When you create a QR code, there are two fundamental types: static and dynamic. Understanding the difference is one of the most important things to know before you invest in printing QR codes on physical materials.
What is a Static QR Code?
A static QR code permanently encodes its data — a URL, text, contact information — directly into the pattern of black and white squares. Once created, the encoded data cannot be changed. If you print a static QR code pointing to yourwebsite.com/old-page and that page changes, the QR code becomes useless. You would need to create a new QR code and reprint all your materials.
Best for: One-time use, personal projects, content that will never change (a vCard, a WiFi password, a single-use URL).
What is a Dynamic QR Code?
A dynamic QR code encodes a short redirect URL (e.g., qrstats.in/r/abc123). When scanned, this short URL redirects to your actual destination. Crucially, you can change the destination at any time from your dashboard — without changing the QR code itself. The physical QR code printed on your poster or packaging always redirects wherever you point it.
Best for: Business use, marketing campaigns, any situation where you might want to update the destination or track scan data.
Comparison: Static vs Dynamic QR Codes
| Feature | Static | Dynamic |
|---|---|---|
| Editable after creation | No | Yes |
| Scan tracking / analytics | No | Yes |
| Requires account | No | Yes (free) |
| Works offline | Yes (for vCard/text/WiFi) | No (requires redirect) |
| Suitable for print runs | Risky | Yes — update link, not code |
| Data density | Higher (more complex pattern) | Lower (short URL only) |
When to Choose Static
- Personal use where the data is permanent (sharing your personal vCard)
- WiFi sharing (your password rarely changes)
- Offline use cases where internet is not guaranteed
- Quick one-off generation with no tracking needed
When to Choose Dynamic
- Business marketing materials — brochures, packaging, signs
- Restaurant menus that change seasonally
- Event QR codes that link to information that changes
- Any situation where you want to measure performance
- Large print runs where reprinting is expensive
How to Create Both Types on QR Stats
Without an account: visit QR Stats and create a QR code — you get a static code by default.
With a free account: log in and create a QR code — it is automatically created as a dynamic, trackable QR code.
