Identify Devices by MAC
The first 3 bytes (6 hex chars) of a MAC address are the OUI — Organizationally Unique Identifier, assigned by IEEE. Look up any MAC and discover its manufacturer: Apple, Samsung, Cisco, TP-Link, Intel, and more.
Accepted Formats
AA:BB:CC:DD:EE:FF, AA-BB-CC-DD-EE-FF, AABB.CCDD.EEFF, AABBCCDDEEFF. Case-insensitive. The tool normalizes input and extracts the OUI for lookup.
MAC Types
Unicast (first byte even) vs multicast (first byte odd). Universally administered (U/L bit = 0) vs locally administered (U/L bit = 1 — includes randomized MACs used by modern phones for privacy).
FAQ
Why does my phone show a random vendor?
iOS and Android randomize Wi-Fi MAC per network for privacy. The OUI is synthetic.

Why Use This MAC Address Lookup?
The MAC Address Lookup runs entirely in your browser, which means three things matter for you. First, it's instant — there's no server round-trip, no upload, no waiting on someone else's queue. Second, it's private — nothing you enter ever leaves your device, which makes it safe for sensitive numbers, draft copy, or files you don't want sitting on a third party's servers. Third, it's free forever — no signup, no email capture, no "basic vs. pro" upsell. Open the page, get the answer, close the tab.
Common Use Cases
- Everyday lookups when you need a fast, reliable answer without installing an app
- Cross-checking results from another tool or spreadsheet when accuracy matters
- Quick reference during work calls, school assignments, or planning sessions
- Sharing the link with a colleague or friend who needs the same answer
- Bookmarking for repeat tasks that come up regularly throughout the week
Privacy & How Your Data Is Handled
Every calculation and every transformation in the MAC Address Lookup runs locally in your browser using standard JavaScript. We don't upload your input to any server, we don't log it, and we don't pass it to a third-party API. The tool works the same whether you're on a fast home connection or completely offline once the page has loaded. If you want to verify this for yourself, open your browser's network tab and run the tool — you won't see any outbound request carrying your data.
