How to Make a WhatsApp QR Code
A WhatsApp QR code turns a printed sign into a conversation. One scan opens a chat with your number, optionally with a message already typed, so the customer only has to press send. You can do all of this free at liveqr.codes — no signup needed for a static code, and a one-time $1.99 upgrade unlocks unlimited dynamic codes with scan analytics.
Steps
- Write your number in international format — Use the country code with no plus sign, spaces, or dashes — for example 393331234567 for an Italian mobile. Wrong formatting is the most common reason these codes fail.
- Draft a prefilled message — Short, specific openers work best: "Hi, I would like a quote for..." or "Table for two tonight?". It removes hesitation and tells you which sign the person scanned.
- Generate the code — Choose the WhatsApp type, enter the number and message, and the generator builds the wa.me link for you.
- Use a different message per location — Give each sign, flyer, or product insert its own opener so incoming chats reveal the source without any tracking software.
- Test from a phone that has never messaged you — Confirm the chat opens with the right number and the message text appears exactly as written, including accents and emoji.
Pro tips
- Never include a leading + or 00 in the number
- Keep prefilled messages under about 120 characters
- Add opening hours next to the code so people know when to expect a reply
Frequently asked questions
Do I need WhatsApp Business?
No, a personal number works. WhatsApp Business adds away messages, labels, and a catalogue, which help if the code drives real volume.
Can the message be edited by the sender?
Yes. The prefilled text is a draft — the person can change it before sending, and nothing is sent automatically.
Does it work on desktop?
Yes. Scanning from a laptop camera or opening the link on desktop hands off to WhatsApp Web.
