USPS has no precise tracking outside of the U.S. It just shows the last point where the package was before it boarded a plane and flew out to foreign customs. It only tracks within the United States and sometimes when it's in the destination country. You may not see any updates at all until the package is delivered, or not even then. That's normal and most common with USPS 1st Class International "tracking".
Exactly. After it processes through the International Service Center (ISC), you have to check the customs number through your own country's postal service for any kind of updates after that. And sometimes, they never update anything until after the package is delivered.
Thank you
I double checked with my local country postal office and they said the package was not arrived yet.
In Vietnam, due to the amount of goods travel between Vietnam and US are really big, they use the same tracking number given by USPS (EMS, Priority Mail or First Class)
I need to wait for a while even they package delivery is Priority Mail.
I hope that my package doesn't get lost in the middle of nowhere
