How To Find EID Number: Complete Technical Guide For IOS And Android Devices
An EID (Embedded Identity Document) number is a 32-digit serial number unique to your device's eUIM (embedded Universal Integrated Circuit Card) chip, essential for activating digital eSIM profiles. You can locate this identifier directly through your smartphone operating system settings menu, via the physical retail packaging barcode, or by dialing a specific carrier string if supported by your hardware architecture.
Pre-Operation & Physical Device Checklist
Before attempting to locate your Embedded Identity Document, understanding the underlying hardware infrastructure ensures you target the correct settings interface. The EID is fundamentally tied to the device's mainboard architecture, distinguishing it from standard physical subscriber identity modules (SIMs) and the International Mobile Equipment Identity (IMEI) number used for network tracking.
- Essential Tools & Materials: A fully charged smartphone (iOS 12.1+ or Android 9.0+), device passcode or biometric authentication access, and the original retail product box if software navigation fails.
- Prerequisite Knowledge & Standards: Familiarity with distinguishing between IMEI, MEID, ICCID, and EID numbers to prevent configuration errors during carrier provisioning.
- Estimated Duration & Budget: The entire diagnostic and retrieval process takes between 60 seconds and 3 minutes, incurring zero financial cost.
Step-by-Step Procedure to Locate Your EID Number
Step 1: Accessing the Device About Menu
Navigate to your primary operating system settings interface to initiate the hardware inquiry. For Apple iOS users, open the Settings application, tap on General, and select About. Scroll down past the serial number and IMEI fields until you locate the 32-digit EID string. For Android users, open Settings, scroll to the bottom, tap About Phone or About Device, and look for Status Information or Hardware Information depending on your manufacturer skin (One UI, Pixel UI, OxygenOS).
Pro-Tip: If the text string is too long to copy manually, press and hold your finger on the EID number field within most modern mobile operating systems to trigger a contextual copy-to-clipboard prompt.
Step 2: Utilizing USSD Dialing Codes
If graphical user interfaces are unresponsive or you are troubleshooting a restricted device state, use the hardware keypad to query the baseband processor directly. Open the native Phone application, tap the dialer pad, and input the string star pound zero six pound (*#06#). This universal hardware command triggers an overlay dialog box that outputs your device identifiers directly from the radio firmware, displaying the IMEI, barcode, and the EID number sequentially if an eUIM chip is present.
Step 3: Inspecting Retail Packaging and Documentation
When software navigation is entirely inaccessible due to a corrupted operating system or a locked screen, physical hardware auditing provides an alternative retrieval vector. Locate the original retail box your smartphone arrived in. Scan the exterior white inventory label, which contains a series of scannable barcodes and human-readable text strings. The EID is typically printed alongside the IMEI barcodes, identified explicitly by the label "EID" followed by the 32-digit numeric sequence.

Comparative Analysis of Mobile Device Identifiers
| Identifier Acronym | Full Nomenclature | Bit Length / Format | Primary Technical Function |
|---|---|---|---|
| EID | Embedded Identity Document | 32 Numeric Digits | Identifies the physical eUIM chip to download and manage digital eSIM profiles. |
| IMEI | International Mobile Equipment Identity | 15-17 Numeric Digits | Identifies the physical cellular hardware device to network towers for security and tracking. |
| ICCID | Integrated Circuit Card Identifier | 19-20 Numeric Digits | Identifies the specific SIM profile (physical or digital) assigned by a carrier. |
| MEID | Mobile Equipment Identifier | 56-Bit Hexadecimal | Legacy CDMA hardware identifier used primarily in older network infrastructures. |
Common Troubleshooting & Field Fixes
- Root Cause: The EID field is completely missing or blank within the smartphone About menu.
- Actionable Fix: This typically indicates that your specific hardware variant lacks an embedded eUIM chip or has a disabled baseband module. Verify your exact regional model number against manufacturer specifications, or perform a complete network settings reset.
- Root Cause: The *#06# dialer code only displays the IMEI and barcode without showing an EID number.
- Actionable Fix: Your device hardware relies entirely on a physical nano-SIM slot and does not support dual-SIM dual-standby (DSDS) configurations with integrated eSIM functionality. You must use a physical SIM card or upgrade to an eSIM-compatible device model.
- Root Cause: The 32-digit EID number is truncated or obscured on the physical retail box label.
- Actionable Fix: Use a high-resolution smartphone camera with macro focus to photograph the barcode, then zoom in on the digital image, or power on the device in recovery mode to pull the hardware strings via a connected computer terminal.
Frequently Asked Questions
What is the difference between an IMEI and an EID number?
The IMEI tracks the physical cellular radio hardware for network security and device blocking, whereas the EID specifically identifies the embedded eUIM chip used exclusively for storing and managing downloadable digital eSIM profiles. While every cellular phone has an IMEI, only devices featuring modern eSIM architecture possess an EID number.
Can I activate an eSIM without knowing my EID number?
No, network carriers and digital service providers require your 32-digit EID number to securely bind a new digital profile to your specific hardware chip during the remote provisioning process. Providing an incorrect or missing EID will result in provisioning failures and activation errors.
Is my EID number sensitive information that I should keep secret?
Your EID number is technically considered secure hardware metadata, but it is generally safe to share with authorized cellular carriers when you are actively setting up a new line or transferring an existing mobile plan. However, you should avoid posting your EID publicly on open forums to prevent spoofing or unauthorized profile mapping attempts.
Why do some phones have an EID while older models do not?
The EID standard was introduced alongside modern GSMA specifications for remote SIM provisioning to eliminate the physical logistics of swapping plastic subscriber cards. Older smartphone models manufactured prior to the widespread adoption of eSIM technology simply lack the necessary hardware eUIM microchip required to generate an EID.
