How RFC 3966 The 'tel' URI for Telephone Numbers Works: Standards & Compatibility
The tel URI scheme formats telephone numbers into tel:<number> syntax. When scanned, iOS and Android operating systems trigger the native phone dialer interface, allowing the user to initiate a voice call with a single tap on the confirmation dialog.

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 immediately initiate the phone call?›
No phone will ever place a call without user permission. Scanning opens a system prompt displaying the number (e.g. "Call (800) 555-0199?"), and the user must tap Call to connect.
Should I include country codes?›
Yes! It is best practice to include the international dial prefix (e.g. +1 for USA/Canada, +44 for UK) so callers roaming or using international SIMs connect without issue.
Can I use letters in the phone number (like 1-800-FLOWERS)?›
It is recommended to convert vanity letter numbers into their numeric keypad equivalents (e.g., 1-800-356-9377) to ensure universal compatibility across all mobile dialers.
Is my phone number stored by QR Studio?›
Never. QR Studio runs entirely in your browser. No telephone numbers are sent to or stored on any server.
