Legal Entity Identifier (LEI)

Note - from version 2.0.0:

• New Java package name
• New group ID in Maven / Gradle dependency declaration
• Moved repository from JCenter to Maven Central Repository

The Legal Entity Identifier (LEI) is unique global identifier of legal entities participating in financial transactions. These can be individuals, companies or government entities that participate in financial transaction. The identifier is used in reporting to financial regulators and all financial companies and funds are required to have an LEI.

The identifier is formatted as a 20-character, alpha-numeric code based on the ISO 17442 standard developed by the International Organization for Standardization (ISO). It connects to key reference information that enables clear and unique identification of legal entities participating in financial transactions. Each LEI contains information about an entity’s ownership structure and thus answers the questions of 'who is who’ and ‘who owns whom’. Simply put, the publicly available LEI data pool can be regarded as a global directory of participants in the financial market.

This Java library makes it easy to lookup LEI information.

Lookup examples

Search LEI by legal name

LeiLookup lookup = LeiLookup.getInstance();
List<Lei> lei = lookup.getLeiByLegalName("Apple");

Search LEI by LEI code

LeiLookup lookup = LeiLookup.getInstance();
Optional<Lei> lei = lookup.getLeiByLeiCode("W22LROWP2IHZNBB6K528");

Search LEI by ISIN code

LeiLookup lookup = LeiLookup.getInstance();
Optional<Lei> lei = lookup.getLeiByIsinCode("US0378331005");

Search LEI by BIC code

LeiLookup lookup = LeiLookup.getInstance();
Optional<Lei> lei = lookup.getLeiByBicCode("BUKBGB22XXX");

Search LEI by CUSIP

LeiLookup lookup = LeiLookup.getInstance();
Optional<Lei> lei = lookup.getLeiByCusip("931142103");

Search LEI by SEDOL

LeiLookup lookup = LeiLookup.getInstance();
Optional<Lei> lei = lookup.getLeiBySedol("0884709");

Validation examples

Check if LEI code format is valid

boolean valid = LeiCodeValidator.isValid("W22LROWP2IHZNBB6K528");

Check if ISIN code format is valid

boolean valid = IsinCodeValidator.isValid("US0378331005");

Check if BIC code format is valid

boolean valid = BicCodeValidator.isValid("DEUTDEFFXXX");

Check if CUSIP format is valid

boolean valid = CusipValidator.isValid("931142103");

Check if SEDOL format is valid

boolean valid = SedolValidator.isValid("0884709");
