How does an SMS QR code work?

An SMS QR code encodes a phone number (and optional pre-filled message) using the sms: URI scheme. When scanned, it opens the phone's default SMS app with the number and message already filled in.

Do I need to include the country code?

Yes — for international compatibility, include the country code with a + sign. For example, use +1 5550001234 for a US number. This ensures the QR code works for people in any country.

Can I pre-fill the message text?

Yes. Enter your message in the optional message field and it will be pre-filled when the SMS app opens. The recipient just needs to tap Send.

Does an SMS QR code require an internet connection?

No. Unlike URL QR codes, SMS codes don't require data. They only need cellular service to send the message, making them useful in areas with limited connectivity.

Where is the best place to use an SMS QR code?

Opt-in marketing campaigns, customer support, competitions, and RSVPs are great uses. Add it to flyers, posters, or business cards where you want customers to text you directly.
