The National Association of Digital Broadcasters
(NAdB) was founded in 2009 to provide support, education and advocacy functions for
Internet radio and streaming digital broadcasters in the
United States, including assignment and administration
of call letters for digital/streaming radio stations.
In addition to its mission as the leading advocate for digital
broadcasters, the NAdB serves as the liaison to IRUC/DRuID Radio in order to provide a uniform system of
assigning callsigns (call letters) to Internet-only
radio stations in the United States.
traditional over-the-air broadcast stations are
typically assigned call letters by their national
authority (such as the Federal Communications Commission
in the United States), no such system existed for the
tens of thousands of Internet-only stations.
Digital Radio Uniform Identifiers (DRuIDs) are assigned by a
nonpartisan international administrative team upon the
request of station owners. DRuID prefixes are
pre-assigned to individual countries and regions under
standards established by the International
Telecommunication Union (ITU) and adapted for the
diverse Internet/Digital Radio community.
