How a WhatsApp QR code works

A WhatsApp QR code encodes a wa.me deep link — for example https://wa.me/14155550100?text=Hi. When someone scans it, their phone opens a WhatsApp chat to your number with the message pre-filled, ready to send in one tap. It is the fastest way to turn a poster, flyer, or business card into a live conversation.

Where WhatsApp QR codes work best

  • Storefronts and restaurants — "Scan to order on WhatsApp" on the door or table.
  • Flyers and posters — turn print into a chat; see our QR poster guide.
  • Business cards — pair it with a vCard QR for contact details.

Want to track scans or change the number later?

This is a static code — it always points at the number baked in. For scan analytics or an editable destination, create a dynamic QR code pointing at your wa.me link. Full walkthrough in our guide to creating a WhatsApp QR code.

Need trackable QR codes too?

Create dynamic QR codes with real-time scan analytics — editable after printing.

Frequently asked questions

How does a WhatsApp QR code work?▾
It encodes a wa.me link with your phone number in international format. Scanning it opens a WhatsApp chat to your number, with your pre-filled message ready to send.
What number format do I use?▾
Use the full international format with country code and no plus, spaces, or dashes — the tool strips those automatically. Example: 14155550100 for a US number.
Can I pre-fill a message?▾
Yes. Whatever you type in the message field is pre-filled in the chat when someone scans, so they only need to tap send.
Can I track scans of a WhatsApp QR code?▾
Not with this static code. For scan analytics, create a dynamic URL QR that points at your wa.me link — Scanely tracks every scan and lets you edit the number later.
