SMS QR Code Generator

Best use cases

• Text-to-join prompts, customer support signs, appointment flows, and local campaigns.
• Event check-ins where guests send a keyword.
• Printed materials that should start a text conversation quickly.

Fields to verify

• Use a complete phone number and a short prefilled message.
• Avoid message text that could be misunderstood without context.
• Confirm the recipient can receive texts from the intended audience.

Scan quality checks

SMS QR code behavior can vary across devices and carriers. Test with the phones most likely to scan the final code.

Keep the code high contrast, leave a clear quiet margin, and test the exported PNG on the devices and printed size people will actually use.

Privacy and payload safety

The phone number and message text are encoded in the QR code, so only use numbers and message content meant for public scanning.

PlanetToolbox builds the QR payload in the browser. Anyone who scans the final code can read or use what is encoded inside it.
