Last checked: September 2026
An EID number is a 32-digit identifier for the eSIM chip built into a phone, tablet or watch. It is not the same as an IMEI or ICCID. You can find it on iPhone under Settings, General, About, and on Android under Settings, About phone, sometimes in SIM status or Status.

What an EID number is
The EID (eUICC identifier) is a 32-digit number that identifies the eSIM chip built into a phone, tablet or watch. If your device has an EID, it has an eSIM chip and can use eSIM profiles. If it does not have an EID, it does not support eSIM.
The EID is hardwired into the eSIM chip. It is separate from the IMEI, which identifies the phone itself, and from the ICCID, which identifies a SIM or eSIM profile. You may see the EID written as a long string of digits, sometimes with spaces for readability. It is not a secret code, but you should treat it like other device identifiers and only share it when needed.
How to find your EID on iPhone
On iPhone, go to Settings, then General, then About. The EID is listed there on eSIM-capable models. If you do not see an EID, your iPhone does not have an eSIM chip.
- Open the Settings app.
- Tap General.
- Tap About.
- Scroll down to find EID. You may need to scroll past IMEI and other details.
On some iPhone models, you can also dial *#06# to show the IMEI and, if your phone has an eSIM chip, the EID. The exact layout of the About screen can vary slightly by iOS version, but the EID entry is usually in the same list as the IMEI.
How to find your EID on Android
On Android, the location varies by maker. It is usually under Settings, then About phone, and sometimes inside SIM status or Status. If you cannot find it there, check the device information or status menu.
- Open the Settings app.
- Tap About phone. On some phones this may be called About device or similar.
- Look for SIM status or Status.
- Find EID in the list. If it is not there, your phone may not have an eSIM chip.
Because Android menus differ by manufacturer and model, the exact path can change. If you still cannot find the EID, dial *#06# to see if it appears alongside the IMEI. Not all Android phones show the EID this way, but many do.
EID vs IMEI vs ICCID
IMEI identifies the phone itself. ICCID identifies a SIM or eSIM profile. EID identifies the eSIM chip. They are three different numbers with three different jobs, and you may need different ones for different tasks.
The IMEI is used to identify your physical device, for example when checking if a phone is unlocked or reporting it lost. The ICCID is the serial number of a SIM card or an eSIM profile, and it is what a network uses to activate your line. The EID sits at the hardware level: it tells a provider that your device has an eSIM chip and can host profiles. When you install a travel eSIM, you normally scan a QR code or use an app, and you do not need to type your EID. Some providers may ask for it only for support or troubleshooting.
When you need your EID
You rarely need your EID for everyday use. A travel eSIM QR code does not require you to type your EID. Some providers ask for it only for support, such as when checking device compatibility or resolving an activation issue.
If you are buying a travel eSIM, the main check is whether your phone is eSIM compatible. You can read our guide to see is my phone eSIM compatible. If you have an iPhone, you may also want to check if your iPhone is unlocked, because an eSIM-capable phone can still be carrier locked. eSIM support and being unlocked are separate checks. Once you are ready, you can install an eSIM on iPhone or Android. Keep your EID handy only if a provider asks for it during support.
