What Is an EID on an iPhone?

EID stands for Embedded Identity Document. It is a unique 32-digit number built into your iPhone. This number is linked to your phone’s eSIM, which is a digital SIM card stored inside the device.

Unlike a physical SIM card, an eSIM cannot be removed. The EID stays fixed to your iPhone for its entire lifetime. Apple assigns this number during manufacturing, and every eSIM-compatible iPhone has its own EID.

Mobile carriers use the EID to:

• Activate an eSIM plan
• Identify the correct device
• Help with network or activation issues

Most people never need this number daily. It is usually required only when setting up a new eSIM, changing carriers, or using travel eSIM services.

EID is not the same as IMEI or serial number.

• IMEI identifies the phone itself
• Serial number is used for warranty and support
• EID is used only for eSIM identification

How to Find Your EID Using iPhone Settings

This is the quickest and most common method.

1. Open Settings
2. Tap General
3. Select About
4. Scroll down until you see EID

The EID will appear as a long 32-digit number.
You can press and hold the number to copy it if you need to share it with your carrier.

This method works on all modern iPhones that support eSIM and usually takes less than a minute.

Finding EID Before iPhone Setup Is Complete

If your iPhone is brand new and not set up yet, you can still view the EID.

1. Turn on the iPhone
2. Stay on the Hello welcome screen
3. Look for a small ⓘ (information) icon at the bottom
4. Tap the icon

A screen will appear showing important device details, including the EID. This is helpful if you need to activate an eSIM before finishing setup.

Other Ways to Find Your EID on an iPhone

Sometimes you may not be able to access the Settings app. In those cases, these alternative options can help.

Using a Computer

• Connect your iPhone to a Mac or Windows PC
• On macOS:
  • Open Finder (or iTunes on older versions)
• On Windows:
  • Open iTunes or Apple Devices app

Select your iPhone from the sidebar. Click on the device information until different identifiers appear. Keep clicking until the EID is shown.

Using Your Apple ID Account Online

This method works even if the iPhone is not with you.

1. Open a web browser
2. Go to account.apple.com
3. Sign in with your Apple ID
4. Open the Devices section
5. Select your iPhone from the list

The EID will be displayed in the device details.

Using Another Apple Device

If you have another iPhone or iPad signed in with the same Apple ID:

1. Open Settings
2. Tap your Apple ID name
3. Scroll down to see your devices
4. Select the iPhone you need

The EID will appear in the device information.

Checking the Original iPhone Box

If your iPhone does not turn on, check the retail box.

• Look at the label on the back of the box
• Along with the serial number and IMEI, the EID may also be printed there

This is why it is always a good idea to keep your iPhone box safe.

What to Do If EID Does Not Appear

If you cannot find the EID:

• Restart your iPhone and check again
• Make sure the phone supports eSIM
• Connect to Wi-Fi and try once more
• Update to the latest version of iOS

If the number still does not show up, contacting Apple Support or your mobile carrier is the safest option.
