How a WhatsApp QR code works
A WhatsApp QR code contains a wa.me link — WhatsApp's official click-to-chat address. When someone scans it with their phone camera, WhatsApp opens a chat with your number, with your message already typed in. They don't need to save your number first, which removes the biggest barrier to getting a message from a new customer.
Where to use your WhatsApp QR code
- Shop counters and billing desks — let customers order again or ask about stock later.
- Product packaging — offer support, reorders or warranty help over chat.
- Visiting cards and flyers — one scan instead of typing a 10-digit number.
- Restaurants and cloud kitchens — take takeaway or delivery orders directly.
- Real estate boards and vehicle stickers — capture enquiries from people passing by.
Tips for a QR code that gets scanned
- Always include the country code. Without it, WhatsApp cannot find the number.
- Keep the pre-filled message short and specific, so you know where the lead came from (for example “Hi, I saw your flyer at the mall”).
- Print it at least 2 × 2 cm, and larger if people will scan it from a distance.
- Use a WhatsApp Business account if you want automated greeting messages and a catalogue.
