Phone number QR code
One scan and the phone offers to call you. No typing, no misdialled numbers.
What is a phone number QR code?
A phone number QR code shows your number with a Call button when someone scans it, so nobody misdials. It holds a standard tel: link every phone understands, and nothing is dialled until the person taps Call. Use it on vehicles, signs, flyers and equipment.
What’s inside the code
tel:+14155550100
A tel: link with the number in international format. Phones show the number first and dial only when the person taps Call.

The camera shows your number with a Call button. Nothing is dialled until the person taps it.
Free static code
Phone codes are static: the number is printed into the code and can't change. For contact details you can update, use a dynamic vCard, which also carries your name, email and website.
No watermark, and RelyQr codes never expire, on any plan. Static vs dynamic, explained

Printing a phone number QR code
On vans and vehicles people scan from a few metres away, so make it at least 30 cm wide for 3 m. On flyers and door hangers, 2.5 to 3 cm. QR code size chart
- Use a number that will still be yours in a few years; phone codes can't be changed after printing.
- Print it big on vehicles: people scan from further away.
Phone number QR code not working?
- It dials the wrong country
- Add the country code with a +, like +1 or +44, so the number works from anywhere.
- A tablet can't call
- Devices without phone service still show the number, so people can copy it.
- It's hard to scan from a vehicle
- Print it bigger with a light margin; codes on curved or moving surfaces need extra size.
