If you have created a label for an international order using your Stamps.com account in ShipStation, you may notice the resulting label has an unfamiliar domestic Ship To address. This is due to the Stamps.com Global Advantage Program (or GAP, for short).
All Stamps.com accounts created after August 6, 2019, are automatically enrolled in the Stamps.com Global Advantage Program. If you select First Class Mail International, Priority Mail International, or Priority Mail Express International as your service, you will automatically receive a Global Advantage Program label, which ships the parcel to a domestic USPS sorting center first. The shipment will be relabeled at this sorting center before being sent it to its final, international destination.
Please review our Global Advantage Program article for more details.
