How to Find Your SIM Card Number on iPhone

Whether you're contacting your carrier, transferring service, or troubleshooting a connectivity issue, knowing your SIM card number — technically called the ICCID (Integrated Circuit Card Identifier) — is more useful than most iPhone users realize. The good news: you don't need to eject anything to find it. Here's exactly where to look and what you're actually seeing when you do.

What Is a SIM Card Number (ICCID)?

Your ICCID is a unique 19–20 digit number that identifies your SIM card on a global network. Think of it like a serial number for the card itself — separate from your phone number, your IMEI, or your Apple ID.

Carriers use it to:

• Activate or transfer service
• Replace a lost or damaged SIM
• Troubleshoot network registration issues

It's not a security risk to share with your carrier, but treat it with reasonable care — it's tied to your active mobile account.

Method 1: Find the SIM Number in iPhone Settings

This is the fastest method and works on the vast majority of iPhones. 📱

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

The number listed next to ICCID is your SIM card number. On most iPhones running iOS 10 and later, you can tap and hold the number to copy it — useful if you need to paste it into a carrier form or support chat.

What If You Don't See ICCID?

If the ICCID field is missing from your About screen, a few things could explain it:

• No SIM inserted — iPhones without an active physical or eSIM may not display the field
• eSIM-only configurations — some carrier activations display the EID instead, or list the ICCID under a different label depending on iOS version
• Software glitch — restarting the device sometimes resolves a missing ICCID display

Method 2: Check the Physical SIM Card Tray

If you have a nano-SIM (the physical card), the ICCID is printed directly on it — though in very small text.

1. Use a SIM eject tool or a straightened paperclip
2. Insert it into the small hole on the side of your iPhone (right side on most models)
3. The tray will pop out with the SIM card inside
4. Look for a 19–20 digit number printed on the card itself

This method is more reliable when the Settings route isn't accessible — for example, if the phone won't boot or is locked.

Note: US iPhone 15 models and later ship without a physical SIM tray entirely, relying exclusively on eSIM.

Method 3: Check the Original SIM Card Packaging

When carriers issue a SIM card, the ICCID is printed on the card's packaging sleeve — the larger plastic card the nano-SIM punches out of. If you kept that packaging, the number is printed there in full and is much easier to read than the number on the tiny card itself.

This is particularly handy for:

• Prepaid SIMs purchased at retail
• SIMs issued as part of a device bundle
• International SIMs used for travel

Finding the eSIM ICCID on iPhone 🔍

If you're using an eSIM (a digital SIM embedded in the phone), the process is slightly different:

1. Go to Settings
2. Tap General
3. Tap About
4. Look for ICCID under your eSIM plan — it may appear under a secondary line label if you have dual SIM enabled

On dual SIM iPhones, you may see two separate ICCID entries — one for the physical SIM and one for the eSIM. Each plan has its own unique identifier.

The EID (Embedded Identity Document number) is a different identifier that refers to the eSIM chip itself, not the specific carrier plan loaded on it. Carriers occasionally ask for the EID when setting up a new eSIM remotely.

Variables That Affect Where and How You Find This Number

Not every iPhone user follows the same path here. Several factors shape the experience:

• iOS version — older iOS versions may display the ICCID differently or require an extra navigation step
• Carrier configuration — some carrier-locked iPhones display modified Settings menus
• eSIM vs. physical SIM — purely eSIM devices (like US iPhone 15 and newer) have no card to eject, shifting everything to software-based lookup
• Dual SIM setup — managing two lines means two ICCIDs, and identifying which belongs to which carrier requires knowing your line labels
• Device lock status — a locked or disabled iPhone may not allow Settings navigation, making the physical SIM method or packaging the only option

Why the ICCID Matters in Specific Situations

How Your Specific Setup Changes the Answer

The method that works for you depends on details that vary from one iPhone to the next. Someone using a US iPhone 15 with a single eSIM line has a completely different lookup path than someone with an older iPhone SE running a physical SIM from a regional prepaid carrier. Dual-SIM users in countries where physical + eSIM combinations are common face yet another layer.

Your iOS version, your carrier's configuration of your Settings menu, and whether you're dealing with a physical card, an eSIM, or both — these are the factors that make a single universal answer less useful than understanding the full range of options laid out here.
