The present invention provides systems and methods for global address verification of a transaction, such as a transaction card purchase. In accordance with an exemplary embodiment of the present invention, the system verifies a billing address and/or an alternate address (e.g., shipping address) in a single transaction. The billing address and/or the alternate address are associated with a transaction card purchaser. If the billing and/or alternate addresses are verified, then the transaction card issuer may offer a payment guarantee to the merchant. The merchant may choose to ship the purchased item to either a billing address or an alternate address. If the address is not verified, then the transaction card issuer may choose not to offer a payment guarantee to the merchant, and the merchant may choose not to ship the item to the alternate address.
