Do QR Codes Expire? (And How to Make Permanent Ones)
The short answer: Static QR codes never expire, but dynamic QR codes can expireif your subscription ends or the service shuts down. This comprehensive guide explains the difference and how to ensure your QR codes work forever.
Quick Answer
Static QR Codes: Never expire (permanent)
Dynamic QR Codes: Work as long as your subscription is active
Physical Damage: Can make codes unscannable over time
Best Practice: Use static for permanent items, dynamic for campaigns
Understanding QR Code Types
To understand QR code expiration, you need to know the two types of QR codes:
Static QR Codes
Data is embedded directly in the QR code. The code never expires and works forever.
How it works:
QR Code → Contains "https://example.com"- ✓ Works forever (no expiration)
- ✓ No subscription required
- ✓ No analytics tracking
- ✓ Cannot change destination
Dynamic QR Codes
Code contains a redirect URL. The destination can be changed. Requires active subscription.
How it works:
QR Code → "https://qr.io/abc123"Redirect → "https://your-website.com"- ✓ Track scans and analytics
- ✓ Change destination anytime
- ✓ A/B testing capability
- ⚠️ Requires active subscription
When Do QR Codes Stop Working?
1. Your Subscription Expires (Dynamic Codes Only)
If you're using a QR code service with dynamic codes and your subscription expires, your codes may stop working.
What happens:
- • Code redirects to "subscription expired" page
- • Analytics stop tracking
- • You can't update the destination
- • Some services delete codes after 30-90 days
2. The Service Shuts Down
If the QR code service you used goes out of business, all dynamic codes stop working immediately.
Real example:
In 2021, several free QR code services shut down unexpectedly. Thousands of printed QR codes on menus, business cards, and marketing materials became useless overnight.
3. The Destination Link Dies
Even permanent static QR codes stop working if the URL they point to is deleted or changed.
Common causes:
- • Website redesign changes URLs
- • Domain expires and isn't renewed
- • Page gets deleted or moved
- • Company goes out of business
4. Physical Degradation
The QR code itself can become unscannable due to physical damage or environmental factors.
Degradation factors:
- • UV exposure fades printed codes
- • Water damage smears ink
- • Scratches and wear from handling
- • Low-quality paper deteriorates
How to Create Permanent QR Codes
Method 1: Use Static QR Codes (100% Permanent)
For truly permanent QR codes that will work forever, use static QR codes:
- Use a free generator: Many tools create static QR codes for free with no expiration
- Encode the final URL directly: Make sure it's the exact page you want, not a redirect
- Download and save: Save the QR code image file (you own it forever)
- Print it: Once printed, it will work indefinitely
Best for:
- • Business cards
- • Gravestones/memorials
- • Book publications
- • Product packaging with stable URLs
- • Any situation where the URL will never change
Method 2: Use Dynamic Codes with Reliable Service
If you need tracking and flexibility, use dynamic codes from a reliable service:
- Choose an established service: Look for companies that have been around for 5+ years
- Check data export policies: Ensure you can export your data if you leave
- Read the terms: Understand what happens if your subscription expires
- Consider annual plans: Less chance of accidental expiration
- Set payment reminders: Never let your subscription lapse unexpectedly
Method 3: Self-Hosted Solution (Advanced)
For maximum control, host your own redirect system:
- Buy your own domain: e.g., go.yourbrand.com
- Create short redirect URLs: go.yourbrand.com/menu
- Generate static QR codes: These point to YOUR domain
- You control the redirects: Change destination without reprinting
Benefit: You're not dependent on any service. As long as you keep your domain, the QR codes work forever. Even better than traditional dynamic codes.
Static vs. Dynamic: Which Should You Use?
| Feature | Static QR Code | Dynamic QR Code |
|---|---|---|
| Expiration | Never (permanent) | Subscription-based |
| Cost | Free | $5-50/month |
| Analytics | None | Full tracking |
| Editable | No (fixed URL) | Yes (anytime) |
| QR Code Size | Larger (more data) | Smaller (short URL) |
| Reliability | 100% (self-contained) | Depends on service |
| Best For | Permanent items | Marketing campaigns |
Real-World Use Cases
Use Static QR Codes For:
- Business Cards: Your contact info or website won't change frequently
- Book Covers: Additional resources or author website
- Gravestones/Memorials: Links to memorial pages that should last forever
- WiFi Access: Network credentials encoded directly
- Product Manuals: PDF instruction manuals with stable URLs
- Museum Exhibits: Permanent displays with educational content
Use Dynamic QR Codes For:
- Restaurant Menus: Update prices and items without reprinting
- Marketing Campaigns: Track performance and adjust on the fly
- Event Promotions: Update details as they change
- Product Packaging: Run seasonal campaigns on the same box
- Retail Displays: Update sale information without replacing signage
- Real Estate Signs: Update listing details or add virtual tours
Protecting Your Investment
If You're Using Dynamic Codes:
- 1Set up payment alerts: Get notified 30 days before renewal to avoid accidental expiration
- 2Use annual billing: Less chance of forgetting to renew
- 3Keep a backup: Document all your QR codes and their destinations
- 4Choose reliable services: Research the company's track record and reviews
- 5Export your data regularly: Keep CSV files of all codes and destinations
What Happens When QR Codes Expire?
When a dynamic QR code "expires," scanning it typically results in one of these experiences:
Worst Case
"Page not found" error. User has no idea what the code was supposed to do.
Common Case
"QR code expired" message with option to renew subscription (if you're the owner).
Best Case
Grace period where codes work for 30-90 days after expiration (service-dependent).
FAQ
Can I reactivate an expired QR code?
Yes, if you're using dynamic codes. Simply renew your subscription and the codes start working again. The QR code image itself doesn't change, so printed materials remain valid.
How long do free QR codes last?
Static QR codes from free generators last forever. Dynamic free QR codes usually have limits (e.g., expire after 30 days, limited scans, or display ads).
Can I convert a dynamic QR code to static?
No. Once created, a QR code's type is permanent. However, you can create a new static code pointing to the same destination and replace the old one.
Do static QR codes have unlimited scans?
Yes! Static QR codes can be scanned unlimited times. There's no tracking or server involved, so there's no way to limit or count scans.
What if my website URL changes?
With static codes, you'd need to reprint. With dynamic codes, just update the destination in your dashboard. This is the main advantage of dynamic codes.
Conclusion
Static QR codes never expire and are perfect for permanent applications. Dynamic QR codes require active subscriptions but offer tracking and flexibility. Choose based on your needs, and if you're investing in printed materials, always consider the long-term implications of your QR code strategy.
Key Takeaways:
- ✓ Static codes = permanent, dynamic codes = subscription-based
- ✓ Use static for business cards, books, memorials
