Wanan Hongsheng Electronic Co.Ltd — 5 prefixes (MA-L)

Wanan Hongsheng Electronic Co.Ltd holds five separate MA-L (24-bit OUI) blocks registered to an identical address in Wan'An County, Ji'An City, Jiangxi province, China (postal code 343800): 28:04:C6, 5C:56:A4, AC:AD:EF, B0:38:E2, and E0:9D:FA. Holding multiple independent OUI-24 assignments under one registrant string is itself a substance signal — bare shell registrations almost never accumulate five blocks. The address maps to a named production base of Jiangxi Lianchuang Hongsheng Electronic Co., Ltd, a Nanchang-headquartered consumer-electronics ODM whose own company profile lists "modern production bases in Nanchang, Fuzhou, Ji'an, Taihe, Wan'an, Zhengzhou, and Luzhou" — i.e. Wan'an is one of its stated plants. Corporate-directory listings (D&B, PatSnap) describe the group as an active manufacturer with roughly 7,000 employees, 300–400 R&D engineers, and 112 patents, producing Bluetooth TWS earbuds and charging cases, smart watches, smart glasses, Bluetooth speakers, NFC rings, and GaN chargers/power banks — exactly the class of consumer BLE/Wi-Fi wearables that requires MA-L OUI blocks for MAC addressing. A concrete product tie exists at the group level: model LCTWS005 (TWS earbuds) ships inside HONOR CHOICE-branded earbuds, and FCC grantee filings under "Jiangxi Lianchuang Hongsheng Electronic Co, L T D" show an active filing history from 2016 through 2024, including FCC ID 2AIEKEBT-2100 (2016) and 2BAPQ-LCTWS005 (2023). The identity link between the bare registrant string "Wanan Hongsheng Electronic Co.Ltd" and the parent group's product/FCC evidence rests on the address match plus the parent's own statement about its Wan'an plant, not a primary source using the short registrant string verbatim — so the corroboration is treated as Likely rather than Confirmed. IEEE's public MA-L registry publishes no assignment or registration date field; no date is claimed for any of the five blocks, and third-party aggregator "date registered" values are noted as non-authoritative database artifacts, not IEEE facts.

IEEE assignment

5 prefixes → Wanan Hongsheng Electronic Co.Ltd, registered Wan'An County, Ji'An City, Jiangxi, CN 343800 [Confirmed] — the IEEE MA-L registry (1074, 7790, 32251, 18381)

Registry / block size

MA-L (24-bit OUI) only; no MA-M or MA-S entries found for this org [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry, the IEEE MA-S registry

HQ / country

Wan'An County, Ji'An City, Jiangxi province, CN 343800 (registry address) [Confirmed] — the IEEE MA-L registry

Prefix set

28:04:C6, 5C:56:A4, AC:AD:EF, B0:38:E2, E0:9D:FA — four of the five share an identical registrant-name and address string; AC:AD:EF (the IEEE MA-L registry) carries a variant registrant string (double space between "Hongsheng" and "Electronic") and a variant/incomplete address string, flagged as a data-quality variant rather than a distinct organization

[Confirmed] — the IEEE MA-L registry

Third-party cross-reference

Wireshark the Wireshark manufacturer database file independently lists the same 5 prefixes short-named "WananHongshe" / "Wanan Hongsheng Electronic Co.Ltd," consistent with the IEEE MA-L registry, no additional prefixes found [Confirmed] — the Wireshark manufacturer database

Company substance

address maps to a named production base ("Wan'an") of Jiangxi Lianchuang Hongsheng Electronic Co., Ltd, a Nanchang-headquartered consumer-electronics ODM (~7,000 employees, 112 patents per D&B/PatSnap); no primary source uses the exact short registrant string verbatim, so this is corroborating-but-not-1:1-confirmed [Likely] — https://www.globalsources.com/jiangxi-lianchuang/company-profile_6008852373474.htm, https://www.dnb.com/business-directory/company-profiles.jiangxi_lianchuang_hongsheng_wanan_electronics_co_ltd.e9f0143176f4c0c70b59f6ac0f5e1529.html, https://discovery.patsnap.com/company/jiangxi-lianchuang-hongsheng-wanan-electronics/

Device types / product context

Bluetooth TWS earbuds and charging cases, smart watches, smart glasses, Bluetooth speakers, NFC rings, GaN chargers/power banks; model LCTWS005 (TWS earbuds) used inside HONOR CHOICE-branded earbuds [Likely] — https://device.report/jiangxi-lianchuang-hongsheng-electronic/lctws005, https://manuals.plus/honor-choice/x5-lite-earbuds-manual, https://www.globalsources.com/jiangxi-lianchuang/homepage_6008852373474.htm

Regulatory filings

FCC grantee filings under "Jiangxi Lianchuang Hongsheng Electronic Co, L T D," active 2016–2024, including FCC ID 2AIEKEBT-2100 (2016) and 2BAPQ-LCTWS005 (2023, matches the TWS earbuds model above) [Likely] — https://fcc.report/company/Jiangxi-Lianchuang-Hongsheng-Electronic-Co-L-T-D

Security context

no CVEs or published advisories found under either "Wanan Hongsheng" or "Lianchuang Hongsheng" — this is an ODM/component maker whose modules ship inside other brands' products, so treat as unconfirmed-absence, not confirmed-clean [Unknown]

Assignment date

Unknown / not applicable — IEEE's public the IEEE MA-L registry publishes no date column (only Registry, Assignment, Organization Name, Organization Address); no date is attributed to IEEE for any of the 5 blocks. A third-party aggregator (maclookup.app) shows a "registered 23 May 2016" style value for this vendor string, but that is a database-crawl artifact, not an IEEE fact, and is not recorded here

[Confirmed absence of an IEEE date] — https://maclookup.app/vendors/wanan-hongsheng-electronic-co-ltd (cited only to flag it as non-authoritative)

Company status

active — group has an ongoing FCC filing history through 2024 and a live Global Sources manufacturer profile [Likely] — https://www.globalsources.com/jiangxi-lianchuang/homepage_6008852373474.htm
