QR codes have now become a staple in our digital world and they offer a fast and easy way to access websites, information, and services with your smartphone.
It is assumed that by 2027, there will be a 70% overall rise in QR Code generation, equivalent to nearly 800,000 QR Codes.
However, sometimes, you can see your QR code not working properly, and you experience failure while scanning QR codes. Do you know the reason behind it?
Let us understand the top 10 reasons why your QR code might not be working and how you can solve those issues.
Ensure your QR codes are high-resolution and have a clear contrast with their background. Always add sufficient white space around the code to avoid confusion with surrounding elements. Using a reliable QR code generator, like the WhatsApp QR code generator, can help prevent common issues and ensure seamless scanning.
Top 10 Reasons Why Your QR Code Is Not Working
QR codes are generally reliable, but several factors can impede their functionality. Here are the top reasons why you might get an error when scanning a QR:
1. The Code Is Too Small Or Too Blurry
One of the most common issues is the size and clarity of the QR code. If the code is too small, most smartphone cameras will struggle to read it.
Similarly, if there are blurry QR codes, perhaps due to low-resolution printing or poor image quality, scanning errors are likely to occur.
Solution: To ensure optimal readability, print your QR code in high resolution and avoid making it too small. Generate your multiple QR codes design in PNG or SVG and adjust the resolution.
2. The Code Is Dirty Or Damaged
A dirty or broken QR code can obstruct the pattern, making it unreadable. Whether printed on paper or displayed on a screen, QR codes need to be clear and intact.
Even if you laminate or cover paper with plastic, it will certainly wear out over time if left outside. For example, water can seep into the paper if it’s laminated, along with plastic fades, peels, and cracks under different circumstances.
Solution: Regularly check and clean printed codes and ensure that digital displays are free from cracks or damage.
3. The Image is Too Dark or Has Low Contrast
For a QR code to be easily scanned, there must be a clear contrast between the code and its background. A QR code that is too dark or set against a low-contrast background can be difficult for cameras to detect.
The background material color should not be the same as the QR code. This makes it tough for a scanner to distinguish between where the design ends and the QR Code begins.
Solution: Always use a background with a dark code, and avoid colors that blend. Seek professional help to create QR codes of high standards.
4. The Code is Too Close to Other Objects or Text
QR codes are meant to be easily recognized by electronic devices. The three dots in the upper left corners are there to help cameras align the image so they can scan it properly from different angles.
Surrounding your QR code with other objects or text can confuse the scanner, leading to errors. Extra visual clutter may have an impact on readability as well.
Solution: Generate QR code in such a way that there is sufficient white space around the QR code to allow the scanner to easily distinguish it from other elements. This “quiet zone” is critical for accurate scanning.

Copying a URL from a browser or document can sometimes include extra characters or spaces, leading to an invalid QR code. An incorrect link address embedded in the QR code will lead users to a dead end.
Additionally, if a QR code links to a page that has been moved or deleted, the code will no longer work.
Solution: It is better to test the URL thoroughly by scanning it with multiple devices to ensure it directs to the correct page.
6. The URL’s Redirect is Going to the Wrong Place
People frequently utilize URL redirection to keep the QR message current and dynamic. With redirects, you may configure the original URL to automatically transfer customers to a new URL when they scan your code.
If the URL embedded in your QR code redirects to an unintended location, it can cause confusion and frustration. Misconfigured redirects are a common reason why a QR code might appear to work but ultimately fail.
Solution: Always verify your links and domain name system (DNS) settings.
7. The Website Itself Isn’t Loading
As you are certainly aware, this occurs frequently. It’s easy to assume there’s a problem with the link when the server could simply be down. A QR code is only as effective as the website it leads to. If the website is down or experiencing loading issues, the QR code system will not work.
Problems with your domain registration, DNS configuration, or domain expiration can prevent your website from loading.
Solution: Invest in a reputable hosting provider known for reliability and speed. Look for providers that have excellent customer support and a robust infrastructure.
8. Your Website Doesn’t Work on Mobile
Since most QR codes are scanned using smartphones, the linked website must be mobile-friendly. Websites that are not optimized for mobile devices can lead to a poor user experience or fail to load correctly.
Mobile users are more likely to abandon a site that isn’t user-friendly. If your goal is to drive conversions through free QR codes, a mobile-optimized website is critical to achieve this.
Solution: Optimize your website for speed. Compress images, leverage browser caching, and minimize code to ensure quick loading times. Mobile users are particularly sensitive to delays, so aim for load times of three seconds or less.

Sometimes, the issue lies with the device scanning the QR code. This is a possibility as well. Phones were not able to scan QR codes without special software until a few years ago. Thus, older models may require a particular program to read the codes.
Newer phones have mostly eliminated the need for additional software, such as specialist QR code reader apps. All you have to do is open the camera and point it at the code; it will scan. However, this approach is not always effective.
Solution: Keep the camera lens clean so that it can function properly. In cases of persistent issues, try using a different device to scan the QR code.
10. Your QR Code Generator Isn’t Working Properly
Not all QR code generators are created equal. Some may produce codes that are faulty or difficult to scan. As a result, the QR code won’t scan properly.
The functionality of your QR codes heavily depends on the quality of the QR code generator you use. If the generator is flawed or unreliable, it can lead to QR codes that don’t work as expected.
Solution: Use generated QR codes from reputable providers with positive user reviews. Look for generators that have been recommended by industry experts or have high ratings from users. For WhatsApp QR codes specifically, you can try ControlHippo’s WhatsApp QR code generator to quickly connect with your audience.
Bottom Line
QR codes are a powerful tool for connecting the physical and digital worlds, but they must be created and maintained correctly to function properly.
By understanding and addressing why is the QR code not working, you can ensure that your QR codes are always ready for flawless scanning.
Regular testing and maintenance, along with the use of reliable QR code generators, can significantly reduce the chances of experiencing difficulties.
Frequently Asked Questions
QR code test is so simple. Use multiple QR code scanning app devices to scan the code. Ensure it directs you to the correct URL and functions as intended. Regular testing, especially before widespread distribution, can prevent many common issues.
Your QR code may not be working on your iPhone due to several reasons. Enable scan QR codes in the camera settings so that you are in photo mode. Check if the camera lens is clean and the QR code is well-lit. If issues persist, try force-closing the camera app, restarting your iPhone, or updating your iPhone to the latest version.
Many smartphones come with built-in new QR code scanners in their camera apps. However, dedicated QR code scanner apps like QR Scanner or QR Code Reader offer enhanced features along with a free QR code. Choose a well-reviewed app to ensure consistent performance.
If your QR code is not displaying correctly when scanned, check the embedded URL for errors. Check that the connected website is operational and mobile-friendly. Additionally, verify that the QR code image is high-quality and free from any physical or digital distortions while creating custom QR codes.
Static QR codes have fixed information embedded directly within them, which means the data cannot be changed once the code is created. They are ideal for permanent, unchanging information like contact details. Dynamic QR codes, on the other hand, store a short URL that redirects to the intended data, allowing the information to be updated or changed without altering the QR code itself.
