Can you change a QR code link after printing?

TL;DR You can change where a QR code points after printing only if it is a dynamic code. Static codes have the link built into the pattern, so changing it means reprinting.

Yes, but only if it is a dynamic QR code. A static code has your link built into the pattern, so changing the link means a new code and new prints. A dynamic code points to a short link, and you can change where that short link goes at any time.

Check what kind of code you have

  1. Open your phone camera and point it at the code.
  2. Read the address in the banner before you tap.
  3. Your own website: static, can’t be changed. A QR provider’s short link: dynamic, can be changed in that provider’s dashboard.

How to change the link of a dynamic code

Log in to the service that made it, open the code, paste the new destination and save. With PermaQR that takes a few seconds and the change is live immediately. The printed pattern doesn’t change, so nothing needs reprinting.

Watch out for subscriptions

Many services only keep dynamic codes working while you pay. If you might stop paying one day, the codes you printed stop too. PermaQR codes are paid for once and keep working; there is nothing to renew.

How do I know if my QR code is dynamic?

Scan it and look at the address that opens first. If it is the QR provider’s short link rather than your own website, it is dynamic.

Can I turn a static QR code into a dynamic one?

No. You need a new dynamic code and new prints. After that, every future change is free.

Does changing the link change how the code looks?

No. The printed pattern stays exactly the same. Only the page it opens changes.
