How to Make an SMS QR Code

To make an SMS QR code, enter the destination phone number and the message you want pre-filled, then download the generated code. When someone scans it, their messaging app opens with the number and message already in place — they just tap send. The details are encoded directly into the QR pattern, so the code works with no service behind it and never expires.

Ways to Use an SMS QR Code

Keyword Opt-Ins

Pre-fill "JOIN" so customers text to subscribe to your list in one tap.

Quick Enquiries

Let people text a question about a product or listing without dialing.

Feedback & Reviews

Put a code on the receipt so guests can text how their visit went.

Event RSVPs

Print it on the invite so guests reply with a pre-written "YES".

Support & Service

A sticker on equipment lets customers text for help with the model pre-filled.

Promotions

Text-to-win and coupon codes get more entries when the message is ready to go.

Step-By-Step

  1. Enter the phone number the text should be sent to, with country code for international use.
  2. Write the pre-filled message — a short keyword works best, or leave it blank so people write their own.
  3. Download the QR code as PNG, JPG, or SVG. SVG stays sharp at any print size.
  4. Test it on an iPhone and an Android — confirm the number and message appear before you print.

Frequently Asked Questions

What is an SMS QR code?

An SMS QR code opens a new text message pre-filled with a phone number and, optionally, a message. When someone scans it, their messaging app opens ready to send — they just tap send. It is a fast way to collect texts, opt-ins, or enquiries.

How do I make a QR code that sends a text message?

Enter the phone number the text should go to and the message you want pre-filled. The QR code updates as you type. Download it as a PNG, JPG, or SVG and add it to a flyer, sign, or product.

Is the SMS QR code generator free?

Yes. SMS QR codes are static — the number and message are encoded directly into the pattern — so they are free forever with no watermark, no scan limit, and no expiry. No account required.

Does the person still have to press send?

Yes. For safety, phones never send a text automatically. Scanning opens the messaging app with the number and message already filled in, and the person taps send themselves. This keeps them in control and works the same on iPhone and Android.

What should I put in the pre-filled message?

A short keyword works well for opt-ins and campaigns — for example "JOIN" or "MENU". You can also leave the message blank so the person writes their own, which suits enquiry and feedback use cases.

Can I change the number or message after printing?

An SMS QR code is static, so the number and message are fixed once printed. To change them, generate and print a new code.
