According to CoinMeta, there are some common misconceptions regarding how to verify the authorization of CASP (cryptocurrency service providers) during registration with the European Securities and Markets Authority (ESMA). The registration information may not match what is displayed in applications or messages, and the brand names may differ from those of the legal entities. It is recommended to use the Legal Entity Identifier (LEI) LEI for verification, as it is associated with the legal entity. Some regulatory authorities do not provide separate license numbers, and the regulatory approaches vary from country to country. If a company is not found in the registration, it may be that the application is still under consideration, or the company serves EU customers through authorized partners. The registration records for ESMA are updated weekly, and confirming the authorization of a legal entity does not guarantee that the messages received are genuine.
