Scanning this QR code with a smartphone camera or QR app opens the dialer with the number filled in. Placing the call still requires pressing the call button.

Detailed description of each setting

Phone number

The number to dial. Hyphens and spaces are stripped automatically and embedded in tel: format (e.g. tel:14155550100). To include a country code, prefix it like +1 (the leading + is preserved).

About the tel: format

This tool generates the widely supported tel:number format. Scan behavior varies by device; most environments only open the dialer with the number filled in, and placing the call requires the user's action.

Error correction / size / margin

Error correction is the share of a damaged code that can still be recovered (L≈7%, M≈15%, Q≈25%, H≈30%). Size is the output PNG edge in pixels; margin is the white quiet zone around the code (4 or more recommended). For print, a larger size scans more reliably.

Frequently asked questions (FAQ)

What is a phone number QR code?

A QR code that embeds a phone number in tel: format. When scanned with a smartphone, it opens the dialer with the number filled in — an easy one-tap call action for cards, flyers, and signage.

Does scanning place the call automatically?

No. On most devices it only opens the dialer with the number filled in; the user must press the call button. Behavior varies by device, and it never dials on its own.

Is the number I enter safe?

Yes. Everything from entering the number to generating and downloading the QR code runs entirely in your browser (JavaScript). Your input is never sent to a server.
