SMS still reaches everyone, including people without data or a smartphone app for your brand. An SMS QR code fills in both the recipient and the message, so joining a list, entering a competition or confirming a booking takes one scan and one tap.

We store the number in international format and use the SMSTO format, which the built-in cameras on iPhone and Android both understand. Messages never send automatically; the person always confirms.

How to create a SMS QR code

  1. Enter the receiving number

    Choose the country code and type the number in any local or international format.

  2. Write the message

    A keyword like JOIN, VOTE 3 or a booking reference works best. Keep it short.

  3. Style it

    Add your colours and a line such as "Text us to join" so people know what to expect.

  4. Download and display

    Print it on posters, counters, event screens or product inserts.

Ways to use it

  • Opt-ins and alerts. Grow an SMS list for offers, church announcements or school updates.

  • Voting and polls. Run audience votes at events with a different code for each option.

  • Bookings and confirmations. Customers text a reference or "YES" without typing it.

  • Feedback. Collect quick ratings at the counter: "Text 1–5 to rate us today".

Tips for a code that scans every time

  • Tell people about any charges. Standard SMS rates may apply to the sender.
  • Use one keyword per code so replies are easy to sort.
  • For conversations rather than one-off messages, a WhatsApp QR code is usually better.

Frequently asked questions

Does the message send automatically when scanned?

No. The phone opens a new text message with your number and text filled in, and the person taps send.

Will it work on iPhone and Android?

Yes. We use the SMSTO format that both platforms' camera apps recognise. Test with your own phone before printing.

Can I leave the message empty?

Yes. The code then just opens a blank text to your number.

How long can the message be?

We allow up to 300 characters, but shorter is better. Long messages make the code denser and harder to scan, and may be split into several SMS.

Does sending the text cost the person money?

It costs a normal SMS at their network's rate, unless you use a free short code arranged with a network operator.
