QR Code for SMS: Let People Text You in One Scan

The easiest way to turn a passerby into a conversation.

Most customers would rather text than call — but typing out a phone number from a sign is friction most people skip. An SMS QR code removes it entirely: one scan opens the messaging app with your number already filled in and a message ready to send. The customer taps send, and you have a conversation.

For businesses that take bookings, orders, support questions or feedback by text, this is one of the highest-converting QR codes you can print. It costs nothing and works on every modern phone.

How an SMS QR Code Works

An SMS QR code stores a short instruction in the universal SMSTO: format — a phone number plus an optional message. When scanned, the phone opens its messaging app with both pre-filled. Nothing is sent automatically: the user sees the message and taps send themselves. That consent step is exactly why SMS codes feel safe rather than spammy.

The format is recognized by both iPhone and Android cameras with no app needed, which is why SMS codes work for walk-in customers of every age.

Use our free QR code generator — it runs entirely in your browser:

  1. Open the SMS tab and enter your business phone number, including the country code.
  2. Write a short pre-filled message — for example "Hi, I'd like to book an appointment" or "Hi, I have a question about your menu." Keep it under 160 characters for the most reliable behavior across phones.
  3. Download the code. PNG for screens and social posts, SVG for printed signs — SVG stays sharp at any size.

Test it with an iPhone and an Android before printing. Confirm the number and message appear correctly in the messaging app on both.

Where SMS QR Codes Win

Write a Message People Actually Send

The pre-filled message decides whether the scan becomes a conversation. Good messages are short, specific, and easy to say yes to:

Avoid long messages, jargon, or anything that looks like marketing copy. The customer should feel they are starting a normal text conversation, not submitting a form.

Frequently Asked Questions

How does an SMS QR code work?

Scanning an SMS QR code opens the phone's messaging app with your number pre-filled and an optional pre-written message. The user just taps send. No number typing, no searching for your contact.

Do SMS QR codes work on iPhone and Android?

Yes. The SMSTO: format is recognized by both iPhone and Android cameras. The message app opens with the number and text ready — the user confirms before anything is sent, so nothing happens without their tap.

Can I pre-write the message in an SMS QR code?

Yes. You can include a pre-written message such as "Hi, I'd like to book an appointment" so the customer only has to tap send. Keep it short — under 160 characters works most reliably across phones.

Is an SMS QR code free to make?

Yes. Static SMS QR codes are free to generate and never expire. The only costs are printing, and the customer's normal text messaging rates when they send the message.
