What is SMS QR Code?
An SMS QR code encodes an SMSTO link containing a phone number and an optional message body. Scanning it opens the messaging app with the recipient and text already filled in, so the user only has to press send — a low-friction way to run opt-ins, votes and support requests.
Common Uses for SMS QR Code
- Text-to-join opt-ins and contests
- Support numbers with a pre-written keyword
- Feedback requests on receipts
- Event voting or polling

Frequently Asked Questions
What format does an SMS QR code use?
The SMSTO scheme: SMSTO:number:message. Most phone cameras and QR apps understand it and open the messaging app pre-filled.

Yes. Put the text after the second colon and it appears in the message body, though users can still edit or delete it before sending.
Are there charges?
The QR code itself is free; normal carrier text-message rates apply to the user when they send.
