How to Make a QR Code for a Phone Number (Free, 2026)
A phone-number QR code lets anyone call you by scanning it — their dialer opens with your number already filled in, so there's no chance of a typo. It's perfect for business cards, storefront windows, service vehicles, and flyers. Here's how to make one for free.
Quick answer
To make a QR code for a phone number, choose the 'Phone' option in a free QR generator like onesol.io/qr-code-generator and enter your number in full international format (for example, +1 415 555 0100). The tool encodes it as a tel: link, so scanning opens the caller's dialer with your number ready to dial. Download it as a PNG or SVG and add it to your card or sign.
1. Write your number in international format
Enter your number with the country code and a leading plus sign, like +1 for the US or +44 for the UK, and drop the leading zero used for domestic dialing. This format works no matter where the person scanning is located. Double-check every digit, since one wrong number sends every caller to the wrong place.
2. Use the phone or 'tel:' option in a generator
In a tool like onesol.io/qr-code-generator, pick the 'Phone number' type and paste your number. Behind the scenes it creates a tel: link, which is what tells the phone to open its dialer instead of a web browser.
3. Download and place it where people call from
Save a high-resolution PNG or SVG and put the code where a call makes sense — a business card, reception desk, enquiries sign, or delivery van. Add a short label like 'Scan to call us' so people know what will happen when they scan.
4. Test the tap-to-call behavior
Scan the code with both an iPhone and an Android and confirm the dialer opens with the correct number pre-filled — it should not place the call automatically, only prepare it. If nothing happens, re-check that you used the tel format and included the country code.

FAQ
Does scanning the code call the number automatically?
No — it opens the phone's dialer with your number pre-filled, and the person still taps the call button. This is a safety feature built into phones to prevent accidental calls.
Should I include the country code?
Yes. Always use the full international format with a plus sign and country code (like +1 or +44) so the code works for anyone calling from anywhere, including tourists and overseas customers.
Can I use the same code for calls and texts?
One code does one thing. A tel: QR code opens the dialer to call; to let people text you instead, make a separate SMS QR code, or point a single code at a contact page that offers both options.
Will this work on old phones?
Most phones from the last several years scan tel QR codes with the built-in camera. Very old devices may need a free QR scanner app, but the tap-to-call behavior itself is standard.
