Sipp Codes Explained

rental car parked vehicles

How do Sipp codes affect renting a car you may ask? It won't affect the rate of the car or give you a cheaper rental, however it may help you determine which car you may wish to choose.

Standard Interline Passenger Procedure (SIPP) code is four letters long and is an abbreviation for the features that the car hire may have. For example if you need a compact, 2 door car that is automatic with air conditioning, the Sipp Code may be CBAC. 

Why 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 which make it 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.

First letter
(Size of the vehicle)

Second letter
(Number of doors)
