Phone QR code

What it is, how it works, and when to use it

A Phone Call QR Code starts a phone call the moment someone scans it. When the QR is scanned, the phone’s dialer opens automatically with your number filled in. The user just taps Call.

It’s the fastest way to turn offline visitors, customers, or passers-by into real phone calls. No typing, no copying, no mistakes. It works on all smartphones that support calling.

This type of QR is ideal for support lines, reservations, service requests, property listings, signage, or any situation where you want immediate contact.

How to create a Phone Call QR Code

The Phone Call QR generator on SQR shows one field:

1. Phone number

This is the number the QR will dial when scanned.

Always enter the number in full international format so it works everywhere.
Examples:
+1 202 555 0149
+31 6 12345678
+44 7300 900123

The number cannot be changed after printing.

Common uses

Phone Call QR Codes are perfect for:

  • Customer support hotlines
  • Restaurant, hotel, or spa reservations
  • Real estate “For Sale” or “For Rent” signs
  • Service businesses (plumbers, electricians, repairs)
  • Sales teams who want instant inbound calls
  • Event staff or temporary information desks
  • Medical, dental, or clinic appointments
  • Printed brochures, posters, or business cards

They work especially well when you want fast communication with no friction.

Limitations

  • Requires a device capable of making phone calls
  • Requires mobile reception
  • Static QR Codes cannot be updated after printing
    (Use a dynamic QR link if your number might change)

Best practices

  • Always use international format to avoid dialing issues
  • Add a small label like “Scan to call us”
  • Test on both iPhone and Android
  • Use dynamic if the number may be updated later
  • Place it in visible locations (entrances, counters, menus, signs)

A Phone Call QR Code is the simplest way to turn scans into instant calls and reduce friction for customers.
