Generate an SMS QR code

Create a QR code that opens the messaging app with the number and a prepared text already in place. The recipient only has to press send, which is why it works well for check-ins, votes, callback requests and short codes.

What is an SMS QR code?

An SMS QR code encodes a phone number and a ready-made message in the SMSTO: format. Scanning it opens the messaging app with both filled in; the sender only presses send. Nothing is sent automatically - no QR code can do that, and no phone would allow it.

What it is actually used for

  • Check-in and attendance: one code per room or station, the message says which one.
  • Voting and competitions: a short code plus a fixed keyword, printed on the entry form.
  • Callback requests: on a closed shop door or a machine that needs service.
  • Parking and vending: where a short code is the payment or release channel.

Before you print it

Write the number in international format starting with the country code, for example +43 660 1234567. A national short form only works for people whose SIM is in the right country, which is exactly the group a printed poster cannot rely on.

Remember that the sender pays whatever their tariff charges, and premium short codes can be expensive. Print the cost next to the code if it is not free - it is the polite thing to do and in many places the legally required one.
