ACRISS Members have addressed this problem and provided definitions to help the booking process. Please refer to ACRISS Abbreviations page under Travel Agent tab.

5. What if I or my client wants to change the return location after the rental has started?

8. Can I book a delivery and collection through the GDS or other travel technology partner?

This depends on the car rental company and travel technology site used. Sometimes the car rental company needs information which cannot be carried or held through a GDS or partner site. For further information on the format and instructions on how to book through partner sites please refer to the GDS prompt guides under Travel agency tab.

14. What should I do if I want to complain about my car rental experience?

If you or your client is not satisfied with the booking or car they received and wish to make a complaint, it is best to contact the customer service desk of the car rental company or 3rd party the reservation was booked through.

15. Are their any special requirements or additional fees for young drivers?

Most car rental companies and all our members charge an additional fee when the renter/driver of the rented vehicle is under the minimum age limit that is generally applied. The minimum age may vary by company and country and will be different to the legal driving age. All information can be found in the POLICY pages in the GDS, car rental website and throughout the reservation process. It is therefore important that the age of the driver is indicated at time of booking in order for the car rental company to return the applicable young driver surcharge fee. It is also important to note when booking through a 3rd party or broker that the young driver surcharge might not be known until the vehicle is picked up at the rental location.

Car Classification System and codes

1. What is the difference between the ACRISS Car Classification system and SIPP?

SIPP (Standard Interline Passenger Procedure) codes is the four-letter abbreviations that identify the major features of a rental car. The ACRISS car classification matrix is derived from the original SIPP codes which was successfully used for years by the GDS (Global Distribution Systems) using the same category, type, transmission and fuel/AC used in the matrix today. ACRISS expanded on the original SIPP coding in 2006 adding the Elite categories and recently expanding on the definitions/differences for Electric/Hybrid cars. The SIPP acronym is still used in North America.

2. What is the ACRISS Car Classification system?

ACRISS Members utilise an industry standard vehicle matrix to define car models ensuring a like for like comparison of vehicles. This easy-to-use matrix consists of four categories. Each position in the four character vehicle code represents a definable characteristic of the vehicle: Category, Type, Transmission and Fuel type/Air conditioning. Car codes are created by assigning one character from each column and combining them into a four-character car code giving each model a 4 character combination that defines the above characteristics of the car. All our members adhere and comply with the car codes assigned by our experts, ensuring the customer can easily compare and make an informed choice.

3. How do I decode a 4 letter ACRISS code assigned to the car I am/have booked?

To decode the assigned ACRISS code please refer to our Car Classification system matrix

4. How do I find out what code a particular vehicle model has been assigned?

You can find out the assigned car code for a given vehicle model using our online "Car Code Search" option on the website see

5. Is the Car Classification System and coding used everywhere?

ACRISS devised and developed the existing Car Classification System from the old SIPP system used by the GDSs. It has been updated over the years and in 2006 was expanded further to include new car types and the Elite version in categories. At present this system is recognised and used in Europe, Middle East and Africa only and for European and MEA fleet only however ACRISS has plans to expand further into other regions/markets in the coming years starting with Latin America. All our members comply with the coding assigned to the vehicles for these regions as part of the ACRISS Code of Conduct.
