Samsung Electronics holds roughly 885 MA-L blocks — about 14.8 billion addresses — under the primary registrant "Samsung Electronics Co.,Ltd" (note the missing space after the comma). Two smaller registrant strings, "SAMSUNG ELECTRONICS" (~2 blocks) and "Samsung Electronics.,LTD" (~2 blocks), also exist and should be normalized to Samsung in the pipeline. The corporate base is Suwon, South Korea, though individual blocks list facility addresses such as Gumi, Gyeongbuk. These OUIs appear across Samsung's enormous device range: Galaxy phones and tablets, smart TVs, Family Hub appliances, monitors, wearables, and NVMe SSDs. The key analyst caveat is MAC randomization: modern Galaxy handsets run Android 10+, so on Wi-Fi they typically present a locally-administered random MAC rather than their burned-in Samsung OUI — meaning the absence of a Samsung OUI on a wireless segment does not mean the absence of Samsung devices. The burned-in Samsung MAC still exists on the chipset and shows up on wired or non-randomized interfaces. For triage, a Samsung OUI usually marks a phone, TV, or appliance, with the randomization caveat front of mind for any MAC-based device inventory.
- IEEE assignment
- ~885 prefixes → Samsung Electronics Co.,Ltd, South Korea; plus smaller registrants "SAMSUNG ELECTRONICS" (~2) and "Samsung Electronics.,LTD" (~2) [Confirmed] — IEEE MA-L
- Registry / block size
- MA-L; ~885 blocks (~14.8B addresses) [Confirmed assignment] — maclookup.app (IEEE-derived; count is a current third-party snapshot and drifts). NOTE: IEEE's public OUI data publishes NO assignment/registration date (oui.csv columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" from third-party tools is a database artifact, not an IEEE fact.

- Special note
- Modern Galaxy devices use MAC randomization (Android 10+), so a phone may present a locally-administered random MAC on Wi-Fi rather than its Samsung OUI; the burned-in Samsung MAC remains on the chipset. Multiple Samsung registrant strings exist — normalize them. [Confirmed] — maclookup.app
- Related vendors
- Samsung Electro-Mechanics and other Samsung group entities may hold separate registrations
- Analyst note
- A Samsung OUI usually marks a phone, TV, or appliance; on enterprise Wi-Fi expect randomized MACs from Galaxy handsets, so absence of a Samsung OUI does not mean absence of Samsung devices.
