How does a WhatsApp QR code work?

When scanned, it opens WhatsApp and starts a new conversation with your number. You can optionally pre-fill a message so the user just taps send.

Do I need to include the country code?

Yes. Include the full international number with country code (e.g. +1 for USA, +44 for UK, +92 for Pakistan) without spaces or hyphens.
