MAC Address Vendor Lookup

Paste a MAC in any notation and get the IEEE-registered assignee, the block that covers it, and an honest answer when no vendor exists — on this device.

0 bytes uploaded

MAC address or OUI prefix

Colons, hyphens, dots, spaces or none at all; upper or lower case. 6, 7 or 9 hex digits is a registry prefix; 12 is an EUI-48 address and 16 is an EUI-64.

Enter a MAC address or an OUI prefix and its IEEE-registered assignee, the block that covers it, and the address bits appear here.

Showing 206 of 206 vendor blocks

This table lists 206 of the 53,618 blocks in the registry as retrieved — the lookup above reads all of them.

The three IEEE assignment sizes

The IEEE sells three sizes of address block, and which one a company bought decides how many hex digits have to match before the assignee is certain. These are the 53,618 assignments in the registry as retrieved on 2026-08-14.

Registry	Prefix length	Addresses in block	Assignments in this snapshot	What that means
MA-L	6 hex digits (24 bits)	16,777,216	39,939	The classic OUI: the first three octets are the assignee and the remaining 24 bits are the company's to allocate.
MA-M	7 hex digits (28 bits)	1,048,576	6,546	A quarter-million-address block. Seven digits identify the assignee, so a six-digit prefix alone can name several companies.
MA-S	9 hex digits (36 bits)	4,096	7,133	The smallest block, meant for low-volume products. Nine digits identify the assignee, and one 24-bit prefix can be split thousands of ways.

What the first octet says

Two bits of the first octet are flags rather than part of the assignee, and they are the reason an address can be perfectly valid and still have no vendor.

0x02 — the U/L bit: Set means the address is locally administered: something chose it rather than the IEEE assigning it. Phones and laptops set it when they randomize their address per network, which is why those addresses match no registry row at all.
0x01 — the I/G bit: Set means the address is a group (multicast) destination rather than one interface's own address. FF:FF:FF:FF:FF:FF, with every bit set, is the broadcast address.

IEEE Std 802-2014 §8.2 defines the transmission bit order that puts these two flags in the least significant bits of the first octet as it is written in hexadecimal — so 02:… and 06:… are locally administered, and 01:… and 33:33:… are group addresses.

Registered vendor blocks

The 206 blocks below are the assignees holding the most registrations, plus every prefix this page uses as an example. They are here so the page answers with no JavaScript and so each row has its own link; the lookup above reads all 53,618.

Reading a result honestly

The name is the registrant of the block, which is often the network-chip vendor rather than the brand printed on the case.
This is the registry as retrieved on a stated date, not a live query. A block registered since then is not here, and this page never asks the IEEE anything.
A locally administered or multicast address has no assignee by construction — that is an answer about the address, not a failure to find one.
A MAC address names a piece of hardware, so nothing you paste is uploaded, stored or turned into a shareable link.

How to use it

Paste the address. Colons, hyphens, Cisco dot-quads and bare digits read alike, and / jumps to the field.
Read the answer: assignee, registry, block size, and the first octet's two flag bits.
Copy any notation, paste a list for a batch, or search by company name.

Paste a MAC address in any notation and this page names the IEEE-registered assignee of the block it falls in, that block's size, and what the first octet says. The data is the IEEE MA-L, MA-M and MA-S registries as retrieved on 2026-08-14 — 53,618 assignments. Nothing you paste is uploaded.

Examples

00:1b:63:84:45:e6

Apple, Inc. · 00:1B:63 · MA-L · 16,777,216 addresses · universally administered · unicast

An MA-L assignment covers the whole 24-bit block, so the answer is who registered it.

70:B3:D5:00:12:34

SOREDI touch systems GmbH · 70:B3:D5:00:1 · MA-S · 4,096 addresses · universally administered · unicast

70:B3:D5 is subdivided: 4,093 assignments share it, so only the full address resolves.

02:1a:2b:3c:4d:5e

No vendor · 02:1A:2B · locally administered · unicast

The 0x02 bit is set: software chose this address, and no registry entry exists.

Every example on this page is executed against the same engine that powers the tool, on every build.

Gotchas worth knowing

A prefix names a registrant, not a manufacturer

Blocks belong to whoever registered them, often a chip vendor rather than a brand. Rebadged hardware keeps the buyer's name.

440 prefixes hold more than one company

Of 39,945 distinct 24-bit prefixes, 440 carry several blocks: 438 subdivided into MA-M or MA-S, two (08-00-30 and 00-01-C8) split between MA-L registrants.

Private is withheld, not missing

212 rows read Private: the registrant asked the IEEE not to publish a name. The block is assigned.

Common errors

“G” at position 5 isn't a hex digit or a separator — MAC addresses use 0–9 and A–F.: The read stops at the first character that is neither hex nor a separator.
14 hex digits doesn't match any MAC length — use 6, 7 or 9 for a prefix, 12 for an address, or 16 for an EUI-64.: Those five are the only lengths an address or IEEE assignment can have.

FAQ

Does the prefix tell me who made my device?

It names the company that registered the block, often the network-chip vendor rather than the brand on the case. Read it as a hint.

Why does my phone come back with no vendor?

Phones invent a fresh address per network with the locally-administered bit set, so nothing was ever registered. The page names the bit it read.

Is the address I paste sent to the IEEE?

No. The registry ships as 32 static chunks totalling 1.43 MB, a lookup fetches one, and the matching happens in this tab. Nothing is kept.

Keyboard shortcuts

/: Focus the address field

Nothing you paste here leaves this tab. State only ever travels in links you explicitly create.
