# Tax identification numbers

The Digital River Extension allows shoppers to enter their **Tax Identification Number** during order placement, have the ID validated, and, if appropriate, the order totals will be updated accordingly.

The shopper must:

1. Select the **This is a Business Purchase** check box on the **Shipping Address** screen, when purchasing physical goods, or on the **Payment Information** screen when purchasing digital or virtual goods.\
