New brand registration statuses and behavior in A2P 10DLC ISV APIs GA

ISV customers using the APIs to register brands for US A2P 10DLC will see two new values for brand registration status (‘status’ field):

  1. IN_REVIEW 
  2. DELETED

Customers will also see new behavior for this field. You can check the github changelog here for the new enums available November 1. Starting December 1, using GET API to check brand registration Status will return ‘status’ as IN_REVIEW when your brand is under manual third-party review. The manual review can take 7+ days. Status ‘DELETED’ will be returned when a brand is deleted. Since a new status type can be a breaking change for you, please update your code before Dec 1.

Additionally, behavior of the ‘status’ field now represents a more accurate status of the brand as it is APPROVED only when your brand registration is complete and you can move to campaign creation. This eliminates the need for you to check multiple fields to know the action required from you on a brand. You can see the new behavior of status in the A2P wizard within Twilio Console, and in the API. Before December 6th, IN_REVIEW status will be visible on Console but not be returned in API to give adequate time for your API integration to be updated.


New U.S. A2P 10DLC registration flows are now available for 527 Political Organizations and K-12 Education customers. These new registration flows are available in both the A2P wizard in the Console as well as ISV APIs.

For more information on eligibility, messaging limits, pricing, and FAQs for these registration flows, please see our article on Special Use Cases for A2P 10DLC.

Conversational U.S. A2P 10DLC campaign type renamed to Proxy GA

Customers registering for U.S. A2P 10DLC should use the new name “Proxy” instead of the old name “Conversational” when registering for campaigns of this type. This change is applicable in the A2P wizard in the console as well as ISV APIs (Create Campaign Use Case step). ISV API customers need to update their API integration.

This name change is to better represent the campaign type, which is meant for proxy/pooled numbers supporting personalized services and non-exposure of personal numbers. Some customers had incorrectly registered campaigns as Proxy/Conversational which should’ve been registered as Customer Care.

You can read more about the Proxy campaign use case here.

Customers can view reasons for brand registration failure in A2P 10DLC GA

Customers can now view the reasons for their brand registration failures in the A2P wizard in the console or via the ISV APIs for US A2P 10DLC. In the A2P Wizard in the Twilio console, brand failures will result in an error screen with reasons for the failure and instructions to fix your brand registration before you can move forward. The GET Brand API call returns the failure reasons for ISVs registering their customers via API. You can review the failure reasons and API details here and reduce the likelihood of your brand registration failing by following the brand registration best practices here.

High quality message templates on the account that it was previously registered on will also be copied over to the new account on Twilio.

Mock Brand and Campaign Registration for US A2P 10DLC Beta

ISV Customers with a registered US A2P ISV Brand can now test their API integrations with Twilio by registering Mock Brands and Campaigns. The Mock Brand and Campaign API allows you to develop and test applications against Twilio’s A2P Brand and Campaign APIs without incurring any A2P 10DLC related fees.

Mock brands and mock campaigns are created similarly to brands and campaigns registered against the non-mock A2P APIs. Any campaign registered alongside a Mock Brand will automatically be considered a Mock Campaign and will not allow Messages to be routed on US A2P routes. And Mock Brands and campaigns expire after 30 days. These are some important restrictions and considerations to keep in mind when you’re using this API, with detailed explanations available in this guide.


ISV customers can now view additional brand registration information for any Secondary Brand they are registering for US A2P 10DLC. On the successful registration of an A2P brand, customers can view this additional information when using the GET Brand Registration API.

“russell_3000” is returned ‘true’ by TCR when the brand is verified as a Russell 3000 brand.

“tax_exempt_status” returns the verified tax-exempt status of a US-based nonprofit brand, such as ‘501c3’, as verified by TCR. Otherwise, this is returned as ‘N/A’.

“skip_automatic_sec_vet” is returned 'true' for ISV customers who choose to skip automated secondary vetting for a secondary brand.

You can find more details for these in ISV Onboarding API docs.

ISV customers can skip secondary vetting for any US A2P 10DLC Brand GA

ISV customers can now choose to skip automated secondary vetting for any Secondary Brand they are registering for US A2P 10DLC. Twilio continues to recommend secondary vetting because it raises both campaign throughput and daily volume limits beyond minimums allowed by carriers. With automated secondary vetting, customers can maximize throughput and daily limits without extra registration steps. 

That being said, we understand that some of our ISV customers may not want to complete secondary vetting for some of their customers based on the additional vetting fees and the usage patterns of those customers. Customers can review the usage limits available to a brand without secondary vetting in throughput for US A2P 10DLC.

This parameter SkipAutomaticSecVet is an optional parameter during brand registration, which can be used to skip secondary vetting for an A2P brand. You can find more details in ISV Onboarding API docs.


A2P 10DLC brand and campaign registration for all 501(c) nonprofit organizations is now available as part of Twilio’s A2P 10DLC Console and ISV API onboarding experience.Nonprofit organizations can register using the Charity / 501(c)(3), Political, or Standard use cases depending on their entity type:

  • 501(c)(3) organizations should register campaigns with the Charity / 501(c)(3) special use case. Charity / 501(c)(3) is a reserved use case for 501(c)(3)s to receive discounts on A2P carrier fees.
  • 501(c)(4), 501(c)(5), and 501(c)(6) organizations sending messages that are political in nature should register with the Political special use case, or register non-political messaging with standard campaign use cases. The Political use case receives increased messaging throughput on A2P.
  • All other 501(c) designations should register their campaigns with standard campaign use cases.

For more details on the Charity / 501(c)(3) and Political campaign use cases, please see this support article on special use cases.
Note: We're still working to enable registration for 527 Political organizations and for the Emergency Special use case.


Messaging Customers are required by U.S. carriers to register for A2P 10DLC. Independent Software Vendors that offer other customers the ability send SMS and MMS need to register themselves as an ISV brand via Trust Hub in the Twilio console and then they can register each customer as a Standard Brand or a Starter Brand. Registered Brands can then register use case campaigns.

Starter Brand registration is now available for all independent software vendor (ISV) customers to register your customers for US 10DLC compliance and send SMS and MMS in the US with 10-digit long codes. Starter Brand registration is intended for customers who send fewer than 3,000 daily SMS segments and MMS messages over 10-digit long codes AND use five or fewer 10-digit U.S. long codes. Twilio is covering the costs for Starter Brand registration and monthly campaign fees.

ISV Customers can read the Starter Brand overview and step-by-step API walkthrough as they prepare to register their customers.

A2P Registration now automatically includes Secondary Vetting GA

Twilio continues to streamline registration with US Carriers for Long Code Messaging (A2P 10DLC). All A2P brand registrations are now subject to an additional $40 one-time vetting fee. Twilio will automate the vetting process and cover the vetting fee for primary Brands until October 1, 2021 and Secondary Brands created for ISVs until August 21, 2021. 

With automated secondary vetting, you will benefit from:

  1. Increased daily messaging limits to T-Mobile. See the article ‘T-Mobile daily message limits for long code messaging with A2P 10DLC’ for details.
  2. Increased throughput on your campaigns since secondary vetting will ensure accuracy of information and maximizing the TCR Score. See more details in our support article ‘Message throughput (MPS) and Trust Scores for A2P 10DLC in the U.S.

There is no special action needed from customers to benefit from secondary vetting after this change, it will automatically be triggered for all brands registering for US A2P compliance.
