How to Create a WhatsApp QR Code
A WhatsApp QR code uses WhatsApp's official deep-link format (https://wa.me/) to open a direct conversation to your phone number when scanned. Unlike saving a contact first, users are taken straight to a new chat — dramatically reducing friction for customer inquiries.
Step 1 — Select WhatsApp Type: On qrcodetechy.com/generator, select the "WhatsApp" QR type. You'll see a phone number field and an optional pre-filled message field.
Step 2 — Enter Phone Number: Enter your WhatsApp phone number in international format WITHOUT the leading +. Example: for +91 98765 43210 (India), enter 919876543210. For +1 (555) 012-3456 (US), enter 15550123456. The country code is mandatory — WhatsApp cannot route messages without it.
Step 3 — Add Pre-Filled Message (Optional): Type a message that will auto-populate in the chat box when someone scans the code. Great examples: "Hi, I'd like to place an order", "I need help with my booking #", or "I saw your flyer and want to know more." Keep it under 100 characters for best display on all screen sizes. The message is URL-encoded automatically.
Step 4 — Brand Your QR Code: Upload the WhatsApp logo or your business logo. Use WhatsApp green (#25D366) as the QR dot color for instant brand recognition. This visual cue tells customers exactly what happens when they scan — no guesswork.
Step 5 — Verify the Link: Before downloading, hover over the QR preview or scan it with your phone. The URL should be in the format: https://wa.me/919876543210?text=Hello. Both WhatsApp and WhatsApp Business accounts work with the same wa.me format.
Step 6 — Deploy Strategically: Print on menus, receipts, storefronts, and packaging. Display at checkout counters for post-purchase support. Add to email signatures. For WhatsApp Business users, this QR code acts as a "Click-to-Chat" button replacement that works offline (printed materials).
Technical Standards: wa.me Deep Link Format
wa.me URL Format
Structure: https://wa.me/[phone]?text=[message]. The phone number must be in E.164 format without +, spaces, or dashes. The text parameter is percent-encoded per RFC 3986.
Platform Compatibility
wa.me links open WhatsApp on iOS, Android, and WhatsApp Web (desktop browser). If WhatsApp is not installed, users are redirected to the WhatsApp download page. Works with both personal and WhatsApp Business accounts.
WhatsApp Business API vs wa.me
wa.me is the free, official short-link format. The WhatsApp Business API is for automated messaging at scale (requires approval). For QR codes on printed materials, wa.me is the correct approach and doesn't require a Business API account.
QR Code Size for Print
A WhatsApp wa.me URL is typically 40–80 characters. This produces a compact QR code (Version 3–5). Minimum print size: 2cm × 2cm. For table tents: 4cm × 4cm. For posters: 8cm × 8cm.
