How to do it, step by step
- Type the number with the country code (and area code), so it works for callers abroad.
- Customize the look and test the scan.
- Download the code.
When this is useful
A “for sale” or “for rent” sign
Whoever passes on the street scans and calls, without writing down the number.
Service poster or flyer
It reduces the friction between seeing the ad and making the call.
Tips for a good result
- Use the international format (+1 415 555 0100) so it also works abroad.
- To open a chat instead of calling, use the WhatsApp QR Code.
What this tool does not do
- The code only starts the dialing: the person still confirms the call on the phone.
- It is static: if the number changes, generate another code.
Frequently asked questions
- Does it need an area code?
- Yes. Without a country and area code, a phone in another region may call the wrong number.
- Can I save the contact instead of calling?
- Yes, use the business card (vCard) QR Code.
