What is an SMS QR Code?
An SMS QR code encodes a link that opens the default SMS app with a phone number and optional message already filled in. The user taps send—or edits the message first—and the text goes out.
This is useful for campaigns, feedback requests, support hotlines, and anywhere you want to lower friction for sending a text.
Best Practices
Include the country code for international compatibility. Keep the pre-filled message short and actionable (e.g., "Yes, sign me up" or "I need help with my order").
Use on posters, receipts, packaging, and ads. The QR code works on any smartphone with a camera and messaging app.
