Phone QR Codes: The Complete Guide
Phone QR codes make it incredibly easy for customers and contacts to call you directly. When scanned, these QR codes automatically initiate a phone call to the specified number, eliminating the need to manually dial numbers.
Why Use Phone QR Codes?
- Instant Calling: Customers can call you with just one scan
- No Typing Required: Eliminates errors from manual number entry
- Professional Contact: Perfect for business cards and marketing materials
- International Numbers: Works perfectly with country codes
- Lead Generation: Easy contact method for potential customers
- Emergency Contacts: Quick access to important phone numbers
How Phone QR Codes Work
Phone QR codes use the "tel:" protocol, which is a standard way for mobile devices to initiate phone calls. When scanned:
- The QR code contains a tel: link (e.g., tel:+15551234567)
- Scanning opens the device's phone dialer
- The number is automatically entered and ready to call
- User just needs to tap the call button
Best Practices for Phone QR Codes
1. Include Country Codes
Always include the country code (+1 for US, +44 for UK, etc.) for international compatibility
2. Use Standard Format
Format numbers consistently: +[country code][area code][local number]
3. Test on Mobile Devices
Phone QR codes only work on devices with phone capabilities
4. Clear Context
Include text like "Scan to Call" near the QR code
5. Professional Numbers
Use business phone numbers rather than personal mobile numbers

Frequently Asked Questions
What is a Phone QR Code?
A Phone QR Code contains a tel: link that, when scanned with a smartphone camera, automatically opens the phone dialer with the number ready to call.
Do I need to include country codes?
Yes, it's highly recommended to include country codes (+1, +44, +91, etc.) to ensure the number works internationally and for all mobile carriers.
What if someone scans this on a device without phone capability?
Phone QR codes only work on smartphones and devices with calling capabilities. On other devices, the scan might not trigger any action or could display an error.
Can I use extensions or special characters?
It's best to keep phone numbers simple with just digits and the plus sign for country codes. Special characters, extensions, and pauses are not well supported across all devices.
