ePER and its four brands
ePER holds Fiat, Alfa Romeo, Lancia and Abarth on one data set. Platform sharing between them is heavy — an Abarth 500 is a Fiat 500 underneath, and Lancia's later range drew directly on Fiat architecture — so a single number often covers components fitted across several badges.
For a workshop that is a practical advantage: one catalog, one login, and a part identified for a Punto is identified for its relatives at the same time.
Eight digits, no grouping
Fiat numbers are eight digits with no letters and no readable group structure — 77365432, 55234123. Like Volvo's, they tell you very little on their own, which puts the burden on navigating to the right assembly group and reading the number from the parts list rather than reasoning about it.
Older Fiat numbers appear in other lengths as the group's systems have consolidated; the catalog carries the supersession chains forward from them, which is exactly what a frozen offline copy stops doing.
Where Fiat builds split
Engine family is the main driver, particularly across the long-lived diesel and small petrol ranges, whose service parts differ substantially between variants that share a nominal displacement. Market specification adds lighting and emissions differences.
Ducato is the commercial exception worth flagging: it is used as a base by a large part of the motorhome industry, and those conversions leave the base vehicle's parts list intact while adding equipment the catalog does not cover — so identify the base vehicle by VIN and treat the conversion separately.
Common Fiat nameplates
These nameplates help you find the right vehicle family. Confirm the exact model, market and production period against the active catalog before quoting a part:

Frequently asked questions
What is ePER?
The electronic parts catalog covering Fiat, Alfa Romeo, Lancia and Abarth on one data set.
Does it cover Alfa Romeo and Lancia?
Yes, all on the same catalog — and on shared platforms the three brands share part numbers.
How is a Fiat part number structured?
Eight digits with no letters or grouping. It carries no readable assembly-group block, so the exploded diagram rather than the number identifies the component.
