What is a Call QR Code?
A Call QR Code is a scannable QR code that directly dials a phone number when scanned. Instead of typing a number manually, users simply point their smartphone camera at the code to initiate a call—no apps, no typing, no hassle.
How it works
- Encode a phone number: The QR code stores a tel: link (e.g., tel:+1234567890).
- Scan and connect: When scanned, the user’s phone automatically opens the dialer with the number pre-filled.
- One-tap calling: The user taps “Call” to connect instantly.
Unlike traditional contact methods, Call QR Codes work across physical and digital mediums—business cards, billboards, packaging, emails, and more. By reducing the effort required to manually type the number, they help customers reach businesses with minimal effort.
Why should you use a QR Code to receive phone call responses?
- Reduce the barrier to contact and increase response rates
- Simplify your brand’s touchpoints.
- With dynamic QR codes, you can gain insights into who is scanning your QR and from where.
Now that you know what a Call QR Code is and why it matters, let’s dive into creating one.
How to create a Call QR Code
Step 1: Select the “Phone” option on the top pane.
Go to The QR Code Generator or scroll to the widget at the top, then select the phone option.
Step 2: Add the correct country code followed by the phone number
For example, use +1 (country code for the U.S.) and add the phone number tel:+1234567890
Optional: Scroll through the list of options to customize the design of your QR Code
Step 3: Click the “Download” button
The QR Code will be saved locally to your device. You can also use the copy button and then paste the QR Code on your existing design.
Note: Some features require you to use a dynamic QR Code. These include:
- Tracking your QR Codes
- Creating editable QR Codes where the phone number can be changed
- Adding a custom logo on your QR Code
Whenever you select one of these features, you’ll be redirected to our dynamic QR Code sign-up page, where you can access them for free. Alternatively, sign up for free and unlock all our features instantly.
Best Practices to keep in mind while creating QR Codes for phone numbers
Now that you know how to create a Call QR Code, let’s ensure it’s optimized for seamless customer interaction. A well-designed Call QR Code simplifies communication, boosts engagement, and reflects professionalism. Here’s how to make yours effective:
Format the phone number correctly
Use the tel: protocol (e.g., tel:+1234567890) and include the country code (e.g., +1 for the U.S.). This ensures compatibility across devices and regions. Avoid spaces or special characters, and test the code to confirm it auto-dials the correct number.
Prioritize scannability
- Size: Ensure the QR code is at least 2×2 cm (0.8×0.8 in) when printed. For digital use, keep it above 200×200 pixels.
- High contrast: Use dark colors on a light background (or vice versa). Avoid gradients or patterns that interfere with scanning.
- Quiet zone: Leave a blank margin around the code to prevent scanning errors.
Customize for brand recognition
Add your logo, brand colors, or a custom frame to the QR code. Tools like The QR Code Generator let you personalize designs while maintaining scannability. Ensure the logo doesn’t obscure more than 30% of the code.
Add a clear call-to-action (CTA)
Include a short, actionable message like:
- “Scan to Call Us”
- “Quick Connect: Scan to Dial”
Place the CTA underneath the QR Code to guide users and encourage scans.
Test across devices and scenarios
Scan the code on iOS, Android, and older devices to confirm it opens the dialer. Test with and without the internet (for dynamic vs. static codes). Simulate low-light conditions if the code will be displayed in dimly lit areas (e.g., restaurants).
Use dynamic QR codes for tracking
Upgrade to a dynamic QR code to track metrics like:
- Total scans, Unique scans
- Scan locations (geotagging)
- Device types (mobile vs. tablet)
- Operating systems (Android, iOS)
This data helps refine placement and marketing strategies.
Place your QR at right places for visibility
Display your Call QR Code where customers are most likely to need quick contact:
- Physical materials: Business cards, storefronts, receipts, product packaging, brochures.
- Digital platforms: Email signatures, websites, social media profiles, digital ads.
Encode pauses or extensions for complex numbers
If your phone system requires extensions or menu navigation, use commas (,) for pauses or semicolons (;) for extensions (e.g., tel:+1234567890,,,1234). Test thoroughly to ensure seamless dialing.
