LEI Registration for Investment Funds, ETFs and Sub-Funds

An LEI, or Legal Entity Identifier, is a uniquely assigned 20-character alphanumeric number that identifies companies, organisations, funds and trusts. The LEI number is the global standard for uniquely identifying legal entities, providing transparency, and supporting regulatory compliance. The LEI code is used to access verified data about the entity, such as its legal name and address, and information on its ownership structure.

LEIs can only be issued by approved LEI Issuers. These LEI Issuer organisations are accredited by the Global LEI Foundation (GLEIF), the regulatory body overseeing the Global Legal Entity Identifier System.

Registering an LEI for a fund follows a similar process as registering any legal entity, with a few fund-specific steps. You will need to provide the fund’s full legal name, its jurisdiction of formation, and its registered address. For funds that operate as sub-funds within an umbrella structure, you will also need to identify the umbrella fund and its LEI, as GLEIF requires relationship data to be reported where applicable. Similarly, the fund management entity — the manager, GP, or AIFM — should be identified as part of the registration.

Once submitted, RapidLEI’s verification checks the data against authoritative sources. In most cases the LEI is issued and published to the GLEIF database the same day. You can then use the LEI immediately in regulatory reporting, trading, and counterparty onboarding.

To register an LEI for a fund you will need the following information: the fund’s full legal name as registered with the relevant authority; the country and jurisdiction of formation; the registered address of the fund or its management entity; the entity type, for example whether it is a sub-fund, collective investment vehicle, or umbrella fund; the legal form under the applicable jurisdiction; the name and LEI (if available) of the fund management entity, general partner, or AIFM; and, for sub-funds, the LEI of the umbrella fund if one has already been issued. RapidLEI’s registration system will guide you through each field and flag where additional verification documentation may be required.

Not all funds require an LEI. A fund generally needs an LEI if it trades, reports derivatives, or is subject to regulatory reporting requirements that mandate its use.

Many investment funds are required to obtain a Legal Entity Identifier due to the regulations under which they trade or report, or because their regulated counterparties are required to identify them using an LEI.

In the EU and UK, MiFID II and MiFIR require regulated firms to identify legal entity clients using an LEI when executing and reporting transactions. If a fund does not have a valid LEI, trading activity may be restricted or blocked by brokers and trading venues.

Funds that are party to derivatives are also impacted by EMIR and UK EMIR. These regulations require LEIs to be used in derivatives trade reporting, meaning a missing or lapsed LEI can cause reporting failures and compliance issues.

In the United States, where the majority of global fund assets are issued, LEIs are widely used within regulatory reporting frameworks. CFTC swap reporting requires LEIs to identify counterparties to reportable derivatives, while SEC fund reporting increasingly relies on standardised identifiers within structured data submissions. As a result, fund managers and administrators frequently require funds to hold an LEI to meet regulatory and operational requirements.

The Global Legal Entity Identifier Foundation (GLEIF) was established in 2014 by the Financial Stability Board and the G20 and is overseen by the Regulatory Oversight Committee (ROC). The GLEIF is responsible for maintaining the operational integrity of the Global LEI System and works with accredited LEI Issuers to ensure that the LEI remains a public good accessible to all stakeholders.

The GLEIF also supports the broader adoption of the LEI across the global economy. Its work includes overseeing data quality, setting issuance standards, and promoting use cases such as cross-border trade and payee identification. This helps keep the LEI as the world’s most trusted and accessible way to identify organisations.
