Frequently asked questions
- What happens when someone scans a WhatsApp QR code?
- WhatsApp opens with a chat to your number and your message prefilled — the scanner just taps send. If they do not have WhatsApp installed, the link opens in the browser and offers it.
- Why does the number need a country code?
- WhatsApp identifies accounts by full international number, so the country code is required — +14155552671, not just 4155552671. The + and spaces are stripped automatically; without the right country code the chat simply will not open.
- Do people need my number saved to chat with me?
- No — that is the magic. The code opens the chat directly without them saving your contact first, which is why these work so well on shop windows, menus, and support desks.
- Is my number kept private?
- The code is generated in your browser, free with no signup — we never see it. But the number is encoded in the code itself, so anyone who scans can read it. Use a business number if you would rather keep your personal one private.
