SMS QR Code Generator

An SMS QR code opens the native messaging app with a phone number and an optional pre-filled message. One scan drops the user into a compose screen — ready to send with a single tap. It works on iOS and Android without any extra app.

Built on the sms: URI scheme — natively supported by iOS and Android, so no third-party scanner or app install is required.

Common Use Cases

Opt-in Campaigns

Pre-fill your subscription keyword on posters or ads so users scan and just tap Send to join.

Text-to-Vote

Encode a vote code so the audience texts their choice in seconds during events and broadcasts.

Support Hotlines

Make it effortless for customers to text a specific support number with the topic already filled in.

How to Create an SMS QR Code

Enter the Phone Number

Type the number that will receive the message. Use international format (e.g., +1 555 000 0000) for compatibility across different countries and mobile carriers.

Add a Pre-filled Message (Optional)

Enter the text that appears in the compose field when the user scans the code. This can be a keyword for an opt-in campaign, a short prompt, or any text the user should send.

Customize & Download

Open Customize to change colors, select a dot style, or embed a logo. Then download as PNG, SVG, or JPG, or copy the QR code straight to your clipboard.

Nothing is sent automatically. Scanning only opens the messaging app with the number and text pre-filled — the user taps Send when ready.

Frequently Asked Questions

Does the message send automatically after scanning?

No. Scanning opens the messaging app with the number and message pre-filled. The user must tap Send to transmit the message. No SMS is sent without a deliberate action.

What phone number format should I use?

Use international format — country code followed by the number, with no spaces or dashes (e.g., +12125550000). This works consistently across all countries and mobile carriers.

Which messaging apps are supported?

The sms: URI opens the default SMS app — Apple Messages on iOS and Google Messages (or the carrier's app) on Android. All mainstream SMS apps support the sms: scheme.

Can I use this for WhatsApp or other apps?

This tool generates standard SMS QR codes that open the native messaging app, not third-party apps. WhatsApp uses its own deep link (https://wa.me/...), which a URL QR code can handle instead.

Is there a message length limit?

A standard SMS is 160 characters; longer messages split into multiple parts. Keep the pre-filled text concise for a clean, easily scannable code — the generator shows a character count to help.

How do I collect responses sent to this number?

Responses go directly to the phone number you entered. To manage opt-ins or replies at scale, connect that number to an SMS platform or API service that handles inbound message routing.
