What are the Ford parts numbering system?

Ford parts numbers are unique alphanumeric codes that identify Genuine Ford Parts across catalogs and dealers; they help ensure you get the right part for the right vehicle and simplify cross-referencing.

These numbers are used in official Ford catalogs such as FordParts.com in North America and the Electronic Parts Catalog (ETK) in other regions. They typically consist of a prefix identifying the part family or program, a base sequence that identifies the component, and an optional suffix that indicates revision, packaging, or regional qualifiers. The rest of the article explains what those numbers look like and how to use them in practice.

Structure of a Ford part number

Most Ford part numbers follow elements that you will encounter in most parts: a prefix or family code, a base numeric sequence, a suffix for revision or packaging, and sometimes regional qualifiers. The elements help identify the part type, vehicle compatibility, and revision level.

• Prefix or family code (identifies the part family or program)


• Base numeric sequence (the core part identity)


• Suffix (revision, packaging, or region)


• Optional market or application qualifiers (sometimes included as part of the prefix or suffix)

Understanding these elements helps you locate the correct part in Ford catalogs and cross-reference with aftermarket numbers.

Regional variations and catalog formats

In North America you will primarily encounter FordParts.com references, while Europe and other regions use the Electronic Parts Catalog (ETK) with region-specific prefixes and conventions. Global parts are mapped to regional formats but usually correspond to the same base component.

How to read and use Ford part numbers

To use the numbers effectively, follow these steps from identification to ordering:

1. Find the part number on the part itself, packaging, invoice, or the relevant Ford catalog entry.


2. Identify the segments (prefix, base, suffix) by noting hyphens or catalog grouping; note that some markets may present numbers without hyphens.


3. Cross-reference the number in the official Ford catalog (FordParts.com or ETK) to confirm fitment for your vehicle by model year, trim, and VIN if required.


4. Check whether there is a superseding or revised part number and verify packaging or dealer stock.


5. If the exact number is unavailable, use the catalog’s cross-reference tool to find equivalent or updated numbers or contact a dealer parts desk.

Tip: Always verify compatibility with your vehicle’s VIN and consult the latest catalog to ensure you are ordering the correct revision and packaging.

Where to find official information

Rely on official sources to avoid errors and ensure correct parts across markets and model years:

• FordParts.com (North America) – official online catalog and ordering portal


• ETK (Electronic Parts Catalog) – regional catalogs in Europe and other markets


• Ford dealer parts desk – in-person cross-reference and ordering assistance


• Vehicle-specific service manuals or assembly drawings – for component identification and installation context

Using official sources helps ensure accuracy, especially when parts cross multiple model years, regions, or production lines.

Cautions and best practices

Ford updates part numbers as parts are revised, superseded, or discontinued. Always verify the current number in the latest catalog and be mindful of VIN-specific versus non-VIN-specific parts. Regional differences can affect availability and nomenclature, so cross-check across the appropriate catalog for your market.

VIN-specific vs. non‑VIN parts

Some parts are VIN-specific and must match a particular vehicle configuration. The catalog will indicate compatibility, and you should verify by entering the VIN where prompted or by checking the vehicle’s build data in the parts entry.

Obsolete parts and supersession

Parts may be superseded by newer numbers as engineering changes occur. When a number is superseded, the catalog will usually show the current replacement and any notes about compatibility or discontinued status.

Summary

Ford’s parts numbering system is designed to provide a precise, cross-referenceable method to identify Genuine Ford Parts across global markets. By understanding the core elements—prefix/family code, base number, and suffix or regional qualifiers—customers can navigate FordParts.com, ETK, and dealer resources to verify fitment, confirm revisions, and order correctly. Always consult official catalogs for the latest part numbers and cross-reference tools to avoid mismatches and ensure proper vehicle compatibility.

How to read Ford part numbers?

To read a Ford part number, break it down into three sections: the prefix, the basic part number, and the suffix. The prefix (e.g., C7AZ) indicates the decade, year, model, and engineering department. The basic part number (e.g., 8200) identifies the component's function. The suffix (e.g., -A) indicates the level of design change or revision. 
Decoding the part number
CodeExample: C7AZ-8200-ACode copied!

Section	Example Code	Meaning
Prefix	C7AZ	Decade: C = 1960s Year: 7 = 1967 Model: A = Full-size Ford/Galaxie Engineering: Z = Ford Service Parts
Basic Part Number	8200	Identifies the specific part, such as a grille. (Refer to a parts manual or chart for specific codes, e.g., 8200 for grille, 9425 for intake manifold)
Suffix	-A	Indicates the level of design change. -A is the first revision, with later letters (skipping I) indicating further changes

Important considerations

• Casting vs. Service Numbers: Be aware that the number cast directly onto a part is often a "casting number," which is different from the "service part number" used to order a replacement. 
• System evolution: Ford's numbering system has changed over time. Codes for decades and models can vary, especially for newer vehicles. 
• Interchangeability: A part's original number might remain the same even if the part was later used on different models. 
• Hardware: This decoding system does not apply to standard hardware like bolts or nuts. 

What are the base numbers for Ford parts?

Ford base part numbers are the central identifying number within a larger part number, typically 4-5 digits, which indicate the specific part and its function. For example, a base number of 1000 is for wheels and hubs, while 2000 is for the braking system. These base numbers are a key component of a full Ford part number, which also includes a prefix (indicating the decade, year, car line, and engineering group) and a suffix (indicating change level, revision history, or application).
 
Breaking down the base number

• Function: The base number itself tells you what the part is, regardless of its specific application on a particular vehicle. 
• Examples:
  • 1000: Wheels and hubs 
  • 2000: Brakes 
  • 3000: Suspension and steering 
  • 4000: Driveshaft and differential 
  • 5000: Exhaust system 
  • 6000: Engine 
  • 7000: Transmission 
  • 8000: Cooling system 
  • 9000: Fuel and emission systems 
• Left/Right: The last digit of the base number can indicate the side of the vehicle. 
  • Odd numbers: are for the left (driver's) side. 
  • Even numbers: are for the right (passenger's) side. 

Other parts of the full Ford part number

• Prefix: The first four digits of the number specify the part's history. 
  • The first digit is the decade the part was introduced. 
  • The second digit is the year within that decade. 
  • The third digit represents the car line (e.g., Mustang, Falcon). 
  • The fourth digit specifies the engineering group that developed it. 
• Suffix: The letters at the end indicate changes or specific details. 
  • 'A': is the original design, and subsequent letters ('B,' 'C,' etc.) indicate revisions. 
  • Suffixes can also denote specific applications, colors, or finishes. 

How do I identify my Ford parts?

You can identify Ford parts by checking the part itself for the Ford, Motorcraft, or Omnicraft logo and a unique part number. To find the correct part, use an online parts catalog or dealer website and search by vehicle make, model, year, or VIN, or check your owner's manual.
 
How to identify and find a Ford part

• Look for official branding: Genuine Ford parts will have the Ford logo, Motorcraft, or Omnicraft branding on the part or its packaging. 
• Find the part number: Each genuine part has a unique part number printed on it. 
• Search online: Use official Ford parts websites or other online parts stores and enter your vehicle's make, model, year, or VIN to find the exact part you need. 
• Use a VIN decoder: Websites with a Ford VIN lookup tool can help determine your vehicle's specific features to ensure part compatibility. 
• Consult your owner's manual: Some common parts, like spark plugs and wiper blades, may have their part numbers listed in the "Specifications" section of your owner's manual. 
• Check with a dealer: Contact a Ford dealer for assistance in identifying and ordering the correct part for your vehicle.
