Do QR Codes Expire? Here's the Honest Answer
The short answer: static QR codes never expire. Dynamic QR codes can expire — but only if the service that hosts them stops working or your subscription lapses.
This matters enormously if you're printing QR codes on business cards, menus, packaging, or signage. Here's exactly what determines whether a QR code stops working, what happened when several free QR code services shut down, and how to protect yourself.
Static QR Codes: They Last Forever
A static QR code encodes data directly in the pattern — a URL, a phone number, a WiFi password, a vCard. When you scan it, your phone reads the data from the pattern itself. There is no server, no redirect, no third-party service involved.
This means a static QR code cannot expire. As long as the destination URL still works (the website it links to is still live), the QR code will function indefinitely. A static QR code printed in 2015 scans exactly the same as one printed today.
The downside: you cannot change the destination once it's printed. If the URL changes, the QR code is broken — and you need to reprint. This is why static codes are best only for permanent data like WiFi credentials, fixed contact info, or URLs that will never change.
Key Takeaways
- Static codes are permanently tied to the original URL — if the website moves, the QR breaks
- A static QR code with a dead-link destination still "works" technically — it just leads nowhere
- Use static QR codes only for data that will never change
Dynamic QR Codes: It Depends on the Platform
A dynamic QR code encodes a short redirect URL managed by a QR code platform (like QR Base). When scanned, your phone visits the redirect URL, which then sends the browser to the real destination.
This means the QR code pattern never changes — but the destination can be updated from a dashboard. The trade-off: the QR code depends on the redirect service being active.
Dynamic QR codes can stop working in these scenarios:
- Your subscription expires — most paid QR platforms disable redirects when subscriptions lapse. Always check the platform's policy.
- The platform shuts down — several free QR code services closed in 2019–2022, breaking millions of printed codes. Coupon Follow's free QR service closed in 2019. Scanova's free dynamic tier was discontinued. QR Stuff changed its free policies.
- Scan limits are hit — some free tiers cap total scans. After the limit, the QR returns an error.
QR Base's policy: codes remain active for the duration of your subscription. The free plan supports static codes with no expiration within plan limits. See pricing details →
Key Takeaways
- Always read the terms of a QR platform before printing at scale
- Check if free tiers expire codes, cap scans, or add third-party branding
- QR Base free plan codes don't expire within plan limits
What Happened When Free QR Services Shut Down
Between 2019 and 2022, multiple free QR code services quietly retired their free tiers or shut down entirely. Businesses that had printed dynamic QR codes with these services discovered their codes no longer worked — sometimes months after the fact, when they started receiving customer complaints.
The impact was most severe for:
- Restaurant menus with QR codes printed on thousands of table tents
- Product packaging with QR codes on large print runs
- Real estate signs and marketing materials
- Business cards distributed at conferences
The lesson: free dynamic QR codes are a risk for any material that's printed in volume and expected to work for more than a few months. Compare free vs paid QR code generators →
Key Takeaways
- Never use a free dynamic QR service for professional print materials
- Check the platform's track record and funding before relying on it long-term
- Keep a record of which platform generated each QR code for future auditing
How to Make Your QR Codes Last
Best practices to ensure your QR codes keep working:
- Use a paid dynamic QR service with a clear uptime policy. Read the terms: what happens to your codes if you cancel? QR Base keeps your redirect infrastructure active for your subscription duration.
- Use static QR codes for truly permanent data. WiFi passwords, personal contact info, and fixed URLs that will never change are fine as static.
- Audit QR codes on important materials annually. Scan all printed QR codes once a year to catch broken links before your customers do.
- Download SVG, not PNG. If you ever need to regenerate a QR code, having the vector SVG means the visual matches your original design exactly without rescaling artifacts.
- Avoid obscure free tools. Stick to established platforms with business track records. If a service has been running for 5+ years and has a paid tier, it's less likely to disappear.
Key Takeaways
- Annual QR code audit: scan every printed code to verify it still works
- SVG files can be reprinted at any size if you need to update a design
- Test QR codes on both iPhone and Android after any URL change
Frequently Asked Questions
It depends on the tool. Static QR codes from any tool never expire (the data is in the pattern). Free dynamic QR codes may expire when scan limits are hit, when subscriptions lapse, or if the platform shuts down. Always check the terms before using a free dynamic QR service for printed materials.
A static QR code lasts forever as long as the URL it links to still works. A dynamic QR code lasts as long as the redirect service is active and your account is in good standing.
Your dynamic QR codes stop working — the redirect URL no longer resolves. This is exactly what happened to thousands of businesses when free QR services closed between 2019 and 2022. Use a stable paid platform for any QR on print materials.
Yes, if it's a dynamic QR code and the hosting service goes offline, shuts down, or your account lapses. The physical code itself doesn't change — but the server-side redirect stops functioning.
QR Base keeps your codes active for the duration of your subscription. Free plan codes remain active within plan limits. We do not impose arbitrary expiration dates or scan caps on paid plans.
Simply scan it with your phone camera. If it redirects correctly to the intended destination, it's working. Scan on both iPhone and Android for a complete check. Do this annually for all printed QR codes.
A dynamic QR code from a reputable paid platform is the safest choice — it gives you editability (so you can update the destination without reprinting) plus the stability of a paid, maintained service.
