A phone call QR code triggers a call to a specified number the moment it's scanned. No dialing, no searching — just scan and call. Create one at QRMax.

What It Does

The QR code encodes a tel: URI. When scanned from a smartphone, it opens the dialer with the number pre-filled, and the user taps to confirm the call.

Common Use Cases

Use CaseExample
Customer support"Scan to call our help line" on packaging
Business cardsInstant dial from your printed card
Real estate signsCall the listing agent directly
Restaurant tables"Call to reorder" or "Call for pickup"
Emergency infoQuick-dial for safety or medical contacts

How to Create a Phone Call QR Code

  1. Choose "Phone" type — Open QRMax and select the phone call option.
  2. Enter the phone number — Include the full international dialing code (e.g., +1-555-123-4567).
  3. Customize & download — Add brand colors and a phone icon, then export.

Practical Tips

  • Always use international format — Include the country code so the QR works for scanners anywhere in the world.
  • Add a label near the QR — Print "Scan to Call" next to the code so users know what to expect.
  • Consider business hours — If your line isn't 24/7, note your hours near the QR code.

Does the call start automatically?

No. For security, smartphones show the number and require the user to tap "Call" to confirm. The QR just pre-fills the dialer.

Can I use an extension or pause?

Some dialers support commas (pause) and semicolons (wait) in tel URIs, but support varies by device. Test before relying on extensions.

Does it work on tablets and desktops?

Tablets with calling capability will work. Desktops may open a VoIP app like FaceTime or Skype if configured.
