Guide
ACRISS codes for compact car hire
How rental class codes can help explain compact, economy, body style and transmission without promising a model. This guide is framed for Northern Ireland enquiries.
Four letters, four decisions
ACRISS-style codes separate class, body type, transmission or drive, and fuel or air-conditioning information. For NI, connect this point to the route, access and driver details before calling.
That is useful for compact-car hire because a category name alone does not explain doors, gearbox, luggage fit or the particular model supplied. For NI, connect this point to the route, access and driver details before calling.
Compact is a category
A compact booking discussion should stay category-led unless a confirmed fleet product says otherwise. For NI, connect this point to the route, access and driver details before calling.
Use the call to confirm whether the group suits passengers, luggage, motorway distance and any automatic request. For NI, connect this point to the route, access and driver details before calling.
Why this matters locally
City-centre car parks, airport bags and hotel access can make a nominally small category unsuitable. For NI, connect this point to the route, access and driver details before calling.
The safest customer-facing wording is to ask for the confirmed group and its practical fit before planning the journey around it. For NI, connect this point to the route, access and driver details before calling.
Call checklist
Ask about vehicle group, transmission, luggage, driver checks, excess or deposit terms, collection details and whether the allocated registration needs a charge-zone check. For NI, connect this point to the route, access and driver details before calling.
Do not arrange onward travel around an assumed model name. For NI, connect this point to the route, access and driver details before calling.
