RPO codes is an overview of Regular Production Option codes used to identify factory options, equipment, colors, trims, and configurations on the Pontiac Fiero.
RPO stands for Regular Production Option. General Motors used RPO codes to identify factory-installed equipment, option packages, colors, trims, drivetrain components, and other build information.
Overview
A Fiero's RPO codes can help identify how the car was originally equipped from the factory.
RPO codes may describe items such as paint color, interior trim, transmission, engine, wheels, suspension package, audio system, glass, comfort features, appearance equipment, and other factory-installed items.
The most useful source for the RPO codes assigned to a specific Fiero is the Service parts identification label.

Service Parts Identification label
The Fiero RPO list is found on the Service parts identification label.
This label identifies the equipment and build information assigned to a specific car. It may include regular production options, standard equipment codes, mandatory equipment codes, paint information, drivetrain information, trim information, and other factory build data.
The label is useful when ordering parts, documenting a restoration, verifying original equipment, or comparing the car's current configuration with how it was built.

Not every code is an optional extra
Although RPO stands for Regular Production Option, not every code on the Service Parts Identification label necessarily represents a buyer-selected option.
Some codes may identify standard equipment, mandatory equipment, package content, emissions equipment, paint or trim information, drivetrain components, or other factory build details.
When documenting a specific car, avoid assuming that every listed code was separately ordered by the original buyer.
Common RPO topics
For looking up an unknown code, see:
Topic-specific pages include:
- Engine RPO codes
- Transmission RPO codes
- Paint RPO codes
- Interior trim RPO codes
- Wheel RPO codes
- Tire RPO codes
- Audio RPO codes
- Suspension RPO codes
- Glass RPO codes
Fiero option identification
RPO codes are useful when verifying factory equipment, comparing model-year differences, checking originality, ordering parts, documenting a restoration, or researching production combinations.
For example, RPO codes can help identify:
- Original engine equipment
- Original transmission equipment
- Exterior paint color
- Interior trim color
- Wheel equipment
- Audio equipment
- Glass and mirror equipment
- Air-conditioning or comfort equipment
- Suspension or handling packages
- Appearance packages
RPO codes identify factory build information. They do not necessarily prove what is currently installed on the car decades later.
Many Fieros have been modified, repaired, repainted, engine-swapped, transmission-swapped, or restored. When ordering parts or diagnosing a car, use the RPO label together with physical inspection.
Related topics:
Engine and transmission codes
Engine and transmission RPO codes can help identify how a Fiero was originally equipped.
For transmission identification, the RPO code should be used together with physical inspection of the installed transmission. Fieros are old enough that transmissions may have been replaced, rebuilt, or swapped.

- Transmission RPO codes

Paint and trim
Paint and trim codes are often used together when documenting a car's original appearance.
Paint-related RPO codes can help identify the original exterior color or paint combination. Trim-related codes can help identify the original interior color or trim configuration.
Because Fieros may have been repainted, repaired, or modified, paint and trim codes should be compared with physical evidence on the car.
Related topics:
Audio options
Factory audio equipment can be identified through RPO codes.
For example, the factory upgraded audio system commonly known as Performance Sound is associated with an RPO code.
Related topics:
Build/service codes versus RPO codes
RPO codes should not be confused with separate build-code or service-code lists that may appear in enthusiast documents, assembly references, or parts references.
Some build or service codes may describe component parts, assembly details, service identifiers, model or color differentiations, or parts used as part of standard equipment or option packages. They should not automatically be treated as RPO codes.
Related topic:
Using RPO codes carefully
When using RPO codes:
- Read the code carefully; similar characters can be confused.
- Verify the code against a Fiero-specific or GM-specific source.
- Check model-year applicability.
- Remember that code meanings can vary by GM division, year, or application.
- Do not assume the car still has every original component.
- Use physical inspection when ordering parts for modified or repaired cars.
- Keep a photo of the Service Parts Identification label for reference.
Missing or unreadable RPO label
If the Service Parts Identification label is missing, damaged, faded, painted over, or unreadable, original equipment may need to be verified using other sources.
Possible alternatives include:
- Original window sticker
- Dealer invoice or sales paperwork
- Build sheet, if available
- Previous owner records
- Factory documentation
- Physical inspection
- Paint evidence in hidden areas
- Transmission and engine identification
- Body-number plate information, where applicable
A missing label does not prove the car has been modified, but it removes one of the easiest factory references.
Notes
RPO-code information should be verified carefully. Some codes were used across many GM vehicles, while others may have different meanings depending on year, division, or application.
When possible, RPO-code articles should include the code, description, model-year applicability, related parts, and source of the information.
The RPO label identifies how the car was originally built. It does not necessarily identify every part currently installed on the car.
