# Free WhatsApp QR Code Generator

Start a WhatsApp conversation with a single scan. Pre-fill your phone number and an optional message so customers can reach you instantly.

A WhatsApp QR code uses wa.me links to open a direct chat with your number — no need for the customer to save your contact first. They scan, the chat opens, and they send. It's the fastest way to start a WhatsApp conversation from a physical surface.

Popular uses include restaurant tables, product inserts, storefront stickers, business cards, event badges, and customer support signage. Works with both WhatsApp personal accounts and WhatsApp Business, making it versatile for freelancers, small businesses, and enterprises alike.

The QR code is generated entirely in your browser — your phone number and pre-filled message are never sent to any server. Customize colors and branding, then download in PNG, SVG, or WebP.

For businesses in markets where WhatsApp is the default messaging channel — much of Latin America, India, Southeast Asia, Africa, and southern Europe — a WhatsApp QR code often outperforms a phone number or email address on the same sign. Customers reach you in the app they already live in, and the conversation has a written record both sides can refer back to.

The pre-filled message is worth thinking about, because it removes the blank-screen problem. "Hi! I'd like to book a table" on a restaurant window, "I have a question about my order" on a packaging insert, or "Requesting a quote" on a van decal means the customer only has to press send. It also tells you instantly which surface the conversation came from.

A static WhatsApp QR code encodes the wa.me link permanently — fine while your number never changes. If the code is going on packaging, vehicle wraps, or anything with a long print life, consider pointing it at a reRoute dynamic link instead: if you switch to a new number or move support to a different channel, you update the destination once and every printed code keeps working.

Dynamic links also add measurement: scan counts, countries, devices, and times of day tell you which placements start conversations and which are wasted print. You can even use time rules to send after-hours scans to a different destination — a contact form or booking page — instead of a chat nobody will answer until morning.

## How to make one

1. **Enter your WhatsApp number** — Type your phone number with the full country code, without the + sign or spaces (e.g., 15551234567). This is the number people will chat with.
2. **Add a pre-filled message (optional)** — Enter a default message that appears in the chat input when someone opens the conversation — great for order inquiries or support requests.
3. **Customize the design** — Choose WhatsApp green or your brand colors, pick a dot style, and add your logo to the center.
4. **Download and display** — Download as PNG, SVG, or WebP. Place the QR code on tables, packaging, business cards, or storefronts.

## Why use this

- **Chat Without Saving a Contact** — The wa.me link opens a conversation with your number directly — customers skip the save-contact step entirely and just start typing.
- **Pre-Filled Message Included** — Set a default message so customers only press send. It lowers the barrier to writing and tells you which sign or insert the chat came from.
- **Works With Personal and Business Accounts** — Any WhatsApp number works — regular or WhatsApp Business. No API setup, no approval process, just your number with country code.
- **Private, Free, Client-Side** — Your phone number and message are encoded entirely in your browser and never sent to a server. Generate unlimited codes at no cost.
- **Reprint-Proof With Dynamic Links** — Point the code at a reRoute dynamic link and you can change the number or destination later — printed packaging and signage keep working.
- **See Which Placements Start Chats** — With a dynamic link in front, scan analytics show which tables, packages, or posters actually drive conversations.

## Where to Use a WhatsApp QR Code

Storefronts and restaurant windows use WhatsApp QR codes for reservations and questions — "Scan to book a table" converts passers-by even when the shop is closed, because the message waits for you.

E-commerce brands put the code on packaging inserts for support: a customer with a problem lands in a chat instead of hunting for an email address, and resolved-in-chat problems rarely become negative reviews.

Service businesses — salons, clinics, tutors, repair shops — use it for bookings. A code on the business card or van with "Requesting a quote" pre-filled turns sightings into inquiries with one scan and one tap.

Market stalls and small vendors in WhatsApp-first markets take orders through a code taped to the stall. It is the lightest possible ordering system: no website, no app, just a chat.

Event organizers and communities print codes on badges and flyers so attendees can reach the help desk or join the conversation without typing a number.

## Frequently asked questions

### How does a WhatsApp QR code work?

The QR code contains a wa.me link with your phone number. When scanned, it opens WhatsApp directly to a new chat with you — the sender doesn't need to save your number first.

### Do I need a WhatsApp Business account?

No. The QR code works with both regular WhatsApp and WhatsApp Business accounts. Just enter your phone number with the country code.

### Can I pre-fill a message?

Yes. You can set a default message that appears in the chat input when the user opens the conversation. This is great for order inquiries, support requests, or booking confirmations.

### What phone number format should I use?

Enter your full international number including country code, without the + sign or dashes (e.g., 15551234567). The generator formats it automatically.

### Where should I use a WhatsApp QR code?

Restaurant tables, product packaging, business cards, storefronts, event badges, and social media profiles are all popular placements.

### Does the person scanning need WhatsApp installed?

Yes — the wa.me link opens the WhatsApp app if installed, or WhatsApp Web in the browser. Someone without a WhatsApp account will be prompted to sign up, so in WhatsApp-first markets this is rarely an issue.

### Can I change the phone number after printing the QR code?

Not with a static code — the wa.me link is encoded permanently. If you point the code at a reRoute dynamic link instead, you can update the number or destination anytime and every printed code keeps working.

### Will customers see my phone number?

Yes. Opening the chat reveals the number behind the wa.me link, just as messaging any contact would. If you want to keep a personal number private, use a dedicated business number or a WhatsApp Business account.

### Does it work for international customers?

Yes. Because the number is encoded with its full country code, the wa.me link works from anywhere in the world — a scanner in another country reaches the same chat with no extra dialing prefixes.

### Can I track how many people scan my WhatsApp QR code?

A static code cannot be tracked — the scan goes straight to WhatsApp. Route the code through a reRoute dynamic link and you get scan analytics (count, location, device, time), plus options like time-based routing to send after-hours scans to a booking page instead of an unanswered chat.
