There are several reasons you might need your eSIM information. You may be activating a new line, transferring service to another device, troubleshooting with your carrier, or verifying account details during setup.
The confusion usually comes from the fact that an iPhone can display multiple numbers related to an eSIM. Depending on what you’re trying to do, your carrier may ask for your phone number, ICCID, or EID.
If you’re wondering how to find eSIM number on iPhone, knowing which identifier you actually need is the first step.
1. What Is an eSIM Number on iPhone (Phone Number vs ICCID vs EID)?
Many users searching for how to find your eSIM number on iPhone are surprised to discover that there isn’t just one “eSIM number.” Depending on what you’re trying to do, your carrier or device may reference a phone number, ICCID, or EID.
Each serves a different purpose, and knowing the difference can save time when activating service, transferring an eSIM, or troubleshooting account issues.
Phone Number: The Number People Call You On
This is the mobile number associated with your cellular line.
It’s the number you give to friends, family, and businesses, and it’s the number used for calls and text messages. In most situations, this is the number people mean when they ask for your phone number.
However, your phone number is not the same as your eSIM identifier. Carriers can move the same phone number between different SIMs or eSIM profiles over time.
ICCID: Your eSIM Profile’s Unique ID
ICCID stands for Integrated Circuit Card Identifier.
Think of it as the serial number assigned to a specific SIM or eSIM profile. Every eSIM profile has its own ICCID, which helps carriers identify and manage that line on their network.
You may need the ICCID when:
- Troubleshooting activation issues
- Verifying a recently installed eSIM
- Working with carrier support
- Confirming that the correct profile is active
Unlike a phone number, the ICCID is tied to the SIM profile itself rather than the person using it.
EID: The Embedded SIM Hardware ID
The EID, or Embedded Identity Document number, identifies the eSIM hardware built into the iPhone.
Unlike the ICCID, which changes when a new eSIM profile is installed, the EID belongs to the device itself. Carriers often use it when provisioning or activating an eSIM line.
Because it identifies the embedded SIM chip, the EID is usually much longer than a standard phone number or ICCID.
2. How to Find eSIM Number on iPhone Step-by-Step
Apple provides several ways to view eSIM information directly from the device. The best method depends on whether you’re looking for your phone number, ICCID, or EID.
Check eSIM Details in the About Menu
One of the easiest ways to locate eSIM information is through the iPhone’s About screen.
Open: Settings → General → About
Scroll down and look for information such as Phone Number, ICCID, EID, IMEI.
The exact fields displayed can vary depending on your iPhone model, iOS version, and whether an eSIM is currently active.
View Information from Cellular Settings
If your iPhone has multiple lines installed, Cellular Settings can help identify which information belongs to each line.
Open: Settings → Cellular, then select the cellular plan you want to review.
Depending on the carrier and device configuration, you may see details associated with that specific eSIM profile, including the phone number assigned to the line and other account information.
This method is particularly useful when multiple eSIMs are installed on the same device.
Use the Built-In Code to Display EID Information
Another quick option is using the device dialer.
Open the Phone app and enter: *#06#
The iPhone will display important device identifiers, including IMEI information and, on eSIM-compatible models, the EID.
This method is often used when a carrier requests device information during activation or support calls.
3. How to Find eSIM Number on Specific iPhone Models
The process is largely the same across eSIM-compatible iPhones. Whether you’re using an iPhone XS, iPhone 11, iPhone 13, iPhone 14, iPhone 15, or a newer model, the primary navigation path remains within Settings and Cellular menus.
In most cases, you’ll find the relevant information by opening Settings → General → About or reviewing the details associated with an active cellular plan.
One thing to keep in mind is that newer models may display information slightly differently.
For example, U.S. versions of the iPhone 14, iPhone 15, and newer devices are eSIM-only and do not include a physical SIM tray.
As a result, some identifiers may be presented more prominently on the About screen compared with older dual-SIM models.
If you’re researching how to find eSIM number on iPhone 15 or another recent model, the steps remain essentially the same, even though the layout and labeling may vary slightly between iOS versions.
4. Alternative Ways to Find Your eSIM Number
If the information isn’t immediately visible on your iPhone, there are several other ways to locate the details associated with your eSIM.
These methods can be particularly useful if you’re troubleshooting activation issues or need to verify information with your carrier.
Check Your Carrier’s App or Online Account
Many carriers display eSIM-related information directly within their mobile apps or customer account portals.
Depending on the provider, you may be able to view:
- Your phone number
- Active lines
- ICCID information
- Device details
- eSIM activation status
This can be a convenient option if you’re unable to access certain identifiers from the iPhone itself.
Look at Your Original Activation Email
When an eSIM is activated, carriers often send a confirmation email containing important account information.
Reviewing the original activation email may help you locate details such as:
- The phone number assigned to the line
- Activation instructions
- ICCID information
- QR code references
- Account confirmation details
If you’ve recently activated service, this can sometimes be the fastest place to find the information you need.
Contact Carrier Support for Verification
If you’re still unable to locate the correct identifier, your carrier can usually verify it directly.
Customer support representatives may be able to confirm:
- Your phone number
- ICCID
- EID registration status
- Active eSIM profiles
- Device compatibility information
Before contacting support, have your account details available to help speed up the verification process.

5. Common Issues When Finding eSIM Number on iPhone
Many users searching for how to find my eSIM number on iPhone encounter confusion because different identifiers serve different purposes. The following issues are among the most common.
EID or ICCID Field Is Blank
In some situations, the EID or ICCID field may not appear in Settings.
This can happen if:
- No eSIM profile has been installed
- The eSIM has been removed
- The carrier profile failed to activate properly
- The device does not currently have an active eSIM
Restarting the device and checking for carrier updates may help if the information appears to be missing unexpectedly.
Multiple eSIM Profiles: Which Number to Use
Modern iPhones can store multiple eSIM profiles, which sometimes creates confusion.
For example, you may see:
- A primary personal line
- A business line
- A travel eSIM
- Previously inactive profiles
The correct identifier depends on what your carrier is requesting. If they need the active phone number, use the number associated with the currently active line. If they’re requesting technical information, they may instead need the ICCID or EID.
Numbers Don’t Match Carrier Records
Occasionally, information shown on the iPhone may appear different from what a carrier representative sees.
This usually occurs because different identifiers are being compared. A phone number, ICCID, and EID are all separate values and are not expected to match one another.
If there is uncertainty, ask the carrier which identifier they need before providing information.
This can prevent unnecessary confusion during activation, troubleshooting, or account verification.
