Tesla EPC online — genuine Tesla parts by VIN

How do I log in to Tesla EPC?

Type epc.tesla.com and you land on parts.tesla.com, the catalog Tesla heads Genuine Tesla Parts. Browsing needs no login. Choose your country, the model and the generation, and you walk down to exploded diagrams with Tesla part numbers, descriptions and prices beside each line. We checked this signed out on 24 September 2026.

The account comes in when you buy. In the US view, pressing Add To Cart sends you to Tesla’s sign-in page, and Tesla’s parts and tools page on service.tesla.com says you order with a free Tesla Account. In the UK view the same diagrams showed prices in pounds and no Add To Cart button, so what you can order depends on your market. Shops can register a Tesla Business Account for dedicated support and, on parts bought for resale, tax-exempt purchasing on qualifying orders. Only professionals registered with a vehicle security accreditation organization can configure parts that touch vehicle security or need programming.

service.tesla.com is Tesla’s service portal. Its service manuals, wiring diagrams and do-it-yourself guides are free, and the Model 3 service manual opened without an account. Tesla charges for its diagnostic software instead: one licence covers Toolbox, Service Mode Plus and Theory of Operation, sold by the day, month or year, at $75, $150 and $700 on the US site.

Why a Tesla VIN matters more than a model year

Every other manufacturer in this catalog gives you a fixed point to navigate by: a model year, a facelift, a platform code. Tesla does not work that way. Changes go into production when they are ready, so a Model 3 built in March and one built in June are simply different cars in places that matter, and neither the badge nor the paperwork announces it. Tesla’s own catalog splits each model into a few generations bounded by months, and one generation can span years: in the US view, the first Model 3 generation runs from June 2017 to December 2023.

The practical effect at a parts counter is that experience stops helping. A technician who has fitted the same control arm on twenty Model 3s cannot assume the twenty-first takes it. The VIN is the only thing that resolves which revision of a component that specific car left the factory with, which is exactly what the catalog is for.

It also means a superseded number matters more here than elsewhere. Tesla revises parts frequently and the replacement often carries a changed variant code rather than an obviously new number, so reading the current chain rather than an old note is the difference between one order and two.

Reading a Tesla part number

Tesla numbers are unusually informative once you know the shape. A number such as 1044300-00-A splits into three blocks: a seven-digit base identifying the component, a two-digit variant, and a letter revision.

The base number stays put across the life of a component. The variant digits are where Tesla records the running changes described above, and the trailing letter steps A, B, C as the part is updated. So two numbers that differ only in the last blocks are the same component at different points in its life, and the one the catalog shows for your VIN is the one that belongs on the car.

That structure is also a quick sanity check on a quote. If a supplier offers a number whose seven-digit base does not match the component you asked about, the conversation has gone wrong before any money moved.

The independent workshop problem

Tesla sells parts itself, without a franchised dealer network. Tesla lists the routes: online at parts.tesla.com, over the counter at a Tesla Service Center, through affiliates such as Tesla Approved Collision Centers that resell parts, and from independent distributors.

That leaves the identification work with the workshop. Being able to name the exact part, with its number and the diagram it sits in, is what makes the job quotable and the order possible, whichever of those routes you buy through.

Body and structural work needs checking first

Tesla mixes aluminium and steel and, on newer platforms, uses large single-piece structural castings at the front and rear. That has a direct consequence for collision work: some damage that would be a straightforward section repair on a conventional bodyshell is not repairable the same way, and the catalog is where you find out what Tesla actually publishes as a replaceable part.

Checking that before committing to an estimate saves the conversation nobody wants to have halfway through a repair. The parts list is the honest answer to whether a job is a panel replacement or something considerably larger.

What comes across the counter

One login covers the Tesla range. The work that reaches independent shops most often is ordinary rather than exotic:

• Suspension: control arms, bushes, links, subframe hardware
• Brakes: calipers, discs, seized slide hardware from regenerative braking
• Body: bumpers, lighting, glass, mirror and trim assemblies
• Interior: door hardware, seat components, trim panels
• Thermal: coolant pumps, valves, heat pump components
• Charge port assemblies and their wiring

Tesla’s free catalog or VINsearch: which one you need

Most pages on this subject still skip it: Tesla made its parts catalog public. You can browse the breakdowns for Model S, Model 3, Model X, Model Y and Roadster without a login, and the US view adds Cybertruck.

The limits appear when you try to act on what you found. Ordering takes a Tesla Account, the Add To Cart button appears in some markets and not in others, and only accredited professionals can configure parts that touch vehicle security. Tesla decides what it sells and to whom, which is a different question from what a workshop can fit.

So if you run a Tesla-only operation and ordering works in your market, use Tesla's catalog. Nobody should pay for a second route to the same numbers. The arithmetic changes when Teslas are a slice of your week rather than all of it. A shop that also sees a Golf, a Sprinter and a Haval runs one login, one VIN habit and one supersession check across everything on VINsearch, from a $5 Day Pass, and the Tesla data arrives inside that instead of in a separate account with its own rules.
