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.

a Values are listed in ISO 15628 as dsrcApplicationEntityId (AID).

b A PSID value allocated to the IEEE 1609 working group (WG) for testing purposes is not identified with a standard application area. It is expected to be used only in testing environments, not to convey information about deployed applications. The meaning associated with a given testing PSID value will be specific to the testing environment in which it is used. The means by which a WAVE device determines the meaning of a testing PSID value are outside the scope of this standard.

c A reserved PSID value is not available for allocation in the current version of the standard. The IEEE 1609 WG may allocate the reserved values in a future version.

d A PSID value allocated to the IEEE 1609 WG for unregistered use is not identified with a standard application area. A set of WAVE devices can use an unregistered value to convey a mutually agreed meaning. Both the meaning and the means by which the devices determine the meaning are outside the scope of this standard. There is no assurance that all devices operating in a given area attach the same meaning to the value.
