How Standard SMSTO / SMS URI Protocol Works: Standards & Compatibility
SMS QR codes use the SMSTO:<number>:<message> URI scheme. When scanned by an iOS or Android smartphone, the native SMS messaging app opens immediately with the phone number and pre-composed message ready for dispatch.

Printing & Quality Guidelines
Follow these ISO/IEC 18004 recommendations to ensure instant, frictionless scans:
Maintain strong contrast: ensure dark foreground elements on a clean light background.
Observe the Quiet Zone: leave at least 4 modules of blank white margin around the QR code.
Test before bulk printing: scan the physical printed sample on both iOS Camera and Android Google Lens.
Use vector SVG for print production: SVG scales infinitely without pixelation on large signage or menus.
100% Client-Side Privacy Guarantee
QR Studio never stores, tracks, or analyzes your input payload. All matrix math, Reed-Solomon error correction encoding, and image rendering occur directly in your browser.
Frequently Asked Questions
Does scanning the QR code automatically send the SMS?›
No. Smartphone operating systems require explicit user confirmation. Scanning pre-populates the text in the Messages app, and the user must tap the send icon.
Can I use shortcodes (e.g. 5 or 6 digits) instead of phone numbers?›
Yes! You can enter both full international telephone numbers and commercial carrier shortcodes.
Are there character limits for SMS text messages?›
Standard single SMS messages contain up to 160 GSM characters. While you can encode longer messages, keeping them concise ensures faster scanning and compatibility across all carriers.
Does QR Studio track phone numbers?›
No. All processing is 100% client-side in your browser. We never log, store, or transmit your contact numbers or messages.
