Longcheer — ~4 prefixes (MA-L) across two entities; phone ODM, OUI ≠ brand on the box

Longcheer is a Chinese phone ODM, and its MAC footprint spans two IEEE registrants that should be aliased to one family: "LONGCHEER TELECOMMUNICATION LIMITED" (4 prefixes; MA-L; Shanghai) and "Longcheer Technology (Singapore) Pte Ltd" (1 prefix; Singapore). Verified samples under the Telecommunication Limited entity include B8:DE:5E and 8C:77:16. These OUIs appear on smartphones, tablets, and smart devices built for many brands, with a focus on budget and emerging-market handsets, so a Longcheer OUI may appear on a device sold under another brand — the same phone-ODM "OUI ≠ brand" pattern as Wingtech and Huaqin. For triage, a Longcheer OUI identifies the ODM and is common on budget or white-label handsets sold under many brands.

IEEE assignment

two entities — "LONGCHEER TELECOMMUNICATION LIMITED" (4; MA-L; B8:DE:5E, 8C:77:16, 0C:25:76, FC:3D:93; Shanghai), "Longcheer Technology (Singapore) Pte Ltd" (1; 00:23:B1; Singapore) [Confirmed] — IEEE MA-L

Registry / block size

MA-L; ~4 blocks under the Telecommunication Limited entity + 1 under the Singapore entity [Confirmed] — maclookup.app, hwaddress.com (IEEE-derived). NOTE: IEEE's public OUI data publishes NO assignment/registration date (the IEEE MA-L registry columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" from third-party tools is a database artifact, not an IEEE fact.

Unverified prefix

54:2F:04 (proposed → "Shanghai Longcheer Technology Co.") could NOT be confirmed against any IEEE-derived mirror and is NOT included — possible transcription error (note 54:32:04 = Espressif Inc.). No IEEE OUI registrant string "Shanghai Longcheer Technology Co." was found (the SSE-listed corporate entity 603341 is not an OUI assignee). [Unverified — omitted]

Special note

Phone-ODM "OUI ≠ brand" case (same pattern as Wingtech/Huaqin), with a budget/emerging-market focus. Two IEEE registrant strings only — "LONGCHEER TELECOMMUNICATION LIMITED" and "Longcheer Technology (Singapore) Pte Ltd". [Confirmed] — maclookup.app/vendors/longcheer-telecommunication-limited

none significant (ODM to many brands)

Analyst note

A Longcheer OUI identifies the ODM; common on budget/white-label handsets sold under many brands.
