Ford part numbers

“FINIS” is the abbreviation for “Ford International Numeric Identification System”.


These 7-digits numbers serve as unique “ordering numbers” for car parts. These numbers allow ordering parts from dealers and also to conduct searches in internet.

:!: HINT: When a component is replaced with a newer version, the new version is assigned a new FINIS number. This new version might also be used as a spare part in order vehicles. In this case, the older Ford FINIS will no longer be available. Nevertheless, this does not prevent other dealers from offering these old parts.

“SPN” is the abbreviation for “Spare Part Number”. This part number is composed of “Prefix - Base number - Suffix”:

Prefix - Base number - Suffix

These numbers can be found in stickers or stamped in plastic parts.


The prefix always indicates on which vehicle the part is to be used.

The 1st digit indicates the year in which the part was first introduced in the vehicle series (e.g. Mondeo MK4):

Prefix Introduction year
6xxx 2006
7xxx 2007
8xxx 2008
9xxx 2009
Axxx 2010
Bxxx 2011

There are cross-platform parts/assemblies, like radios or FSE modules. Also an excellent example of this is the IB5 transmission from the Fiesta, found in (very few) Mondeos.

Base number

The base number describes the actual part. This base number will always be the same for all vehicle series. This means that the A pillar in a Focus will have the same base number as in a Mondeo. Of course, the part itself will differ.


The suffix is normally composed of two characters (e.g. “-AB” or “-BE”)

The first character is normally the feature version or variant. For some components, the range of features increases as the alphabetical order of the character increases. However, this is not always the case. As a rule of thumb, a given letter quantifies a certain range of features for the part. A special case is the feature letter “X”. It usually corresponds to a so called, substitution part. These correspond to the highest feature version that was available, and therefore serve as a generic replacement for all lower functional versions.

The second character indicates the correction version or development level (“Change Level Indicator”). Here, the higher the letter in the alphabet, the more up to date a given part is. For components with embedded software, it signifies the release status.
