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]
- Related vendors
- BYD Company (parent), BYD Auto / BYD Semiconductor (siblings); peers Hon Hai/Foxconn, Luxshare, Jabil
- 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).
