Tesla Parts Catalog by Model: Part Numbers, EPC Diagrams and Parts Lookup Guide
1. What Is the Tesla Parts Catalog?
The Tesla Parts Catalog refers to a digital system that provides detailed schematics, part numbers, and compatibility information for Tesla vehicles. It’s primarily available through Tesla’s Electronic Parts Catalog (EPC), which is used by Tesla service technicians, approved body shops, and (in some regions) the general public.
What Does the Tesla Parts Catalog Include?
The Tesla Parts Catalog contains:
- Exploded diagrams of Tesla components (like doors, suspension, or battery systems)
- Official OEM part numbers
- Part names and quantities
- VIN-based compatibility guidance
This resource helps identify which part fits which model, year, and trim, ensuring precision in repairs and upgrades.

Who Is the Tesla Parts Catalog For?
The Tesla Parts Catalog serves:
- Tesla owners who want to understand their vehicle’s build or plan upgrades
- Independent repair shops working on Teslas
- DIY enthusiasts performing self-repairs or cosmetic swaps
- Auto parts resellers or those searching for OEM part numbers
Note: In many countries (including the U.S. and Europe), Tesla now allows limited public access to EPC systems to comply with right-to-repair legislation.
Public Access Limitations
While the Tesla EPC is technically accessible, full functionality—such as pricing or ordering—is usually restricted to:
- Tesla Service Centers
- Tesla-certified body shops
- Approved third-party repair partnersIn most cases, owners can view diagrams and part numbers, but cannot place direct orders through the catalog.
Why the Tesla Parts Catalog Matters
Knowing how to navigate the Tesla parts catalog helps in:
- Accurate self-diagnosis of what needs replacing
- Finding parts on eBay or salvage sites using the exact OEM number
- Communicating with Tesla Service more efficiently
- Avoiding wrong orders for parts that don’t match your trim or VIN
For Tesla owners involved in DIY upgrades, insurance claims, or collision, this Tesla Parts Catalog is an invaluable resource.
2. How to Access the Tesla EPC and Find the Right Part Number
Tesla’s Electronic Parts Catalog (EPC) is a vital resource for anyone needing to identify or order genuine Tesla parts. While access is somewhat restricted, you can view part diagrams and numbers, especially if you’re located in a region where Right to Repair legislation applies.
How Do You Access the Tesla Parts Catalog (EPC)?
Tesla’s EPC is hosted on their service portal.
However, you may need to create a Tesla Service account or log in with a Tesla ID to gain full access. In certain regions, like the EU or Canada, diagrams are more openly accessible due to legal requirements. In the U.S., access can be more limited for the general public, but part numbers and visuals are often viewable.
Pro Tip: Use a desktop or tablet for full diagram visibility, and check your region’s Tesla policy regarding EPC access.
How to Find the Right Part Number
Once inside the EPC, follow these steps:
Step 1: Select Your Vehicle
Choose your Tesla model (Model 3, Y, S, or X)
Select the year and drive configuration (e.g., RWD, Dual Motor, Performance)
Step 2: Use Your VIN (Vehicle Identification Number)
Entering your VIN helps filter diagrams to show only compatible parts
Tesla parts can vary across trims and manufacturing dates, so using VIN is key to accuracy
Step 3: Browse by Part Category
Tesla Parts Catalog include:
Exterior & Body (bumpers, glass, doors)
Interior Trim & Displays
Drivetrain & Suspension
Battery, Cooling & HVAC
Electrical & Autopilot
Clicking a Tesla Parts Catalog reveals exploded-view diagrams.
Step 4: Identify the Part Number
Each component in the diagram is labeled with:
Part number (e.g., 1044234-00-B)
Quantity required
Brief description (e.g., “Trim – Center Console, Matte Black”)
Example: Finding a Model Y Frunk Seal
1. Log in to service.tesla.com
2. Choose Model Y → 2023 → Dual Motor
3. Navigate to Frunk Assembly → Front Compartment Seals
4. Find part number: 1497356-00-A (Frunk perimeter seal)
Use this number to:
Search for compatible aftermarket parts
Things to Watch Out For
Tesla part numbers may look similar but differ by letter suffix, which indicates version changes or compatibility.
Some diagrams list “Service Kits” — these include multiple pieces (e.g., clips, bolts) required for one repair.
Ordering the wrong part number without VIN matching could result in fitment issues.
