What’s an EID Number? Explained
The digital transformation of mobile communication has introduced new terms and concepts, one of which is the EID number. If you’ve recently explored eSIM technology or activated an eSIM on your device, you might have encountered this term. But what exactly is an EID number, and why is it important?
As an experienced traveler and tech enthusiast, I’ve found that understanding these concepts can simplify connectivity, especially when managing multiple carriers or traveling internationally. This guide explains everything you need to know about EID numbers and how they play a crucial role in the eSIM ecosystem.
What is an EID Number?
The term EID stands for Embedded Identity Document, and it’s a unique identifier associated with the eSIM in your device. Think of it as the digital equivalent of a traditional SIM card’s serial number but designed for the world of eSIM technology.
An EID number is typically a 32-digit alphanumeric code that’s globally unique to each device. It’s embedded into your device’s hardware, making it a critical component of eSIM management. This identifier allows mobile network operators (MNOs) to provision and activate eSIM profiles remotely, without requiring a physical SIM card.
In simpler terms, the EID number acts as your device’s passport in the digital world of eSIMs, enabling seamless activation and management of cellular plans.
Why is an EID Number Important?
The EID number is the backbone of eSIM functionality, and its importance lies in its ability to:
1. Enable eSIM Activation
When you purchase an eSIM plan, your carrier uses the EID number to link the plan to your device. This ensures that the correct cellular profile is provisioned and activated.
2. Support Multiple Profiles
Since eSIMs can store multiple profiles, the EID helps carriers distinguish between devices and assign profiles accurately.
3. Enhance Security
The EID ensures that only authorized profiles are installed on your device, reducing the risk of unauthorized access or fraud.
4. Simplify Carrier Switching
For frequent travelers or users managing multiple numbers, the EID facilitates smooth transitions between carriers by acting as a universal identifier.
In essence, the EID number simplifies mobile connectivity, offering flexibility and security for users in an increasingly connected world.
How is an EID Different from an IMEI?
While the EID and IMEI numbers may seem similar, they serve distinct purposes in mobile technology. Let’s break down the differences:
IMEI (International Mobile Equipment Identity)
- A 15-digit number unique to your device.
- Used primarily to identify devices on a mobile network.
- Helps carriers block stolen or lost phones.
EID (Embedded Identity Document)
- A 32-digit alphanumeric code unique to your eSIM.
- Enables activation and management of eSIM profiles.
- Specifically associated with eSIM technology.
In short, while the IMEI identifies your device as a whole, the EID is specifically tied to the eSIM functionality within that device.
Where to Find Your EID Number?
Finding your EID number is a straightforward process, although it may vary slightly depending on your device. Here’s how you can locate it on popular platforms:
On iPhone
- Open the Settings app.
- Navigate to General > About.
- Scroll down to the EID section to find your unique identifier.
On Android
- Open the Settings app.
- Go to Network & Internet > Mobile Network (or similar, depending on your device).
- Look for the EID listed under eSIM settings.

On Wearables
If you’re using a smartwatch or similar device with eSIM functionality:
- Open the companion app on your smartphone.
- Go to Cellular Settings or eSIM Management.
- Locate the EID in the settings menu.
It’s worth noting that your device may also display the EID on its original packaging or in the user manual, providing an additional reference point.
Common Use Cases for EID Numbers
The EID number has practical applications that enhance the eSIM experience for users. Let’s explore some common scenarios where the EID plays a pivotal role:
Activating an eSIM Plan
When activating an eSIM plan, your carrier may ask for your EID number to assign the correct profile to your device. This is a critical step in ensuring seamless connectivity.
Switching Carriers
For users who frequently switch between carriers—especially international travelers—the EID simplifies the process by enabling carriers to remotely configure your eSIM.
Troubleshooting Connectivity Issues
If you encounter issues with your eSIM, providing the EID to your carrier can help them identify and resolve the problem quickly.
Device Replacement or Transfer
When transferring an eSIM profile to a new device, the EID ensures that the profile is securely provisioned to the correct hardware.
These use cases highlight the EID’s role in streamlining eSIM functionality, making it an indispensable part of modern mobile communication.
