The IMEI is printed on your iPhone's physical SIM tray and visible in Settings

Your iPhone's IMEI (International Mobile Equipment Identity) is a 15-digit number that identifies your specific device to cellular networks. You can find it three ways: by looking at the SIM tray that came out of your phone, by checking the Settings app, or by dialing a code on the keypad. The SIM tray method is fastest if your phone is in front of you right now.

The IMEI matters when you're switching carriers, filing a theft report, checking warranty status, or troubleshooting network problems with your provider. Different carriers and Apple support may ask for it, so knowing where to find it saves time when you need it.

Key Takeaways

  • The IMEI is printed on the SIM tray that slides out of your iPhone's side — you can read it without opening Settings.
  • You can also find your IMEI in Settings by going to General, then About, and scrolling to the IMEI field.
  • Dialing *#06# on your iPhone's keypad displays the IMEI on screen when ready.
  • Your IMEI is different from your phone number, SIM card number, or serial number — each one identifies something different.
  • Keep your IMEI handy if you plan to report your phone stolen or switch to a new carrier.

Finding the IMEI on the SIM tray

The fastest way to find your IMEI is to look at the SIM tray itself. On the side of your iPhone (the location varies by model — iPhone 14 and newer have it on the right side, older models may have it on the left), there is a small slot with a pinhole. Use the SIM ejector tool that came in your iPhone box, or a straightened paperclip, to gently press the hole until the tray pops out.

Once the tray is out, look at the metal part that holds the SIM card. The IMEI is printed directly on the tray in small text. It is a 15-digit number. Write it down or take a photo if you need to keep it. Slide the tray back in until it clicks — it only goes in one way, so you cannot force it wrong.

Finding the IMEI in the Settings app

If you do not have the SIM ejector tool or prefer not to remove the tray, open the Settings app on your iPhone. Tap General, then scroll down and tap About. Scroll through the list until you see the field labeled IMEI. The 15-digit number appears there.

From the About screen, you can also copy the IMEI by pressing and holding on the number, then tapping Copy. This is useful if you need to paste it into a form or email to your carrier. The About screen also shows your serial number, phone number, and other device details in one place.

Using the dial code to display your IMEI

On any iPhone, you can dial a code to see your IMEI without opening Settings. Open the Phone app and go to the Keypad tab. Dial *#06# and press the call button. Your IMEI appears on screen when ready — you do not actually make a call.

This method works on any carrier and does not require a SIM card to be in the phone. It is the quickest option if your phone is unlocked and you are already holding it, but the number disappears when you hang up, so take a screenshot or write it down if you need to keep it.

What the IMEI is used for

Your carrier uses the IMEI to connect your phone to their network. If you switch carriers, the new carrier may ask for it to set up service on their SIM card. If your iPhone is stolen, you can give the IMEI to police and your carrier — they can block the device from connecting to any network, making it useless to a thief even if they erase it.

Apple uses the IMEI to look up your device's warranty status and repair history. If you contact Apple Support, they may ask for it to pull up your account. Some third-party repair shops also ask for the IMEI to verify the device is not reported stolen before they work on it.

IMEI versus serial number, phone number, and SIM card number

These four numbers all appear in your phone's settings, and they are straightforward to confuse. Your IMEI identifies the phone hardware itself. Your serial number (also called the SEID on newer iPhones) is another unique identifier for the same device — Apple uses it for warranty and repair. Your phone number is assigned by your carrier and can change if you switch carriers or plans. Your SIM card number (the ICCID) identifies the SIM card, not the phone — if you swap SIM cards, this number changes but your IMEI stays the same.

When a company asks for your IMEI, they want the 15-digit number, not the serial number or phone number. If you are unsure which one they need, ask them to clarify — they may say "the IMEI" or "the device identifier" or "the 15-digit number."

What to do if you cannot find your IMEI

If your iPhone is damaged and the SIM tray is stuck, or if you have lost the phone but need the IMEI for a theft report, contact your carrier. They have your IMEI on file because it is linked to your account. Call their customer service number (usually on your bill or their website) and ask them to provide your device's IMEI. You will need to verify your account by answering security questions or providing your account number.

If you bought your iPhone from Apple, you can also contact Apple Support with your proof of purchase. They can look up the IMEI from your order. If the phone is still under warranty, Apple's records include the IMEI from the moment you activated it.

Frequently Asked Questions

Can someone use my IMEI to steal my phone?

Not directly. The IMEI alone does not unlock your phone or access your data. However, if someone has both your IMEI and your SIM card, they could potentially set up service on a different phone using your number. This is why reporting your IMEI to your carrier when ready after theft is important — they can block it from their network.

Does my IMEI change if I update iOS?

No. Your IMEI is tied to the phone's hardware and never changes, even if you update the operating system, restore the phone, or erase all data. It stays the same for the life of the device.

What if the IMEI on my SIM tray does not match the one in Settings?

This should not happen on a genuine iPhone. If the numbers do not match, your phone may be counterfeit or heavily damaged. Contact Apple Support or your carrier with both numbers and explain the discrepancy. They can help you determine whether the device is authentic.

Do I need my IMEI to sell my iPhone?

Most buyers do not ask for the IMEI, but some do — especially if they are buying from a distance. Having it available speeds up the sale. You can provide it to the buyer so they can verify the phone is not reported stolen before they complete the purchase.
