QR codes for product packaging
Packaging has the longest lag between printing and reading of anything in this list. A carton printed today may be opened by a customer eighteen months from now, in a world where your site has been rebuilt and the page it pointed at is gone.
What changes behind the code
- Your website structure — the single most common reason an old pack code 404s.
- Product information, instructions, and ingredient or compliance details.
- Support and warranty destinations, which move when a company changes systems.
- Campaigns, which run for weeks against packaging that lasts for years.
What a reprint costs here
This is the worst case in the list. Packaging is printed in the tens or hundreds of thousands, is committed to well ahead of demand, and sits in warehouses and on retail shelves that you cannot reach. A wrong destination is not correctable at any price — the only options are to wait out the inventory or to pulp it.
What to point it at
- A stable product page keyed to the SKU rather than to a campaign.
- Instructions, assembly, or care information that you expect to revise.
- Registration, warranty, or reordering, which is where packaging codes earn their place.
Printing it
Raise the error correction for packaging
Codes on cartons and labels get creased, scuffed, and printed on curved or textured surfaces. A higher error-correction level costs a slightly denser code and buys real tolerance for damage.
Give every SKU its own code
One code across a product line saves nothing and costs you the ability to send people to the right place later. A code per SKU is the version that stays useful.
