What Is TCPA Compliance? TCPA SMS Requirements (2026)

What Is the TCPA?

The Telephone Consumer Protection Act (TCPA) is a federal law enacted in 1991 that restricts telemarketing calls, auto-dialed calls, prerecorded calls, text messages, and unsolicited faxes. For businesses sending SMS messages, TCPA compliance is not optional—it's a legal requirement.

Why TCPA Compliance Matters in 2026

With the explosive growth of SMS marketing, regulators and courts have become increasingly aggressive in enforcing TCPA violations. In 2025 alone, TCPA-related lawsuits resulted in over $2.1 billion in settlements and judgments.

The Cost of Non-Compliance

$500 per violation for negligent violations
$1,500 per violation for willful violations (treble damages)
Class action lawsuits that can reach millions of dollars
Carrier blocking of your business phone numbers

Key TCPA Requirements for SMS Marketing

1. Prior Express Written Consent

Before sending any marketing text message, you must obtain prior express written consent from the recipient. This consent must:

Be in writing (electronic signatures count)
Clearly authorize the specific type of messages
Include the phone number to receive messages
Not be a condition of purchase

2. Clear Disclosure

Your consent form must include:

The identity of the business sending messages
That consent is for marketing/promotional messages
The approximate frequency of messages
That message and data rates may apply
How to opt out (e.g., "Reply STOP to unsubscribe")

3. Opt-Out Mechanism

You must provide a clear and easy way for recipients to revoke consent at any time. The most common method is responding "STOP" to any message.

4. Record Keeping

Maintain records of consent for at least 4 years (the TCPA statute of limitations). These records should include:

The exact consent language shown
Timestamp of consent
IP address and device information
The consumer's signature or electronic equivalent

TCPA Rules for Special Cases

Some message types follow different consent paths under the TCPA. Political campaigns running peer-to-peer texting, for example, often rely on the FCC's human-intervention standard rather than the strict autodialer rules — see the P2P texting TCPA compliance guide for political campaigns for the full breakdown of when P2P helps, when Campaign Verify is required, and where carrier policy still controls delivery.
