WhatsApp QR Codes: Scan to Chat. No Number Saving Required.
Create a WhatsApp QR code with pre-filled message text. Customers scan and start chatting instantly without saving your number, with full scan analytics.
Remove Every Friction Point From Customer Communication
The biggest barrier to WhatsApp-based customer communication is the number-saving step. Customers have to manually type your number, save it, and then open WhatsApp. Most do not bother. A SMLLR WhatsApp QR code eliminates this entirely. When scanned, it opens a WhatsApp chat with your number pre-loaded — and optionally, a pre-written message already filled in. The customer just hits "Send." Zero friction. Maximum conversion.
- Pre-filled opening message to guide the conversation
- No number saving required — chat opens instantly on scan
- Works for WhatsApp Business and personal accounts
- Dynamic: change the phone number destination anytime
- Track every scan with full analytics
- Ideal for restaurants, services, sales, and support
Pre-Fill the Message for Perfect Conversation Starters
The power of a SMLLR WhatsApp QR is the pre-filled message parameter. When a customer scans your table QR at a restaurant, the chat opens with "Hi! I'd like to make a reservation for tonight." When they scan a code on your real estate listing, it opens with "I'm interested in the 3BHK on Palm Street." This pre-filled context removes the customer's cognitive load and immediately signals to your team the customer's intent — making every conversation higher quality from the first message.
Dynamic Routing: Change the Number Without Reprinting
Business phone numbers change. Support managers move on. SMLLR's dynamic WhatsApp QR codes let you change the destination phone number at any time — without touching your printed materials. Update it from your dashboard, and every physical code in the field starts routing to the new number immediately. Perfect for businesses where a specific WhatsApp number handles all incoming scan-to-chat conversations.
Routing Different Codes to Different Teams
A single business can run several WhatsApp QR codes at once, each pointed at a different number or pre-filled message depending on placement. A code at the sales counter can open a chat with the sales line and a "I'd like a quote" message, while a code near the service desk opens a chat with support and a different opening line. This keeps conversations landing with the right team from the very first message, without the customer having to explain what they need.
Pre-Filled Messages in More Than One Language
For businesses serving a mixed-language customer base, the pre-filled message doesn't have to be in English. A code placed in a Tamil Nadu storefront can pre-fill a Tamil opening line; one at a Delhi outlet can pre-fill Hindi. Since each code is independently configured, you can match the opening message to the language most of that specific location's customers are comfortable with. WhatsApp QR codes pair especially well with a digital menu QR code for reservations and takeaway orders, or a UPI payment QR code for settling a bill in the same chat.

Frequently Asked Questions
How do I create a WhatsApp QR code?
In SMLLR, create a new QR code, select "WhatsApp" as the type, enter your WhatsApp phone number (with country code), and optionally add a pre-filled message. Your QR code is ready to download and print.
Can I pre-fill the WhatsApp message for customers?
Yes. SMLLR lets you specify a pre-filled message that appears in the customer's WhatsApp chat as soon as they scan. They just need to tap "Send." This is ideal for guiding the conversation from the first interaction.
Does it work with WhatsApp Business?
Yes. The WhatsApp QR code works with both personal WhatsApp and WhatsApp Business accounts. For high-volume customer communication, we recommend using WhatsApp Business or the WhatsApp Business API.
Can different QR codes route to different WhatsApp numbers?
Yes. You can create separate WhatsApp QR codes for sales, support, or different store locations, each pointing to the appropriate number and pre-filled message.
What happens outside business hours?
You can pre-fill a message that sets expectations (e.g., "We'll reply within business hours"), or route the code to a landing page with hours and an alternate contact method during off-hours.
Can I use a WhatsApp QR code without WhatsApp Business?
Yes, it works with a personal WhatsApp number too, though WhatsApp Business adds features like quick replies and a business profile that make high-volume scan-to-chat easier to manage.
Can I see how many scans turned into an actual message sent?
SMLLR tracks the scan and chat-open event; whether the customer sends the pre-filled message depends on their own action within WhatsApp, which isn't visible to SMLLR.
Can I use emojis or line breaks in the pre-filled message?
Yes. The pre-filled message supports standard WhatsApp text formatting, including emojis and line breaks, as long as it's properly URL-encoded.
Does the customer need WhatsApp installed for this to work?
Yes. If WhatsApp isn't installed on the scanning device, the link typically prompts the user to install it or opens WhatsApp Web as a fallback, depending on the device.
