When to use this sign
This sign helps customers start a conversation without saving a number first. Use it at a counter or for enquiries if you actively monitor that contact channel.
It does not create bookings, orders or automated replies. CartelExprés receives neither the message nor a record of the people who scan.
How to make your whatsapp qr sign
Use a number registered with WhatsApp. Nine digits without a prefix are interpreted as Spanish; include + or 00 and the country code for another country. A prefilled message is optional and never sent by the tool.
- Optionally add your business name.
- Enter the number you use for enquiries.
- Write a visible invitation and an optional prefilled chat message.
- Test the QR on another device, choose a style and download.
Printing and sharing tips
Keep the code square and preserve its white border. The phone number is also printed for visitors who prefer to type it.
Check that the scan opens the correct account and that the prefilled message contains no private information you do not want to share.
The number must be registered with WhatsApp. A prefilled message is prepared in the chat, but the person scanning decides whether to send it.
Frequently asked questions
Can a WhatsApp number include spaces or hyphens?
Yes. Common separators are removed for the link while the visible number keeps your formatting.
Is the prefilled message sent when someone scans?
No. It is prepared in the chat. The person scanning can edit it or choose not to send it.
Do I need WhatsApp Business or an API?
No API or automation is involved. The link uses a number registered with WhatsApp.
