SMS QR Code Generator

An SMS QR code opens a pre-addressed text message on the user's phone when scanned. You can pre-fill both the recipient number and the message body. This is one of the most effective tools for text message opt-in campaigns, appointment bookings, and customer inquiries — the barrier to texting is lower than calling, and a QR code removes even the step of entering your number.

SMS QR codes for opt-in campaigns

Text message marketing has some of the highest open rates of any channel — over 95%. But building a text list requires consent. A QR code that pre-fills a text to your short code with an opt-in keyword is the most frictionless way to collect SMS subscribers in a physical context. Display it at your point of sale, on event signage, or in a print ad with a label like "Text JOIN to subscribe" — the QR code does the addressing for them.

For appointment-based businesses — salons, clinics, personal trainers — a QR code that opens a pre-filled text to your booking number reduces no-show rates because customers who have already engaged via text are more committed.

How to format an SMS QR code

The sms: URI format is: sms:+[number]?body=Your+message+here. For example: sms:+15551234567?body=Hi!+I'd+like+to+book+an+appointment. The phone's native messages app opens with the number and message pre-filled — the user just taps Send. On iOS, use sms:+15551234567&body=message. The exact format varies slightly between Android and iOS but modern implementations handle both.
