Phone QR Codes

Create a QR code that opens the dialer with your number ready to call

What are Phone QR Codes?

A phone QR code encodes a tel: link. Scanning it opens the phone's dialer with the number filled in; the caller confirms with one tap. The code never dials by itself, so an accidental scan can't place a call.

Common uses

  • Business cards and contact sharing
  • Customer service and support
  • Emergency contact information
  • Restaurant reservations

Phone Number Format

Use international format: a plus sign, the country code, then the number. A local number like 555-123-4567 works for local scanners but fails for anyone abroad; +1-555-123-4567 works for both. Dashes and spaces are fine — phones ignore them.

US number

+1-555-123-4567

Country code +1, then area code and number

UK mobile

+44-7700-900123

Country code +44, leading 0 dropped

Toll-free

+1-800-555-0199

Toll-free numbers take a country code too

With extension

+1-555-123-4567,204

A comma pauses, then dials the extension
