Subaccounts in Twiilio are accounts owned by your main account. A subaccount allows you to separate each of your customer's use of Twilio and keep it separate from all other customers. This allows you to manage the activity and resources of each customer independently.
Subaccounts are also a great way to separate your Twilio usage and act on behalf of your customers, agents, or employees.
If you are running a hosted service that relies on Twilio, you can create a Twilio subaccount for each customer that signs up. Then, if a customer closes their account with your service, you can deactivate the associated Twilio subaccount.
Subaccounts allow you to use the Twilio REST API just as you would for a single account; a subaccount can have its phone numbers and caller IDs, applications, and SIP domains. You can manage a subaccount's calls, messages, recordings, and transcriptions without affecting other subaccounts.
Important Notes
- A main account can only have up to 1000 sub accounts by default. If you need more subaccount, please contact support.
- By default, closed subaccounts will be automatically deleted 30 days after closure.
