# TCPA Express Written Consent Requirements for Automated SMS Gateways

Legal and technical blueprint for Telephone Consumer Protection Act (TCPA) compliance. Maintain verifiable digital consent audit trails to stop litigation.

Key Takeaway & Executive Summary

TCPA statutory damages range from $500 to $1,500 per unsolicited SMS. Build auditable consent logs with timestamps, IP addresses, and form disclosures.

The Telephone Consumer Protection Act (TCPA) provides severe civil penalties for automated messaging dispatched without proper express written consent. Class action lawsuits routinely target software platforms with inadequate opt-in documentation. This guide details how to build an audit-proof consent architecture.

When a user inputs their phone number, log an immutable audit record containing:

1. Timestamp in UTC with millisecond precision.
2. User IP address and user-agent string.
3. Exact disclosure text displayed above the submit button.
4. Unchecked checkbox state: Consent checkboxes cannot be pre-checked.
5. Screenshot or DOM snapshot of the rendered form.

## Frequently Asked Questions • Telecom Regulations & A2P 10DLC

Can I import a phone number list from a third-party partner?

No. TCPA express written consent is strictly non-transferable. You must collect direct consent for your specific corporate entity.
