BYD EPC is the online BYD Portal catalog for BYD, available worldwide through VINsearch. Decode any BYD VIN, open the exact assembly diagram, and read off the genuine OEM part number — all in the browser, with no desktop install.
What is BYD EPC?
BYD EPC is the electronic parts catalog BYD technicians and parts specialists rely on to identify genuine components. Built on BYD Portal — BYD's factory parts data reaching back to vehicles from the marque's earlier model years — it maps every vehicle to its exact build via the VIN.
As an EV-focused marque, BYD's catalog emphasises high-voltage architecture: battery modules, inverters, thermal management and the connectors and harnesses that aftermarket lookups simply do not document.

BYD EPC vs free viewers and aftermarket lookups
Free single-brand viewers and aftermarket cross-reference tools are fine for a rough guess, but they lag behind factory data and miss supersessions. BYD EPC reads from BYD Portal directly, so the number you see is the number BYD currently ships — which is exactly what prevents wrong-part returns.
What a BYD part number looks like
Numbers issued by BYD follow one house format, so the shape of a number tells you who issued it before you open a diagram.
FormatBYD-3501010
A BYD prefix followed by a seven-digit group number using the same national group codes as other Chinese makers.

Frequently asked questions
What is BYD EPC used for?
BYD EPC is used to identify genuine BYD parts by VIN: it shows exploded diagrams, OEM part numbers, quantities and supersession chains for every BYD model and year.
Do I need to install anything?
No. BYD EPC on VINsearch is web-based (no install). You log in from any browser — there is no desktop software, dongle or dealer credential required.
Does BYD EPC include older BYD models?
Yes. Because it is built on BYD Portal, the catalog includes historic BYD models alongside current ones, with factory supersessions so discontinued numbers resolve to their current replacements.
Is it the official catalog?
VINsearch provides online access to the official BYD Portal dataset. The data is the manufacturer's; VINsearch is the independent access platform that makes it usable in the browser worldwide.
