Phone QR Code
The Phone QR Code generator is the fastest way for customers to reach your sales or support line. In an era where "click-to-call" is king on the web, "scan-to-call" takes over in the physical world. This tool creates a "tel:" link that, when scanned, opens the phone's native dialer app with your number already entered. This is exceptionally effective on posters, billboards, and business cards, reducing the effort required for a customer to make a call to almost zero.

04Tool-Specific FAQ
Will the phone call start immediately?
No. For security and user control, the scan will open the dialer with the number pre-filled, but the user must still press the "Call" button to initiate the conversation.
Should I include the country code?
Yes, absolutely. To ensure your QR code works for international travelers or users with different regional settings, always use the full international format (e.g., +1 for USA, +44 for UK).
Does this work for SMS?
This specific tool is for phone calls. If you want to pre-fill a text message, you should use our specialized SMS QR code generator (coming soon) or a custom URL using the "sms:" protocol.
Can I use an extension number?
Support for extensions in QR codes is limited and inconsistent across devices. It is best to use a direct line for the most reliable user experience.
