Telnyx

A brand is your registered business identity in the 10DLC ecosystem. Before you can create messaging campaigns or send A2P messages on US long codes, you must register your brand with The Campaign Registry (TCR) through the Telnyx API. Your brand’s vetting score directly determines your messaging throughput limits.

Prerequisites

A Telnyx account with API access
Your API key
Business information: legal name, EIN/Tax ID, address, phone, email, website

For Sole Proprietor registration (individuals without an EIN), see the Sole Proprietor guide. This guide covers standard business brand registration.

Brand entity types

TCR supports several entity types. Choose the one that matches your business structure:

Entity Type	API Value	Description	Vetting Required
Private for-profit	`PRIVATE_PROFIT`	Private companies (LLC, Inc, etc.)	Yes
Public for-profit	`PUBLIC_PROFIT`	Publicly traded companies	Yes
Non-profit	`NON_PROFIT`	501(c)(3) or equivalent	Yes
Government	`GOVERNMENT`	Federal, state, or local government	Yes
Sole Proprietor	`SOLE_PROPRIETOR`	Individuals without EIN	OTP only

Sole Proprietor brands have significant limitations: 1 campaign, 1 phone number, low throughput. Use standard registration if your business has an EIN.

  "data": {
    "brandId": "BXXXXXX",
    "entityType": "PRIVATE_PROFIT",
    "displayName": "Acme Corp",
    "companyName": "Acme Corporation",
    "ein": "12-3456789",
    "identityStatus": "VERIFIED",

    "state": "NY",
    "city": "New York",
    "street": "123 Main St",
    "postalCode": "10001"
  }
}

Step 2: Retrieve brand details

After creation, check your brand status and details:

curl -X GET https://api.telnyx.com/v2/10dlc/brand/BXXXXXX \
  -H "Authorization: Bearer YOUR_API_KEY"

Brand statuses

Status	Meaning
`SELF_DECLARED`	Brand created, not yet verified
`VERIFIED`	Identity verified by TCR
`VETTED_VERIFIED`	Third-party vetting completed
`UNVERIFIED`	Verification failed — see troubleshooting

Step 3: Submit for external vetting

Vetting is performed by a third-party partner (e.g., Campaign Verify) and produces a trust score from 0 to 100 that directly impacts your messaging throughput.

curl -X POST https://api.telnyx.com/v2/10dlc/brand/BXXXXXX/externalVetting \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "evpId": "AEGIS",
    "vettingClass": "STANDARD"
  }'

Vetting classes

Class	Cost	Use Case
`STANDARD`	~$4	Default for most brands
`ENHANCED`	~$40	Higher trust scores, faster approval

Vetting score impact on throughput

Your vetting score directly controls your carrier-specific throughput. See the 10DLC Rate Limits guide for detailed carrier tables.

Score Range	T-Mobile Throughput	AT&T Throughput	Category
0–24	2,000/day	1 MPS	Low
25–49	10,000/day	4 MPS	Medium-Low
50–74	50,000/day	10 MPS	Medium
75–89	100,000/day	25 MPS	High
90–100	200,000+/day	75 MPS	Highest

Without vetting, brands default to the lowest throughput tier. Always submit for vetting before creating campaigns.

Step 4: Check vetting results

Vetting typically takes 1–7 business days. You can poll or use webhooks to check the result.

# List external vettings for a brand
curl -X GET https://api.telnyx.com/v2/10dlc/brand/BXXXXXX/externalVetting \
  -H "Authorization: Bearer YOUR_API_KEY"

Step 5: Update a brand

If your brand details change (address, phone, etc.), update them via the API:

curl -X PUT https://api.telnyx.com/v2/10dlc/brand/BXXXXXX \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "phone": "+15559876543",
    "email": "newemail@acmecorp.com",
    "website": "https://www.acmecorp.com"
  }'

Updating certain fields (company name, EIN) may trigger re-verification. Contact support if you need to change core identity fields.

List all brands

Retrieve all registered brands on your account:

curl -X GET "https://api.telnyx.com/v2/10dlc/brand?page[size]=25" \
  -H "Authorization: Bearer YOUR_API_KEY"

Common rejection reasons and fixes

EIN mismatch — company name doesn't match IRS records

Cause: The companyName field doesn’t match what the IRS has on file for that EIN.Fix: Use your exact legal name as registered with the IRS. Check your EIN confirmation letter (CP 575) or search the IRS tax-exempt organization database for non-profits.

Invalid EIN format

Cause: EIN must be in XX-XXXXXXX format (9 digits with a hyphen after the first 2).Fix: Double-check your EIN. It should look like 12-3456789. Don’t include spaces or extra characters.

Website not accessible or doesn't match business

Cause: The vetting partner couldn’t access your website, or the website content doesn’t match the registered business.Fix: Ensure your website is live, publicly accessible (no authentication required), and has content that clearly identifies your business. The domain should ideally match your business email domain.

Phone number not valid or not reachable

Cause: The business phone number provided is not a valid, reachable US/CA number.Fix: Provide a working business phone number in E.164 format (e.g., +15551234567). The number should be answerable during business hours.

Address verification failed

Cause: The provided address doesn’t match USPS records or can’t be verified.Fix: Use your exact business address as registered. Verify it through USPS address lookup.

Duplicate brand — EIN already registered

Cause: A brand with this EIN is already registered (possibly by another CSP or a previous registration).Fix: You can only have one brand per EIN. If you previously registered through another provider, you may need to import or transfer the brand. Contact Telnyx support for assistance.

Appeal process

If your brand is rejected or receives a low vetting score, you can appeal:

Review the rejection reason

Check the brand’s identityStatus and any associated error messages via the API or Mission Control Portal.

Fix the identified issues

Update your brand information to address the specific rejection reason using the update brand API.

Re-submit for vetting

After updating your brand, submit a new external vetting request. Each vetting submission incurs a fee.

Contact support if needed

For complex cases (EIN transfers, duplicate brands, identity disputes), contact Telnyx support with your brandId and details.

Re-vetting after fixing issues often results in a higher score. The most common improvement is ensuring your website, company name, and EIN all align.
