How the WhatsApp QR code works
WhatsApp provides a public “click to chat” address: https://wa.me/<number>?text=<message>. MyQRGenerator builds that link — digits only, with the message URL-encoded so spaces, emoji and line breaks survive — and encodes it in the QR code. On a phone it opens WhatsApp; on a computer it opens WhatsApp Web.
Good uses
- Shops and restaurants: “Scan to order on WhatsApp” on the counter or menu.
- Service businesses: “Hi, I'd like a quote for…” pre-filled on flyers.
- Events: RSVP by WhatsApp with the event name already in the message.
WhatsApp QR code vs. WhatsApp's own QR
WhatsApp Business can show a QR code for your profile inside the app. That code opens your chat but is tied to the app's short-link service, and you can't choose the colours or download it as a vector file. A wa.me QR code from MyQRGenerator points to the same chat, can include any pre-filled message, works for personal and business numbers, and can be styled and exported as SVG or PDF for print.
Formatting the number correctly
WhatsApp needs the full international number without the plus sign, spaces or a leading zero: India 91 + 9876543210 becomes 919876543210. Typing 098765… or adding the country code twice are the most common reasons the chat opens with “phone number shared via url is invalid”. The form strips formatting for you and shows the final link under “Encoded content”.
Tips
- Keep the pre-filled message short; it makes the code smaller and is easier to edit.
- Mention what will happen near the code, e.g. “Scan to chat with us on WhatsApp”.
- Test with a phone that has never messaged your number.
