This is one of the most common questions about QR codes — and the answer is "it depends." The QR code image itself never expires. But whether it still works when scanned depends on what's behind it.
Static QR Codes: Never Expire
A static QR code encodes data directly in the image — a URL, phone number, WiFi credentials, or text. The data is baked into the pattern of dots. There's no server, no subscription, no external dependency.
A static QR code created today will work identically 50 years from now, as long as QR scanning technology still exists (and there's no reason it wouldn't — it's an open standard).
The QR code itself can't expire because all the information is self-contained.
But the content can become invalid:
- A URL QR code still works, but the website behind the URL might shut down → the QR scans, but the link is dead
- A WiFi QR code works, but you changed the password → the QR scans, but the connection fails
- A phone number QR works, but the number was disconnected → the QR scans, but the call doesn't go through
In these cases, the QR code didn't expire — the content it points to changed. The QR itself is fine.
Dynamic QR Codes: Depends on the Service
Dynamic QR codes encode a short redirect link (like qree.app/abc123) rather than your actual destination. When scanned, the request goes to the QR service's server, which redirects to your destination URL.
Dynamic QR codes can "expire" in several ways:
The QR platform shuts down. If the company hosting your redirects goes out of business, the short links stop working. The QR code scans fine, but the redirect server doesn't exist anymore. This is the biggest risk with dynamic QR codes.
Your subscription expires. Many QR platforms require a paid subscription for dynamic codes. If you stop paying, some services deactivate your redirects. Your QR codes suddenly lead to error pages.
Scan limits reached. Some free plans limit the number of scans per QR code. After the limit, the code stops redirecting. This is common on platforms with aggressive free-tier restrictions.
You delete the QR code. If you delete a QR code from your dashboard, the redirect stops working. The physical QR still scans, but there's nothing to redirect to.
You deactivate it intentionally. Some platforms let you turn off specific QR codes. Useful when a campaign ends, but it means the QR stops working.
How to Make Sure Your QR Codes Keep Working
For static QR codes
Use stable URLs. If you create a QR code for a webpage, use a URL that's under your control and unlikely to change. A personal domain is more reliable than a third-party platform URL that might restructure.
Use permanent content. WiFi passwords, phone numbers, and email addresses should be things that won't change anytime soon.
For dynamic QR codes
Choose a reliable platform. Use a QR service that's likely to be around long-term. Consider platforms with a clear business model, active development, and good reputation.
Keep your account active. If you're on a paid plan, keep paying. If you're on a free plan, check the terms — does the free tier have scan limits or expiration dates?
Monitor your QR codes. Check your dashboard periodically to make sure all redirects are active and pointing to the right destinations.
Export your data. Keep a spreadsheet documenting all your QR codes: short code, destination URL, where the physical QR is placed, and when it was created. If you ever need to migrate to a different platform, this documentation is invaluable.
Have a migration plan. If your QR platform shuts down and you have QR codes printed on permanent materials (packaging, signage, engraved plaques), you'll need to either reprint or find a way to redirect. Some platforms allow custom domains, which means you could point the domain to a new service if the original shuts down.
Free vs Paid: Expiration Risks
Free QR code plans often come with strings:
- Scan limits. "Free for up to 100 scans per month." After that, the code redirects to a paywall or stops working.
- Time limits. "Free for 14 days." After the trial, your codes go inactive.
- Feature limits. The code works, but analytics or editing are disabled after downgrade.
- Branding requirements. Free codes may show the platform's branding on the redirect page.
Read the fine print before creating QR codes you plan to print on permanent materials. A QR code on a product package that dies after 100 scans is worse than no QR code at all.
At qree.app, all QR codes during Early Access are fully free with no scan limits, no time limits, and no expiration.
What About QR Codes on Old Products?
You might encounter QR codes on old products, marketing materials, or signs that no longer work. Common reasons:
- The company changed their website URL
- The QR platform the company used shut down
- The company went out of business
- The QR pointed to a campaign page that was taken down
This is normal and expected. QR codes on temporary materials (flyers, event posters) are meant to have a limited useful life. QR codes on permanent materials (product packaging, building signage) should use dynamic codes from reliable platforms to maximize longevity.
Summary
| QR Type | Does It Expire? | What Can Go Wrong |
|---|---|---|
| Static QR | Never | The content behind the URL can change or disappear |
| Dynamic QR | Depends on platform | Platform shutdown, subscription expiry, scan limits, account deletion |
| Any QR image | Never physically | The printed/digital image itself is permanent |
Create Long-Lasting QR Codes
At qree.app, dynamic QR codes have no scan limits and no time-based expiration. Create codes that work for as long as you need them.
