The following table outlines the fields that are part of a typical transaction as represented by the transaction object:

`billing_address`		See Address Object Fields.

You can use this field to provide the country code, if that is part of the number. For example, IE1234567X. You can also use the `billing_country_code` field for specifying the country. If a value is entered in the both fields, the country code value in the `buyer_tax_number` is used once it is verified.
