How does a WhatsApp QR code work?

A WhatsApp QR code encodes a wa.me link with your phone number and an optional pre-filled message. When scanned, it opens WhatsApp and starts a conversation — no need for the scanner to save your number first.

Do I need to include the country code?

Yes. Include your full international phone number with the country code (e.g., +1 for USA, +44 for UK). Do not include the leading zero used in some countries for local dialing.

Can I pre-fill a message?

Yes! You can add a default message that will appear in the chat input when someone scans your QR code. This is great for businesses who want to collect specific inquiries.

Does WhatsApp have to be installed?

The person scanning the QR code needs WhatsApp installed on their device. The link will open the WhatsApp app directly if installed, or redirect to the app store if not.

Can I use this for a business account?

Yes, WhatsApp QR codes work with both personal and WhatsApp Business accounts. It's a great way to get customers to contact you quickly from print materials or your website.
