GSMA eUICC Identity Scheme

 

The GSMA is the industry appointed First Level EID Assignment Authority responsible for coordinating the issuance and use of the eUICC identification numbers. Each eSIM is identified by a unique 32 digit eUICC Identifier (EID).

The GSMA eUICC Identity Scheme provides each eUICC manufacturer with a unique 5 digit identity code to form the first part of the 32 digit EID.
