Check correct international number format:WhatsApp requires phone numbers to include the country code (e.g. +84 for Vietnam), without leading zeros.
QR codes large enough to be easily scanned:QR codes that are too small can be difficult to scan, especially when printed on packaging, posters or business cards.
Do not use dynamic QR if you need a permanent link (avoid expiration):Dynamic QR codes can expire or have limited number of visits – use only when content needs to be changed later.
Security of information embedded in QR codes:Avoid sharing QR codes publicly if they link to personal information, closed groups, or sensitive content.
Try scanning before sharing widely:Test the code to work well on different devices to avoid errors when users access it.
6. Troubleshooting when QR code is not working
Error entering wrong number or country mismatch:WhatsApp does not recognize if the country code is missing (e.g. +84 instead of 084).
Group QR expired:Group invite links may become invalid after a long period of time or when the admin resets the link.
QR not scannable due to blurry/wrongly sized image:QR codes that are too small, blurry, lack contrast, or are distorted when printed/displayed will not scan successfully.
Solution:
Regenerate a new QR code by double checking the phone number and invitation link are correct.
Ensure image quality: sharp images, correct standard size (~500x500px or more when printed).
Try scanning on multiple devices to determine if the error is due to the image or the code reading app.
For groups with expired links: go back to WhatsApp > Group Info > Reset Invite Link to get a new link.
