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.

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

Where people use phone number QR codes

  • Vehicle and van signage
  • “For sale” and “To let” signs
  • Emergency and support contacts on equipment
  • Flyers and door hangers

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.
