How to make an SMS QR code
- Enter the number that should receive the messages, in international format (+44 7700 900123).
- Write a short message, for example “BOOK Saturday 2 people” or a keyword for your SMS system.
- Scan the preview to check your messaging app opens with the number and text.
- Print it with a line explaining what happens, such as “Scan to text us your booking”.
Field help
- Phone number
- International format works everywhere. Short codes (5–6 digits) work only in their own country.
- Message
- Optional. Most phones fill it in; a few older Android apps ignore it and open an empty message.
Ideas
Keyword opt-ins
Customers text a keyword to join offers. Make sure your SMS provider supports it and follows local consent rules.
Repair and service tags
Text a job number to the workshop for updates.
Feedback at events
A pre-filled “Feedback:” message gets more replies than a blank one.
Limits
- Normal SMS charges may apply to the sender. Mention this if you use premium short codes.
- Nothing is sent automatically; the person reviews the message first.
- For chat-style conversations, a WhatsApp code is usually a better fit in many countries.
Questions people ask
Does it work on iPhone and Android?
Yes. Both open the default messaging app with the number filled in.
Can I send to several numbers?
Group recipients are not handled consistently across phones, so the code supports one number.
