How SMS QR Codes Work
An SMS QR code encodes a special link that opens the default messaging app on the user's phone. The phone number is pre-filled, and you can optionally include a pre-written message. The user reviews the message and taps send — it works with iMessage, Google Messages, and any SMS app.
How to Create an SMS QR Code
- Enter the phone number that should receive the text message, including country code.
- Write a pre-filled message (optional) — this appears in the text field, ready to send.
- Download your QR code and place it wherever you want people to text you.
Where to Use SMS QR Codes
- Opt-in campaigns — "Scan to text JOIN to 12345" for mailing list signups
- Customer support — "Scan to text us" with a pre-filled "Help with order #" message
- Two-factor authentication setup — link to SMS verification numbers
- Voting and polls — "Scan to text your vote" for audience participation
- Appointment reminders — "Scan to confirm your appointment"
Frequently Asked Questions
Can I pre-fill the text message?
Yes. Enter your desired message in the optional message field. When scanned, the user's messaging app opens with the number and message already filled in. They can edit it before sending or just tap send.
Does this work with iMessage?
Yes. The SMS QR code uses the standard sms: protocol, which opens whatever messaging app the user has as their default — iMessage on iPhone, Google Messages on Android, or any other SMS app.
Is there a character limit for the pre-filled message?
The QR code can hold the message, but keep it short for best results — under 160 characters mirrors a standard SMS. Longer messages may be split into multiple texts by the carrier.
