WhatsApp QR Code: What It Is and How to Generate One

01 · Glossary

The customer QR (chat QR)

This is the QR that earns money.

• Scanning it opens a chat with your business number
• No typing, no search, no friction
• Works from any phone with WhatsApp
• The conversation it opens is a service conversation — free inside 24 hours

02 · Glossary

The device QR (linking QR)

The second QR connects software to WhatsApp.

• Scanned from WhatsApp settings to link a device
• The Business App uses it for companion mode
• Providers use a similar flow to migrate a number to the Cloud API
• It is a technical tool, not a customer-facing asset

Where customer QRs go

The chat QR works best where buying intent already exists.

• Printed on receipts, invoices, and packaging
• On tables, shelves, and storefronts
• On delivery boxes and loyalty cards
• On TV screens, posters, and social media bios

Generating and tracking

A plain wa.me QR works; a tracked QR is better.

• Wutt's QR generator builds a QR for your number
• Tracked QR codes count scans and route them into the inbox
• Print high-contrast, large QRs; blurry scans kill the funnel
• Combine with a first-message coupon to measure conversions
