How to create a WhatsApp QR code
A QR code can open a conversation without making someone type the number. Proper preparation prevents broken links and wrong expectations.
Use the international number format
Enter the phone number with its country code and without unnecessary spaces or symbols. Check it on another device before printing.
The starter message is optional
Prefilled text can reduce friction, but people can still review it before sending. Do not treat a QR as automatic message delivery.
Test the destination before publishing
Scan the QR on iOS and Android, confirm the phone number, and verify that the expected chat opens.
