How to Find Your SIM Card Number (ICCID) on Any Device

Your SIM card number — technically called the ICCID (Integrated Circuit Card Identifier) — is a unique 19 or 20-digit string that identifies your SIM on the network. It's not the same as your phone number, and most people never need it until suddenly they do: activating a new plan, troubleshooting a network issue, transferring service, or filing a support ticket with your carrier.

Here's where to find it, depending on your device and setup.

What Is a SIM Card Number, Exactly?

The ICCID is printed on the SIM card itself and stored in your phone's settings. Think of it as a serial number for the physical (or virtual) SIM — it tells your carrier which card is authorized on their network.

A few things worth knowing upfront:

• The ICCID is not your phone number (MSISDN)
• It's not your IMEI number (that identifies the device, not the SIM)
• It typically starts with 89, which is the international telecom identifier prefix
• On eSIMs, there's no physical card — but the ICCID still exists in software

Method 1: Check Your Phone's Settings 📱

This is the fastest method for most people, and it works without removing the SIM.

On iPhone (iOS)

1. Open Settings
2. Tap General
3. Tap About
4. Scroll down to find ICCID

The number appears directly in that list, usually near your IMEI and phone number.

On Android

The path varies by manufacturer and Android version, but the most common route is:

1. Open Settings
2. Tap About Phone (sometimes under General Management)
3. Tap Status or SIM Card Status
4. Look for ICCID or SIM Card Number

On Samsung devices, the path is typically: Settings → About Phone → Status Information → ICCID

On Google Pixel devices: Settings → About Phone → ICCID

If you can't find it through the standard path, use your phone's built-in search function and type "ICCID" — most modern Android versions will surface the setting directly.

Method 2: Read It Off the Physical SIM Card

If you still have the original SIM card packaging — the credit card-sized carrier it came on — the full ICCID is usually printed there, sometimes as a number and a barcode.

If you want to read it off the SIM card itself:

1. Power down your phone
2. Eject the SIM tray using the tool (or a straightened paperclip)
3. The number printed on the chip is the ICCID — though it may be abbreviated to the last 13 digits on smaller nano-SIMs

📌 The full 19–20 digit number is more reliably found in settings than on the card itself, where space constraints sometimes truncate it.

Method 3: Check Through Your Carrier Account

Most carriers display your ICCID in your online account dashboard or app:

• Log into your carrier's website or app
• Navigate to My Account → Devices or My Plan → SIM Details
• The ICCID is typically listed alongside your phone number and device info

This method is especially useful if you're managing a line remotely, dealing with a lost phone, or working with a business account that has multiple SIMs.

Method 4: Dial a USSD Code (Carrier-Dependent)

Some carriers support USSD codes that return SIM information. These vary by carrier and region, so there's no universal code — but your carrier's support page or documentation will list whether one is available. This method is more common in some international markets than in the US or UK.

Comparing Methods at a Glance

eSIM: No Card, But Still a Number

If your device uses an eSIM (embedded SIM), there's no physical card to check — but the ICCID still exists. Find it the same way: Settings → About → ICCID on iPhone, or the equivalent path on Android.

One key variable here: if your device is running dual SIM (one physical, one eSIM), your settings will show two separate ICCIDs. Make sure you're referencing the right one for the line you're working with.

Why the "Right" Method Depends on Your Situation

Which approach actually works for you comes down to several factors:

• Device type — iPhone and Android settings paths differ, and manufacturer skins (Samsung One UI, Xiaomi MIUI, etc.) sometimes reorganize menus
• Android version — older versions may label the field differently or bury it deeper
• Physical SIM vs. eSIM — changes whether you can cross-reference a card
• Whether your phone is functional — a locked, broken, or inaccessible device may require the carrier account method
• Carrier and region — affects whether USSD codes or account dashboards surface full SIM details

Someone troubleshooting a network issue on a newer dual-SIM Android flagship will have a different experience finding and interpreting their ICCID than someone trying to retrieve it for an old SIM they can no longer slot in. The information itself is the same — it's the retrieval path and what you do with it that shifts based on your specific setup.
