Find the vendor name of a device by entering an OUI or a MAC address
What does it do?
MACLookup provides an easy way to search for MAC address prefixes and matches them to the chipset's manufacturer. It uses the IEEE database.
Vendors
We update the MAC address lookup database as soon as we have new information from the IEEE database and
Wireshark manufacturer database. There are more than 77K MAC address prefixes in the database.
The database was last updated on 6 November 2026
Data
For each search, you will always have the most accurate manufacturer, vendor or
organization data, without having to worry about updating a database.
You can freely download the database here
API
The public REST API is available for free and provides a powerful tool for retrieving detailed vendor information about any MAC address or OUI. With this API, you can seamlessly integrate MAC address and OUI lookup functionality into your applications, services, or systems. More info...
