EID (Embedded Identity Document)
An EID is a unique 32-digit serial number physically embedded into the phone's secure eUICC chip, which acts as a digital vault for storing eSIM profiles. Unlike a 15-digit IMEI that identifies the modem to the network, the EID identifies the specific secure element chip capable of holding multiple virtual SIM cards.
Whenever you request a new line of service from a telecommunications provider, their servers encrypt the digital subscriber profile and route it specifically to your hardware's 32-digit embedded identity. Buyers should never share their EID publicly on marketplaces, as malicious actors could use these secure identifiers to attempt unauthorized network transfers.
