How to Create a WhatsApp Link: The wa.me and QR Code Guide

Your customer wants to reach you. But first they have to save your number, then open WhatsApp, then find you. Every extra step is another chance for them to give up and message someone else instead. A WhatsApp link solves exactly that: one tap and the customer lands straight in a chat with you — with their first sentence already typed out.
Here's the good part: this costs nothing and requires no app, no account, no approval. If you can type a line of text, you're five minutes away from having one. In this guide I'll walk through how to build the link, how to add a pre-filled message, how to turn it into a QR code, and — most importantly — where to actually put it.
What is a WhatsApp link, and why does wa.me matter for your business?
wa.me is WhatsApp's own short link format. The structure is simple:
https://wa.me/1XXXXXXXXXX
The number is your WhatsApp line in international format — country code first, no symbols. For the US and Canada the country code is 1. So if your number is (415) 555-0123, your link is:
https://wa.me/14155550123
For the UK the country code is 44, and the leading zero of the national number drops. So 07700 900123 becomes:
https://wa.me/447700900123
Anyone who taps that link goes straight into a chat with you, assuming WhatsApp is installed on their phone. Clicked from a computer, it opens in WhatsApp Web or the desktop app. Either way, the customer never has to save your number first.
The three most common mistakes when writing the number
Avoid these three and your link will work:
- Keeping the leading zero. 447700900123 is right, 4407700900123 is wrong. The zero at the start of the national number drops after the country code. (US numbers don't have this zero to begin with.)
- Using spaces, dashes, or parentheses. Digits only. Something like
+1 (415) 555-0123will not work in the link. - Adding a plus sign. wa.me links don't need the
+.
Once it's built, test it from your own phone and, if you can, from a friend's phone too. One wrong digit means nobody can reach you for months — and you won't even notice.
Creating a WhatsApp link with a pre-filled message
This is where the real power is. You can attach a ready-made message to the link. When the customer taps it, the text is already sitting in the input box — all they do is hit send.
The structure looks like this:
https://wa.me/14155550123?text=Hi,%20I'd%20like%20to%20book%20an%20appointment
That %20 stands for a space. When you write the link by hand, every space needs to become %20. Accented characters and emoji can also misbehave in some places, so keep the pre-filled text plain.
The way to do it without the hassle
If you'd rather not wrestle with %20, the WhatsApp Business app can generate a short link and a QR code from your business profile. Menu names and the location of that option change from version to version, so I won't give you a step-by-step that goes stale: look in the app's settings or business section for headings with "link" or "QR" in them.
There are also free "wa.me link generator" tools online: you type in your number and message, and it hands you a finished link. Only ever enter public information into those tools — your business number, nothing else. No customer data.
How should you word the pre-filled message?
The pre-filled message decides how the conversation starts. Written well, it makes you money. Two examples:
Weak: "Hi" You get hundreds of "hi" messages with no indication of what anyone wants, and you have to ask every single one what they need.
Strong: "Hi, I'd like to book a weekday appointment for color" The customer has told you what they want in their very first message. You can close it in a single reply.
Change the message depending on where the link lives. For the QR code in your window: "Hi, I'd like to ask about pricing." For a product page on your website: "Hi, I'd like more information about [product]." If you use a different link in each place, the first sentence of every incoming message tells you where that customer came from. It's the simplest tracking you can set up without installing a single analytics tool.
If you're struggling with the wording, the principles in How to Write WhatsApp Messages for Small Businesses apply here too.
Turning the link into a QR code
Links work in the digital world. But if your customer is standing outside your shop, they can't tap a link taped to your door. That's where the QR code comes in.
A QR code is really just your link in the shape of a square image. Whoever points their camera at it has effectively clicked the link.
How to do it:
- Build your wa.me link first, pre-filled message and all.
- Paste it into a free QR code generator, or use the QR code your WhatsApp Business profile gives you.
- Download the image at the highest resolution available. If it's going to print, a small blurry image is an unreadable image.
- Test it with at least two different phones before you print. Ordering a thousand copies and then discovering it doesn't work is an expensive lesson.
What to watch for when using QR codes
- What you write next to it matters more than the code. An empty square attracts nobody. Add a line: "Scan to book," "Scan for the menu and to order."
- Place it at human height. Too low on the door or up near the ceiling and nobody stretches out their phone for it.
- Watch for glare if you're sticking it on glass. In direct sun the camera can't read it.
- A QR code on a desktop screen is pointless. Someone sitting at a computer can just click the link. Save QR codes for printed and physical places.

