Sipp Codes Explained
You may wonder how those odd four-letter codes you sometimes see describing rental cars affects you. The answer is that it does not affect the rate of the car or give you a cheaper rental. It does, however, help you identify the car and some of its key features.
Standard Interline Passenger Procedure (SIPP) code is four letters long and is an abbreviation for the major features of a car rental. For example, if you need a compact, two door car that is automatic with air conditioning, the Sipp Code may be CBAC.
Why do car rental companies use SIPP codes?
Thousands of different vehicles are being distributed in the world and for that reason alone, there needs to be a system of arranging and classifying them. Thanks to SIPP codes it is a piece of cake to compare rental cars by organising similar vehicles together.
The code, which consists of four letters, details different things, including the type of vehicle, the number of doors, the transmission or whether it has air conditioning or not, as shown in the table below.
