Open a WhatsApp chat without saving the number

How it works

1. Paste or type the number in any format, for example 0152 1234567 or tel:+49…
2. Check the country. It is picked from your time zone, and the national 0 is replaced with the country code.
3. Write a message if you like, then tap “Open in WhatsApp”.

Questions

Do I need to save the number to my contacts?

No. The page builds a wa.me link, and WhatsApp opens a chat with that number directly.

Is the number stored or sent anywhere?

No. Everything happens in your browser. Only your last message and chosen country are kept on your device.

Does it work with WhatsApp Business?

Yes. Your phone opens the WhatsApp app it has installed. If both are installed, it uses the default one.
