The Electronic Delivery Confirmation program, also known as E-DELCON, allows participating countries to update USPS® tracking for packages that are shipped internationally. In most cases, this results in door-to-door tracking... although some countries may not update the tracking as reliably, even though the packages are still en route for delivery.
