What's the difference between a static and a dynamic QR code?
A static QR code holds a fixed web address; a dynamic one points to a short link you can edit and track. Here's when each makes sense, and why dynamic wins for marketing.

The short answer
A static QR code has the destination baked in: once it's printed, the address it opens can never change, and it records no scans. A dynamic QR code instead encodes a short link you control, so you can change where it points after printing and see how many people scanned it. For anything you print or can't easily reissue, a dynamic QR code is the safer choice.
Key points
- A static QR code stores the web address directly in the pattern, so it can't be changed or tracked once it's made.
- A dynamic QR code stores a short link instead, so the real destination can be edited later and scans are counted.
- Dynamic codes are the right call for anything printed — packaging, posters, business cards — where reissuing the code is costly.
- Static codes are fine for throwaway or one-off uses where you'll never need to change the destination or measure scans.
- On Shortlen, QR codes are dynamic: they ride on a short link, so you get editing and scan analytics on the same plan.

Both kinds of QR code look like the same square of dots, but what’s inside them is different, and it changes what you can do later. A static QR code has the destination written straight into the pattern. A dynamic QR code has a short link written into it instead, and that short link decides where scanners actually end up — which means you can change it, and count it, after the code is already out in the world.
Why “static” means “stuck”
When you make a static QR code, the full web address is encoded directly into the black-and-white pattern. That’s fine until the day the address needs to change — a campaign page moves, a product is renamed, a URL has a typo. Because the destination is baked in, there’s no way to fix it; you have to generate a brand-new code and reprint everything it appeared on. A static code also has nowhere to record a scan, so you can’t tell whether ten people or ten thousand used it.
Why dynamic codes win for anything printed
A dynamic QR code encodes a short link, not the final address. The short link sits in the middle: scanners open it, and it forwards them to wherever you’ve pointed it. That one layer of indirection is what makes the difference — you can edit where the link goes after the code is printed, and because every scan passes through the short link, each one is counted. For anything you commit to print — packaging, posters, menus, business cards — that’s the safer choice, because reprinting is exactly the thing you want to avoid.
When a static code is fine
Static codes aren’t wrong, they’re just limited. If you’re generating a code for something short-lived or one-off — a slide you’ll show once, a link you know will never change, a quick personal share — a free static generator does the job and nothing is lost. The question to ask is simple: might this destination ever need to change, and would I want to know how many people scanned it? If either answer is yes, use a dynamic code.
How this works on Shortlen
On Shortlen, QR codes are dynamic by design: each one rides on a short link, so you get the same editing and scan analytics you’d get from any Shortlen link, on the same plan. That means a code you print today can point somewhere new next month, and you’ll see how it’s performing in the meantime.

Questions people ask
Can I change a static QR code after printing it?
No. A static QR code has the destination encoded directly in its pattern, so the only way to change where it goes is to generate and reprint a new code. That's the main reason dynamic codes exist.
Does a dynamic QR code expire?
The code keeps working as long as the short link behind it does. On Shortlen your links stay active until you remove them, so a printed dynamic code keeps working — see how expiring links work if you ever want one to stop on purpose.
Do dynamic QR codes cost more?
They rely on a shortener to hold and track the link, so they're usually part of a paid plan rather than a free one-off generator. The trade is worth it when you can't easily reprint a code or you want to know how many people scanned it.
