Where to find your SIM number on your phone

Your SIM card number — also called the ICCID or Integrated Circuit Card Identifier — is printed on the SIM card itself and also stored in your phone's settings. The fastest way to find it is to open your phone's settings, go to About Phone (on Android) or General > About (on iPhone), and look for a field labeled "ICCID" or "SIM card number". If that field is blank or missing, your phone may not display it, and you will need to check the physical card instead.

To find the number on the actual SIM card, remove it from your phone using the SIM ejector tool that came with your device, or use a straightened paperclip. The SIM card is a small rectangular chip, usually gold or silver colored. The ICCID is a 19 or 20-digit number printed on the front of the card. Write it down or take a photo — you will need this number if your carrier asks for it or if you are switching phones.

Key Takeaways

  • Your SIM card number (ICCID) is a 19 or 20-digit code printed on the physical card and sometimes stored in your phone's settings.
  • On Android, check Settings > About Phone and look for "ICCID" or "SIM card number"; on iPhone, go to Settings > General > About and scroll to find it.
  • If your phone does not display the number in settings, remove the SIM card using the ejector tool and read the printed digits directly from the card.
  • Your SIM number is different from your phone number — the SIM number identifies the card itself, while your phone number is what people call you.

Android: Finding your SIM number in settings

Open the Settings app on your Android phone. Scroll down and tap "About phone" (the exact wording varies by manufacturer — Samsung calls it "About device", while other brands may say "Phone information"). Once you are in the About section, look for a field labeled "ICCID", "SIM card number", or "SIM ICCID". The 19 or 20-digit number displayed there is your SIM card number.

If you do not see this field, your phone may not display the ICCID in settings. This is common on older Android versions or certain carriers. In that case, you will need to remove the SIM card and read the number printed on it. Some Android phones also let you find this information by dialing *#06# — a code that displays device and SIM information on the screen — though not all carriers support this method.

iPhone: Finding your SIM number in settings

Open the Settings app and tap "General". Scroll down and tap "About". On the About screen, scroll through the list until you find "ICCID" or "SIM card number". The number shown is your SIM card identifier. This method works on all recent iPhone models running iOS 12 or later.

If you do not see the ICCID listed, your iPhone may not display it in settings — this can happen if your SIM card is very old or if your carrier has restrictions. Remove the SIM card using the ejector tool (a small metal pin that came in your iPhone box) and check the printed number on the card itself. You can also contact your carrier directly; they have your SIM number on file and can provide it over the phone.

Reading the number directly from your SIM card

If your phone does not show the SIM number in settings, you will need to remove the card. Locate the SIM card tray on the edge of your phone — it is usually a small slot with a tiny hole next to it. Insert the SIM ejector tool (or a straightened paperclip) into the hole and push gently until the tray pops out. Pull the tray all the way out and remove the SIM card.

Look at the front of the SIM card. You will see a series of numbers printed on it. The longest number — typically 19 or 20 digits — is your ICCID or SIM card number. It usually starts with "89" followed by a country code. Write down this number or take a clear photo of it. Once you have recorded the number, reinsert the SIM card into the tray, push the tray back into your phone until it clicks, and you are done.

Why you might need your SIM number

Your carrier may ask for your SIM card number when you contact them about account issues, lost SIM replacements, or when switching to a new phone. Some carriers also use it to verify your identity during customer service calls. If you are troubleshooting network problems, your carrier may ask you to confirm your SIM number to rule out SIM-related issues.

Your SIM number is not sensitive information in the way a password is — it is printed on the physical card and visible to anyone who holds it. However, keep a record of it in a safe place so you can provide it quickly if your carrier needs it. Do not confuse your SIM number with your phone number; they are completely different. Your phone number is what people call you, while your SIM number identifies the card itself.

What to do if you cannot find your SIM number

If your phone does not display the ICCID in settings and you cannot remove the SIM card (because it is stuck or your phone is damaged), contact your carrier directly. Call the customer service number on the back of your bill or on your carrier's website. Provide your phone number and account information, and the representative can look up your SIM card number in their system and read it to you.

If you have lost your SIM card or it is damaged, your carrier can issue you a replacement. You will need to provide your account information and phone number, but not the old SIM number. The new card will have a different ICCID, and your carrier will set up it for you. This process usually takes a few minutes over the phone or in person at a carrier store.

Frequently Asked Questions

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

No. Your phone number is what people call you; your SIM card number (ICCID) is a unique identifier for the physical card itself. If you move your SIM to a different phone, your phone number stays the same but the SIM card number does not change. If you get a replacement SIM card, you keep your phone number but get a new SIM card number.

Can I find my SIM number without removing the card?

Yes, if your phone displays it in settings. Go to About Phone (Android) or General > About (iPhone) and look for "ICCID" or "SIM card number". If that field is blank or missing, you will need to remove the card and read the printed number. Some Android phones also display it when you dial *#06#, though not all carriers support this.

What if the number printed on my SIM card is hard to read?

Take a clear photo of the card under good lighting and zoom in on the image. If the printed number is still unclear, contact your carrier with your phone number and account information. They can look up your SIM card number in their system without you having to read it from the card.

Do I need my SIM number to switch carriers?

No. To switch carriers, you need your account number and a transfer PIN from your current carrier. Your SIM number is not required for the switch. However, your new carrier will issue you a new SIM card with a new ICCID when you set up service with them.
