The customer code determines the customer who ordered the aircraft 'NEW' from Boeing. If the aircraft ever changes hands, the customer code remains the same. Through use of the Boeing Customer Code you can always be sure who the original customer was.
In the example below, the customer code '38' is highlighted red. This is where the customer code appears in the model number. In this example, the customer is Qantas.
Boeing 747-438ER
Some of these codes may no longer be used because an airline has become defunct or merged with another airline for example. These codes are correct as of May 2012.
