All the regulations regarding legal entity identifier can be found here.
An LEI or legal entity identifier is a global 20-character alphanumeric code for identifying legal entities. Each LEI number is unique: it is assigned to each legal entity once and may not be assigned to any other entity. The Legal Entity Identifier is an exclusive identifier, as each legal person is only issued a single legal entity identifier.
The Legal Entity Identifier number does not replace the national registry code of a company.
The legal entity identifier connects a legal entity to its key reference information (name, location, etc.). The legal entity identifier number enables identifying legal entities participating in global financial markets for various supervisory purposes.
For example, legal entity identifiers are already being used under the European Market Infrastructure Regulation (EMIR) for identifying counterparties to over-the-counter derivatives transactions. On 1 November 2017, with the application of the Implementing Regulation (EU) No. 2017/105, using an LEI number was made mandatory for reporting all derivatives’ transactions.
Since 1 January 2017, all issuers have been required to have a Legal Entity Identifier for improving access to regulatory information.
Since 3 January 2018, legal entities are required to have an LEI number if they carry out transactions either in a trading venue (regulated market, multilateral trading facility, etc.) or outside a trading venue in connection with securities that are admitted to trading or traded on a trading venue or for which a request for admission to trading has been made, as well as securities where the underlying is a security traded on a trading venue or an index or basket composed of securities traded on a trading venue.
Investment service providers must request customers that are legal entities to provide all information that is necessary for submitting information about transactions to supervisory authorities. Such information includes legal entity identifiers.
If a customer who is a legal entity does not provide the investment service provider with the necessary information, including an LEI code, for reporting a security transaction, the service provider will not be able to fulfil their legal reporting obligation. Consequently, the investment service provider may refuse to provide the service.
LEI code applications may be submitted to authorised LEI operators. LEI codes are issued by LOUs (Local Operating Units). Assistance in applying for an LEI code may be received from official and non-official registration agents.
Banks and investment service providers verify the validity of legal entity identifiers from the GLEIF database. As GLEIF performs database updates once per day, the legal entity identifier issued to you will be listed in the database on the following day from 14.00 CEST. For example, if your LEI code was issued today, it will be listed in the global database tomorrow from 14.00 (CEST)

Legal Entity Identifier numbers are issued for a fee and an annual maintenance fee must be paid for the renewal of the code.
The price list for LEI registration is available here.
LEI Number normally issues your Legal Entity Identifier number within 24 hours from the moment of payment for the application (if the company submits any necessary additional documents promptly). We aim to issue LEIs in under 3 hours if you choose the fast-track option.
Renewing an LEI number is necessary to ensure that all information about the company connected to an LEI code is up to date. To ease the administrative burden on companies and organisations, LEI Number allows paying for multiple annual renewals. In this case, the LEI Number takes it upon itself to verify the information upon renewal of an LEI number for the designated period. Information updates are performed on the basis of official registry data.
