Our company is located in the United States so there is no VAT associated with your order. Additionally, you were not charged tax. Since we are US company we do not have a VAT number, nor have we charged any VAT. For this reason, there is no VAT number on our invoices and we cannot legally add a VAT number to your invoice. The order confirmation we have provided is all that we can provide for your 
records.

Please let us know if you have questions and thank you for your understanding.
