How It Works
Enter Your WhatsApp Number
Type your phone number with country code but without the + sign or leading zeros. For example, a Nepali number +977-9812345678 becomes 9779812345678, and a US number +1 (415) 555-1234 becomes 14155551234.
Add a Pre-filled Message
Optionally write a message that will appear in the chat input when someone scans. Something like "Hi, I'd like to place an order" or "I saw your ad and want more info." The user can edit it before sending.
Share Your QR Code
Your QR code generates instantly as you type. Download it and print on business cards, menus, flyers, product packaging, or display it on your website and social media.
Popular Use Cases
Customer Support
Place a WhatsApp QR code on product packaging or receipts. Customers scan to instantly reach your support team without searching for your number or navigating a website.
Restaurant Ordering
Print WhatsApp QR codes on table tents or menus. Customers scan to open a chat with "I'd like to order from Table 5" pre-filled — perfect for takeaway and delivery orders too.
Business Cards
Add a WhatsApp QR code to your business card. Instead of saving your number and typing a message, new contacts scan and instantly start a conversation with you.
Real Estate Listings
Place WhatsApp QR codes on property signs, brochures, and online listings. Interested buyers scan to ask about the property with a pre-filled message like "I'm interested in the property at 123 Main St."
Event Registration
Share a WhatsApp QR code on event posters or social media. Attendees scan to register or ask questions directly, with a message like "I'd like to register for the Saturday workshop."
Appointment Booking
Clinics, salons, and service businesses can use WhatsApp QR codes so clients can book appointments with a single scan. Pre-fill "I'd like to book an appointment" to get the conversation started.
Tips for Best Results
- Use your business WhatsApp number. If you have a WhatsApp Business account, use that number for professional features like auto-replies, quick responses, and business profiles.
- Format the number correctly. Use only digits with the country code — no plus sign, spaces, dashes, or parentheses. The wa.me link format requires clean numbers.
- Keep the pre-filled message helpful. A specific message like "Hi, I saw your ad on Facebook and I'm interested in the Premium package" converts much better than a generic "Hello."
- Add context near the QR code. Include text like "Scan to chat with us on WhatsApp" so people know what will happen when they scan.
- Test before printing. Scan your QR code on both iPhone and Android to make sure WhatsApp opens correctly and the message appears in the chat input.
Frequently Asked Questions
Does the person scanning need WhatsApp installed?
Yes. The QR code opens a wa.me link which redirects to WhatsApp. If WhatsApp is not installed, the link will redirect to the WhatsApp download page. On desktop browsers, it opens WhatsApp Web if the user is logged in.
Will the message send automatically?
No. The pre-filled message appears in the chat input, but the user must tap "Send" manually. This ensures privacy and prevents unwanted messages — the user always stays in control.
Can I use a WhatsApp Business number?
Absolutely. WhatsApp Business numbers work the same way. In fact, using a Business account is recommended because it gives you access to auto-replies, business hours, catalogs, and other professional features that improve the customer experience.
What is the difference between WhatsApp QR and SMS QR?
An SMS QR code opens the native text messaging app, while a WhatsApp QR code opens WhatsApp specifically. WhatsApp is free (uses internet instead of carrier charges), supports rich media (images, documents, voice), and is the primary messaging platform in many countries. Choose based on what your audience uses most.
