An EID is the unique 32-digit serial number of the eSIM chip built into your phone — think of it as the permanent ID of the little embedded chip that stores your eSIM profiles. Some providers ask for it when you set up or transfer an eSIM. Finding it takes about ten seconds.
What EID stands for
EID stands for eUICC Identifier (eUICC = embedded Universal Integrated Circuit Card — the technical name for the eSIM chip). It's a 32-digit number that's permanently tied to your device's hardware, not to any particular plan or carrier. Your phone has exactly one EID for its whole life, no matter how many eSIM profiles you add or remove.
That's the key difference from an ICCID, which identifies a specific eSIM *plan*. One EID (the chip) can hold many ICCIDs (the plans) over time.
How to find your EID
On iPhone
- 1Open Settings
- 2Tap General → About
- 3Scroll down to EID
- 4Tap and hold to copy it
You can also dial \*#06# on the keypad — the EID appears alongside your IMEI numbers.
On Android (Pixel, Samsung, and others)
The universal method: open the phone dialer and enter \*#06#. A screen appears listing your device identifiers, including the EID.
By brand, through settings:
- Google Pixel: Settings → About phone → SIM status (or scroll for EID)
- Samsung Galaxy: Settings → About phone → Status information → look for EID
- Other Android: Settings → About phone → scroll to EID, or use \*#06#
The \*#06# dialer code is the fastest route and works on nearly every phone.
When you actually need your EID
You won't need it for a normal travel eSIM purchase — most providers (Wanderly included) just send you a QR code to scan, no EID required. You may be asked for it when:
- A carrier pre-provisions an eSIM to your specific device
- You're transferring or troubleshooting an eSIM with carrier support
- A business or family plan assigns profiles to known devices in advance
For scan-and-go travel eSIMs, you can usually ignore it entirely.

Frequently Asked Questions
What is an EID number? The EID (eUICC Identifier) is a permanent 32-digit number that identifies the eSIM chip built into your device. It is one per device and never changes when you add or remove eSIM plans.
How do I find my EID number? On iPhone: Settings > General > About, then scroll to EID. On most Android phones: Settings > About phone > SIM status, or dial *#06#.
Is the EID the same as the IMEI? No. The IMEI is a 15-digit number identifying the handset; the EID is a 32-digit number identifying the eSIM chip inside it. A phone has both.
Is the EID the same as the ICCID? No. The ICCID identifies a single SIM profile or plan and changes with each plan; the EID identifies the chip and never changes.
Do I need my EID to buy a travel eSIM? Usually not. Travel eSIM QR codes are typically not device-bound, so you only need an unlocked, eSIM-capable phone.
Is it safe to give someone my EID? It is safe to share with your carrier or eSIM provider. The number alone cannot be used to install a profile or access your data.
