Transfer phone numbers from primary account to subaccount
To transfer phone numbers between subaccounts and your main account, use your main account's credentials when making an API request.
Make an HTTP POST request to an IncomingPhoneNumber instance URI, set the parameter 'SubAccountSid' to the desired account's SubAccountSid, and remove the phone number from its main account.
- Number configurations may need to be reconfigured.
- Any Toll-Free number verifications, A2P registrations or Trust Hub enrollments will need to be resubmitted and reconfigured.
If any of the phone numbers you would like to transfer have Address Requirements, you will need to create a compliant Address in the new subaccount before transferring the phone number.
Remember, closing a subaccount as described above will release all of that account's phone numbers, so you might consider transferring all numbers to your main account beforehand if you want to keep them.
Important Note
