A WhatsApp QR code encodes a special link that opens WhatsApp directly to a chat with your number — with an optional pre-filled message. The person scanning never has to save your contact or type anything; they just scan, and the chat opens ready to go.
Where this works well
- Storefront windows and counters — customers ask questions before walking in.
- Restaurant table cards — quick orders or questions straight to WhatsApp.
- Product packaging — instant support access after purchase.
- Business cards and flyers — a lower-friction alternative to a phone number someone has to save first.
Step-by-step: creating your WhatsApp QR code
1. Use your WhatsApp Business number in international format
Include the country code without the leading zero — for example, a UK number starting 07... becomes 44 7.... Getting this format wrong is the single most common reason a WhatsApp QR code doesn't open the right chat.
2. Add a pre-filled message (optional but recommended)
Something like "Hi, I'd like to ask about..." saves the customer a blank-page moment and tells you immediately where they found you.
3. Generate and place it where people will actually see it
Head to the WhatsApp QR code generator, fill in your number and message, then download. Table cards, checkout counters, and packaging inserts tend to get scanned far more than a code buried on a website footer.

Does the person need WhatsApp installed to scan this?
Yes — scanning opens the WhatsApp app (or WhatsApp Web on desktop) directly. If they don't have it installed, they'll be prompted to download it.
Can I change the pre-filled message later?
Not on the same code — the message is encoded into the QR code itself. You'd need to generate a new code with the updated message.
Does this work with a regular WhatsApp number or only WhatsApp Business?
Both. The underlying link format works the same whether you're using a personal WhatsApp account or WhatsApp Business.
