SHAKEN/STIR Onboarding

If you want to use the Twilio Console to enable SHAKEN/STIR, refer to the SHAKEN/STIR Console Onboarding Instructions.

If you'd prefer to use the Trust Hub REST API, choose the instructions that correspond to your business structure.

• Direct Customer, no subaccounts
• Direct Customer using subaccounts
• ISV/Reseller with single, top-level project
• ISV/Reseller using subaccounts

The Twilio onboarding process for SHAKEN/STIR involves a vetting process.

When a customer has the following, the call will be signed with A level attestation:

• Approved Business Profile
• Approved SHAKEN/STIR Trust Product that is linked to the Business Profile
• Phone number(s) assigned to both the Business Profile & SHAKEN/STIR Trust Product (only calls from those assigned Phone Numbers will be signed "A")

When a customer has at a minimum the following, their calls from Parent and Sub-Accounts will be signed with B level attestation:

• Approved Primary Business Profile

• Approved SHAKEN/STIR Trust Product linked to their Parent Account

  • Note: There is no need to assign Phone Numbers or use Secondary Business Profiles to achieve B level attestation.

• This would also be the highest level of attestation possible if a customer is using non-Twilio phone numbers,

  • This is because Twilio cannot attest to a customer's right to use a phone number if it is not a Twilio phone number. Twilio is currently investigating solutions to this.

When a customer does the following, their calls will be signed with C level attestation:

• No approved Business Profile(s) and SHAKEN/STIR Trust Product(s) (ie if customer does nothing) OR Rejected Business Profile(s) and SHAKEN/STIR Trust Product(s)
