Regulated Number Bundle Provisioning Requirement
Provisioning new phone numbers with identity regulations through the Twilio /IncomingPhoneNumbers API now requires an approved BundleSid. End-users will be required to include the proper documentation for regulated phone numbers, which are most phone numbers outside the US and Canada. API calls to provision regulated phone numbers that do not include a compliant BundleSID that is valid for the phone number will fail with error code 21649.
