Where it works well
Use the QR on product packaging, business cards, restaurant tables, event stalls, real estate flyers, and support posters where typing a number would be slow.
Phone number formatting
Use the country code without plus signs or spaces for the most reliable result. For India, a number usually begins with 91 followed by the 10-digit mobile number.
Safety checks
Scan-test the QR before printing. Confirm it opens the right chat and message. Replace the QR if the phone number changes or if the campaign message is outdated.
Review method and source trail

FAQs
Does the QR send a message automatically?
No. It opens WhatsApp with a prepared message. The user still chooses whether to send it.
Should I include the plus sign?
For wa.me links, use country code and number without the plus sign.
Can I use it on a shop poster?
Yes. Test the final poster at the actual print size.
Does it work without WhatsApp installed?
The link may open a browser prompt, but the best experience requires WhatsApp.
Can I change the message later?
Static QR codes cannot change. Generate a new QR if the message changes.
Is the QR generated locally?
Yes, the QR image is rendered in the browser.
