Qingdao GoerTek Technology Co., Ltd. — 2 prefixes (MA-L)

This vendor holds two IEEE MA-L (24-bit OUI) blocks — 00:13:8A and B4:67:E9 — both registered to the identical org string "Qingdao GoerTek Technology Co., Ltd." but at two different Qingdao addresses (Room 605, Innovation Building, Hi-tech Industrial Park for 00:13:8A; 5F, No.3 Building, Fortune Center for B4:67:E9), suggesting a relocation between the two assignment events rather than two distinct entities. Independent web research corroborates this is a named, identifiable company — a documented subsidiary of Goertek Inc. (Shenzhen-listed, 002241), founded 2014-08-14 and headquartered in Qingdao — with a real patent portfolio (dozens of USPTO/EPO filings) rather than a bare single-OUI shell. Goertek is the world's largest XR/VR-AR ODM and a major TWS-earbud and acoustic-module manufacturer for Apple, Samsung, Sony, and Meta, which plausibly ties these prefixes to Wi-Fi/Bluetooth audio and wearable hardware, though no source names a specific product for either exact block. This entity is legally distinct from the already-DONE sibling registrant "Qingdao Goertek Horizons Tecnology Co.,LTD" and from the other Goertek-family IEEE registrations, none of which should be merged with it.

IEEE assignment

2 prefixes → "Qingdao GoerTek Technology Co., Ltd." (identical org string on both blocks) [Confirmed] — the IEEE MA-L registry, :35583

Registry / block size

MA-L (24-bit OUI); 2 IEEE prefixes [Confirmed] — the IEEE MA-L registry; no MA-M (the IEEE MA-M registry) or MA-S (the IEEE MA-S registry) block matches this exact org string

Verified prefixes (both MA-L)

00:13:8A, B4:67:E9 [Confirmed] — IEEE the IEEE MA-L registry (lines 9945, 35583)

Addresses

00:13:8A → Room 605, Innovation Building, Hi-tech Industrial Park, Qingdao, Shandong 266061, CN; B4:67:E9 → 5F, No.3 Building, Fortune Center, Qingdao, Shandong 266061, CN — same city/postcode, different building, most plausibly a relocation between assignment events rather than two entities [Confirmed addresses / Likely relocation inference] — the IEEE MA-L registry, :35583

Registration date

none — IEEE publishes no assignment/registration date for OUI blocks; third-party "registration date" scrapes (maclookup.app shows 2005-02-06 for 00:13:8A and 2011-11-26 for B4:67:E9, the former predating the company's own 2014 founding) are database artifacts, not IEEE facts, and are not recorded here [Confirmed] — https://standards-oui.ieee.org/oui/oui.csv (no date column); https://maclookup.app/vendors/qingdao-goertek-technology-co-ltd

Parent / ecosystem

documented subsidiary of Goertek Inc. (Shenzhen: 002241), founded 2014-08-14, HQ'd in Qingdao; Goertek is the world's largest XR/VR-AR ODM and a major TWS-earbud/acoustic-module manufacturer for Apple, Samsung, Sony, Meta, Lenovo; holds a real patent portfolio (~32 USPTO + 12 EPO filings, 47 inventors)

Exact entity relationship

whether this is a wholly-owned Goertek subsidiary vs. a JV, and the precise ownership chain, is Unknown — not confirmed against a primary Chinese business registry or Goertek investor disclosure [Unknown]

Device types

most plausibly Wi-Fi/Bluetooth consumer hardware (TWS earbuds, VR/AR acoustic modules, speakers, wearables) manufactured as ODM — inferred from Goertek's documented product lines, not from any source tying these exact prefixes to a named product

[Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry, the IEEE MA-S registry; /mac/vendor/qingdao-goertek-horizons-tecnology/

Security context

no device-specific CVE or advisory tied to either OUI. Parent-level only: 2025 ASPI reporting on Goertek Inc.'s funding of a UK (Plessey) acquisition — scoped to the parent company, not to devices carrying these specific prefixes [Likely] — https://en.wikipedia.org/wiki/Goertek

Analyst note

a globally-administered address in these blocks identifies genuine Goertek-registered hardware, but many consumer BT/Wi-Fi devices use MAC randomization, so OUI absence does not mean "not Goertek"; don't rely on OUI alone for inventory or access control.
