The GM Global Electronic Parts Catalogue (EPC) is the official, factory-authorised software solution used by General Motors dealerships and licensed repairers worldwide to identify, locate, and order genuine GM parts.
Unlike generic aftermarket catalogues (like those from NAPA or AutoZone), the GM EPC is the source of truth. It is the same system that GM dealership parts managers use to look up components for everything from a 1969 Camaro to a 2024 GMC Hummer EV. The database interfaces directly with GM’s Global Logistics system, ensuring that part numbers, supercessions (replacements for discontinued parts), and pricing are real-time and accurate. gm global epc -electronic parts catalogue-
For the DIY home mechanic restoring a 1987 Monte Carlo SS? No – stick to free VIN decoders and Summit Racing. For a professional shop, a fleet manager, or a salvage yard? Absolutely yes.
The GM Global Electronic Parts Catalogue is the only tool that guarantees part accuracy, leverages GM's global logistics for availability, and respects the engineering complexity of modern vehicles. It eliminates the dreaded "This part doesn't fit" conversation.
If you service GM vehicles daily, budget for the subscription. Training your technicians to use the EPC fluently will reduce parts return rates by over 70% and increase customer satisfaction because the car goes out right, the first time. In the digital age of auto repair, the GM Global EPC isn't just a catalogue—it's your diagnostic partner in repair.
Disclaimer: GM Global EPC access and pricing are subject to change. Always verify current subscription fees via GM GlobalConnect or your regional GM distributor.
The GM Global Electronic Parts Catalogue (EPC) is a powerful, web-based tool used by authorized dealerships, repair shops, and parts specialists to identify, locate, and order genuine parts for General Motors vehicles worldwide (including Chevrolet, GMC, Cadillac, Buick, Holden, Opel, and Vauxhall).
Note: Access to the official GM Global EPC is generally restricted to commercial accounts and requires a paid subscription, often through portals like GM GlobalConnect or authorized third-party platforms. 1. Getting Started: Access & Login
Official Access: Dealerships and authorized repairers use GM GlobalConnect to access the EPC. You will need a user ID and password.
Subscription Alternatives: Independent shops often use third-party subscription services (e.g., PartsBridge or Infomedia) that host the GM EPC data.
Browser Compatibility: The system often requires specific browser settings (usually Internet Explorer or Chrome with IE emulation) to manage active content. 2. Vehicle Identification (VIN Search)
The most efficient way to use the EPC is by using the Vehicle Identification Number (VIN).
Enter VIN: Locate the 17-character VIN on the vehicle dash or door jamb and enter it into the "VIN" field. The GM Global Electronic Parts Catalogue (EPC) is
Verify Vehicle: The system will decode the VIN, showing you the exact year, make, model, engine, and transmission type.
Filter Parts: Once the VIN is loaded, the catalogue automatically filters out parts that do not fit your specific vehicle, preventing ordering errors. 3. Searching for Parts You can find parts in the EPC through several methods:
Search by Part Number: If you have an old part number, enter it to see its price, description, and if it has been updated to a new number (supersession).
Search by Description: Type the name of the part (e.g., "alternator," "brake pad") to find it in the catalogue.
Visual Search (Group Index): Use the illustrated diagrams to locate parts visually. This is ideal when you are unsure of the exact name. 4. Understanding Catalog Diagrams
Exploded Views: The EPC shows diagram layouts ("exploded views") that show how components fit together.
Reference Numbers: The numbers on the diagram correspond to the part number list below it.
Zoom & Highlight: Use the toolbar to zoom in on complex areas and highlight parts. 5. Identifying Part Numbers & Notes
Part Number (P/N): The 8-digit or 10-digit number needed for ordering.
Supersession: Note if the part number has been replaced by a newer one.
Usage Notes (RPO Codes): Look for footnotes regarding Regular Production Option (RPO) codes. For example, a part may only fit vehicles with "Option Code FE2" (suspension type). 6. Creating a Parts List/Order What is the GM Global EPC
Add to List: As you identify parts, select them to add to your current "List" or "Quote."
Check Stock/Pricing: If connected to your local dealer network, you can check real-time pricing and availability.
Export/Order: Export the list to a PDF or send it directly to a GM dealer for ordering. Tips for Efficient Usage
Check for Supersessions: Always ensure you are using the latest part number, as old numbers might not be available or might have been upgraded.
Verify RPO Codes: Use the RPO list (usually found on the glove box or driver's door) to confirm specific vehicle features (e.g., paint codes, engine type) mentioned in the notes.
Save Vehicle Sessions: You can save your search session to return to it later.

Are you using a dealer portal (GlobalConnect) or a third-party tool?
If you have a VIN, I can guide you through the process for that specific vehicle.
For years, the standalone version of GM EPC ran on Java-based architecture.
❌ Ignoring RPOs – ordering a radiator for a cooling package you don’t have.
❌ Using the wrong model year – mid-year changes happen; use VIN, not assumed year.
❌ Assuming supersession = better fit – some superseded parts require additional clips or modules.
❌ Not checking “Part may be discontinued” – if the EPC shows no price, call dealer first.
❌ Forgetting fasteners – diagrams often show bolts separately; they are not included with the main part.
