How Long Does a QR Code Last?
The lifespan of a QR code depends on whether it’s a static or a dynamic QR code with editable features
Static QR codes are fixed and made for a URL and information that will not change, so they do not expire and are permanent.
Dynamic QR codes, on the other hand, redirect users to a short URL and can be updated, and in certain cases can expire or become invalid.
Here’s a quick breakdown of the key differences between each type, including what they work best for, and how QR code data is encoded and stored:
|
Static QR codes |
Dynamic QR codes |
|---|---|
| Store data directly | Store a short URL that redirects to the final destination |
| Cannot be changed once generated | You can update the URL at any time |
| No tracking or analytics | Track scans, location, devices, and more |
| Best for permanent info like emails or contact details | Best for marketing, campaigns, or content you may update |
What Makes a QR Code Inactive?
When a QR code becomes inactive, it’s not because the code has actually expired. In most cases, the problem lies with the destination URL or how the code is managed.
A QR code is simply a visual container for data: its pattern of black‑and‑white (or color) modules encodes information through a specific QR code generation process that uses data encoding and error correction.
As long as the structure of the QR code symbol is still readable, and the linked content remains accessible, the code itself does not “expire.”
Static QR codes work unless the link or code breaks
A static QR code will not expire or become inactive unless the destination it links to is unavailable. This can happen:
- If your URL changes
- If your web page is deleted
- If your entire site goes offline
Physical damage can also affect a QR code’s performance. If a code on printed materials, such as posters, gets ripped or scratched, smartphone cameras might have trouble scanning it.
Dynamic QR codes require ongoing maintenance
A dynamic QR code does not store the destination URL directly. Instead, it uses your QR platform to manage where the code directs users.
This setup allows you to change the destination at any time without reprinting. However, the code can stop working if certain conditions are not met. For example:
- If your account is inactive
- If your subscription ends
Scan limits are another factor. Some QR code platforms cap the number of scans per month, which can cause dynamic codes to stop working once the limit is reached.
With QRNow, every PRO plan offers dynamic codes with unlimited scans. This means your codes stay fully active no matter how many people scan them.
Examples of Permanent or Long-Term Uses of QR Codes for Businesses
Dynamic codes offer you more in terms of long-term use and flexibility.
However, if you want to use a static code, there are some uses for them as well. Here are some examples to give you an idea of what to use your QR code for:
Best uses for long-term static QR codes
You can take advantage of creating a static code when the content is permanent and unlikely to change, such as in.
- Business cards: Link to your LinkedIn profile or digital vCard, if you don’t expect to change it.
- Printed manuals: Use a PDF QR code to connect to a file, such as a manual.
- Storefront signage: Show store hours or a direct link to a non-changing contact page.
Best uses for long-term dynamic QR codes
“Do dynamic QR codes expire?”, you might be wondering. These types offer you much more even if they expire at some point. You should use them when the content might change, or you want more control. Here are some examples:
- Videos and pages: Link to instructional videos or registration pages that may be updated later.
- Campaigns: Redirect to seasonal offers, updated promotions, or landing pages that change over time.
- Event codes: Create dynamic event QR codes and update agendas when needed, locations, or contact info after printing.

Top Tips for Making Sure Your Codes Work Long-Term
There are a number of things you can do to help make sure your code works long-term. To avoid broken links or expired codes, follow these tips:
Choose the right type of code
If you want to use a static QR code, generate one for links that won’t change, like a permanent contact page.
For other uses, take advantage of dynamic QR codes for any links or material that will need content changes or if you want tracking features.
Keep your dynamic codes active
Most dynamic QR codes depend on a subscription. If your subscription ends, the code may stop working. Make sure your plan stays active.
Check linked content regularly
It’s important to make certain the information, such as a URL or file, in your QR code is up-to-date.
Even static codes can become invalid if the destination page is deleted or moved. Set a reminder to check the links every few months.
Use stable URLs
If you decide to create a static code, it’s critical that you choose a URL that won’t change. Avoid linking to pages that you may need to update or delete.
You can create a static code for free, but if you need to make an update, you will need to create a brand-new code.
FAQs About Keeping QR Codes Active
Do QR codes lose quality when resized?
Toggle faqs
QR codes remain readable if their structure is clear. You can scale a QR code up or down, but shrinking or enlarging it too much can make the pattern unreadable. Make sure to export in high-resolution PNG or vector formats to avoid blurry or compressed edges.
Can QR codes handle large amounts of data?
Toggle faqs
Yes. The data capacity of QR codes is high. However, adding more information makes the pattern denser and can make scanning more difficult. For very long URLs or complex content, a dynamic QR code is usually better, since it only encodes a short redirect URL.
What can I do if a QR code becomes inactive?
Toggle faqs
First, confirm the destination URL is valid and your dynamic QR subscription is active. Updating the link or renewing the plan usually restores functionality. In some cases, you might need to reactivate or reprint the code.
Is it possible to extend the lifespan of a QR code?
Toggle faqs
You can maintain a QR code’s long-term reliability by using stable URLs that will not be moved or deleted. It’s also important to protect printed codes from physical damage or, if possible, use a dynamic QR service with unlimited scans.
