Frequently Asked Questions
How do I create a QR code that sends an SMS?
Enter the recipient phone number (with country code) and optional pre-filled message. The tool generates a QR code using the sms: URI scheme. When scanned, it opens the messaging app with the number and message ready to send.
What is the format for an SMS QR code?
The QR code encodes: sms:+15551234567?body=Hello. The phone number should include the country code. The body parameter pre-fills the message text. The tool handles URL encoding of special characters in the message automatically.
How long can the pre-filled SMS message be?
Standard SMS limit is 160 characters (GSM-7 encoding) or 70 characters (Unicode). Keep QR code messages under 100 characters for reliable scanning. The QR code itself can hold more, but the SMS app will split long messages into multiple parts.
Where are SMS QR codes commonly used?
Opt-in marketing (text JOIN to subscribe). Customer feedback (text your rating). Event registration. Two-factor authentication setup. Voting and polls. Contest entries. They simplify the process of sending a specific message to a specific number.
Do SMS QR codes work on both iPhone and Android?
Yes, but the URI format differs slightly. iOS uses sms:+1555123456&body=text while Android uses sms:+1555123456?body=text. The tool generates a compatible format that works on both platforms by using the most widely supported syntax.
