Frequently Asked Questions
How do I make a WhatsApp QR code?
Go to QRCodeGen.ai and select 'URL' as the QR code type. Enter the WhatsApp click-to-chat link: https://wa.me/15551234567 (replace with your phone number in international format, no + or dashes). Optionally add a pre-filled message with ?text=Hello. Customize and download your QR code.
What is the WhatsApp click-to-chat link format?
The format is: https://wa.me/[phone number]?text=[pre-filled message]. The phone number should be in international format without the + sign (e.g., 15551234567 for a US number). The text parameter is optional and should be URL-encoded. Example: https://wa.me/15551234567?text=Hi%20I%20want%20to%20place%20an%20order
Does the customer need my number saved to use the QR code?
No. That's the key advantage of WhatsApp click-to-chat links. When someone scans your QR code, WhatsApp opens a chat with your number directly — they don't need to save your number first. This removes a major friction point for customer communication.
Can I pre-fill a message in the WhatsApp QR code?
Yes. Add ?text=Your%20Message to the WhatsApp URL. The message will appear pre-typed in the chat input when the customer opens the link. They can edit it before sending or tap send immediately. Great for order inquiries, support requests, or appointment bookings.
Does a WhatsApp QR code work on iPhone and Android?
Yes. WhatsApp QR codes work on any device with WhatsApp installed. When scanned, the phone's browser redirects to the WhatsApp app. If WhatsApp isn't installed, the user is directed to WhatsApp Web or the app store.
Can I use a WhatsApp QR code for WhatsApp Business?
Absolutely. WhatsApp Business uses the same wa.me link format. Use your WhatsApp Business number in the QR code and customers will chat directly with your business profile, complete with your business name, description, and catalog.
Where should I display my WhatsApp QR code?
Common placements: restaurant tables (for ordering or feedback), product packaging, business cards, store windows, flyers, receipts, and social media posts. Anywhere you want to make it easy for customers to start a conversation with your business.
Is a WhatsApp QR code free to create?
Yes. QRCodeGen.ai generates QR codes completely free — no limits, no watermarks, no account required. The QR code simply encodes the WhatsApp URL, and QRCodeGen.ai processes everything in your browser so your data stays private.