Where should you put the link?
The most carefully built link is worthless if nobody sees it. The list below follows the customer's journey to finding you. Which one pays off best in your business is something you'll only learn by trying.
1. Google Business Profile
Google is usually the first place a customer finds you. Add your wa.me address anywhere your profile lets you put a link — the appointment link field, the website field, or a post. There's a step-by-step in Adding WhatsApp to Your Google Business Profile.
2. Instagram bio
The link field in your bio is the only clickable spot on your profile — consider giving it to your WhatsApp link. You might have an account that racks up likes, but likes aren't revenue. Interest that never turns into a conversation disappears. I covered this shift in detail in Why Salons Should Move from Instagram to WhatsApp.
3. Your website
A WhatsApp button that stays fixed on your site asks less of people than a contact form: no name, no email, no subject line — one tap and they're typing. You don't have to remove the form. Run both side by side for a while and see which one brings in more messages.
4. Window, door, tables, the counter
This is where QR codes belong. They work even when you're closed: someone scans the code in your window after hours, leaves a message, and you answer it in the morning.
5. Business cards and invoices
If your card only has a printed number, the customer has to type it into their contacts by hand. A QR code removes that chore. Keep printing the number too — there's always someone who can't get the scan to work.
6. Email signatures and stickers
Vehicle wraps, bags, packaging, shipping boxes. Every surface that ends up in a customer's hands is an unused ad space.
The link is up and messages are coming in — now what?
This is the part nobody talks about. Put the link everywhere and your message volume goes up. That's a good thing, with one condition: that you can answer them.
Say you put the QR code in your window and 30 new messages a day start arriving. Meanwhile you're serving customers in person. By the time you open your phone in the evening, most of those people have already gone somewhere else. In that situation the link hasn't made you money — it's just made the customers you were already losing visible.
So before you spread the link around, sort out two things:
Who answers, and when? Set up an arrangement where a first reply goes out even during your busiest hours.
What are the questions you get over and over? Pricing, opening hours, address, availability. The answers to these are always the same. Typing the same answer 20 times a day should not be your job.
This is exactly where WpAsis comes in: it connects to your existing WhatsApp line, draws on your own business information, and answers incoming messages on your behalf around the clock — taking appointments and orders as it goes. You can watch every conversation from the dashboard and step in yourself whenever you want to. That "how much do you charge?" message from the QR code gets answered while you're with a customer.
If you're wondering how to set up an automatic reply system, How to Set Up WhatsApp Auto-Replies is a good place to start.
One warning: the link is not a bulk messaging tool
A wa.me link exists so customers can reach you — not so you can blast messages at people. Sending unsolicited bulk messages can get your number restricted, and it creates real problems under GDPR and equivalent data protection rules wherever your customers live. I've gathered the risks in WhatsApp Bulk Messaging: Penalties and Risks.

Frequently Asked Questions
Does creating a wa.me link cost anything?
No, it's completely free. The wa.me link is part of WhatsApp's own infrastructure and requires no registration, payment, or approval. The moment you write your number in the correct format, the link works. Don't let "free" make you careless, though: always test it before you print it or publish it.
Can I create a wa.me link with a regular WhatsApp account?
Yes. The wa.me link doesn't care whether your account is regular WhatsApp or WhatsApp Business — it works for any number with WhatsApp installed. That said, a business account gives you extras like a business profile, a catalogue, and a short link, so if you're dealing with customers it's the more sensible choice.
Can the customer delete the pre-filled message?
Yes — the message only arrives pre-typed, it isn't locked. The customer can delete it and write their own sentence instead. That's not a flaw, it's how it should be: you're simply offering a head start. Still, since the pre-filled text sets where the conversation begins, it's worth writing carefully.
I can't keep up with all the messages coming from the QR code. What should I do?
That's a sign the link is working — but it's a bottleneck you need to fix. Start by nailing down the repeated answers to your most common questions (price, hours, address, availability), then set up something to answer them automatically. An AI assistant like WpAsis connects to your existing line and handles those repeats on your behalf, so you only focus on the conversations that genuinely need you.
Setting the link up takes five minutes. The real return shows up when you answer the incoming messages quickly and consistently. Build your wa.me link today and put it somewhere — the shop window, your Instagram bio, wherever is easiest for you.
