Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that

Introduction
The industry has considered issues with current digital identity tools and solutions and has devised a new
approach to digital identity management. Thanks to advances in distributed ledger/blockchain technology,
digital identity management with the additional feature of decentralized identity verification is now
possible. Based on a concept known as “self-sovereign identity (SSI)”, this new approach for authentication
and verification of digital identity began as a means by which a person, the identity holder, has control of
their personal data over how, when and to whom those data are revealed. This approach is set to transform
the nature of identity management and how person-to-entity, or entity-to-entity, interactions take place in
the digital world. It can address the need for automation in verification while maintaining data privacy and
confidentiality.
The legal entity identifier (LEI) plays a key role in this process. So, the Global Legal Entity Identifier
Foundation (GLEIF), manager of the Global LEI System in which the ISO 17442 series has been implemented,
continues its work so that each business worldwide has only one global identity and this includes a digital
identity by expanding the ISO 17442 series. This document is dedicated to leveraging the LEI in digitally
signed credentials that are not only tamper-resistant but capable of being verified in a decentralized manner.
Chaining of the verifiable legal entity identifier (vLEI) credentials in the vLEI trust chain using authentic
chained data container (ACDC) credentials allows for the provenance of vLEIs to be traced back to GLEIF
as both the root of trust for the vLEI trust chain as well as to the entity, under regulatory oversight, that
ensures the operational integrity of the global LEI system.
This document enables LEIs to be used in both the recent innovation of credentials based on decentralized
digital identity as well as X.509 public key certificates as outlined in ISO 17442-2.
As with standard X.509 digital certificates, vLEIs will use ISO 5009. Combining LEIs with official
organizational roles is a key enabler for digital identity management for organizations and persons acting
on behalf of organizations.
