  4. 4A scan opens WhatsApp straight to a chat with you, no number to save first.

Questions

What number format should I use?+

Full international format: country code plus the number, no leading zero, no spaces needed. The generator strips everything except digits, so +90 555 123 45 67 and 905551234567 produce the same code.

Does this work without saving the contact?+

Yes. The QR code opens a chat with your number directly through WhatsApp's own wa.me link, so the person scanning never has to add you as a contact first.

Can I change the number or message after printing?+

Not with a plain WhatsApp QR code, it is static. If you expect the number or campaign message to change, point the code at a short link from your LINKNOWN dashboard instead and edit the destination any time.

Want to customize it and track scans?

A free LINKNOWN account lets you brand the QR code, change where it points after printing, and see how many times it was scanned.
