Phone QR Code Generator for Calls, Contacts & Service Businesses
A phone QR code is one of the simplest ways to convert offline attention into a phone call. When scanned, it opens the dialer with the number pre-filled. This removes the friction of typing a phone number and increases call rates.
This guide explains how to use phone QR codes for local businesses, real estate, healthcare, and customer service.
How Phone QR Codes Work
Phone QR codes use the tel: protocol. When a smartphone scans the code, it prompts the user to call the embedded number.
