• Outbound Global Express usually starts with letter E and another letter (so there will be two letters), 9 numbers, and closed by US. Again, on the upper right corner area under the bar code. EF 000 111 222 US will be the example.
• Inbound Global Express usually starts with letter E and another letter (so there will be two letters), 9 numbers, and closed by two letters from the origin country. For instance, EF 000 111 222 HK will be located on the right upper corner area.
