For international customers except Canada:
If you choose first class mail, you will only get a customs id number for your shipping confirmation.
Customs id number is not a tracking number. This number will only trace the package to Jamaica New York, which is the point when it leaves the USA. First class packages are not trackable after they leave the USA.
Only priority and express packages would be traced all the way to your door.
Please chose Priority mail just in case you would like to know the progress of your package.
