OUI Lookup and Database

Find a device's manufacturer by its MAC address and browse OUIs assignments
New in version 1.6.7
* Made the data update process more reliable
* Fixed an issue with data updates on devices using non-English languages
* Updated the built-in manufacturer database (October 4, 2026)
* Improved compatibility with Android 17
With OUI Lookup you can figure out who manufactured a device simply by inserting its MAC address in the search bar.
You can also search for a manufacturer and see its assigned OUIs.

Features:
  • Trusted source - The database is sourced from the IEEE to be as correct and updated as possible.
  • Works Offline - OUI Lookup works completely offline, an internet connection is only needed to update the database.
  • Bulk lookup - You can paste a comma/semicolon/whitespace/new line separated list of MAC Addresses to perform a multiple lookup.
  • Auto-paste from the clipboard when there is one or more MAC addresses
  • Dark theme is supported

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
