Open a WhatsApp Chat With a Scan
A WhatsApp QR code encodes a direct chat link to a specific number. Scanning it opens WhatsApp straight to a conversation with you or your business — the person doesn't need to save your number in their contacts first, look it up, or type it in manually.
Enter a number below in international format (country code, digits only, no spaces or symbols) and optionally add a pre-filled message that appears already typed in the chat box. The code is built entirely in your browser from a standard wa.me link — nothing you enter is uploaded or stored.
Business Usage
Customer Support
Print the code on a receipt, invoice, or packaging insert so a customer can start a support chat without hunting down a phone number.
Storefront Click-to-Chat
A window decal or counter card lets a passerby message the business directly, even outside opening hours.
Order & Delivery Updates
Attach the code to a shipping label so a customer can message about their order in one scan.
Marketing Usage
Campaign Ads
A print or social ad with a WhatsApp QR code turns a passive viewer into a direct conversation, no landing page required.
Pre-Filled Messages
Set an optional starting message — like "I saw your ad and want to know more" — so the chat opens with context already typed in.
Good to Know Before You Print It
Anyone who scans the code can start messaging that number directly — use a number you're comfortable receiving messages on, such as a dedicated business line rather than a personal phone.
Leave off the leading "+" and any spaces or dashes in the number — just the country code followed by the rest of the digits.
The QR code works whether the number is registered for personal WhatsApp or WhatsApp Business — the behavior on scan is the same either way.
