Sichuan AI-Link Technology Co., Ltd. — ~38-40 prefixes (MA-L)

Sichuan AI-Link Technology Co., Ltd. is a Mianyang, Sichuan-based manufacturer of wireless communication modules, registered to "SICHUAN AI-LINK TECHNOLOGY CO., LTD." across a large set of MA-L (24-bit OUI) blocks — roughly 38-40 prefixes by current third-party snapshots, which makes a single consolidated vendor entry far more useful than dozens of near-identical per-prefix pages. The key context for interpreting these prefixes is that AI-Link is a business-to-business module supplier, not a consumer device brand: its Wi-Fi (Wi-Fi 4/5/6/7), Bluetooth (classic + BLE), Zigbee, UWB, and cellular/LPWAN (NB-IoT, 4G/5G, LoRa) modules are embedded as components inside third-party OEM products — smart-home appliances, IP cameras, industrial IoT sensors, connected vehicles, and retail/medical IoT devices. The practical consequence for network analysts: an AI-Link OUI on a home or enterprise network almost never corresponds to a device branded "AI-Link"; it identifies the radio module inside some OEM product, and the end user typically sees the OEM's brand instead. The company is majority-owned (reported 71.91%) by Sichuan Changhong Electronics Holding Group, a large state-linked Chinese electronics conglomerate, and holds TÜV Rheinland-certified ISO 9001, IATF 16949, and QC 080000 quality systems. No IEEE registration date applies — IEEE publishes none — and the "date registered" values shown by third-party MAC lookup tools (e.g., 15 Feb 2018 on maclookup.app) are database artifacts, not IEEE facts.

IEEE assignment

~38-40 MA-L prefixes → Sichuan AI-Link Technology Co., Ltd., registered Anzhou District, Mianyang, Sichuan, CN [Confirmed] — IEEE oui.csv (local registry cache: P:/networklookup/enrichment/registries/oui.csv; MA-L hits only — no mam.csv/oui36.csv entries)

Registry / block size

MA-L (24-bit OUI, standard large block); ~38-40 IEEE prefixes by current third-party snapshot [Likely on the count] — maclookup.app (count drifts; 38 vs 40 reflects different database snapshot dates, treat as approximate). NOTE: IEEE's public OUI data publishes NO assignment/registration date (oui.csv columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" on third-party tools (e.g., 15 Feb 2018 / updated 12 May 2026 on maclookup.app) is a database artifact, not an IEEE fact.

HQ / country

Anzhou Industrial Park, Mianyang City, Sichuan, CN (registry shows postal codes 622650 and 621000, both within Anzhou District, Mianyang — the discrepancy is a registry data-entry variation). Full address per certification record: A01 Building, 3# Kexing Road, Anzhou Industrial Park, Mianyang City, Sichuan 622650, China [Confirmed] — IEEE oui.csv; certipedia.com/quality_marks/9108641700

Security note

no public CVEs or named security advisories specifically attributed to AI-Link modules were found this pass; no named sanctions, FCC prohibitions, or government advisories against AI-Link found as of June 2026. As a Changhong subsidiary, AI-Link sits within the broader category of Chinese IoT-module suppliers under ongoing US/EU supply-chain scrutiny, but no specific named prohibition was located. Standard IoT hygiene applies: an unrecognized AI-Link MAC on a home network warrants investigation (WPA2/WPA3, disable WPS) [Likely] — vpnstreamer.com.au; ailinkiot.com; trendsprouts.com

Analyst note

An AI-Link OUI identifies the embedded radio module, not a consumer "AI-Link" device — expect the visible product to carry an OEM brand. Large MA-L footprint is consistent with a module vendor shipping radios across many device categories.
