WhatsApp is the preferred communication channel for millions of people. For many customers it is easier to send a message than to call or fill in a form. A WhatsApp QR code removes all friction: the customer scans the code and a conversation with you opens, with your number already in place and even a message typed. No saving contacts, no copying numbers. In this article we explain how to create one and how to get the most out of it.
How it works
WhatsApp lets you open a chat through a link like this:
https://wa.me/15551234567?text=Hi,%20I%20would%20like%20information
The QR code stores that link. When scanned, the phone opens WhatsApp (or WhatsApp Business) with a new conversation to your number and the predefined text in the message box. The customer just taps Send.
How to create your WhatsApp QR code
- Open the QRcrea QR code generator and choose the WhatsApp type.
- Type your number with the country code, without the “+” sign, spaces or hyphens. For example, for the US 15551234567.
- Add a predefined message (optional, but highly recommended).
- Customize the design: WhatsApp green or your brand colors, and an icon in the center.
- Test it from another phone to check the chat opens with your number.
- Download it and add it to your materials.
How to write a good predefined message
The predefined message helps the customer take the first step and tells you where they came from. Some examples:
- “Hi, I saw your poster and want to book a table.”
- “Hi, I’m interested in the product from the September flyer.”
- “Hi, I’d like a quote for a renovation.”
- “Hi, I have a question about my order number…”
Tip: create a different code for each medium (poster, flyer, packaging) with a different message. That way you will know which channel brings you the most conversations.
Ideas for using a WhatsApp QR code
Restaurants and delivery
On the menu, the door or delivery bags, for orders and bookings.
Shops
In the window, on product labels or on the receipt for questions and after-sales support.
Professional services
Plumbers, electricians, hair salons, clinics or academies can put it on cards, vehicles and flyers for booking appointments.
Real estate
On “For sale” or “For rent” signs, with a message that includes the property reference.
Events
On posters and tickets to answer attendees’ questions.
WhatsApp Business: better customer service
If you use the QR code for your business, we recommend WhatsApp Business, the free app for companies. It lets you:
- Set up an automatic greeting message.
- Define an away message outside business hours.
- Create quick replies for frequently asked questions.
- Show a product catalog.
- Organize conversations with labels.
A customer who writes after scanning a code expects a fast reply. If you cannot answer right away, the automatic message will tell them when you will.
Best practices
| Do | Avoid |
|---|---|
| State your opening hours | Leaving messages unanswered for days |
| Use a clear predefined message | Long or confusing predefined messages |
| Add a call to action next to the code | A code with no explanation |
| Test the code before printing | Numbers without a country code |
Privacy
When you publish a WhatsApp QR code, your number will be visible to anyone who messages you. If you do not want to use your personal number, use a dedicated business number with WhatsApp Business.
Examples by industry
A restaurant can print a code on its takeaway bags with the message “Hi, I’d like to repeat my order”. A language school can put a code on its flyers with “Hi, I’d like information about adult English courses”. A real estate agency can include a code on each sign with the property reference already typed, so it knows instantly which listing people are asking about. A garage can put it on the invoice with “Hi, I’d like to book my next service”. In every case, the predefined message saves the customer time and gives you immediate context to reply better.
How to reply to messages that arrive via QR
Someone who writes after scanning a code is at a moment of high interest, and that interest cools quickly. Reply within minutes if you can, or set an automatic message saying when you will. Use quick replies for the most common questions (opening hours, prices, location) and end each conversation with a clear next step: book, buy, visit. That way the code does not just generate messages, it generates customers.
Frequently asked questions
Does it work if the customer has not saved my number?
Yes. That is exactly the advantage: the chat opens without having to save the contact.
Does it work on a computer?
If scanned with a phone, it opens in the app. If someone clicks the link on a computer, WhatsApp Web or the desktop app will open.
Can I change the message later?
If the code is static, no: you will need to create a new one. That is why it is worth choosing the message carefully from the start.
Does it work for groups?
For groups you use the group invite link, which you can also turn into a URL QR code.
