WhatsApp recently added the ability for users to add new contacts through QR codes. Each user has a QR code they can share with others, and when someone scans their code, they will receive their number. Our guide will show you how to share your QR code.
Note: These screenshots were captured in the WhatsApp application on iOS.
Step 1: Tap “Settings” in the bottom-right corner of the screen.
Step 2: Tap the QR code icon to the right of your name.
Step 3: From there, another user can point their WhatsApp camera at your QR code (represented by the large black square in the image below) to receive your number. If you want to save a picture of your QR code, or share your code through another app or text message, tap the “share” icon in the top-right corner of the screen.
