Do QR Codes Expire? The Definitive Answer

You've just printed 5,000 flyers with a QR code linking to your website. You're about to launch a product with a QR code on the label. Then, a worrying thought crosses your mind: Will this QR code stop working in a year? Do QR codes expire?

This is one of the most frequently asked questions about QR codes, and the answer is crucial for anyone using them. The good news is, the answer is simple, but it depends entirely on the type of QR code you create.

The Short Answer

• Static QR codes do NOT expire.
• Dynamic QR codes CAN expire.

Let's break down why.

Why Static QR Codes are Forever

A static QR code, like the ones you can create for free on QRFastGen, has the destination data encoded directly into its pattern. The URL, text, or Wi-Fi information is a permanent part of the code's structure.

Think of it like a sentence printed in a book. As long as the book exists, the sentence can be read. In the same way, as long as the QR code image exists, it can be scanned.

A static QR code will only "stop working" for two reasons:

• The destination is broken. If your QR code links to a webpage, and you later delete that page, the QR code will still scan, but it will lead to a 404 error page. The code itself works perfectly; the destination is the problem.
• The image is damaged. If the printed QR code is significantly scratched or faded, a phone's camera may not be able to read it.

But the code itself has no expiration date. It will work for 1 year, 5 years, or 20 years from now.

The Deal with Dynamic QR Codes

Dynamic QR codes are different. They work by encoding a short, intermediate URL into the code. When you scan it, this short URL redirects the user to the final destination URL that you've set.

This system is what allows the final destination to be edited and tracked. However, the company that provides the dynamic QR code service has to host and maintain that short URL. This service costs money, which is why dynamic QR codes are usually part of a paid subscription.

A dynamic QR code will expire if you stop paying the subscription fee or if the company goes out of business.

Which Type Should You Use?

The choice depends on your needs:

• Use a STATIC QR code for: Any information that is permanent. This includes your main website link, a vCard digital business card, Wi-Fi access, or a link to your app in an app store. Since the code is permanent and free, it's the safest choice for long-term use.
• Use a DYNAMIC QR code for: Short-term marketing campaigns, temporary promotions, or any situation where you need to track scan analytics or might need to change the destination link later.

Conclusion: Create with Confidence

For the vast majority of everyday uses, a static QR code is the perfect tool. It's reliable, permanent, and completely free. You can create one on your own and have peace of mind knowing it will work for your users forever, without any hidden fees or expiration dates.Create your permanent, non-expiring static QR code at QR Fast Gen today!
