Create a WhatsApp QR code that opens a conversation with an optional prefilled message.

Last reviewed: July 30, 2026

What the QR code contains

A WhatsApp QR code normally stores a wa.me link with the phone number in international format. The optional text parameter can prefill the first message, but the visitor still chooses whether to send it.

Build it correctly

Use the full country code without spaces in the final link.
Keep the opening message short and useful.
Avoid placing confidential information in the prefilled message.
Test on both iPhone and Android before printing.

Where to use it

Good placements include storefront signs, service vehicles, appointment cards, product packaging and support documents. Keep a normal contact option visible for people who do not use WhatsApp.
