What Is an EID Number?

The EID, or Embedded Identity Document, is a crucial piece of the eSIM puzzle. This unique 32-digit number helps connect your smartphone to cellular networks. But what exactly is an EID, and why does your iPhone, Android or other device need one? Let’s unravel the details in this complete guide to EID numbers.

What Is EID Number?

An EID number stands for Embedded Identity Document number. It’s a unique 32-digit code assigned to the eSIM module inside eSIM-compatible smartphones like iPhones and Android devices.

You can think of the EID as the digital version of the ICCID SIM number that allows carriers to identify and authenticate an eSIM. Without an EID, it wouldn’t be possible for networks to recognize a device’s built-in eSIM in order to connect it to mobile data and telephony services.

The EID number plays a pivotal role in the eSIM equation. It ensures seamless remote provisioning and switching between network profiles. Furthermore, the EID enables reliable access control and security when connecting a device to cellular networks.

So in a nutshell, the EID gives carriers the ability to properly identify eSIMs in various phones and tablets in order to deliver smooth network connectivity, over-the-air profile setups and accurate billing.

Why Do You Need an EID Number?

Given that the EID facilitates communications between carriers and your device’s integrated eSIM, it essentially allows you to take full advantage of eSIM capabilities.

Without an EID, mobile operators wouldn’t be able to recognize your eSIM in order to provision and activate service profiles. As a result, you wouldn’t benefit from key eSIM features such as:

  • Over-the-air activation of cellular plans
  • Streamlined carrier switching
  • Simultaneous dual-SIM functionality
  • Remote profile management

Additionally, the EID enables reliable network access control and security. It uniquely identifies your eSIM module to prevent identity theft while also blocking unauthorized profile installations.

So in summary, you need an EID number because:

  • It enables carriers to correctly identify and authenticate your eSIM
  • Allows over-the-air profile activation and management
  • Unlocks full eSIM dual-SIM capabilities
  • Prevents fraud through unique identification

While invisible to users, EID numbers do the heavy lifting behind the scenes—so you can easily add, switch or manage mobile plans remotely.

How to Find Your EID Number

Wondering how to check your phone’s EID number? The good news is that it’s easy to locate this unique identifier on both iPhones and Android devices.

Here are the step-by-step instructions to find your EID:

Finding the EID Number on an iPhone

Finding the EID Number on an iPhone
  1. Open the Settings app
  2. Tap General
  3. Scroll down and select About
  4. Look for the EID section. Your iPhone’s 32-digit EID number will be shown here

Alternatively, you might spot the EID printed on the iPhone’s packaging, near the IMEI and serial number.

Locating EID Numbers on Android Phones

Finding the EID Number on Samsung

The most straightforward method is checking the EID on your Android phone’s box—it’s generally printed near the barcode.

If your EID isn’t on the packaging, don’t worry. You can still uncover the number through your device settings:

  1. Launch Settings
  2. Choose About Phone
  3. Select Status or IMEI Information
  4. Scroll through the status data to find your unique EID number

That covers finding your EID on current iPhone and Android handsets. But what about other devices?

Finding The EID Number on Tablets and Smartwatches

More and more smart gadgets are adopting eSIM connectivity. Fortunately, tracking down the EID number on tablets and wearables like the Apple Watch is very similar:

Apple iPad: Head to Settings > General > About and check the EID details here
Apple Watch: Open the Watch app on your iPhone, go to General > About and locate the EID number

As with smartphones, double-checking the packaging is an easy way to discover iPad, smartwatch and other device EID numbers.

EID Number Security Features

Given that EID numbers enable remote over-the-air activations and profile installations, it’s pivotal that they provide a high level of security.

EIDs uniquely identify devices while also securing provisioning processes and connections. Key aspects include:

Encryption

EID data is encrypted from end-to-end during transmissions between networks and devices. This prevents potential interceptions, effectively blocking attackers from accessing sensitive identification data.

Authentication

The EID allows carriers to reliably authenticate eSIM-based devices attempting to connect to mobile networks. As a result, only authorized devices can access data plans and connectivity.

Unique Identification

Each EID number is completely unique to every eSIM globally. This singular identification capability thwarts cloning attempts while also reducing the potential for identity theft.

Secure Provisioning

On top of encryption, secure data channels enabled by EIDs ensure only legitimate carrier profiles from trusted operators can be installed on devices.

Remote Profile Management

EIDs facilitate reliable remote profile activation, deactivation and switching. Furthermore, access control enabled by EIDs focuses on authorized profile changes only.

Thanks to these pivotal security pillars enabled by EID numbers, users can provision, manage and switch eSIMs wirelessly with complete peace of mind.

Common EID Number Queries

Given that eSIM adoption is still rapidly accelerating globally, many users have questions surrounding EID specifics.

Here are answers to some frequently asked questions:

What’s the Difference Between EID and ICCID Numbers?

ICCID is an acronym for Integrated Circuit Card Identifier. It’s the unique serial number assigned to traditional physical SIM cards.

As outlined earlier, EID means Embedded Identity Document. EIDs are exclusive to eSIMs and fundamental for identification and profile handling.

Why Won’t My iPhone EID Number Show?

If you can’t view the EID number on your iPhone, the handset likely doesn’t offer eSIM support. Alternatively, you might not have activated an eSIM profile yet. Double-check your model supports eSIM capabilities and contact Apple for assistance if issues persist.

Is My EID Number the Same as the SIM Number?

No. The SIM number refers to a physical SIM card’s distinctive ICCID. EID numbers are completely separate identifiers exclusive to eSIM modules integrated into modern smartphones, tablets and watches.

While invisible to everyday users, EID numbers deliver the foundations for all eSIM-based connectivity. Memorizing the 32-digit code isn’t essential. However, knowing how to find your EID can simplify troubleshooting and installations.

Final Thoughts

As eSIM adoption accelerates globally, EID numbers provide the vital behind-the-scenes identification and security pillars enabling game-changing wireless flexibility.

Whether you want to easily switch carriers or run dual-SIM setups, the unique EID assigned to your device ensures seamless network access and hassle-free remote profile management.

So while you might not interact directly with EID figures frequently, memorizing the number location in your iPhone, Android or tablet settings can save time when installing eSIMs down the track.

Overall, EID numbers form the backbone of identification and authentication for modern eSIM arrangements across smartphones, tablets and wearables. Understanding these pivotal embedded IDs will prove valuable as more gadgets adopt eSIM capabilities moving forward.
