Toll-Free Registration

As of July 2023, all messages sent with unregistered 10DLC phone numbers are subject to gradual message blocking by Twilio.

There will be a full block of all unregistered US-bound messages sent after August 31, 2023. Your messages will bounce back error code (30034) and you will still be charged Twilio messaging rates.  Through August 31, 2023, unregistered messages successfully terminating onto carrier networks are subject to additional carrier fees for unregistered messages. 

Twilio is unable to extend the timeframe for customers who are unable to complete all three steps of the registration process by the deadline. This includes:

• Brand verification
• Campaign approval

• Phone numbers submitted for the Messaging Service associated with each campaign

  US Carrier penalties for non-compliant messaging

As an alternative to A2P 10DLC, you can use other number types like short codes, WhatsApp Messaging, Twilio Verify API, and toll-free phone numbers. 

A lot of customers are seeing success with toll-free numbers because they can be used for any use case. They provide high-throughput SMS once verified and are voice enabled. And the verification process is handled by Twilio and usually takes less time than 10DLC approval. You can complete the toll-free verification via Console or API.

Yes. There is a Sole Proprietor use case for hobbyist/student developers and businesses without an EIN (Employer Identification Number or Federal Tax Identification number). It lets you register and send A2P 10DLC messaging on a limited basis: 

• One campaign
• One associated phone number
• 1,000 msg/day. 15 msg/minute limit per campaign (T-Mobile)

You can read about the differences between direct brands, ISVs, and sole proprietors here. If you’re still not sure whether you should register as a direct customer or ISV, here are two key questions to consider:

1. Who do your end users (message recipients) think they are receiving messages from? Are they interacting with your brand/company, or your client’s brand?
   • If your end users are aware of your brand and think of their interaction as happening between them and your company, you are probably a direct customer.
   • If your end users are not aware of your business, and they think they are interacting with your client directly, you are an ISV.
2. How much control do your clients/users have over the contents of the messages that are sent via your platform?
   • If you do messaging on behalf of others, but it’s template-based messaging with little to no customization or control by your clients, you may still classify yourself as a direct customer.
   • If you give your clients the ability to send messages on their behalf (which end users would assume are originating from your client directly) then you are an ISV.
