Scan QR Code Master

How to make a QR code that starts a WhatsApp chat

WhatsApp has a 'click to chat' link format that opens a new chat with your number — no need for the person to save your contact first. Turn that link into a QR code and anyone can message you by scanning.

Build your click-to-chat link

  1. Use the format https://wa.me/<number>, where <number> is your full phone number in international format with no plus sign, spaces, or dashes (for example wa.me/14155551234).
  2. Optionally add a pre-filled message: https://wa.me/<number>?text=Hi (spaces become %20).
  3. Open the link once yourself to confirm it starts a chat with the right number.

Make the code

  1. In Scan QR Code Master, open My Codes and create a New Code with the Type set to URL.
  2. Paste your wa.me link and generate the code.
  3. Add it to a flyer, receipt, or storefront so customers can reach you in a tap.

FAQ

Do people need my number saved to message me?
No. A wa.me link opens a chat with your number directly, so scanning the code lets someone message you without adding you as a contact first.
