WhatsApp is the front desk for a huge share of small businesses. A QR code that opens wa.me with a prefilled “I saw your poster” message removes the friction of asking for a number and waiting.
Enter the number in international format without plus signs or leading zeros. Add a short greeting so you can tag those chats. Place the code on packaging, Instagram bio printouts, and delivery bags - anywhere a customer already has the phone in hand.
FAQ: WhatsApp QR Code Generator
Does the visitor need my number saved?
No. The wa.me link opens a chat thread. They still need WhatsApp installed.
What if they do not have WhatsApp?
The link will send them to the WhatsApp website or store. Offer a phone or email QR as a fallback on the same poster if that audience matters.
