How to use it
Enter the phone number with the country code (e.g. +1 555 123-4567 for the US), and, if you want, a message that will already appear ready in the chat. Click Calculate to generate the wa.me link — anyone who clicks it opens a direct chat with that number on WhatsApp (mobile or WhatsApp Web), even without having the number saved.
Why the country code matters
The wa.me link requires the full number, including the country code, without any local dialing prefix such as a leading "0".
Frequently asked questions
Is my phone number uploaded to a server?
No — the link is built entirely in your browser using WhatsApp's public wa.me format. Nothing is sent to us.
Does the person clicking the link need to have my number saved?
No — that's exactly the point of a wa.me link: it opens the chat directly, no need to save the contact first.
Does it work for any country?
Yes, as long as you enter the full number with the correct country code.
