Universal Electronics, Inc. — 29 prefixes (MA-L)

Universal Electronics, Inc. (UEI) holds a substantial OUI footprint — 29 distinct IEEE MA-L blocks registered to the exact string "Universal Electronics, Inc.", nearly all at 201 E. Sandpointe Ave, Santa Ana, CA 92707, US. UEI is a publicly traded company (Nasdaq: UEIC), founded in 1986, and one of the largest makers of home-entertainment remote controls in the world, with an estimated ~30% global share. Its hardware and platforms span the One For All line of universal remotes, OEM voice/set-top-box remotes for pay-TV operators (e.g. Astro), Ecolink DIY and professional home-security sensors (motion, door/window), smart thermostats and hubs, and the QuickSet Cloud SDK/web-service family used for device discovery and universal control across smart-home and connected-TV ecosystems. Two disambiguations matter. First, this is NOT "Universal Electric Corporation" (Canonsburg, PA — the Starline busway maker), which holds its own separate prefixes D8:24:77 and 58:2F:42 and is tracked as a distinct DONE entry. Second, "Baltic Latvian Universal Electronics LLC" (prefix FC:55:DC) is an unrelated company by a different name and must not be folded in. A closely related registry string, "Universal Electronics BV" (Enschede, Netherlands, prefix 20:21:41), plausibly represents UEI's European R&D office but is a textually distinct entry and is footnoted rather than silently merged — this likely accounts for the "30 IEEE OUI assignments" the already-rendered site page cites versus the 29 exact-string rows counted directly in the cached registry. IEEE publishes no assignment date for MA-L blocks, so none is recorded here.

IEEE assignment

29 prefixes → Universal Electronics, Inc., registered Santa Ana, CA, US [Confirmed] — IEEE MA-L (29 exact-string rows)

Registry / block size

MA-L (24-bit OUI, /24 block); 29 prefixes. Verified only in the IEEE MA-L registry — no matching entries for this org in the IEEE MA-M registry (MA-M) or the IEEE MA-S registry (MA-S). [Confirmed] — IEEE MA-L (the IEEE MA-M registry, the IEEE MA-S registry). NOTE: IEEE public OUI data publishes NO assignment/registration date; any "date registered" on third-party tools is a database artifact, not an IEEE fact.

HQ / country

201 E. Sandpointe Ave, Santa Ana, CA 92707, US (registry address; a few blocks list the fuller ZIP 92707-5778, one omits the state abbreviation, one older block 001CFD carries a prior Cypress, CA address — otherwise consistent across all 29) [Confirmed] — IEEE MA-L

Security context

No CVE or public vulnerability disclosure was found naming Universal Electronics, UEI, QuickSet, or Ecolink in this pass (absence of findings, not proof of none — a general web/CVE pass, not an exhaustive audit). UEI's own materials describe engaging a third party (SecuriThings) to detect/mitigate threats such as rogue-device connections and data-scraping against the QuickSet Cloud IoT platform, and describe newer QuickSet Widget Pro hardware as supporting secure boot, encrypted communication, and hardware security modules — these are vendor marketing claims about posture, not independently verified findings or incident reports.

Disambiguation

NOT "Universal Electric Corporation" (Canonsburg, PA — Starline busway, prefixes D8:24:77, 58:2F:42; separate DONE entry). NOT "Baltic Latvian Universal Electronics LLC" (prefix FC:55:DC, a different company). "Universal Electronics BV" (Enschede, NL, prefix 20:21:41) is a textually distinct registry string, plausibly UEI's European office, footnoted rather than merged.

[Confirmed] — IEEE MA-L, /mac/vendor/universal-electric/

Prefix-count note

The already-rendered site page cites "30 IEEE OUI assignments"; this pass found 29 exact-string "Universal Electronics, Inc." rows in the cached the IEEE MA-L registry. The 30th is most plausibly the separately named "Universal Electronics BV" (Enschede, NL) row being included. Flagged for reconciliation, not silently resolved.

[Likely] — the IEEE MA-L registry, mac/vendor/universal-electronics/index.html

IANA Reference

not applicable — OUI/MAC vendor entries have no IANA Reference column [Confirmed] — IEEE MA-L

Analyst note

Registry facts (29 MA-L prefixes, org string, Santa Ana address) are Confirmed from the IEEE MA-L registry. Company/product identity is independently corroborated by Wikipedia + uei.com + a BusinessWire press release, so it is also Confirmed here (unlike the inferred-identity sibling entry). No CVE found for this vendor in this pass.
