Unit – Regulatory Compliance

Approval Process

Once you submit a Regulatory Bundle, it will take up to 3 business days to verify if the information meets Regulatory Requirements.

You can check the approval state in the approval process section.

Submitting your business information enables customers to create an identity that can be used to unlock multiple communication services, such as SHAKEN/STIR and Branded Calls.

Go to the Fastcall Settings and, under Admin Settings> Regulatory Compliance > Business Profile, add your business information to register your Business Profile.

• Legal Business Name

SHAKEN/STIR

SHAKEN/STIR uses encrypted digital signatures to share information about the caller to each provider along a call’s path from caller to recipient, such as the caller’s identity and whether the caller has the right to use the phone number they provided as the caller ID.

Register all your existing phone numbers on your business profile. Needed for SHAKEN/STIR and Voice Integrity bundles.

A2P Messaging (SMS)

All SMS and MMS messages sent to U.S. phone numbers using 10DLC phone numbers must be sent via a registered application-to-person (A2P) Campaign. Messages sent using unregistered phone numbers will be subject to a gradual increase in message blocking by Twilio or carriers.

In order to prevent this, you need to create an SMS campaign to assign your phone numbers.

Go to A2P Campaigns settings and add a campaign using the “+” icon on the table.

To create a new A2P Campaign, you have to add:

• SMS campaign use case
• Description
• 2 SMS examples
• Explain how end users consent to receive messages

Then you have to assign the A2P campaign to the phone number. Go to the phone number details, and select it in the SMS SETTINGS section.

CNAM

CNAM stands for Caller ID Name. CNAM is a feature in the United States public telephone network that identifies an incoming caller by a personal or business name associated with the phone number.

Voice Integrity

Voice Integrity helps businesses establish trust in their outbound calls through proper caller identification and compliance with industry call authentication and anti-spam standards, including STIR/SHAKEN.

This process supports caller authentication and helps reduce the risk of legitimate business calls being labeled as spam.

To set up Voice Integrity, you have to provide:

• Use case
• Business Employee Count
• Average daily call volume

Phone Regulatory Bundles

Due to country-specific regulations, you’ll need to create a Regulatory Bundle for each type of phone number, so you can provision and use phone numbers legally.

For example, if you need to provision and use German Toll-Free phone numbers, you’ll need to create and submit a Regulatory Bundle for this type of phone number.

For each Regulatory Bundle, you will have to upload Supporting Documents.

To create a new Regulatory Bundle, you have to add:

• Phone number’s Country
• Type
• Name: Use a unique nickname you will easily recognize.
• Email to get notifications.

Once you submit a Regulatory Bundle, it will take up to 3 business days for Twilio to verify if the information meets Regulatory Requirements.
