MA-L PUBLIC LISTING
If your firm manufactures or plans to manufacture products using ISO/IEC 8802 standards, you should apply to IEEE for your firm's MA-L. IEEE 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 MA-Ls. For further details contact:

IEEE MA-L Assignments
The below public listing should be searched prior to applying for an MA-L. Searching the list will allow you to determine whether your company or any parent/subsidiary companies already own an assignment. When searching the public listing, addresses should be entered as XX-XX-XX.
Firms and numbers listed may not always be obvious in product implementations, as some manufacturers subcontract component manufacture and others include registered firm MA-Ls in their products.
The three-octet MA-L 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.
Please be advised that the MA-L/OUI listing is updated on a daily basis. If you are making queries from this public listing, it is recommended that you download it once per day and parse it locally.
