Add On for Federal Tax Id Validation for Wholesale Customers

[lifestar]

I have searched through the contributions for hours- perhaps I am not using the correct search terms. Is there a contribution that will immediately validate a US Federal Tax ID at registration so that wholesale customers can immediately view pricing and order upon completing the registration form? I see contributions that will allow me to manually validate - but would like to make it easier for the customer to purchase instead of waiting. Thanks in advance....
