The EID is the serial number of the eSIM chip inside your phone — a 32-digit number that identifies the chip itself, not you and not your plan
Every embedded SIM chip leaves the factory with one. Networks use it to deliver a profile to the right device, and support teams occasionally ask for it when an installation will not complete. It is the eSIM equivalent of the number printed on a plastic SIM card.
Where to Find It
- Any phone: dial *#06# — the EID appears below the IMEI
- iPhone: Settings › General › About › EID
- Android: Settings › About phone › EID, or Settings › Connections › SIM manager
If there is no EID on that screen, the phone has no eSIM chip. That is the quickest compatibility check there is — see How do I Check if My Phone Supports eSIM?
Two Numbers That Get Confused
EID
Identifies the chip. 32 digits. Fixed for the life of the phone, and the same no matter how many plans you install
ICCID
Identifies the plan. Usually 19 or 20 digits. A new one arrives with every eSIM you install, and it is what support needs to look up your order
Your ICCID is shown with each eSIM in My eSIMs and on your order confirmation. When support asks for "the eSIM number", that is normally the one they mean.
Sharing an EID is not a security risk on its own — it identifies hardware, not an account, and it cannot be used to install anything on your phone without your confirmation
