SMS QR Codes: Scan to Open a Pre-Filled Text Message

Texting a business often means saving an unfamiliar number first, then typing out a message from nothing. An SMS QR code removes both steps: scan it, and the phone's messaging app opens with the number and a message already filled in, ready to send.

What actually happens when you scan it

An SMS QR code opens the phone's default messaging app (iMessage, Google Messages, or whatever's installed) with a new text pre-addressed to the number you set, and - if you included one - the message already typed out. The person scanning still taps send themselves; nothing goes out automatically.

What goes on the card

  • Phone number - where the text goes
  • Message - optional, useful for something specific like "TEXT to enter" or "STOP to unsubscribe" style keywords, or just a simple opener like "I'd like to book an appointment"

Where it's actually useful

A storefront sign for a business that takes appointment requests by text instead of a phone call, a promo flyer with a keyword-style opt-in ("Text JOIN to sign up"), a real estate yard sign where scanning starts a text asking about the listing, an event badge for a quick "add me to the list" text. Anywhere a phone number would be printed with the expectation that someone texts it, an SMS QR code removes the step of saving the number and typing the first message.

SMS vs WhatsApp QR codes

They look similar but reach different apps: an SMS QR code opens the phone's native texting app over the regular cellular network, while a WhatsApp QR code opens WhatsApp specifically. Use SMS when you can't assume the person has WhatsApp installed; use WhatsApp when your audience already lives there.

Getting started

SMS is one of 19 QR code types available after you sign up free - enter the number and, optionally, a message, and it's ready to print.

Common questions

Does an SMS QR code send the text automatically?

No. It opens the phone's messaging app with the number and message pre-filled - the person scanning still taps send themselves.

What information goes into an SMS QR code?

A phone number, and optionally a pre-filled message - useful for a specific opener or a keyword-style prompt like "TEXT to enter" or "STOP to unsubscribe."

Which messaging app does an SMS QR code open?

Whatever's set as the phone's default messaging app - iMessage, Google Messages, or another installed app.

What's the difference between an SMS QR code and a WhatsApp QR code?

An SMS QR code opens the phone's native texting app over the regular cellular network. A [WhatsApp QR code](/blog/whatsapp-qr-code-click-to-chat) opens WhatsApp specifically - use SMS when you can't assume the person has WhatsApp installed.
