Can QR codes expire?

Static codes never expire

A static QR code encodes its data directly in the pattern. There is no server, no account, and no clock. The code on paper is the data. As long as the pattern is legible and its destination exists, it works — next year or next decade. The codes generated on this site are static and have no expiry, no watermark, and no subscription.

Dynamic codes can expire

A dynamic code encodes a short redirect URL hosted by a provider. Every scan bounces through that provider's server. That indirection is what makes the code editable and trackable — and also what makes it fragile:

• Subscription lapses — stop paying and the redirect often stops resolving, killing every printed code at once.
• Free trials end — a "free" dynamic code may work only during a trial, then go dark.
• The provider shuts down — if the company folds, the redirect domain may disappear entirely.

What actually makes a code stop working

Beyond the static/dynamic split, a few things can break any code:

• The destination dies. Even a static code is useless if the website it points to goes offline or the page is deleted. The code is fine; the target isn't.
• Physical degradation. Fading ink, scratches, water damage, or tearing can render a printed code unreadable. Print durably and protect it.
• A changed link or username. If you encoded a specific URL or handle and it changes, a static code can't follow — by design.
• An expired domain. If the destination domain lapses, the link breaks regardless of code type.

How to tell if a code is static or dynamic

Before you trust a generator's "free forever" claim, you can often work out which kind of code you're getting:

• Decode it and read the content. Scan your finished code and look at the raw link. If it contains your actual destination (https://yoursite.example/page), it's static. If it shows a short, unfamiliar domain you don't own (a redirect), it's dynamic.
• Check for an account or dashboard. If editing the destination or viewing scans requires logging in, the code is dynamic and tied to that service.
• Watch the wording. "Edit anytime," "track scans," and "manage your codes" all describe dynamic codes with a subscription behind them.
• Density is a hint. A code for a long URL that comes out surprisingly coarse may be hiding a short redirect — i.e. dynamic.

The codes generated here are static: decode one and you'll see exactly the data you entered, with no middleman domain.

Making codes last

• Use static codes for anything meant to be permanent.
• Point to a stable URL you own so you can update the page behind it without changing the code.
• Keep the destination alive — renew the domain, don't delete the page.
• Print and protect properly — durable materials, good contrast, adequate size and margin.
