A sub-account enables hierarchical management of your resources. You can use sub-accounts to distribute numbers and applications among various sub-organizations.
Sub-accounts use the credits from the main account and hence do not need to be recharged separately.
Sub-accounts can be created either by using the Plivo dashboard which can be done by clicking on the following link:https://console.plivo.com/subaccounts/
You could also create a sub-account by firing an API request which you can refer to the details we have mentioned in the following link:https://www.plivo.com/docs/api/account/#create-a-subaccount and create a sub account .
Note: You can rent or search for numbers only under the main account. You can associate numbers with a sub-account once it has been rented.
