Format comparisons
Choosing between two symbologies or code types? These pages set out the practical differences — digit structure, print size, scanner support and where each one is actually scanned.
UPC vs EAN-13
UPC-A is 12 digits, EAN-13 is 13. Compare digit structure, regional acceptance, print size and check digits, then generate either free.
Code 128 vs Code 39
Code 128 is denser and supports full ASCII; Code 39 is self-checking and universally readable. Compare width, character sets and scanner support.
Static vs dynamic QR codes
Static QR codes are permanent and free; dynamic codes are editable and trackable. Compare cost, analytics, pattern density and lock-in risk.
QR code vs barcode
Linear barcodes identify products at checkout; QR codes carry URLs and data for phone cameras. Compare capacity, damage tolerance and hardware.
ITF-14 vs EAN-13
ITF-14 labels the outer case, EAN-13 labels the consumer unit. Compare digit structure, bearer bars, print size and where each is scanned.
