SMS QR Code: Create Scannable Codes That Send Text Messages (2025)

An SMS QR code is a scannable image that opens a new text message on the user's phone, pre-filled with your phone number and a message. One scan, one tap to send. No typing required.

They're ideal for marketing opt-ins, customer support lines, event RSVPs, and anywhere you want to make it effortless for someone to message you.

What Is an SMS QR Code?

An SMS QR code encodes a phone number and optional message text using the smsto: URI scheme. When scanned, the user's phone opens their default messaging app with your number and message already filled in. They just hit send.

Unlike URL QR codes that open websites, SMS codes create a direct communication channel. The user sends an actual text message to your number.

Common Uses for SMS QR Codes

Marketing Opt-Ins

Place SMS QR codes on product packaging, print ads, or in-store displays. Users scan to join your SMS marketing list by sending a keyword like "JOIN" or "SUBSCRIBE."

Customer Support

Add to product manuals, receipts, or warranty cards. Customers scan to instantly message your support team—no hunting for contact info.

Event RSVPs

Include on invitations or event posters. Guests scan and send a pre-formatted "ATTENDING" message, making tracking simple.

Feedback Collection

Post-purchase or after service, let customers send quick feedback via text. The friction is so low that response rates increase significantly.

Appointment Confirmations

Healthcare, salons, and service businesses can use SMS codes on appointment cards. Patients scan to confirm or reschedule.

How to Create an SMS QR Code

Step 1: Enter the Receiving Phone Number

Use the full international format with country code:

• US: +1 555 123 4567
• UK: +44 20 1234 5678
• Germany: +49 30 123456

Step 2: Write Your Pre-Filled Message

Craft the default message users will send. Keep it:

• Short: Under 160 characters to fit in one SMS segment
• Clear: Tell users what they're requesting or confirming
• Actionable: Use keywords for easy processing ("JOIN", "HELP", "CONFIRM")

Examples:

• "JOIN to receive weekly deals from [Brand]"
• "HELP - I need assistance with my order #"
• "CONFIRM appointment for [Date]"

Step 3: Customize the Design

Add your brand colors and logo using our SMS QR Code Generator. SMS codes are static, meaning customization won't affect functionality.

Step 4: Test Before Deploying

Critical: Scan the code with a phone that's not your own to verify:

• The correct number appears
• The pre-filled message is accurate
• The messaging app opens properly

Step 5: Download and Use

Export as:

• PNG: For digital use, email signatures, websites
• SVG: For print materials that need to scale

SMS QR Code vs Other Contact Methods

SMS has a 98% open rate compared to 20% for email (Gartner), and average response time is 90 seconds (CTIA). If you need fast, reliable communication, SMS wins.

Best Practices

Keep Messages Concise

The pre-filled message should be complete but concise. Users can edit before sending, but most won't bother if it's already perfect.

Use Clear Call-to-Actions

Tell users what scanning will do: "Scan to join our text list" or "Scan to message our support team."

Consider Two-Way Communication

Make sure someone monitors the receiving number. An SMS QR code that leads to a black hole damages trust.

Track Campaign Performance

Use unique keywords per campaign ("JOIN1", "JOIN2") to track which placements drive the most engagement.

Limitations

• Carrier charges apply: Users pay their standard SMS rates
• No direct tracking: The QR code can't track sends—you track by monitoring incoming messages
• Message length: Keep under 160 characters to avoid splitting
• Smartphone required: Feature phones may not support QR scanning

Frequently Asked Questions

Do users get charged for sending the SMS?

Yes, standard carrier messaging rates apply. The QR code only composes the message—sending uses the user's SMS plan.

Can I track how many people scan the code?

The QR code itself doesn't track scans. However, you can track incoming messages to your number. Use unique keywords per campaign to measure effectiveness.

Does it work internationally?

Yes, as long as you include the full country code. International SMS rates apply based on the sender's carrier.

Can users edit the message before sending?

Yes, the pre-filled text is editable. Users can modify it before tapping send if they want to add details.

How is this different from a phone QR code?

A phone QR code initiates a voice call. An SMS QR code opens the messaging app for text communication. Use phone for immediate conversation, SMS for asynchronous messaging.
