ANNA becomes member of Global Blockchain Business Council (GBBC) As ANNA continues to issue XT ISINs for crypto assets.

London, 20 th November 2023: The Association of National Numbering Agencies (ANNA), a global
member association seeking to foster standardisation within the financial industry and ISO
Registration Authority for ISO 6166 International Securities Identification Numbers (ISINs),
announces its new membership of Global Blockchain Business Council (GBBC). This comes in the
same year that ANNA is issuing new XT ISINs to identify crypto assets to further optimise and
automate more comprehensive data sets within the ISO standard registry.

Stephan Dreyer, MD of ANNA, said: “We are very happy that ANNA is now a new observing member
of GBBC, the largest leading industry association for the blockchain technology and digital assets
community. Digital assets are a key strategic topic for ANNA, and we continue to work together with
associations and organisations that share the same core values and ambition as us, to make the
digital asset space more transparent for the benefit of the market.”

ANNA recently also announced that its work on a joint Task Force with the Digital Token Identifier
Foundation (DTIF) resulted in a joint Memorandum of Understanding (MOU) between the two
organisations. ANNA’s National Numbering Agencies (NNAs) have been issuing ISINs for financial and
referential instruments for over thirty years, including ISINs for a number of security tokens. ANNA’s
new XT ISINs under the MOU are complementary and interoperable with the DTIF’s Digital Token
Identifier (DTI). Both have different functions but are intrinsically linked. Where the ISIN identifies
the asset, which has historically always been the case and will continue to be, the DTI uniquely
identifies the implementation of the token on a DLT. Under the MOU, those DTIs included in the DTI
register can be issued an ISIN at ANNA’s discretion. This integration will reduce operational
complexity and industry costs and provide a clear link between an asset and a digital token(s) that
relates to the asset.
