Huawei Device Co., Ltd. — 630 prefixes (MA-L)

Huawei Device Co., Ltd. holds 630 MA-L blocks in the IEEE registry, every one assigned to the same address at No.2 of Xincheng Road, Songshan Lake Zone, Dongguan, Guangdong, CN 523808. This is the consumer-focused entity in the Huawei group — distinct in the registry from the much larger parent "HUAWEI TECHNOLOGIES CO.,LTD" (Shenzhen), which carries the carrier and enterprise networking allocations. The Dongguan registrant ships smartphones (Mate, P, and Pura series), smartwatches, fitness bands, wearables, and mobile-broadband dongles, so a Huawei Device OUI seen on a Wi-Fi or LAN scan most likely belongs to a handset or wearable rather than infrastructure — though device class can never be confirmed from an OUI alone. Two registry caveats govern any work here. First, all 630 prefixes are MA-L: there are zero matches for "Huawei Device" in the MA-M (the IEEE MA-M registry) or MA-S (the IEEE MA-S registry) registries, so the entity's entire IEEE presence is 24-bit OUI blocks. Second, IEEE publishes no registration date for OUI or MAC assignments — the public the IEEE MA-L registry carries only Registry, Assignment, Organization Name, and Organization Address columns, so any "date registered" surfaced by third-party lookup tools is a database artifact, not an IEEE fact, and must not be displayed as one. One open item the checker should weigh: the existing DONE entry vendor-huawei-technologies already folds these 630 Huawei Device blocks into its consolidated parent page, naming the subsidiary in its Fields, JSON, and build instruction — so whether this stands as a separate page or merges upstream is an editorial call, not a data gap.

IEEE assignment

630 prefixes → Huawei Device Co., Ltd., registered Dongguan, Guangdong, CN [Confirmed] — IEEE MA-L; 630 is an exact count of "Huawei Device Co" rows in the cached registry

Registry / block size

MA-L (24-bit OUI) for all 630 blocks (~10.6B addresses); zero MA-M and zero MA-S entries [Confirmed] — IEEE the IEEE MA-L registry / the IEEE MA-M registry / the IEEE MA-S registry. NOTE: IEEE's public OUI data publishes NO assignment/registration date (columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" on third-party tools (e.g. a "2019-07-02" first-registration figure) is a database artifact, not an IEEE fact.

HQ / country

No.2 of Xincheng Road, Songshan Lake Zone, Dongguan, Guangdong, CN 523808 [Confirmed] — IEEE MA-L (registry address on all 630 blocks)

Company status

active [Confirmed] — consumer.huawei.com

Device types

smartphones (Mate / P / Pura series), smartwatches, fitness bands/trackers, wearables, mobile-broadband dongles [Confirmed] — consumer.huawei.com, maclookup.app

Notable products

Mate / P / Pura series handsets; Huawei Watch and Band wearables

Verified sample prefixes (all MA-L, Huawei Device Co., Ltd.)

70:66:B9, C4:A1:AE, 38:FC:34, 3C:F6:92, 08:1A:FD, C0:BF:AC [Confirmed] — IEEE the IEEE MA-L registry (first of 630 blocks); cross-checked against standards-oui.ieee.org and maclookup.app

Total prefix count

630 [Confirmed registry count] — exact from cached IEEE the IEEE MA-L registry; a third-party (maclookup.app) snapshot reports "~630" and drifts over time, and IEEE publishes no per-company total

Parent / related entity

parent HUAWEI TECHNOLOGIES CO.,LTD (Shenzhen, CN) holds the carrier/enterprise/networking OUI allocations; the registry lists the two as distinct organizations at distinct addresses (Dongguan vs. Shenzhen) [Confirmed] — IEEE the IEEE MA-L registry. Honor was divested as an independent sub-brand in 2020

Overlap with existing entry

the DONE entry vendor-huawei-technologies already consolidates these 630 Huawei Device blocks under its parent page (named in its Fields/JSON/build instruction) — publishing vendor-huawei-device as a separate page vs. merging upstream is an editorial decision for the checker

[Confirmed] — /mac/vendor/huawei-technologies/

Security / policy context

Huawei-branded devices fall under US Department of Commerce Entity List and FCC equipment-authorization restrictions (Nov 2022); those bans target telecom/networking gear, primarily under the parent HUAWEI TECHNOLOGIES CO.,LTD, but any Huawei OUI may warrant procurement-policy review in regulated or US-government-adjacent environments

Analyst note

a Huawei Device Co. OUI on a network scan most likely indicates a consumer handset or wearable, not carrier infrastructure (that is the parent entity), but device class cannot be confirmed from the OUI alone; in regulated environments any Huawei OUI may trigger policy review regardless of the specific registrant.
