BYD Electronic — multiple entities (MA-L); EMS/ODM, OUI ≠ brand on the box (distinct from BYD Auto)
Summary
- // what this is
- BYD Precision Manufacture is registered to MAC prefix
90:20:3Aand 3 more in the IEEE OUI database. When a device's MAC address begins with90:20:3A, that block was registered by BYD Precision Manufacture — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A BYD Precision OUI identifies the contract manufacturer; the finished device is very often sold under a completely different consumer brand — treat as 'made by BYD's EMS arm,' then classify by other signals (DHCP hostname, model strings, mDNS).
About this vendor.
BYD Electronic's MAC footprint spans several IEEE registrant strings that should be aliased to one family: "BYD Precision Manufacture Company Ltd." (~3 blocks), a separately spelled "BYD Precision Manufacture Co.,Ltd" record (holds 90:20:3A), and "BYD COMPANY LIMITED" (1 block — the parent). Verified samples include 90:20:3A, BC:23:92, 18:3B:D2, and 98:BB:1E. The registered addresses are in Shenzhen, Guangdong (e.g., No.3009 BYD Road, Pingshan), with one block listing a Shanghai/Pudong address. These OUIs appear on smartphones, tablets, IoT, smart-home, game hardware, and communication equipment assembled for other brands. BYD Electronic (International) Co Ltd — Hong Kong-listed, ticker 00285 — is the EMS/ODM subsidiary of BYD Company, distinct from BYD Auto (the electric-vehicle business); it acquired several Jabil China manufacturing operations (definitive agreement 2023-09-26, completed 2023-12-29) and has been part of the iPhone supply chain. For triage, a BYD Precision OUI identifies the contract manufacturer, and the finished device is very often sold under a completely different consumer brand, so treat it as "made by BYD's EMS arm" and classify by other signals.

- Special note
- EMS/ODM "OUI ≠ brand" case; the EMS arm (BYD Electronic) is distinct from BYD Auto (EVs). At least three differently-spelled IEEE registrant strings exist — alias them for matching. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]
