About the Registration Authority
IEEE offers Registration Authority programs or registries which maintain lists of unique identifiers under standards and issue unique identifiers to those wishing to register them. The IEEE Registration Authority assigns unambiguous names to objects in a way which makes the assignment available to interested parties.

Registries
MAC Address Block Large (MA-L)
An MA-L assignment includes an OUI and large blocks of EUI-48 and EUI-64 values which can be used as MAC Addresses, Bluetooth Device Addresses, Ethernet Addresses or object identifiers.
Learn More
MAC Address Block Medium (MA-M)
An MA-M assignment includes medium blocks of EUI-48 and EUI-64 values which can be used as MAC Addresses, Bluetooth Device Addresses, Ethernet Addresses or object identifiers.
Learn More
MAC Address Block Small (MA-S)
An MA-S assignment includes an OUI-36 and small blocks of EUI-48 and EUI-64 values which can be used as MAC Addresses, Bluetooth Device Addresses, Ethernet Addresses or object identifiers.
Learn More
Company ID (CID)
A unique 24-bit identifier that cannot be used to generate EUI-48 or EUI-64 values. Therefore, the CID is especially applicable in applications where unique MAC addresses are not required.
Learn More
EtherType™
Provides a context for interpretation of the data field of an Ethernet/IEEE 802.3 data frame (protocol identification).
Learn More
Manufacturer ID
The manufacturer of a transducer is defined with a 14-bit code called the manufacturer ID.
Learn More
Logical Link Control (LLC)
Contains addressing information that consists of the Destination Service Access Point (DSAP) and the Source Service Access Point (SSAP) address field.
Learn More
AcpcTreeId
An identifier for a specific set of binary trees used to convey certificate access codes to certificate users who are using the Activation Codes for Pseudonym Certificates (ACPC) technique specified in IEEE Std 1609.2.1. The assignee of an AcpcTreeId is assigned to operate an ACPC Certificate Access Manager using that AcpcTreeId.
Learn More
Unique Registration Number (URN)
A 64-bit unique identifier contained in memory devices, or nodes, in which IEEE 1451.4 TEDS data is stored.
Learn More
IEEE Template/TDL Item
IEEE template is a definition of the placement and significance of each piece of data stored within the TEDS memory. A TDL’s purpose is to map bits.
Learn More
Provider Service Identifier (PSID)
Used by IEEE 1609 standards to identify a particular application service provider that announces it is providing a service to potential users of an application or service.
Learn More
IEEE 802.16 Operator ID
A 24-bit number that is broadcast by a base station as part of its Base Station ID.
Learn More
Standard Group MAC Address
NOTE: For Standards Development use ONLY. A Universally Administered Address Block allocated for the assignment of Group MAC Addresses for use in Standards.
Learn More
IEEE 1667 Silo Type Identifier (STID)
IEEE 1667 specifies the interface to and behavior of several silos (e.g., Probe Silo, TCG Storage Transport Silo, Password Silo, and Smart Card Transport Silo). External silos may be defined outside of the standard, be either public or private, and involve third-party licensing. Guidelines for external silos are specified in IEEE 1667.
Learn More
IEEE Std 1588™ sdoId
The sdoId (Standards Development Organization Identifier) is a protocol attribute, per IEEE Std 1588, that identifies the PTP Profile in use by the PTP Instance.
Learn More
CtlSeriesId
An identifier for a Certificate Trust List series allowing for the management of roots of trust within the certificate management system as specified in IEEE Std 1609.2.1. The assignee of an CtlSeriesId serves as the SCMS Manager of that CtlSeriesId.

Registration Authority Governance and Additional Information
The IEEE Registration Authority operates under the direction of theIEEE SA Board of Governors.
Registration Authority Committee (RAC)
Oversight committee that assists standard developing organizations to establish unambiguous, sustainable registration authorities.
