Do QR Codes Expire? (The Short Answer: No)

QR codes do not expire. A QR code you generate today will work exactly the same way in 5, 10, or 20 years — as long as the link it points to (or the information it contains) still exists.

Why QR codes don't have an expiration date

A QR code is just an image. It's a static picture of encoded data, created once and never changed. There's no expiration timer, no server keeping track of its age, no automatic deletion. When someone scans it, the data is decoded from the image itself — no clock is involved.

Think of it like a barcode on a product. The barcode doesn't expire because it's just a visual representation of a number. Neither does a QR code expire because it's just a visual representation of data.

When do QR codes actually stop working?

A QR code stops being useful when the content it links to disappears or changes. For example:

• A QR code linking to a website stops working when that website is taken down or moved to a different URL.
• A QR code encoding a phone number still works unless you stop using that phone number.
• A QR code with WiFi credentials still works as long as your WiFi network and password remain the same.
• A QR code linking to a temporary event still works even after the event happens — it just links to outdated information.

Static QR codes (permanent) vs. Dynamic QR codes (changeable)

There are two types of QR codes, and this distinction matters:

<strong>Static QR codes</strong> (what PXLA generates) are fixed images with data encoded directly into them. They never change and can be used indefinitely. When you generate a static QR code linking to a website, that link is baked into the image. If you change your website's URL, the old QR code will link to a dead page.

<strong>Dynamic QR codes</strong> are generated by a service that maintains a short, memorable URL. You scan the code, and it redirects through a server that can be updated. For example, you could generate a dynamic code today linking to page-A, then change it next week to point to page-B without regenerating the image. However, dynamic QR codes depend on that service staying online.

For most uses, static codes are fine and actually more reliable — they don't depend on an external service.

How long can you rely on a QR code?

As long as the underlying content exists:

• A QR code linking to your website works forever if your website stays online.
• A QR code with your WiFi password works forever if that password doesn't change.
• A QR code encoding a phone number works forever as long as you keep that phone number.
• A QR code in a printed catalog works forever as long as the page it links to still exists (or you redirect it).

Best practices for long-lasting QR codes

If you want your QR codes to work for years:

• Link to stable URLs that won't move or change.
• For printed materials (business cards, packaging), link to your homepage or a permanent landing page — not a promotional campaign that expires.
• If you need to change where a code points, use redirects (301 redirects for websites) rather than moving content to a new URL.
• Test your code regularly, especially if it's printed on materials in wide circulation.
