The below public listings should be searched prior
to applying for an OUI or IAB. Searching the list
will allow you to determine whether your company or
any parent/subsidiary companies already own an assignment.
When searching the public listings, addresses should
be entered as XX-XX-XX.
Your attention is called to the fact that the firms
and numbers listed may not always be obvious in product
implementations, as some manufacturers subcontract
component manufacture and others include registered
firm OUIs in their products.

OUI and company_id Assignments Announcement
These listings are updated daily.
The three-octet OUI can be used to generate Universal
LAN MAC addresses and Protocol Identifiers per ANSI/IEEE
Std 802 for use in Local and Metropolitan Area Network
applications.
If your firm manufactures or plans to manufacture
products using ISO/IEC 8802 standards, you should
apply to IEEE for your firm's OUI. The Institute of
Electrical and Electronics Engineers, Inc. has been
designated by the ISO Council to act as the registration
authority for the implementation of International
Standards in the ISO/IEC 8802 series. This is the
one world-wide source of registered OUIs. For further
