WhatsApp QR codes can be used for a variety of purposes within the popular messaging application. Here are some of the main uses for WhatsApp QR codes:
Adding contacts
One of the primary uses of WhatsApp QR codes is to easily add new contacts. Each user has a unique QR code that can be scanned to add them as a contact. To find your QR code on WhatsApp:
- Open the WhatsApp app
- Go to Settings > Profile > QR code
You can then show your QR code to someone in person or send them a screenshot, allowing them to scan it and instantly add you as a contact. This provides a quick and easy way to exchange contact information.
Joining WhatsApp groups
WhatsApp groups also have unique QR codes that can be used to add people to the group. The group admin can generate a code that members can scan to join. This allows quick access to group chats without having to manually add each person’s phone number.
Connecting to WhatsApp Web/Desktop
Scanning the QR code on WhatsApp Web or WhatsApp Desktop with your phone allows you to link your account to the desktop version. Once linked, you can access your chats and messages on a larger screen for added convenience.
Verifying authenticity
Since each user and group has a unique QR code, scanning a code can help verify authenticity and avoid fraud. For example, scanning a code rather than clicking on a link in a message helps ensure it is really associated with the expected contact or group.
Business profiles
Businesses can generate a WhatsApp QR code to allow customers to easily message or engage with them. Scanning the code opens a chat window with the business account, streamlining communication.
How to scan a WhatsApp QR code
Scanning a WhatsApp QR code is very simple whether you are on iPhone or Android:
- Open the WhatsApp app
- Go to Settings > Profile > QR code > Scan code
- Point your phone’s camera at the QR code to scan it
You may have to move the camera around to get the proper focus and scan angle. Once recognized, the code will automatically open the associated chat, contact or group.
Troubleshooting tips
If you are having trouble scanning a WhatsApp QR code, try the following tips:
- Make sure your camera is clean and free of defects or obstructions

With good positioning and lighting, most modern smartphone cameras should be able to easily scan WhatsApp QR codes.
QR code security
While very convenient, it’s important to understand WhatsApp QR code security considerations:

As with sharing any personal information online, it’s smart to exercise some caution when utilizing WhatsApp QR codes to protect your account.
