How the whatsapp code works

A WhatsApp QR code is a wa.me link in disguise. Scanning it opens a chat with your number, optionally with a message already typed, which makes it excellent for shop windows, receipts and support desks.

The number must include the country code and nothing else — wa.me rejects spaces, dashes and the plus sign, so we strip them for you.

Questions

Is this the same as the QR code inside WhatsApp?
No. WhatsApp's own code links devices or adds contacts. This one opens a chat with a specific number from any camera app.
What if the person doesn't have WhatsApp?
The link opens a WhatsApp web page prompting them to install it. Consider an SMS code as a fallback for a general audience.
Can I change the message later?
Not without generating a new code — the text is baked into the link.
