WhatsApp Link (wa.me) and QR Code: How to Create Them

A WhatsApp link and a QR code are the simplest keys for a customer to start chatting with you without saving your number. One tap on the link or one scan of the QR opens the conversation, even with a message already written. This guide shows you how to create both, customize them, and use them to attract more customers.

What the wa.me link is

The official WhatsApp link format is https://wa.me/<number>, where the number is in international format with no symbols or spaces. For example, a US number: https://wa.me/15551234567. Clicking it opens WhatsApp with your chat ready to type.

The big advantage is you can prefill a message. Just add ?text= followed by the encoded text:

https://wa.me/15551234567?text=Hi,%20I%20want%20info

That way, when the customer enters the chat, the message already appears and they only have to send it. Spaces become %20, or you can use a generator that handles it for you.

How to create your link step by step

1. Take your number in international format (country code + number, without the +, without carrier leading zeros).
2. Build the base: https://wa.me/ + your number.
3. For a prefilled message, add ?text= and your text.
4. Test the link on your own phone and on a computer.

Avoid common mistakes: don't put dashes or parentheses in the number, and double-check the country code.

What a QR code is and how to make it

The QR code is the visual version of the link. Scanned with the camera, the phone opens the same chat. It's ideal for the physical world: storefronts, business cards, packaging, counters, flyers, or a restaurant table.

To create one you have two paths:

• From WhatsApp Business: the app can generate a QR for your number in settings, and even include a prefilled message.
• From a QR generator: paste your full wa.me link (message included) into any QR code generator and download the image.

Print the QR at a good size with clear contrast, and add a call to action: "Scan me and message us on WhatsApp."

Where to use your links and QR codes

The key is to seed them at every touchpoint:

• On your website, as a button.
• On your social media: Instagram bio, posts, ads.
• On print material: cards, invoices, packaging.
• In your physical store: register, tables, window.
• In ad campaigns that go straight to chat (the well-known click-to-WhatsApp ads).

The step that multiplies results

Creating the link is only the beginning. If you distribute several QR codes and links across channels, you'll want to know which brings the most customers. Here a WhatsApp CRM helps: with Omnifox you can use a different prefilled message per channel (say, one text for the storefront QR and another for the Instagram link) to identify where each conversation comes from. Everyone who writes lands in your shared inbox, gets logged as a contact, and can be handled by several agents or by an AI agent instantly.

That way, your links and QR codes stop being simple shortcuts and become measurable lead sources.

Final best practices

• Keep the prefilled message short and natural.
• Don't change your number once it's printed on physical material; you'd lose all those QR codes.
• Periodically check that the link still works.
• Always pair the QR with a phrase inviting people to scan.

Creative ways to use your QR

The WhatsApp QR is more versatile than it looks. A few ideas that work:

• On product packaging: a QR that says "Questions about use? Message us" improves the post-sale experience and reduces negative reviews.
• At events and trade shows: a large QR at your booth turns curious passersby into contacts without asking them to type your number.
• On the invoice or receipt: invite the customer to leave feedback or reorder by chat.
• On delivery vehicles: a visible QR on the bike or van captures customers as you drive around.

The idea is to be present exactly where the customer intends to reach you, with the least effort on their part.

Link, QR, and ad campaigns

If you run digital ads, click-to-WhatsApp links work on the same logic as your wa.me link but optimized inside the ad platforms. Combining physical QR codes, social links, and paid ads gives you full coverage: you capture the person who sees you on the street, the one who follows you on social media, and the one who discovers your ad. The essential thing is that all those doors lead to a single, organized place where no conversation gets lost.

Wrapping up

The wa.me link and QR code are free, quick to create, and hugely useful for opening conversations. Build your link with the correct number, add a prefilled message, generate the QR, and place them at every touchpoint. And if you want to measure which channel performs best and handle each chat in an organized way, connect everything to Omnifox to turn every scan into a sale.
