Wingtech Technology is one of the world's largest smartphone/laptop ODMs, and its MAC footprint spans two IEEE registrants that should be aliased to one family: "Wingtech Mobile Communications Co.,Ltd" (8 prefixes; MA-L + MA-M) and "Wingtech Group (HongKong）Limited" (6 prefixes; MA-L). A verified sample is 14:16:9E (Wingtech Group HongKong, MA-L). The Hong Kong entity lists a Tsim Sha Tsui address, while Wingtech's HQ is in Jiaxing, Zhejiang, China. These OUIs appear on smartphones, tablets, laptops, and IoT devices built for many major phone brands, so a Wingtech OUI may appear on a device sold under another brand. Two factual corporate notes are relevant: Wingtech acquired Nexperia (the former NXP Standard Products business) in 2018–2019 — though Nexperia's discrete semiconductors are a separate matter from MAC OUIs — and Wingtech was added to the US Bureau of Industry and Security (BIS) Entity List effective 2 December 2024 (Federal Register final rule 2024-28267). In a related development, the Dutch government placed Nexperia under temporary external management on 7 October 2025 under the Goods Availability Act. These are stated as factual regulatory context, not advocacy. For triage, a Wingtech OUI indicates a Wingtech-built handset, tablet, or laptop that ships under a major phone brand, so do not infer the retail brand from the OUI.
- IEEE assignment
- two entities — "Wingtech Mobile Communications Co.,Ltd" (8; MA-L + MA-M), "Wingtech Group (HongKong）Limited" (6; MA-L) [Confirmed] — IEEE MA-L/MA-M
- Registry / block size
- Mobile Communications MA-L + MA-M; Group HongKong MA-L [Confirmed] — maclookup.app (IEEE-sourced)
- HQ / country
- Group HongKong entity lists a Tsim Sha Tsui, Hong Kong address; Wingtech HQ Jiaxing, Zhejiang, China [Confirmed for HK entity] — maclookup.app
- Company status
- active; publicly traded (Shanghai) since 2015; acquired Nexperia 2018–2019; added to US BIS Entity List effective 2024-12-02 (Federal Register 2024-28267); Dutch government placed Nexperia under temporary external management 2025-10-07 [Confirmed] — federalregister.gov

- Special note
- Phone-ODM "OUI ≠ brand" case. Nexperia (discrete semiconductors) is a separate matter from Wingtech's MAC OUIs. Regulatory (factual, not advocacy): BIS Entity List effective 2024-12-02; Nexperia under Dutch temporary external management since 2025-10-07. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]

- A Wingtech OUI indicates a Wingtech-built handset/tablet/laptop that ships under a major phone brand — do not infer the retail brand from the OUI.
