Legal & Compliance Guide
SMS Marketing Regulations & Opt-In Rules
- Ensure compliance with local telecommunications laws (TCPA in the US, GDPR in the EU). Users must explicitly tap "Send" in their SMS app to transmit the message.
- Clearly state in your promotional signage that standard message and data rates may apply according to the user’s mobile carrier plan.
- Uses the widely supported SMSTO: format (smsto:number:message), not the sms: link defined in RFC 5724.
Frequently Asked Questions
Does the user get charged automatically when scanning?
No. The user still has to tap "Send" in their messaging app. It simply pre-fills the message and phone number.
