Subaccounts are a type of account within Twilio that allow you to create mini-accounts "owned" by your project. A subaccount is an ideal way to separate your project’s phone numbers, usage, and application settings for a specific end customer.
Our users who commonly make use of subaccounts are:
- Resellers of our product who have different customers of their own and want to keep customer 1's data separate from customer 2's data
All of your project users have access to your subaccounts, and any usage the subaccount runs into rolls up to your main Twilio project.
Still, you can pull usage logs on the subaccount level so you could, for example use your usage data to bill a client or an internal department for the usage on that account.
By default a project can only have 1000 subaccounts. Closed subaccounts do not count towards this limit. If your project is approaching 1000 subaccounts, contact Twilio Support to ask about raising this limit.
For more information on subaccounts, see our subaccount documentation.