Ensure accessibility
Pair the QR code with a printed phone number for users unable to scan. Avoid placing codes in hard-to-reach areas (e.g., high ceilings or crowded designs).
Use dynamic QR Codes in case you wish to update your number in the future
If your phone number changes, dynamic QR codes let you update the linked number without reprinting the code. Static codes require regeneration.
Educate your audience
Briefly explain how to scan the code, especially in environments where QR codes are less common. In such scenarios, you can use more descriptive CTAs like “Use your phone’s camera to scan and call instantly!”
Leverage urgency or incentives
Add context to encourage scans, for example:
- “Scan for 24/7 Support”
- “Scan to Skip the Wait!”
Top use cases for call QR Codes
Call QR Codes streamline communication by turning static phone numbers into actionable links. Here are the most impactful ways to leverage them:
1. Promotional Materials
Boost engagement by embedding Call QR Codes in flyers, posters, or digital ads. Customers can instantly connect with your sales or support team without typing numbers.
Example: Add a QR code to a billboard with a CTA like “Scan to Book Your Free Consultation!”

Frequently Asked Questions
Can I customize the design of my Call QR Code?
Yes! Many generators allow you to adjust colors, add logos, or embed branding elements. Ensure the code remains scannable by maintaining contrast between the QR code and background.
Will the QR Code work on all smartphones?
Most modern smartphones can scan call QR codes. Scanning opens the device’s dialer with the number pre-filled. Older devices may require a third-party QR scanner app.
Can I track how many people scanned my Call QR Code?
You can track how many people scanned your QR only if you use a dynamic QR code. Dynamic codes (paid) provide analytics like scan counts, locations, and timestamps. Whereas, static call QR codes do not offer tracking.
Do customers need internet access to use a Call QR Code?
No. Once scanned, the phone number auto-populates in the dialer. Internet is only required if the QR code links to an online redirect service.
Can I include extensions or pauses in the phone number?
Yes. Use commas (,) to add pauses or semicolons (;) for extensions (e.g., +1234567890,,,1234). Test the code to ensure it works with your phone system.
Do Call QR Codes expire?
Static QR codes (directly encoding the number) never expire. Dynamic codes may expire if your QR code service provider restricts access or deletes the code.
Can I use one QR Code for multiple phone numbers?
No. A single QR code links to one number. To direct users to multiple numbers, create separate codes or use a dynamic QR code that redirects to a menu (requires internet).
Is it free to create a Call QR Code?
Yes. Basic static call QR codes are free on most platforms. Paid plans unlock dynamic features like tracking and design customization.
What if I change my phone number later?
Static codes must be recreated. With dynamic QR codes, you can update the linked number without changing the code.
Can I use a Call QR Code for international numbers?
Yes. Include the country code (e.g., +1 for the US) to ensure compatibility across regions.
Are Call QR Codes secure?
Yes, as long as you generate them through a trusted tool. Avoid using unverified generators that could redirect to malicious numbers.
Can I add a message like “Scan to Call Us”?
Absolutely! Add text or a call-to-action (CTA) like “Scan to Call” near the code to encourage scans.
Will the QR Code work if printed in black and white?
Yes, as long as there’s sufficient contrast (e.g., black code on white background). Avoid gradients or low-contrast designs.
Can the QR Code redirect to a voicemail or automated menu?
Yes. Encode the number with pauses (,) to navigate automated systems (e.g., +1234567890,,,1,,# to select menu options).
What’s the best tool to create a Call QR Code?
The QR Code Generator is a user-friendly option for creating static QR Codes, which are free forever, and for dynamic QR Codes that enable tracking.
How do I test my Call QR Code?
Scan it with multiple devices to ensure it opens the dialer with the correct number. Verify pauses/extensions work as intended.
Can I use a Call QR Code in digital ads or emails?
Yes! Embed it in digital materials like emails, websites, or social media. Ensure the size is large enough for easy scanning.
