What an IMEI number is and why you need it

Your Samsung phone's IMEI (International Mobile Equipment Identity) is a 15-digit code that uniquely identifies your device on cellular networks worldwide. Think of it as a serial number for your phone's connection to carriers like Verizon, AT&T, or T-Mobile.

You'll need this number if you're switching carriers, filing an insurance claim, reporting a stolen phone to your carrier, or troubleshooting network problems with Samsung support. Some carriers also use it to unlock your phone or verify you own the device before making account changes.

Key Takeaways

  • Your IMEI appears on the original box your Samsung came in, on your carrier's account page, and in your phone's settings under About Phone.
  • Dialing *#06# on your Samsung's keypad displays the IMEI when ready without opening any menus.
  • If your phone won't turn on, check the original packaging, your carrier's records, or contact Samsung with your phone's serial number.
  • Write down your IMEI and store it somewhere safe in case you need it for insurance, carrier support, or theft reporting.

Finding your IMEI by dialing a code

The fastest way to see your IMEI is to open your Samsung's phone dialer and type *#06#, then press call. Your IMEI will appear on the screen when ready—you don't need to actually make a call. This works on any Samsung phone with a SIM card.

Write down all 15 digits carefully. If you're having trouble reading the screen, take a screenshot by pressing the power button and volume-down button at the same time, then zoom in on the image to verify each digit.

Checking your IMEI in phone settings

Open Settings on your Samsung, then tap About Phone (the exact wording varies slightly by model—it might say "Device Information" or "Phone Information"). Scroll down until you see IMEI or IMEI 1 and IMEI 2 if your phone has two SIM slots. The number will be displayed in full.

Dual-SIM Samsung phones show two separate IMEI numbers—one for each SIM card slot. If you're switching carriers or reporting a problem, make sure you're using the correct IMEI for the SIM you're actually using. IMEI 1 is typically the primary slot.

Finding your IMEI on the original packaging and documents

Check the box your Samsung came in. The IMEI is usually printed on a sticker on the back or inside the box, often near the barcode. If you kept your receipt or paperwork from your carrier, the IMEI may also be listed there.

If you bought the phone secondhand and don't have the original box, your carrier can look up the IMEI using your phone number and account information. Call their customer service line and explain that you need your device's IMEI for support or verification purposes.

Checking your IMEI through your carrier's account

Log into your carrier's website or app—Verizon, AT&T, T-Mobile, and most regional carriers display device information in your account settings. Look for a section labeled "My Devices," "Device Information," or "Account Details." The IMEI will be listed there alongside your phone number and plan information.

This method is especially useful if your phone is damaged or won't power on. You can retrieve your IMEI from any computer or another device without touching your Samsung at all. If you can't find it online, call your carrier's customer service and they'll read it to you over the phone.

What to do if your phone won't turn on

If your Samsung is completely unresponsive, start with the original box and packaging—the IMEI is printed there and doesn't require the phone to be powered. Next, contact your carrier directly and provide your phone number and account details; they can pull up your device's IMEI from their records in seconds.

You can also reach out to Samsung support with your phone's serial number (different from the IMEI, but also printed on the box and in settings). Samsung can cross-reference the serial number to provide your IMEI. Have your proof of purchase ready, as some support agents ask for it before releasing device information.

Protecting your IMEI information

Your IMEI is not a secret like a password, but it is tied to your device. Write it down and store it in a safe place—a notes app, a document in your email, or a physical notebook. If your phone is stolen, you'll need this number to report it to your carrier and potentially to law enforcement.

Do not share your IMEI with unknown websites or people claiming to offer unlocking services, carrier switching help, or device verification. Legitimate carriers and Samsung support will never ask you to provide your IMEI through email or unsecured messaging. If someone requests it unsolicited, it's a sign of a scam.

Frequently Asked Questions

Can I find my IMEI if I don't have the original box?

Yes. Dial *#06# on your phone, check Settings > About Phone, or log into your carrier's account online. If your phone won't turn on, contact your carrier with your phone number and they'll retrieve it from their system.

What's the difference between IMEI and serial number?

Your IMEI is a 15-digit network identifier, while your serial number is a unique manufacturing code. Both appear on your box and in settings. Carriers use the IMEI; Samsung uses the serial number for warranty and support purposes.

Do I need both IMEI numbers if my Samsung has two SIM slots?

Only if you're using both SIM cards actively. If you're switching carriers or reporting a problem with one line, use the IMEI for that specific slot. Your carrier can tell you which IMEI corresponds to which SIM position.

Is my IMEI the same as my phone number?

No. Your phone number is assigned by your carrier and can change if you switch carriers. Your IMEI is permanently tied to your physical device and never changes, even if you get a new SIM card or phone number.

What should I do if someone asks for my IMEI online?

Only provide your IMEI to your actual carrier's official website or app, or to Samsung support through their verified channels. Never share it with third-party unlocking services, resellers, or people contacting you unsolicited. Legitimate companies will never ask for it via email or text.
