Understanding TCR and DCA Verification
TCR (The Campaign Registry) is the central authority where all brands and campaign use cases are registered for A2P 10DLC messaging in the United States.
DCA (Direct Connect Aggregator) is the carrier-integrated layer responsible for reviewing, approving, or rejecting campaigns based on message content, compliance, and use case evidence.
Even if TCR accepts a campaign, a DCA (like AT&T, T-Mobile, or their intermediaries) may still reject it during their manual or automated verification process.
If a campaign is rejected by a DCA, you may edit and resubmit the campaign. Note: Each resubmission incurs a $15 fee. Multiple rejections may cause longer review delays or message filtering.
