MAC Address Lookup (Vendor & OUI Finder)
Free MAC address lookup tool that identifies the vendor behind any device from the first 6 digits (OUI) of its MAC address. Supports major manufacturers like Apple, Samsung, and Cisco, and detects locally administered and multicast addresses. Everything runs in your browser, so nothing is ever sent to a server.

What Is a MAC Address Vendor Lookup?
A MAC address vendor lookup lets you enter a network device's MAC address (or just its first 6 digits, the OUI) and instantly find out which manufacturer that address was assigned to. This tool checks your input against a browser-side database built from the OUI (Organizationally Unique Identifier) records the IEEE publishes, covering major vendors like Apple, Samsung, Cisco, and Google, and returns a result immediately without any data ever leaving your device.
It also automatically determines whether the address you entered is a randomly generated "locally administered address" or a genuine "globally unique address" tied to a real manufacturer. Because modern smartphones increasingly use randomized MAC addresses for privacy when connecting to Wi-Fi, it is now common for a lookup to come back with no vendor match. This tool explains that reason alongside the result, so you understand not just that a match was not found, but why.
How to Use This Tool
- Enter a MAC address Paste in a MAC address from your device's network settings, with or without separators — either format works.
- Or search with just the OUI If you only know the first 3 bytes (6 digits), that is enough on its own to get the same vendor result.
- Check the result badges Along with the vendor name, you will see a badge indicating whether the address is a multicast address or a locally administered one.
- Browse the vendor table The table below can be filtered by vendor name or OUI, so you can also use it in reverse to look up OUIs for a specific manufacturer.
Tips for getting more out of it
- You can paste a MAC address exactly as it appears, separators and all (colons, hyphens, or dots) — the tool strips them out automatically before matching.
- You only need the first 6 digits (the 3-byte OUI) to get a result. The remaining 6 digits, which uniquely identify the individual device, are not used for vendor matching.
- If the MAC address your phone uses for Wi-Fi starts with "02", "06", "0A", or "0E", it is almost certainly a randomly generated address created for privacy, and the real vendor cannot be determined from it.
- This tool only covers a curated set of OUIs from major manufacturers. If your address is not found here, check the official OUI registry published by the IEEE.
- It is common for a single manufacturer to hold several different OUI blocks. If one OUI does not turn up a match, the same company may simply be using a different block.
Use Cases
Identifying unfamiliar devices
If an unrecognized MAC address shows up in your home router's list of connected devices, the vendor name is a useful clue to what kind of device it might be, such as a smart appliance or a printer.
Network hardware inventory
Determine the manufacturer behind devices connected to a corporate network from their MAC addresses, and use that information to keep an asset register up to date.
Verifying MAC address filtering rules
Before adding a device to a Wi-Fi router's access control list, confirm that its vendor is correctly recognized.
Building test and development data
When emulating network hardware or generating test data, use real vendor OUIs as a reference to make the data more realistic.
Glossary
- OUI
- Short for Organizationally Unique Identifier. The first 24 bits (3 bytes) of a MAC address, assigned by the IEEE to identify a specific manufacturer.
- MAC address
- Short for Media Access Control address. A 48-bit identifier assigned to a network device's NIC (network interface card) that is unique to that piece of hardware.
- Locally administered address
- A MAC address generated by software rather than assigned from an IEEE-issued global OUI block. This applies whenever the second-to-least-significant bit (the U/L bit) of the first byte is set to 1.
- Multicast address
- An address meant to deliver data to a group of devices at once rather than a single device. This applies whenever the least significant bit (the I/G bit) of the first byte is set to 1.
- NIC
- Short for Network Interface Card. The hardware component that connects a computer to a network and is assigned a unique MAC address at the factory.
Frequently Asked Questions
Side Note — The Manufacturing History Hidden in the First 6 Digits of a MAC Address
The 48-bit identifier we call a MAC address traces back to the invention of Ethernet at Xerox's Palo Alto Research Center (PARC) in the 1970s. In the earliest days, each company simply assigned its own addresses, but once devices from different manufacturers started talking to each other across the world, a system was needed to guarantee no two devices ever shared the same address. The IEEE stepped in to manage this, reserving the first 24 bits (3 bytes) as an "OUI" (Organizationally Unique Identifier) that it hands out to manufacturers on a one-per-company basis. Today, as the number of companies needing an assignment has grown, the IEEE also offers smaller registration blocks (MA-M and MA-S) for organizations that do not need a full OUI.
The first byte of every MAC address quietly encodes two technically important bits. If the least significant bit (the I/G bit) is set to 1, the address is a "multicast address" meant to reach a group of devices at once rather than a single machine. If the second-to-least-significant bit (the U/L bit) is set to 1, the address is "locally administered" — generated by software rather than assigned by the IEEE as part of a global OUI block. Both conventions have remained unchanged since the earliest days of Ethernet.
Starting with iOS 8 in 2014, smartphones began adopting a privacy feature known as "MAC address randomization," which substitutes a randomly generated address for the device's real one whenever it scans for Wi-Fi access points. This has made it much harder for retailers and public venues to track visitors by MAC address, but it has also made MAC-based device identification and access control lists considerably less reliable for network administrators. If you look up a MAC address here and get an unknown vendor, there is a good chance randomization is the reason.
