Service parts identification label refers to the factory label that lists equipment and build information for a specific Pontiac Fiero.

The label is one of the main factory references for identifying RPO codes, paint information, drivetrain equipment, trim information, and other factory-installed equipment.

Overview

The service parts identification label is one of the most useful factory references on a Fiero. It can help determine how the car was originally equipped from the factory.

The label contains a list of three-character RPO codes. These codes identify factory options and equipment such as paint color, interior trim, transmission, audio system, glass, wheels, and other installed features.

Factory service information describes the service parts identification label as a vehicle-equipment identification label used to assist with servicing and determining replacement parts. The label includes regular production options as well as standard and mandatory options.

The Service Parts Identification label is located in the front compartment area.

Fiero owner documentation identifies the label location as the left front inner fender in the front storage compartment.

Exact label location, label style, and surrounding trim may vary slightly by year, condition, repairs, or previous repainting.

If the label cannot be found, check for signs that the front compartment, inner fenders, or body panels have been repaired, repainted, replaced, or cleaned aggressively.

Information on the label

The Service Parts Identification label may include:

  • Vehicle identification information
  • Wheelbase information
  • Paint information
  • Production options
  • Special equipment
  • Standard or mandatory equipment codes
  • RPO codes

Because the label was intended to assist with service and replacement parts, it can be especially useful when identifying factory-installed equipment.

RPO codes

RPO stands for Regular Production Option. Each RPO code identifies a factory option or equipment item.

Examples of RPO-code areas include:

  • Engine
  • Transmission
  • Paint color
  • Interior trim
  • Audio system
  • Wheels
  • Glass
  • Comfort features
  • Appearance equipment

The Service Parts Identification label is one of the best places to verify which RPO codes were assigned to a specific car.

Standard and mandatory options

Not every code on the Service Parts Identification label necessarily represents an optional extra chosen by the buyer.

Factory service information notes that the label can include regular production options as well as standard and mandatory options.

This means the label can include codes for equipment that was part of the model, required by a package, required for compliance, or otherwise installed as part of the vehicle build.

When documenting a car, avoid assuming that every listed code was a separately ordered option.

Uses

The Service Parts Identification label can be useful for:

  • Verifying factory equipment
  • Identifying paint and trim codes
  • Checking original options
  • Identifying original transmission or drivetrain equipment
  • Researching production combinations
  • Ordering replacement parts
  • Documenting a restoration
  • Comparing the car's current condition with its original configuration
  • Distinguishing factory equipment from later modifications

Paint and trim information

The label can be useful when identifying paint and trim information.

Paint-related codes may help determine the original exterior color or two-tone/fascia-related paint information. Interior trim codes may help identify the original interior color or trim combination.

Because Fieros may have been repainted, repaired, or modified, paint and trim information on the label may not match the car's current appearance.

Transmission and drivetrain identification

The Service Parts Identification label can help identify original drivetrain equipment.

For example, transmission RPO codes can help determine which transmission the car was originally built with.

However, many Fieros have had engines, transmissions, cradles, or other drivetrain parts replaced or swapped. The label identifies factory-installed equipment, not necessarily what is currently installed.

When ordering parts or diagnosing a car, use the label together with physical inspection of the actual installed components.

Previous-owner changes

The presence or absence of equipment on the car today does not always prove how the car was originally built.

Many Fieros have been modified, repaired, repainted, swapped, or partially restored. The Service Parts Identification label can help distinguish factory-installed equipment from later changes.

However, the label should not be used as the only source when the car has been heavily modified.

Missing or damaged labels

If the label is missing, damaged, painted over, faded, or unreadable, factory configuration may need to be verified through other sources such as:

  • 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 that a car has been modified, but it removes one of the easiest factory references.

Build/service codes versus RPO codes

The Service Parts Identification label should not be confused with separate build-code or service-code lists that may appear in enthusiast documents or assembly 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.

Privacy and documentation

When documenting a specific Fiero, include photos of the Service Parts Identification label where possible.

If the image clearly shows a VIN or other owner-identifying information, consider whether the image should be cropped, blurred, or partially obscured before being posted publicly.

For restoration or parts identification, a clear private photo of the full label can be useful even if a public version is partially obscured.

Service notes

When using the Service Parts Identification label:

  • Read codes carefully; some characters can be difficult to distinguish.
  • Photograph the label before it fades further.
  • Verify uncertain codes against a reliable RPO reference.
  • Do not assume every code was a buyer-selected option.
  • Do not assume the current car still matches every listed item.
  • Use physical inspection when ordering parts for modified or repaired cars.
  • Be careful when cleaning near the label.
  • Avoid damaging or removing an original label.

Notes

RPO-code information should be verified carefully. Some codes were used across many GM vehicles, and meanings can vary by year, division, or application.

The Service Parts Identification label is a factory equipment reference, not a complete history of the car. It identifies how the car was built, but not necessarily how it is currently configured decades later.
