WhatsApp QR Code: Let Anyone Start a Chat With One Scan
Stop giving out your WhatsApp number verbally or making people save your contact just to message you. A WhatsApp QR code opens a direct chat with you the moment someone scans it — no contact saving, no number typing.
What is a WhatsApp QR code?
A WhatsApp QR code encodes a wa.me/ link that opens WhatsApp and starts a chat with your number. It works on any smartphone with WhatsApp installed — iOS, Android, or WhatsApp Web on desktop.
You can optionally include a pre-filled message so the conversation opener is already written for the customer — ideal for support flows, order queries, or appointment requests.
