Encodes a `tel:` link. Scanning offers to call the number. The phone asks first rather than dialling immediately, on every platform.

How to make a phone qr code

1 Fill in the fields. The code updates as you type.
2 Raise the error correction if it will be printed small or might get covered.
3 Download it as PNG for the web or SVG for print: SVG stays sharp at any size.

Use the full international format with the plus sign and country code. A local number works when the person is in the same country and fails silently abroad, which is the worst kind of failure for a printed sign. Spaces and dashes inside the number are ignored by phones, so format it for human readability if the number is also printed. Because a tel: payload is very short, the resulting code is sparse and scans reliably even printed small or on a curved surface — which makes it a good choice for a vehicle or a shop window.

Questions

No. Every platform asks first, which is why a phone QR code is not a security risk.
