How an SMS QR code works

The code stores your number and message in the standard SMSTO format that phone cameras recognise. Scanning offers to open Messages; the person sees exactly what will be sent, and to whom, before they tap send.

Texting works on every phone without an app or data connection, which makes SMS a good fit for opt-ins, contests, votes and bookings from people who may not use WhatsApp.

SMS or WhatsApp?

In countries where almost everyone uses WhatsApp, such as India and Brazil, a WhatsApp code usually gets more replies and lets you answer with photos and catalogues. SMS is better for keyword opt-ins, for older customers and in markets where texting is still the norm, such as the US. Standard message rates may apply for the sender.

Use cases

Ways to use SMS QR codes

  • Offers and opt-ins

    “Text JOIN for 10% off” on posters, receipts and packaging.

  • Contests and giveaways

    Entries by text, with the keyword already written.

  • Votes and feedback

    Quick polls at events, in classrooms and on product displays.

  • Bookings

    Salons, tutors and clinics: “Text to book” with the service named.

  • Quotes and call-backs

    A trade’s van or flyer: “Text us a photo of the job”.

  • Out-of-hours requests

    A shop window code for orders and questions after closing time.

Best practices

Tips for SMS QR codes

  • Pre-write the keyword

    Typing a keyword correctly is where most SMS campaigns lose people.

  • Say what they’ll get

    “Text to get today’s offer” beats “Scan me”. Mention if replies are automated.

  • Respect opt-in rules

    Marketing texts usually need consent and an easy way to stop, such as replying STOP.

  • Test on both platforms

    iPhone and Android handle the message field slightly differently; check both.

Static or dynamic?

A dynamic SMS code can switch campaigns

A static code is fixed to one number and message. A dynamic code lets you change the number, keyword or message for the next campaign without reprinting, and shows how many people scanned each poster.
