Please search
our public
listing to determine whether your Organization
has already been issued an OUI or IAB assignment.
If your Organization has already been issued
an assignment, please email
us to obtain contact information for the
Administrator of the assignment. If a new assignment
is required, a Usage
Percentage Letter must be submitted.
Complete and
electronically submit the OUI application. Note: Do not submit more than one application unless you are requesting more than one assignment (see policy regarding obtaining an additional assignment).
A confirmation
email with a tracking number will be sent to
the REQUESTOR. If there are any questions regarding
your application, they will be sent via email
to the REQUESTOR. All emails are sent from ieee-registration-authority@ieee.org,
so please be sure that the REQUESTOR is able
to receive email from this address.
Applications
are processed within 7 business days from receipt
of payment. Be advised that all credit card applications will be charged once they are submitted. Assignment details and a Paid Invoice
are sent via email to the REQUESTOR.
The public OUI
listing is updated once every 24 hours, so new
assignments will not be immediately viewable
on the directory.
Please note that applications expire after 30 days.
The IEEE does not accept requests for applicant-specified
identifiers.
* As of 5 December 2003, companies
requesting confidentiality for Organizationally
Unique Identifiers (OUI) assignments will be required
to pay a fee for privacy. Assignees will also
be required to pay an annual fee to maintain confidentiality.
Payment options for the
renewal fee are credit card, check or wire
transfer.
This single assignment applies to all of these:
A)
The OUI defined in ANSI/IEEE Std 802-2001
can be used to generate 48-bit Universal LAN
MAC addresses to uniquely identify LAN and MAN
stations, and Protocol Identifiers to identify
public and private protocols. These are used
in Local and Metropolitan Area Network applications.
The relevant standards include:
CSMA/CD (IEEE 802.3, ISO 8802-3)
Token Bus (IEEE 802.4, ISO 8802-4)
Token Ring (IEEE 802.5, ISO/IEC 8802-5)
IEEE 802.6 (ISO/IEC DIS 8802-6) FDDI (ISO 9314-2)
WLAN (IEEE 802.11, ISO/IEC 8802-11)
B)
The 'company_id' relevant standards include:
defined in IEEE Std 1212-1991 Control and Status
Register (CSR) Architecture referenced by IEEE
Std 896.2-1991 Futurebus+Physical Layers and
Profiles
IEEE Std 1596-1992 Scalable Coherent Interface
IEEE Std 1394-1995 Serial Bus document. In this
context, the 24-bit company_id value is a portion
of the 32-bit Module_Vendor_Id ROM location
(and related locations) and uniquely identifies
hardware vendors and I/O software interface
architectures.
