Not all QR codes work the same way. When you generate a QR code, you're choosing between two fundamentally different approaches: static and dynamic. The right choice depends on whether you need to change the destination later, track scan analytics, or simply keep things simple and free. Here's everything you need to know to make the right call.
What is a static QR code?
A static QR code has its destination encoded directly into the pattern of the code itself. When someone scans it, their phone reads the URL or data directly from the image — no server involved. Because all the information is baked in, a static QR code works forever without any third-party service, and will still function even if the company that generated it shuts down.
The trade-off is permanence. Once printed, a static QR code cannot be changed. If the URL it points to changes — say, your website moves or the linked page is deleted — the code becomes broken. There is also no scan tracking; you won't know how many people scanned it, when, or where.
What is a dynamic QR code?
A dynamic QR code encodes a short redirect URL managed by a third-party service. When someone scans the code, they are first sent to that redirect service, which then forwards them to the actual destination. Because the redirect is controlled by the service, you can change the final destination at any time — without changing or reprinting the QR code itself.
Dynamic codes also unlock analytics: the redirect service can log every scan, recording timestamps, device types, and sometimes geographic location. This is valuable for marketing campaigns where measuring reach matters. The downside is ongoing dependency on the service — if it goes offline or your subscription lapses, the code stops working.
Comparison
| Feature | Static | Dynamic |
|---|---|---|
| Cost | Free | Usually requires a subscription |
| Change destination | No | Yes, any time |
| Scan tracking | No | Yes |
| Works without internet | Yes (data encoded directly) | Redirect requires internet |
| Complexity | Simple — no account needed | Requires a third-party service |
| Best for | Permanent links, personal use | Marketing campaigns, A/B testing |
When to use static
Static QR codes are the right choice for the vast majority of use cases, especially when the destination is unlikely to change:
- Your business website or homepage URL
- A WiFi password (encoded directly, no URL needed)
- A contact card (vCard data)
- Your social media profile links
- Any personal or small-business use where you don't need analytics
Static codes are simpler, free to generate, and will work indefinitely without any ongoing service dependency.
When to use dynamic
Dynamic QR codes earn their subscription cost in specific scenarios:
- Marketing campaigns where the landing page URL may change after materials are printed.
- Seasonal promotions — reuse the same printed code to point to a Christmas offer in December and a summer sale in July.
- A/B testing — switch destinations to test which landing page converts better from the same physical placement.
- Tracking ROI on print advertising by measuring how many people scanned codes in a specific flyer, poster, or publication.
