The rapid rise of decentralized cryptocurrencies like Bitcoin has created a pressing need for standardized frameworks to ensure clarity, security, and interoperability across global financial systems. In response, the International Organization for Standardization (ISO) has introduced ISO 24165, a groundbreaking set of international standards designed to bring order and consistency to the identification of digital tokens.
This new standard establishes a universal system for generating and managing Digital Token Identifiers (DTIs)—unique, fixed-length codes that can be used to clearly identify any digital asset. As the crypto ecosystem expands beyond speculative trading into institutional finance, central bank digital currencies (CBDCs), and tokenized real-world assets, the importance of a globally recognized identifier system cannot be overstated.
Understanding ISO 24165: A Two-Part Framework
The ISO 24165 standard is structured in two parts, each addressing a critical aspect of digital token identification.
ISO 24165-1:2021 — Registration and Assignment Method
The first part, ISO 24165-1:2021 – Digital token identifier (DTI) – Registration, assignment and structure – Part 1: Method for registration and assignment, defines the technical process for allocating DTIs. It specifies how identifiers must be:
- Randomly generated to prevent predictability
- Globally unique to avoid duplication
- Fixed in length for system compatibility
- Publicly available to ensure transparency
These identifiers are assigned in response to formal registration requests that comply with defined application guidelines. This ensures that every digital token—whether it’s a cryptocurrency, stablecoin, utility token, or asset-backed token—can be accurately and unambiguously identified across platforms and jurisdictions.

ISO 24165-2:2021 — Data Elements for Registration
Complementing the first part, ISO 24165-2:2021 – Digital token identifier (DTI) – Registration, assignment and structure – Part 2: Data elements for registration outlines the specific data fields required in the registration process. These include:
- Token name and symbol
- Blockchain or distributed ledger technology (DLT) platform
- Issuer information
- Token type (e.g., fungible, non-fungible)
- Legal and regulatory classification
By standardizing these data elements, ISO 24165-2 ensures a one-to-one mapping between each digital token and its corresponding DTI. This eliminates confusion caused by multiple symbols representing the same asset—such as BTC and XBT both referring to Bitcoin—and supports reliable data exchange in financial reporting, compliance, and trading systems.
Why This Standard Matters Now
Dominique Tanner, chair of the working group that developed ISO 24165, emphasized the urgency behind this initiative:
"Without a universal standard for identifying tokens, and without a central authority managing them, the industry has ended up with many duplicate or conflicting identifiers. Users need a random, unique, unambiguous, publicly available, and fixed-length identifier. ISO 24165 meets exactly that need."
In practice, inconsistent token naming has already led to operational risks in exchanges, custodial services, and regulatory reporting. For example:
- A trading platform might list two different tickers for the same cryptocurrency due to regional naming differences.
- Regulatory filings could misidentify assets if symbols aren’t standardized.
- Cross-border transactions may face delays or errors when systems use incompatible identifiers.
With ISO 24165, financial institutions, regulators, exchanges, and blockchain developers gain a common reference framework—similar to how ISINs (International Securities Identification Numbers) work for traditional stocks and bonds.
Governance and Implementation
The registration authority for ISO 24165 is Etrading Software, a fintech company specializing in financial reference data. They are responsible for:
- Maintaining the official DTI registry
- Processing registration applications
- Publishing DTIs on a publicly accessible platform
This centralized registration function operates under the oversight of ISO/TC 68/SC 8, the subcommittee for Financial Services — Reference Data. The secretariat for this committee is hosted by SNV (Swiss Association for Standardization), the Swiss member body of ISO.
This governance model balances decentralization at the asset level with centralized control over identifiers—ensuring reliability without stifling innovation.

Frequently Asked Questions (FAQ)
What is a Digital Token Identifier (DTI)?
A DTI is a unique, fixed-length code assigned to a digital token under the ISO 24165 standard. It functions like a serial number for cryptocurrencies and other blockchain-based assets, enabling precise identification across systems.
How does ISO 24165 differ from existing ticker symbols like BTC?
Unlike informal tickers such as BTC or ETH—which can vary by exchange or region—DTIs are formally registered, globally unique, and generated using a standardized method. This reduces ambiguity and enhances interoperability.
Who can apply for a DTI?
Developers, issuers, or organizations launching new digital tokens can submit registration requests through the official DTI registration authority. Applications must include required metadata as defined in ISO 24165-2.
Is ISO 24165 mandatory?
No, compliance is voluntary. However, adoption is expected to grow among regulated financial institutions, exchanges, and central banks seeking alignment with international best practices.
Can NFTs be assigned DTIs?
Yes. While early focus has been on fungible tokens, the framework supports all types of digital tokens—including non-fungible tokens (NFTs)—as long as they meet registration criteria.
Will existing tokens like Bitcoin receive a DTI?
Eventually, major cryptocurrencies are likely to be registered under the system. For example, Bitcoin may be assigned an official DTI alongside its existing symbols (BTC/XBT), providing a standardized reference for institutional use.

The Road Ahead
As digital currencies evolve from niche innovations to mainstream financial instruments, standards like ISO 24165 will play a foundational role in building trust, reducing risk, and enabling seamless integration with traditional finance.
From decentralized finance (DeFi) protocols to central bank digital currencies (CBDCs), the need for clear, consistent identifiers will only increase. With its robust technical foundation and global legitimacy, ISO 24165 sets a new benchmark for how we identify and manage value in the digital age.
