Where to find your SIM card number on your phone

Your SIM card number — officially called the ICCID (Integrated Circuit Card Identifier) — is printed on the physical card itself and also stored in your phone's settings. The fastest way to find it is to look at the card directly. Open your phone's SIM card slot (usually on the side of the device), remove the tray, and look at the small card. You will see a long number printed on the front, typically starting with 89. That is your SIM card number.

If you cannot remove the SIM card or prefer not to, you can find the same number in your phone's settings without touching the hardware at all. The location varies slightly between Android and iPhone, but both store this information in the device information section.

Key Takeaways

  • Your SIM card number is printed directly on the physical card and is a long string of digits starting with 89.
  • On iPhone, go to Settings > General > About and scroll to find ICCID listed as your SIM card number.
  • On Android, the path varies by manufacturer, but Settings > About Phone > SIM Status or Settings > Device Info usually shows it.
  • If your phone is locked or you cannot access settings, removing the SIM tray and reading the card directly is the simplest option.

Finding your SIM card number on iPhone

Open the Settings app and tap General. Scroll down and tap About. On this screen, look for a field labeled ICCID — this is your SIM card number. It will be a long string of numbers. Write it down or take a screenshot if you need to keep it.

If you do not see ICCID listed, your phone may not have a physical SIM card installed, or it may be using an eSIM (a digital SIM stored in software). If you have an eSIM, the ICCID will still appear in this same location, but the card itself will not be removable.

Finding your SIM card number on Android

The exact path depends on your phone's manufacturer, but the information is always in the device settings. Start by opening Settings and look for a section called About Phone or Device Info. Tap it, then look for SIM Status, SIM Information, or Phone Identity. One of these sections will display your ICCID.

If you cannot find it in those locations, try Settings > Network & Internet > SIM Manager or Settings > Dual SIM & Mobile Network, depending on your device. Some manufacturers like Samsung, Google, and OnePlus place this information in slightly different spots. If you are still stuck, searching your phone's settings for the word "ICCID" will usually take you directly to the right screen.

Reading the number directly from the SIM card

If your phone is powered off, locked, or you straightforward prefer the most straightforward method, you can read the number straight from the card. Locate the SIM card slot on the side or back of your phone — it is usually a small rectangular opening. Use a SIM ejector tool (a thin metal pin that often comes with your phone) or a straightened paperclip to gently push into the hole next to the slot. The tray will pop out slightly.

Pull the tray out completely and remove the SIM card. Look at the front of the card. You will see a long number printed in small text, usually starting with 89. This is your ICCID. The number is typically 19 or 20 digits long. Once you have written it down, reinsert the card into the tray, push the tray back into the phone until it clicks, and you are done.

What to do if you cannot find your SIM card number

If your phone does not show an ICCID in settings and you cannot physically access the SIM card, contact your mobile carrier directly. They can look up your SIM card number using your phone number and account information. Call the customer service number on your phone bill or visit a store in person with your ID.

If you have lost your SIM card or it is damaged, your carrier can issue you a replacement. The new card will have a different ICCID, but your phone number and service will remain the same. There is usually no charge for a replacement SIM card, though some carriers may charge a small fee.

Why you might need your SIM card number

Your SIM card number is sometimes requested when you switch carriers, replace a lost or damaged SIM card, or troubleshoot network problems with your carrier. It is also used if you are setting up international roaming or activating a new device on an existing account. Most of the time, your carrier can look this up on their own, but having it handy speeds up the process.

Do not confuse your SIM card number with your phone number or your phone's IMEI (a different identifier for the device itself). Your SIM card number is specific to the card; your phone number is what people use to call you; and your IMEI identifies the physical phone hardware.

Frequently Asked Questions

Is my SIM card number the same as my phone number?

No. Your phone number is what people dial to reach you. Your SIM card number (ICCID) is a separate identifier for the card itself. If you move your SIM card to a different phone, your phone number stays the same, but the SIM card number does not change.

Can I find my SIM card number if my phone is off?

Yes. The only way to find it without powering on the phone is to remove the SIM card and read the number printed on the front of the card itself. You will need a SIM ejector tool or a thin object like a paperclip to pop out the tray.

What if my SIM card number starts with something other than 89?

Most SIM card numbers start with 89, but some older cards or cards from certain carriers may start with different digits. As long as the number is long (typically 19 to 20 digits) and appears in your phone's SIM information section, it is correct.

Do I need my SIM card number to switch carriers?

Not always. Your new carrier usually only needs your phone number and account information. However, having your SIM card number on hand can speed up the process if the carrier asks for it during setup or troubleshooting.

Will my SIM card number change if I get a replacement card?

Yes. Each physical SIM card has its own unique ICCID. If your carrier sends you a replacement card, the new card will have a different SIM card number, but your phone number and service will remain unchanged.
