It is now required that buyers registered on the Italy site provide their Codice Fiscale ID (similar to the Social Security Number for US citizens) before buying an item on the Italy site.
On the Spain site, a Spanish seller has the option to require that Spanish buyers (registered on Spain site) provide a tax ID before checkout. This option is set by the seller at the account level. Once a Spanish buyer provides a tax ID, this tax ID is associated with his/her account, and once a tax ID is associated with the account, Spanish buyer will be asked to provide the tax ID during checkout on all eBay sites. Buyers with a registered address outside of Spain will not be asked to provide a tax ID during checkout.
This container is only returned for Spanish or Italian sellers when the buyer was asked to provide tax identifier information during checkout. A BuyerTaxIdentifier will be returned for each tax ID that is associated with the buyer's account.
Note: For an Authenticity Guarantee program order returned in GetItemTransactions or GetSellerTransactions, this is the address of the authenticator's warehouse. The authenticator is responsible for delivery to the buyer's shipping address.
