Shenzhenshi Xinzhongxin Technology Co.,Ltd — 8 prefixes (MA-L)

Shenzhenshi Xinzhongxin Technology is a Shenzhen-based OEM/ODM maker of short-range wireless connectivity modules — Wi-Fi, Bluetooth, and BLE — rather than a consumer end-device brand. It holds at least eight MA-L blocks in the cached IEEE registry, filed under close spelling variants of one corporate name: five prefixes (A0:24:42, 04:57:91, 30:63:71, 4C:72:74, 9C:0C:35) read "Shenzhenshi Xinzhongxin Technology Co.Ltd" at Block 3, Dong Huan Industrial Park, Sha Jing Town, Bao'an District, Shenzhen (postal 518104); two (7C:FE:62, 4C:D7:3A) read "ShenZhen XinZhongXin Technology Co.， Ltd" at Building A2 on the same road and postal code; and one (A4:CD:23) reads "Shenzhenshi Xinzhongxin Co., Ltd" at Building A3, postal 518125. FCC filings under Grantee Code 2AG94 confirm the actual product line: Wi-Fi modules, 2.4G Wi-Fi + Bluetooth combo modules, Wi-Fi/BLE modules (model C-2L, 802.11b/g/n 1x1 with classic BT and BLE), and a Bluetooth "anti-lost" tracker. Because these are components embedded by other manufacturers, devices carrying these OUIs in the wild are typically third-party products using this vendor's module, and the module maker's own branding rarely appears on the finished device. No CVEs, botnet activity, or published vulnerabilities were found tied to this vendor by name — an absence-of-evidence null, not a verified clean bill of health, since small Chinese module vendors attract little public security research.

IEEE assignment (primary group)

5 prefixes → "Shenzhenshi Xinzhongxin Technology Co.Ltd", Block 3, Dong Huan Industrial Park, Sha Jing Town, Bao'an District, Shenzhen, Guangdong, CN 518104 [Confirmed] — the IEEE MA-L registry (cached IEEE MA-L)

Registry / block class

MA-L (24-bit OUI); no MA-M (the IEEE MA-M registry) or MA-S (the IEEE MA-S registry) rows matched this registrant by direct grep [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry, the IEEE MA-S registry

Matching prefixes (primary name string)

A0:24:42, 04:57:91, 30:63:71, 4C:72:74, 9C:0C:35 [Confirmed] — the IEEE MA-L registry

Matching prefixes (variant "ShenZhen XinZhongXin Technology Co.， Ltd", Building A2, 518104)

7C:FE:62, 4C:D7:3A [Confirmed] — the IEEE MA-L registry

Matching prefix (variant "Shenzhenshi Xinzhongxin Co., Ltd", Building A3, 518125)

A4:CD:23 — distinct exact org string and address; same registrant family by name similarity but not merged without confirmation [Confirmed assignment; family linkage Likely] — the IEEE MA-L registry

HQ / country

Dong Huan (Donghuan) Industrial Park/Zone, Nanpu Road, Shajing/Xinqiao, Bao'an District, Shenzhen City, Guangdong, China (postal 518104/518125) [Confirmed] — the IEEE MA-L registry

Registration date

Unknown — IEEE publishes NO assignment/registration date in the MA-L/MA-M/MA-S CSVs; the cached the IEEE MA-L registry has no date column. Any third-party "date registered" is a database artifact, never an IEEE fact [Confirmed] — the IEEE MA-L registry

IANA reference

Not applicable — no IANA Reference column exists for OUI/MAC vendor lookups; leave blank [Confirmed] — the IEEE MA-L registry

Security context

Unknown — no CVE, botnet, or vulnerability findings tied to this vendor by name; absence of evidence, not a clean verdict [Unknown] — no source (null result)

Ambiguity note

The slug does not pin to a single prefix; 8 MA-L blocks across 3 exact name strings map to this registrant family. If a master row later specifies one prefix, verify against it before finalizing [Confirmed] — the IEEE MA-L registry

Analyst note

This is a B2B module maker; its OUIs appear on third-party finished goods (audio devices, trackers, IoT) that embed its Wi-Fi/BT/BLE modules, so the vendor's brand rarely shows on the end product.
