UKRC Compliance
If you're creating a UK compliant phone number, fill out this form in addition to the process outlined below.
Paradox provides a native, self-service 10DLC (10-Digit Long Code) registration system that allows teams to submit, manage, and monitor SMS compliance directly within the CEM.
Use cases
- New Implementation: Your team needs to register a new brand to begin SMS outreach in the US/Canada.
- Account Scaling: Your team creates a new CEM account and needs to associate it with an existing, approved 10DLC brand.
- International Expansion: Your team operating outside the US/Canada needs to unlock the Channels page without a 10DLC requirement.
- Internal Oversight: A CS or Support team member needs to check the live status of your registration.
Configuration
This feature will be configured for you during implementation by your Paradox Team or System Implementor. This process is outlined here.
