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.

Within a 64-bit section of the 1451.4 TEDS, called basic TEDS, the manufacturer of the transducer is defined with a 14-bit code called the manufacturer ID, along with manufacturer-assigned transducer model number, model letter, model version number and serial number.

Data acquisition systems may make use of the basic TEDS, including manufacturer ID, and model number data in determining the transducer type and the proper template to be used in unpacking TEDS data, particularly in the case of a transducer manufacturer choosing to use a non-IEEE, or manufacturer, template. Do not confuse manufacturer ID and basic TEDS with URN, as they are two separate and distinct entities. Every manufacturer of IEEE 1451.4 compliant transducers is required to use a unique IEEE 1451.4 manufacturer ID (see IEEE Std 1451.4-2004 subclause 5.1.1, Table 2).

The IEEE Registration Authority issues the manufacturer ID, to guarantee that it is unique to a manufacturer and publishes the list of existing IEEE 1451.4 manufacturer ID's.

Application Information
Please search the public listing to determine whether your organization has already been issued an assignment. If so, you may email us to obtain contact information for the assignment.

  1. Log in or create an account in order to apply for an assignment.
  2. A tracking number will be sent via email to the applicant. Any questions regarding your application will be sent via email to the primary email address provided at time of application.
  3. Applications are processed within seven (7) business days from receipt of payment. Be advised that the credit card will be charged once the application is submitted. Assignment details and a Paid Invoice will be available for download once the application is approved.
  4. Unless otherwise noted, applications are valid for 30 days.
  5. Since the public listing is updated once every 24 hours, new assignments will not be immediately viewable on the directory.

The IEEE Registration Authority will assign an additional manufacturer ID to any organization requesting one, providing they submit an affidavit on company letterhead to the IEEE Registration Authority c/o IEEE Standards Department, stating that their company will not "ship" product in the new manufacturer ID assignment until well after they have reached (shipped) at least 95% of the numbering capacity of the original manufacturer ID. The pool of individual transducer model numbers available to each holder of a single 14-bit manufacturer ID, using 50 bits of the 64-bit basic TEDS as defined in IEEE Standard 1451.4-2004, is in excess of 54.5 million models. Each model number may be produced up to a total in excess of 16.7 million serialized copies. The number of serialized copies of a model number may be increased by using additional version numbers, as defined by the Standard. A single manufacturer ID, within the structure of the IEEE 1451.4 Basic TEDS, may be used to identify in excess of 9 x 1014 individual transducers.
