Where to find your SIM card number on your phone

Your SIM card number — also called the ICCID (Integrated Circuit Card Identifier) — is printed on the physical SIM card itself and also stored in your phone's settings. The fastest way to find it depends on whether you want to look at the card directly or check your phone.

If you have the SIM card in front of you, look at the back. You will see a long number printed there, usually starting with 89. That is your SIM card number. It is typically 19 or 20 digits long. If the card is still in your phone and you cannot remove it easily, you can find the same number in your phone's settings without taking anything apart.

The number you are looking for is different from your phone number and your IMEI (the unique identifier for your phone itself). Your SIM card number identifies the card that your carrier issued to you, and it stays the same even if you switch phones.

Key Takeaways

  • Your SIM card number is printed on the back of the physical card and is usually 19 or 20 digits long, starting with 89.
  • On Android phones, you can find it in Settings > About Phone > SIM Status or SIM Card Information.
  • On iPhones, go to Settings > General > About and look for the ICCID field.
  • Your SIM card number is different from your phone number and your phone's IMEI number.
  • You may need your SIM card number when switching carriers, troubleshooting connection problems, or replacing a damaged card.

Finding your SIM card number on Android

On most Android phones, open Settings and scroll down to find "About Phone" or "About Device." Tap it, then look for "SIM Status" or "SIM Card Information." The screen will show your SIM card number listed as ICCID. Write it down or take a screenshot.

If you do not see a SIM Status option, try Settings > Network & Internet > SIM Cards or Settings > Dual SIM and Mobile Network. The exact path varies by manufacturer — Samsung, Google Pixel, OnePlus, and others organize these menus slightly differently. If you are stuck, searching "[your phone model] SIM card number" will show you the exact steps for your device.

Some carriers also let you find this information in their mobile app. Open your carrier's app, go to Account or Settings, and look for SIM information or device details. This is useful if you are having trouble navigating your phone's settings.

Finding your SIM card number on iPhone

On any iPhone, open Settings, tap General, then tap About. Scroll down until you see "ICCID" — that is your SIM card number. It will be a long string of digits. You can tap it to copy it to your clipboard if you need to paste it elsewhere.

If you are using an eSIM (a digital SIM that does not require a physical card), the process is the same — the ICCID field will still show your SIM card number. iPhones with dual SIM capability will show both numbers if you have both a physical SIM and an eSIM active.

Removing and reading the physical SIM card

If you prefer to look at the card directly, you will need to remove it from your phone. Most phones have a small tray on the side that holds the SIM card. Look for a tiny hole next to the tray and use a SIM ejector tool (a small metal pin that often comes with your phone) or a straightened paperclip to push the tray out gently.

Once the tray is out, lift the SIM card carefully and look at the back. The number printed there is your SIM card number. It is usually in a smaller font than the numbers on the front. Write it down or photograph it. Slide the card back into the tray, push the tray back into your phone until it clicks, and you are done.

Do not force the tray — if it does not slide out easily, stop and use the settings method instead. Some phones have non-removable SIM trays or use eSIM only, so the physical card may not be accessible.

Why you might need your SIM card number

Your carrier may ask for your SIM card number when you contact them about service problems, especially if your phone is not connecting to the network properly. They use it to look up your account and confirm which SIM card is registered to you.

If you are switching to a new carrier, they may ask for your SIM card number as part of the porting process, though they usually just need your phone number. If your SIM card is damaged or lost, your carrier will need the old SIM card number to deactivate it and issue you a replacement.

Some people also keep a record of their SIM card number for their own records, especially if they travel internationally or use multiple SIM cards in different countries.

The difference between SIM card number, phone number, and IMEI

These three numbers are straightforward to confuse because they all identify parts of your mobile service, but they are completely different. Your phone number is what people call or text you — it is tied to your SIM card but changes if you switch carriers or get a new SIM. Your SIM card number (ICCID) identifies the physical or digital card your carrier issued. Your IMEI is a unique identifier for your phone hardware itself and does not change even if you swap out the SIM card.

If you need to find your IMEI instead, you can usually find it in the same About Phone or About section where the SIM card number is listed. You can also dial *#06# on most phones and the IMEI will appear on screen when ready.

Frequently Asked Questions

What if I cannot find the SIM card number in my phone settings?

Try restarting your phone first, then check the settings again. If the option still does not appear, your phone may not have a removable SIM card or the SIM card may not be recognized. Contact your carrier — they can look up your SIM card number using your phone number or account information.

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

No. Your phone number is what people use to reach you. Your SIM card number is a separate identifier for the card itself. You can keep the same phone number if you switch SIM cards, and you can use the same SIM card in different phones.

Can I find my SIM card number if the card is damaged?

If the card is still in your phone and working, you can find the number in your phone settings. If the card is physically damaged and not working, contact your carrier — they have a record of your SIM card number in their system and can help you get a replacement.

Do I need my SIM card number to switch carriers?

Usually not. Most carriers only need your phone number and account information to port your service. However, some carriers may ask for your SIM card number during troubleshooting or to confirm your account, so it is useful to have it on hand.
