Fix TCR Code 2100: Missing Opt-In

What TCR Error 2100 Means

TCR error code 2100 indicates your campaign registration lacks any identifiable consent capture mechanism that carriers can verify. Campaigns must demonstrate how recipients provide express written consent before receiving marketing messages, as required under TCPA 47 U.S.C. § 227.

Why This Error Occurs

Carriers review TCR campaign submissions to verify TCPA compliance before allowing message traffic on their networks. When registration forms omit consent URL fields, provide non-functional links, or reference general website pages rather than specific opt-in forms, automated systems trigger error 2100 and block campaign deployment.

How to Fix TCR Error 2100

Remediation requires deploying verifiable consent capture infrastructure and updating TCR campaign registration with working opt-in URLs. Organizations implementing web-based consent forms achieve carrier approval within 3-5 business days, while those requiring backend development may extend to 7 days.

1. 1

   Select Consent Capture Method

   Choose between web form opt-in (most common), SMS keyword opt-in, or point-of-sale capture based on customer journey. Web forms provide strongest documentation through timestamp logging and IP address capture. SMS keywords work for text-to-join campaigns. POS systems require integrated consent tracking.

   Technical Detail: Web forms must display on publicly accessible URLs without authentication requirements. Carriers verify consent workflows during campaign review by accessing provided URLs. Forms behind login walls, paywalls, or requiring account creation fail verification.
2. 2

   Implement TCPA-Compliant Consent Language

   Deploy affirmative action consent mechanism with required TCPA disclosure elements. Consent checkboxes must default to unchecked state. Disclosure language must identify business sending messages, state message frequency, confirm standard carrier rates apply, and provide STOP/HELP keyword instructions.

   Required Elements:

   • Business name sending messages
   • Message frequency disclosure (e.g., "up to 4 msgs/month")
   • "Message and data rates may apply" statement
   • Opt-out instructions: "Reply STOP to unsubscribe"
   • Privacy policy link
3. 3

   Configure Consent Timestamp Logging

   Implement backend systems recording consent timestamp (with timezone), IP address, user agent, and exact consent language presented. TCPA statute of limitations extends 4 years, requiring organizations to retain consent records for this duration. Carriers may request consent documentation during dispute resolution or audit processes.

   Technical Detail: Database schemas should capture: subscriber phone number, consent timestamp (ISO 8601 format with timezone), IP address, consent method (web form/SMS keyword/POS), exact language presented, form version identifier. Export functionality enables TCPA compliance audits.
4. 4

   Update TCR Campaign Registration

   Provide working consent URL in campaign opt-in workflow field. URL must load within 3 seconds, display on mobile and desktop viewports, and clearly show SMS consent checkbox with TCPA disclosure language. Resubmit campaign through CSP interface or TCR portal for carrier reverification.

   Technical Detail: Carriers test provided URLs from multiple geographic locations and device types. Forms must render properly on iOS Safari, Android Chrome, and desktop browsers. Carriers reject campaigns if consent forms fail to load or display incorrectly during verification testing.

Technical Requirements

TCR error 2100 violations stem from TCPA express written consent requirements under 47 U.S.C. § 227(b)(1)(A)(iii). Federal law mandates organizations obtain prior express written consent before transmitting marketing messages to wireless numbers using automated telephone dialing systems or prerecorded voices.

TCPA Express Written Consent Definition

Express written consent requires written agreement bearing recipient signature (electronic or physical) authorizing seller to deliver marketing messages via specified method of communication. Agreement must clearly disclose marketing nature of messages and that consent is not required to purchase goods or services.

Carrier Verification Process

During campaign review, carrier automated systems access provided opt-in URLs to verify consent mechanism existence and TCPA compliance. Systems test form functionality across device types, validate disclosure language completeness, and confirm affirmative action checkbox implementation. Campaigns failing verification checks trigger error 2100 and remain blocked until compliant workflows are deployed.

Consent Documentation Requirements

Organizations must retain consent records for 4+ years covering TCPA statute of limitations. Documentation should include subscriber phone number, consent timestamp, IP address (for web forms), exact disclosure language presented, consent method, and form version identifier. Carriers and regulatory agencies may request consent proof during compliance audits or TCPA litigation discovery processes.

Prevention Strategy

Organizations avoiding TCR error 2100 implement consent infrastructure during initial campaign planning rather than reactive deployment after rejection. Pre-submission workflow validation prevents carrier blocking and accelerates campaign approval timelines.
