I sold a leather jacket to someone in Ireland.
I was able to track the package to Philadelphia which i assume is customs. It appears that it left there but nothing after. No tracking. Nothing to tell me an ETA.
Suggestions
If you can download an app, I use “packages”, it tracks all carriers . Another, is 17 track, which you can also access online. Put in the number and it will give more info. I use it to track local and international packages, inbound to me and outbound.
Did you use Etsy Labels / Global Shipping with Ascendia?
If so, The Philadelphia address is probably the Ascendia collection hub. The parcel is then relabelled with a different, International Tracking Number and forwarded in bulk with all other parcels going to the Ireland. Was it Northern Ireland or Republic of Ireland because processes are different? NI uses Royal Mail and ROI uses An Post
This is how to find the new Label / Customs information and Carrier
Etsy provides customs IDs for Global Postal Shipping Label shipments. These ID numbers can be used to track the package. Customs IDs are created when the package is prepared to leave the United States.
Buyers can enter a customs ID on the website of the shipping carrier, or on sites like AfterShip, to track their package.
