The slug "vendor-along-communication" resolves to two distinct IEEE MA-L OUI assignments that belong to the same Shenzhen, China electronics maker under slightly different filed names: BC:49:B2, registered to "SHENZHEN ALONG COMMUNICATION TECH CO., LTD," and 3C:91:74, registered to "ALONG COMMUNICATION TECHNOLOGY." Both registrations list the same address — Room 1301, Zhenye International Business Center, Qianhai Road, Nanshan District, Shenzhen, Guangdong 518000 — which is the strongest single signal that they are one corporate entity (the company's own web presence at along.cc uses the related legal name "Shenzhen Along Electronics Co., Ltd."). The company is an Android ODM/OEM: its main output is consumer Android smartphones and tablets built for third-party brands, with Google GMS certification and SoCs from MediaTek, Allwinner, and Rockchip; secondary lines documented include set-top boxes, VR/AR headsets, and embedded MID boards. Practically, a BC:49:B2 or 3C:91:74 MAC on a network is most consistent with a consumer Android phone or tablet, not network infrastructure. No CVEs or public threat-intelligence reports name this vendor as of June 2026 — a low public profile, not a verified clean bill of health. The "dates" shown in third-party MAC-lookup tools are database-ingestion artifacts, not IEEE-published registration dates; IEEE publishes no per-OUI assignment date.
- IEEE assignment 1
- BC:49:B2 → SHENZHEN ALONG COMMUNICATION TECH CO., LTD, Shenzhen, CN [Confirmed] — IEEE MA-L (oui.csv line 275)
- IEEE assignment 2
- 3C:91:74 → ALONG COMMUNICATION TECHNOLOGY, Shenzhen, CN [Confirmed] — IEEE MA-L (oui.csv line 11805); corroborated by third-party mirrors (aruljohn.com, cleancss.com)
- Registry / block size
- both MA-L (24-bit OUI; ~16.8M addresses each) [Confirmed] — IEEE MA-L
- HQ / country
- Room 1301, Zhenye International Business Center, Qianhai Road, Nanshan District, Shenzhen, Guangdong 518000, China (CN); both registrations share this address [Confirmed] — IEEE MA-L / aruljohn.com
- Company / brand
- operates under the "Along" brand; web presence along.cc attributed to "Shenzhen Along Electronics Co., Ltd." — a related legal name on the same company's site [Likely] — along.cc/gms.aspx
- Parent/entity relationship
- BC:49:B2 and 3C:91:74 share an identical registered address, strongly indicating the same legal entity (or closely related entities) under the "Along" brand; "Along Communication Technology" appears to be the earlier/abbreviated filing, "Shenzhen Along Communication Tech Co., Ltd." the later formal name [Likely] — cleancss.com, aruljohn.com, along.cc
- Device types
- Android smartphones and tablets (primary); set-top boxes, VR/AR headsets, embedded/MID boards (secondary); Google ODM partner using MediaTek/Allwinner/Rockchip SoCs [Likely] — along.cc/gms.aspx, camerafv5.com, made-in-china.com
- Company status
- active (self-reported founding early 2003 per along.cc About page, indexed but not directly fetchable) [Likely] — along.cc/about.aspx
- Registration date
- null — IEEE publishes NO per-OUI registration/assignment date. Third-party first-seen dates (maclookup.app: 2012-04-08 for 3C:91:74, 2022-12-13 for BC:49:B2) are database-ingestion artifacts, not IEEE facts; do not attribute them to IEEE. [Confirmed] — maclookup.app (artifact dates)
- IANA reference
- not applicable — IANA references cover port/protocol assignments, not IEEE OUI/MAC registrations; left blank [Confirmed] — (no applicable IANA assignment type)
- Security context
- no CVEs or public security advisories name Along Communication Technology / Shenzhen Along Communication Tech Co., Ltd. as of June 2026; as a low-to-mid-tier Android ODM the general risk class (delayed/absent patches, pre-installed apps of uncertain provenance) applies, but nothing ties this vendor to malicious firmware or state-sponsored activity. Absence of findings reflects low public profile, not verified safety. [Likely] — nvd.nist.gov, cvedetails.com (no matches)
- Analyst note
- a device showing BC:49:B2 or 3C:91:74 is most likely a consumer Android phone or tablet, not router/network infrastructure; treat the OUI as a device-class hint, not a firmware-trust signal.
