MAC Vendor Lookup
Look up device manufacturer from a MAC address OUI prefix against a built-in list of ~550 vendors, from Apple and Samsung to Intel and Cisco. Code never leaves your device — formatting and validation run locally in your browser.

Frequently Asked Questions
What is a MAC address OUI?
The OUI (Organizationally Unique Identifier) is the first 3 octets (6 hex characters) of a MAC address. It uniquely identifies the device manufacturer or vendor, assigned by IEEE.
What information does the lookup return?
The vendor/manufacturer name associated with the MAC address OUI prefix. For example, looking up 00:1A:2B returns the manufacturer who owns that OUI block.
Can I identify the device model?
The OUI identifies the manufacturer but not the specific model. To identify the exact device, you need additional information like network scanning or device fingerprinting.
How comprehensive is the vendor database?
A built-in static list of about 550 OUI entries covering major manufacturers (Apple, Samsung, Cisco, Intel, etc.) and smaller vendors. It ships with the tool and is not updated live — unknown prefixes report 'Unknown vendor'.
Is the lookup done locally?
Yes. The OUI database is stored locally. No MAC address data is transmitted during lookups.
