Free WhatsApp QR code — customers message you in one scan

Dictating a number, saving it, opening WhatsApp, typing a first message: every step loses people. The WhatsApp QR code reduces it all to one gesture — a scan opens the conversation with a ready-made message. Generated locally, no account, never expires.

How it works: the wa.me link

The code encodes a wa.me link — WhatsApp’s official format for opening a conversation:

  • International-format number — country code required, no “+”, spaces or dashes (14155552671, 33612345678);
  • Pre-filled message — the text that appears in the input field: “Hi, I’d like a quote for…”;
  • Nothing is sent without a tap — the scan prepares the message, the user decides. They can edit the text before sending.

No intermediary server: the code contains the direct link. It will work as long as WhatsApp exists and your number stays active.

Use cases

  • Storefront support — “Questions? Scan us” on the shop door: customers write even when you’re busy, you reply when you can.
  • Table ordering — on the restaurant table tent, one code per table with a pre-filled “Table 12: …” message for orders or service requests.
  • Product support — on packaging or manuals, with the product reference already in the message: you know which model it’s about before you even answer.
  • Resumés and applications — a code at the bottom of a CV, “Available for an interview”: recruiters reach you without hunting for your number.

Create the code in 3 steps

  1. Open the generator — “WhatsApp” mode is already selected if you arrive from this page.
  2. Enter the number and message — international-format number, short action-oriented message.
  3. Export — PNG up to 3000 px or SVG, then test the printed code from a real phone.

Precautions with a public number

  • Don’t use your personal number — a code displayed in a window or online broadcasts your number to the world. Use a dedicated business number (a separate SIM is enough).
  • Spam is possible — the pre-filled message filters a little, but anyone with the number can write. WhatsApp lets you block; be ready to.
  • WhatsApp required on the customer’s side — without the app installed, the link goes nowhere. For a broad audience, also print the number in plain text.

Frequently asked questions

Does the recipient need my number in their contacts?

No. The wa.me link opens a conversation directly, without the number being saved to the address book. The person scans, taps send, and the chat begins.

Is the message sent automatically when scanned?

No — and that’s reassuring. The scan only opens WhatsApp with the pre-filled message: nothing is sent until the user taps “Send”. They can also edit the text before sending.

What number format should I use?

The full international format, without the leading “+”, spaces or dashes: for example 33612345678 for a French mobile, 14155552671 for a US number. The country code is required.

Does the WhatsApp QR code expire?

Never. It’s a static code containing a simple wa.me link: as long as your WhatsApp number stays active, the printed code will work — no account or subscription on our side.
