If you are sending outbound texts from local US numbers to local US numbers, follow the steps below to comply with 10DLC regulations.
1. Create a Brand
For every perceived sender, you need to create a brand:
👉 How to Create a 10DLC Brand
The brand information must match the IRS Form CP-575 to achieve "Verified" status.
This is because The Campaign Registry (TCR) uses the IRS database as their source of truth.
2. Create a Campaign
Once your brand is Verified, create a campaign:
👉 How to Create a 10DLC Campaign
Important:
You must select "True" for Opt in, Opt out, and HELP radio buttons.
If not, TCR will reject the campaign creation.
Common errors to avoid:
Campaigns with a TCR ID starting with
4b3or a status of "Failed TCR Review" were not created successfully.This often happens if the campaign is created before the brand is verified.
3. Telnyx Review of the Campaign
