SIPP (Standard Interline Passenger Procedure) codes are a standard in the car rental industry, allowing customers to easily compare different car models. While reservations usually show a visual example of a car make/model, it is important to note that the same model is not guaranteed on delivery. What we do guarantee is to supply a similar type of vehicle.Due to the possibility of example images being misleading due to zoom effects and photo angles, and considering the vast variety of models around the world, it is essential to standardize procedures so that customers know exactly what they are booking.Consult the list below to create a four-letter code that meets your rental needs:1st position (Car size)- M = Mini- C = Compact- E = Economy- I = Intermediate- S = Standard- F = Large- P = Premium- L = Luxurious- O = Huge- R = Recreational- X = Special2nd position (Number of doors)- B = 2/3 doors- D = 4/5 doors3rd position (Transmission/gearbox)- M = Manual- A = Automatic4th position (Fuel/a/c)- N = Fuel not specified, without A/C- R = Unspecified fuel, with A/C- D = Diesel, with A/C- H = Hybrid, with A/C- I = Hybrid, without A/C- E = Electric, with A/C- C = Electric, without A/C- L = LPG/Gas, with A/C- S = LPG/Gas, without A/C- G = Petrol, with A/C- Z = Petrol, without A/C- U = Ethanol, with A/C- X = Ethanol, without A/CThis standardized system allows customers to choose the vehicle best suited to their rental needs, taking into account size, number of doors, type of transmission and fuel, and whether it has air conditioning or not.
