Do QR Codes Expire?

What actually makes a QR code stop working

Why static QR codes never expire

With a static code, your URL, Wi-Fi details, or contact card are encoded straight into the pattern. Nothing sits between the scanner and your data — no redirect, no account, no company. So it keeps working for as long as the destination exists, offline and indefinitely. The only way a static code "stops working" is if the thing it points to goes away (for example, you take the linked website down).

Every code you export from the free Qrogo generator is static and permanent — no login, no expiry, no strings attached.

Why dynamic QR codes can stop working

A dynamic code encodes a short redirect link owned by the provider. When someone scans it, they hit that link first and get forwarded to your real destination. That redirect is useful — you can change the destination after printing and see scan analytics — but it means the code depends on a third party. A dynamic code dies if:

• The provider shuts the redirect off (trial ended, plan downgraded, unpaid invoice).
• The company goes out of business or sunsets the product.
• You close your account.

When that happens, the printed code doesn't just lose analytics — it becomes a dead link. (More on that in what happens if the company shuts down.)

The "free" catch to watch for

This is where people get burned. Many tools advertise "free QR codes," but quietly issue dynamic codes on a trial. The code scans fine while you're testing it — then stops redirecting a couple of weeks later unless you subscribe. If you've already printed it on a thousand flyers, that's an expensive lesson. Always check whether a "free" code is static (permanent) or dynamic (tied to the service).

Does the code from <your tool> expire? How to check in 30 seconds

People usually arrive at this question about one specific tool — QRCG, QR Code Gecko, GetQR, the code a Shopify app generated. Rather than trust a marketing page, you can answer it yourself for any provider, because it always comes down to the same two questions.

1. What URL is actually in the code? Scan it with any app that shows the link before opening. If you see your own destination, the code is static and nothing can switch it off. If you see a short link on the provider's domain, it is dynamic and depends on them.
2. If it's dynamic, what happens when you stop paying? Search their terms or pricing page for "expire", "trial" and "downgrade". The answer you want is what becomes of an existing printed code — some providers keep redirecting after a downgrade, some stop.

Question one is the decisive one and takes seconds. A static code cannot be expired by anybody, including the tool that made it, because there is nothing in the middle to turn off. That is also why the answer to "does it last forever?" is a property of the code type, not of the brand that generated it.

Worth checking before a reprint rather than after: if the code is dynamic and the provider disappears, the printed pattern cannot be corrected (see what happens if the company shuts down).

How to make a QR code that never expires

• Use a static code for anything permanent — a Wi-Fi password, a vCard, a fixed website URL.
• Keep the destination URL live and on a domain you control.
• Print with high contrast and a clear margin so it stays scannable for years.
• If you genuinely need to re-target the code later or want analytics, use a dynamic code — just understand the trade-off, and pick a provider whose codes keep working.

Do QR codes wear out physically?

The data won't, but the print can. Scanning depends on a camera telling dark modules from light ones, so faded ink, sun bleaching, low contrast, glare from lamination, or a torn corner can all stop a code reading. QR codes include error correction that tolerates some damage — a code with a logo forces the highest level — but there's no substitute for a clean, high-contrast print.
