📘 About the WhatsApp QR Code Generator

A WhatsApp QR code opens a chat with your number as soon as someone scans it — they do not need to save your contact first. Add a ready-typed message such as "Hi, I want to order…" to make it even easier.

It uses WhatsApp's official wa.me click-to-chat link, so it works with WhatsApp and WhatsApp Business on Android and iPhone.

💡 How to use the WhatsApp QR Code Generator

  • Enter your country code (91 for India) and your WhatsApp number without the leading 0.
  • Optionally type the message the customer will see ready to send.
  • Download the QR code for your shop counter, visiting card, menu or social posts.

💡 Tips for a QR code that always scans

  • Print it at least 2 × 2 cm (about 1 inch); bigger if people will scan from far away — roughly one tenth of the scanning distance.
  • Keep a light background and a dark code. Light codes on dark backgrounds fail on many phones.
  • Leave the white border (margin) around the code.
  • Test it with two or three phones before printing hundreds.
  • Choose High error correction if the code may get scratched or you place a small logo over it.

❓ Frequently asked questions

Does it work with WhatsApp Business?

Yes. The wa.me link opens a chat with any WhatsApp or WhatsApp Business number.

Do people need to save my number?

No. Scanning opens a chat with your number straight away, even if it is not in their contacts.

Do these QR codes expire?

No. The QR code stores your information directly, so it works for ever, with no sign-up, tracking or scan limit. It only stops working if the link or details inside it change.

Can I change the message later?

The message is stored inside the QR code, so to change it, make a new code.
