Q. Can a corporate also use Utransfer service?

Yes, a corporate can use Utransfer as long as the corporate is a beneficiary.
Utransfer doesn't provide a service for a corporate as a sender so far.

[Available service]
Domestic Individual → International Individual/Corporate

[Unavailable service]
Domestic Corporate → International Individual/Corporate
International Individual/Corporate → Domestic Corporate

※ The sender's name is not appealed in the beneficiary's transaction history but the financial institution's name and, sometimes, it makes the transaction delayed due to check the sender's identity in the recipient bank occasionally.

If you can provide the Transaction Receipt of Utransfer which shows sender's name and amount to the beneficiary (individual or corporate) as soon as the transaction has initiated, the transaction can be confirmed quickly.
