Subaccounts are a divisions within a Twilio project that are "owned" by the project. Subaccounts share the same balance with a project, but have their own usage and resources. All of your project users have access to your subaccounts.
A subaccount is an ideal way to separate your phone numbers, usage, and application settings for a specific end customer. Our users who commonly make use of subaccounts are mostly 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
By default an upgraded project can only have 1000 subaccounts, a trial project can have only a single subaccount. Closed subaccounts do not count towards this limit.
If your upgraded project is approaching 1000 subaccounts, contact Twilio Support to ask about raising this limit.
For more information on subaccounts, please see Getting Started with Twilio Projects and Subaccounts.
