To register your entity for a LEI you will require a range of information including the entity’s registration authority number (e.g. for Australian entities this will generally be the ACN or ABN or ARSN), the entity’s legal name as it appears in the business register, the entity’s legal address and the entity’s headquarters address. Further, applicants will be asked to provide information about any parent relationship that exist, such as parent entity’s LEI and other reference data about the parent.
