What happens when someone scans an SMS QR code?

Their phone opens the messaging app with the number and any prefilled message ready — they just review and tap send.

Do I have to include a message?

No. Only the phone number is required; the message body is optional and only added when you fill it in.

Is my message content uploaded anywhere?

No. The SMS link and QR code are generated entirely in your browser; nothing is sent to a server.

A scannable shortcut to a prefilled text

An SMS QR code encodes a phone number and an optional message using the widely supported SMSTO format. When someone scans it, their phone opens the messaging app with everything filled in — handy for opt-in campaigns, support lines and contact prompts.

Enter the number and message, download the code as PNG or SVG, and add it to posters, packaging or ads. Everything is generated in your browser, so nothing is uploaded.
