Legal Entity Identifier (LEI): The future of digital company identification

4 June 2025

Efficient, transparent and globally recognised: The LEI is becoming mandatory for modern companies.

The digital transformation does not stop at company identification. The Legal Entity Identifier (LEI) has established itself as an internationally valid, standardised code that can be used to identify companies uniquely. Whether for capital market transactions, regulatory reporting, or digital customer verification, the LEI number is becoming increasingly relevant.

What is an LEI?

The LEI is a 20-digit alphanumeric code based on the international standard ISO 17442. It is managed by the Global Legal Entity Identifier Foundation (GLEIF) and issued via so-called Local Operating Units (LOUs). Every company that operates on the financial market or is subject to regulatory reporting obligations requires a valid LEI number.

Why is the LEI number so significant?

– It ensures the unique identification of legal entities

– It facilitates the traceability of transactions

– It fulfils essential requirements in the area of anti-money laundering (AML) and Know Your Customer (KYC)

– It improves data quality in the global financial system

LEI number registration: simple, digital and reliable

LEI number registration is a straightforward process that is now carried out online via certified registration centres. Companies provide basic information, such as the company name, legal form, registered office, and parent-subsidiary relationships. The registrar conducts validation in collaboration with public data sources, including commercial registers.

Advantages of digital LEI registration

– Fast issuance within 24 hours

– Simple renewal of existing LEIs

– High data quality thanks to automated verification steps

– Transparent presentation in the GLEIF database

The vLEI – the next level of digital identity

The verified LEI (vLEI) represents the next innovation: a digital proof of identity that builds upon the existing LEI and can be seamlessly integrated into electronic signatures and blockchain applications. The vLEI enables companies to demonstrate their trustworthiness in digital ecosystems – without relying on paper documents.

Advantages of the vLEI at a glance:

– Tamper-proof digital identity

– Automated processes for concluding contracts

– Strong integration into digital platforms and smart contracts

LEI has a competitive advantage in the digital age

For companies, banks and financial service providers, a valid LEI means more than just fulfilling regulatory obligations. It is a clear signal of transparency, reliability and willingness to innovate. In particular, LEI number registration via validation agents (e.g. banks during onboarding) results in considerable efficiency gains.

Conclusion: Apply for an LEI now and set yourself up for the future

The importance of the Legal Entity Identifier is continually growing, even outside the financial market. Whether for regulatory purposes, digitalisation or building trust in the B2B sector, the LEI number is the key to standardised, secure company identification.
