QR codes for corrugated boxes and cartons

A corrugated box is the easiest thing for a copier to reproduce: same size, same print, same logo. A unique QR sticker on each box is the one part they can't make up, and it tells your buyer and your team which boxes are really yours.

Why the box itself needs the code

Copied products usually travel in copied cartons. Printing your logo more clearly doesn't help, because the copier reproduces that too. A sticker that carries a different secure code on every single box does something print can't: each scan is checked against the codes you actually issued, and every scan is recorded with its time and city.

What goes on the sticker

  • A unique QR code per box, encrypted so codes cannot be guessed or made up
  • Your logo and brand name
  • Your ISI mark, with the IS and CM/L numbers typeset in clear text so they stay readable when printed small
  • Serial number, batch or lot details and, if you want, a support number
  • A short line telling the buyer what the scan does, like “Scan to verify” or “Scan for warranty”

Sizes and printing

The compact 1-inch sticker is designed for carton flaps and product tags, and larger layouts are available when you have room. You download stickers as a ZIP of images or as a print sheet PDF that opens in CorelDRAW and similar tools, so your own label printer or packaging vendor can run them. Every batch can be printed in several runs, and the dashboard keeps track of which codes went out in which run.

Where it fits in your dispatch

Stick the label on the outer carton, on the product, or both. For products sold loose from a master carton, put the code on each unit and keep the carton as a plain shipper. If the batch carries a warranty, the activation window starts when the first buyer confirms the purchase, and a product can only be confirmed as sold once.

For packaging printers and box makers

If you print corrugated boxes or labels for brands, you can offer secure QR codes as part of the job. The brand gets its own dashboard; you supply the printed stickers or print the code straight onto the box.

Common questions

Can the QR be printed directly on the corrugated box?

Yes, as long as each box gets its own code, which needs variable-data printing. Most brands find it simpler to print stickers and apply one per box before dispatch.

What size should the QR sticker be on a carton?

The standard compact sticker is 1 inch (25.4 mm) square, which phones scan comfortably from normal reading distance. Larger layouts are available if you also want more text on the label.

Does the buyer need a special scanner?

No. Any smartphone camera or QR scanner app opens the result page. No app install and no login are needed to see whether the product is genuine.
