventory management (Code 39). FreeQRGen generates all 8 major formats.
Choosing the Right Format
EAN-13 and UPC-A are standard for retail. Code 128 is the most versatile — it encodes any ASCII character. Code 39 is widely used in defense and automotive industries. Each format has specific input rules shown inline.
