Twilio registration for A2P 10DLC is now available for all customers. Please be aware as you register that there are still limitations as Twilio rolls out A2P 10DLC. These limitations are being removed over time, and this article is being updated accordingly as the situation changes.
There are also some limitations that uniquely affect ISV-type customers. Those are listed separately below. Read on for details.
- Subaccount limitations
- Limitations with sharing A2P Brand registration across multiple Twilio Account SIDs
- Limitations specific to ISV-type customers
- Limitations for International (Non-US / Canada) entities
- Other considerations
It is not currently possible to create a Primary Business Profile on a subaccount. However, if you are a Direct customer and you complete registration of your Primary Business Profile and A2P Brand on your Twilio parent account, you can share it to your subaccounts. You can reach out to Support if you don't want this parent-to-subaccount profile sharing to take place. See Limitations with sharing A2P Brand registration across multiple Twilio Account SIDs below.
Limitations with sharing A2P Brand registration across multiple Twilio Account SIDs
Sharing from a primary Twilio Account SID to another primary account's subaccounts
If your business has multiple use cases spread out across multiple primary Twilio Account SIDs ("projects"), you can now request Twilio share your A2P Brand registration to another primary Twilio account. However, if the second primary Twilio account has subaccounts, you will not be able to share the (already-shared) Brand from that parent Account SID to those subaccounts.
This is an uncommon scenario, but if this applies to you, Twilio is working toward a solution, however there is no ETA. As of now, you can solve this by registering your A2P Brand again on any additional Primary Accounts that have subaccounts, and then share the Brand to those subaccounts.
Limitations specific to ISV-type customers
No phone number registration status for externally-registered Campaigns.
Twilio does not currently have the ability to retrieve number registration status for externally-registered Campaigns. If you are an ISV who registers Campaigns directly with TCR and associate those with Twilio numbers, we cannot currently confirm which of your Twilio numbers have been fully migrated to your A2P registration.
Limitations for International (Non-US / Canada) entities
It is possible to register a Standard Brand for A2P 10DLC as long as the entity that is being registered has a Tax ID issued by their government. For entities that do not have a Tax ID, if they are based in the United States or Canada they can register as a Sole Proprietor Brand; however, entities outside of the United States and Canada cannot register as a Sole Proprietor Brand.
Unfortunately, at this time there is not an A2P 10DLC registration path available to entities of this type. We recommend considering using a Verified Toll-Free Number in order to send traffic to the United States.
Short code numbers or Toll-Free numbers in your Messaging Service will not be affected by A2P 10DLC registration.
