About — Free WhatsApp QR Code
A WhatsApp QR code lets anyone send you a direct WhatsApp message with a single scan, without saving your number to their contacts. It’s a particularly powerful tool for professionals, tradespeople, shops and entrepreneurs who want to make it easy for customers to get in touch.
To create your WhatsApp QR code, enter the following URL into the generator: https://wa.me/447700900123, replacing the number with yours in international format (country code first, without the +, spaces or dashes). For example, the UK mobile number 07700 900123 becomes 447700900123. To pre-fill a message, use: https://wa.me/447700900123?text=Hello%20I%20would%20like%20a%20quote
A pre-filled message is a big help for professionals: you guide the customer from the very first message, cut down on back-and-forth and understand the request straight away. A tradesperson could, for example, pre-fill “Hello, I’d like a quote for” — the customer just has to finish the sentence.
Put this QR code on your business cards, shop front, work van, flyers, menus or packaging. Unlike a plain phone number, a QR code removes typos and hesitation — the conversation starts in under 3 seconds. It can also help you measure results: by using a slightly different pre-filled message on each printed item, you can see which one brings in the most WhatsApp contacts.
Good to know: WhatsApp Business offers extra features (product catalogue, automatic messages, labels) that are especially useful for professional use. The QR code works just as well with standard WhatsApp as with WhatsApp Business — the wa.me link is universal.
How do I create a WhatsApp link with my phone number?
Use https://wa.me/ followed by your number in international format: country code, then your number without the leading 0. For example, for the UK number 07700 900123, the link is https://wa.me/447700900123; for a US number (555) 123-4567, it’s https://wa.me/15551234567. No spaces, no dashes, no +.
Can I add a pre-filled message to the QR code?
Yes, add ?text=YourMessage to the end of the wa.me link, encoding spaces as %20. Example: https://wa.me/447700900123?text=Hello%2C%20I%20would%20like%20a%20quote. The person scanning will see this message ready to send.
Does the WhatsApp QR code work without saving the number?
Yes, that’s exactly the point of a wa.me link. People can message you directly without adding you to their contacts. It makes a first business contact much smoother.
Can I use this QR code with WhatsApp Business?
Absolutely. The wa.me link works the same with standard WhatsApp and WhatsApp Business. If the number belongs to a Business account, the chat opens with your business profile.
What size should a WhatsApp QR code be on a business card?
At least 2 × 2 cm (about 0.8 inch) for reliable scanning. On a standard business card, a 2.5 × 2.5 cm (1 inch) QR code in a corner works best. Download the PDF from our generator for perfect print quality.
Step-by-step guide: create and share your WhatsApp QR code
1. Write your number in international format. Remove the leading 0 and add your country code (44 for the UK, 1 for the US, 33 for France…), with no spaces, dashes or + sign.
2. Build the wa.me link. Enter https://wa.me/ followed by your number in the generator. To pre-fill a message, add ?text= followed by your encoded text (spaces become %20).
3. Write an effective opening message. “Hello, I’d like some information about…” or “Hello, I’d like to book an appointment for…” guides the customer and helps you understand the request faster.
4. Share it everywhere customers see you. Shop window, work van, invoices, packaging, staff badges: every item becomes a direct contact channel, with no number to type.
5. Track contacts by medium. Use slightly different pre-filled messages depending on where the QR code appears (e.g. “…seen on your flyer”) to find out which one brings in the most contacts.
Use cases by industry
Building trades (plumbers, electricians, painters): on vans and business cards, the QR code lets customers ask for a quote in seconds with a ready-made message.
Hair and beauty salons: in the window or on local flyers, it makes booking easy without a phone call — something many customers appreciate.
Restaurants and food trucks: on the counter or on social media, it lets you take takeaway orders or answer questions about the daily menu.
Real estate: on “for sale” or “to let” boards, it gives people a direct line to the agent to arrange a viewing, faster than a call or a web form.
Shops using WhatsApp Business: at the till or on receipts, it leads to a business account with a built-in product catalogue, automatic opening hours and quick replies.
Best practices and mistakes to avoid
✅ Always double-check the international number format. A wrong country code or a leftover leading 0 makes the link invalid and frustrates customers.
✅ Tailor the pre-filled message to each medium. It lets you measure how well each location works and steers the conversation from the start.
✅ Switch to WhatsApp Business if you can to get automatic replies, a catalogue and message statistics — especially useful when you get a lot of scans.
❌ Don’t use a personal number that isn’t meant for business without a plan for handling incoming messages, especially after a large print run.
❌ Don’t forget to encode special characters in the message (spaces, accents), or the link may break and fail to open the conversation correctly.
❌ Don’t leave the QR code without any visual cue. Add the WhatsApp logo or a line such as “Message us on WhatsApp” so people know what to expect before they scan.
