A2P 10DLC Campaign Vetting Delays: Twilio cannot approve 10DLC Campaigns ourselves, and must rely on third parties who control our connections to carriers to sign off. These external processes are creating several week delays for our customers. We continue to escalate these issues and are working to reduce delays wherever possible. Further details will be shared in the Campaign Vetting Changes article as they become available.

Existing Sole Proprietor OTP Verification Guide

To keep your Sole Proprietor Brands (previously known as Starter Brands) registered, you must confirm your identity with Twilio via SMS with a One Time Password (OTP) verification code. This confirmation will convert your Brand to a Verified status. You must do this by July 5 2023, or SMS traffic sent from your Sole Proprietor Brand(s) will be subject to filtering.  If this OTP check is not completed by August 31, 2023 then these Brand(s) will be removed.

What is OTP Verification for Sole Proprietor Brands?

One Time Password (OTP) verification is a new step implemented to comply with the updated A2P 10DLC registration requirements. As part of this process for Sole Proprietor Brands, customers must provide two additional pieces of information to successfully register their Brands: 

  • a U.S. or Canadian mobile phone number 
  • Brand Name

Customers with existing Sole Proprietor Brands will also need to complete this verification step in order to keep their Brands in a Verified state. This Verification step must be completed by August 31, 2023.

How do I complete the OTP Verification via Twilio Console?

You can complete the OTP Verification process from the Brands page in Twilio Console, located in the Regulatory Compliance portion of the Messaging Console.

If you’re a Direct customer using Twilio Console:

Step 1

You should have a single Brand listed, and under ‘Brand status’ it will state ‘Update Required’. Click on your Update Required Brand name to continue to the Brand Details page.

Step 2

At the top of the page, you should add your mobile phone number*, Brand Name, and Business Vertical (optional). Once you’ve filled in all the details, click ‘Submit’.


*You can only verify your Sole Proprietor Brands with a U.S. or Canadian number from a mobile provider. Entering a VoIP number (including Twilio numbers) or any other number not associated with a mobile carrier will result in an error and will keep you from registering your Brand(s).


Step 3

You should receive your OTP Verification SMS to the number you’ve specified in the previous step; the message will ask you to reply ‘YES’ to confirm*. 


*You must respond to this message within 24 hours, otherwise you will need to restart the OTP verification process again.


Step 4

Once you’ve replied ‘YES’, refresh the page, and verify that your Brand status has changed from ‘Update required’ to ‘Registered’. This update can take up to five minutes. After it shows as Registered, the OTP Verification check is complete.

If you run into any difficulties completing the OTP Verification check, contact Twilio Support.

How do I complete the OTP Verification via the Twilio API?

In addition to the Console experience detailed above, ISVs have access to complete the OTP Verification flow using the Twilio API. Follow our Walkthrough Documentation for complete details on how to interact with the Twilio API to complete the OTP Verification check.

What happens if I don’t upgrade my existing Sole Proprietor Brands?

On July 5, 2023, any SMS and MMS traffic sent to U.S. destinations via Twilio Phone Numbers that are not completely registered will begin to be subject to increased filtering.  Completing this OTP Verification check is a part of being fully registered and any Existing Sole Proprietor Brands that do not complete the check will also be subject to this filtering.

If you don’t complete the verification process by August 31, 2023, your existing Sole Proprietor Brand(s), along with any Campaigns tied to those Brands, will be deleted, and your Twilio Phone Numbers that you use to send messages with these Campaigns will become fully unregistered. 

Messages from all unregistered Twilio Phone Numbers will be fully blocked after August 31.
