A2P 10DLC (US SMS Compliance)

What It Is

Application-to-Person 10-Digit Long Code. US carriers require businesses sending SMS via local numbers to register their brand and use cases. Without registration, messages get error 30034 (blocked by carrier).

Registration Flow

1. Create Customer Profile (TrustHub) → brand identity
2. Register Brand → carrier vetting (1-7 business days)
3. Create Campaign → describe your use case
4. Associate Numbers → link phone numbers to campaigns
5. Start Sending → with approved throughput

Step 1: Customer Profile (TrustHub)

// Create customer profile
const profile = await client.trusthub.v1.customerProfiles.create({
  friendlyName: 'My Business Profile',
  policySid: 'RNxxxxxxxx',  // A2P messaging policy
  email: '[email protected]',
});

// Create end user (the business entity)
const endUser = await client.trusthub.v1.endUsers.create({
  friendlyName: 'My Business',
  type: 'customer_profile_business_information',
  attributes: {
    business_name: 'Acme Corp',
    business_type: 'Corporation',
    business_registration_identifier: 'EIN',
    business_registration_number: '12-3456789',
    business_industry: 'TECHNOLOGY',
    website_url: 'https://acme.example.com',
    social_media_profile_urls: '',
    business_regions_of_operation: 'USA_AND_CANADA',
  },
});

// Assign end user to profile
await client.trusthub.v1
  .customerProfiles(profile.sid)
  .customerProfilesEntityAssignments.create({
    objectSid: endUser.sid,
  });

// Submit for review
await client.trusthub.v1.customerProfiles(profile.sid).update({
  status: 'pending-review',
});
