You’re standing in a dimly lit parking lot, or maybe just staring at a Facebook Marketplace listing, wondering if that used iPhone 15 is actually a steal or just a stolen brick. It happens. We’ve all been there, trying to figure out if a device is legitimate before handing over several hundred dollars. To do that, you need the magic 15-digit string. You need to know how to find iPhone IMEI check details without getting scammed by shady websites that look like they haven't been updated since 2005.
The IMEI, or International Mobile Equipment Identity, is basically your phone’s social security number. It is unique. It’s permanent. Unlike a SIM card that you can toss in the trash, the IMEI is hardcoded into the hardware. If a phone is reported stolen, that number goes on a global blacklist. If you buy a blacklisted phone, it’s basically a very expensive paperweight that can’t connect to a cellular network. Honestly, it’s the most important piece of data you own besides your passcode.
The Fastest Ways to Get Your Numbers
Most people think you have to dig through layers of menus, but you really don't. The "old school" way is actually still the best. Open your Phone app. Dial *#06#. You don't even have to press the call button. The screen will just pop up with your IMEI, EID, and Serial Number. It’s instant. It’s universal. It works on basically every iPhone ever made, from the original 2G to the latest Pro Max models.
If the phone won't turn on, you’re in a bit of a pickle, but not totally stuck. On newer iPhones (everything since the iPhone 6s, really), the IMEI is actually etched onto the SIM tray. You’ll need a paperclip or a SIM tool to pop it out. Warning: the text is microscopic. You might need your glasses or a magnifying glass. If you’re looking at an older device like an iPhone 5 or an original SE, check the back casing. It’s printed right there near the bottom. Apple stopped doing this because it messed with the "minimalist aesthetic," which is annoying for us, but that's design for you.
Using the Settings Menu Properly
Maybe you prefer the software route. Go to Settings > General > About. Scroll down. You’ll see "IMEI" listed there. If your phone supports Dual SIM (which most modern ones do), you’ll actually see two IMEIs. Usually, you want the first one, but if you're checking for a carrier lock, both matter.
Sometimes, people get confused between the Serial Number and the IMEI. They aren't the same thing. The Serial Number is for Apple’s internal warranty tracking. The IMEI is for the cellular networks. If you're calling AT&T or Verizon, they don't care about your serial number; they want that 15-digit IMEI.

Why an iPhone IMEI Check Actually Matters
Why bother? Because the secondary market is a minefield. According to data from the CTIA, thousands of devices are blacklisted daily. When you perform an iPhone IMEI check, you’re looking for three specific things:
- Activation Lock status: Is it tied to someone else's iCloud?
- Blacklist status: Is it reported lost or stolen?
- Carrier Lock: Is it tied to T-Mobile forever, or can you use it on any network?
I once helped a friend who bought a "mint condition" iPhone 13. It looked perfect. It turned on. But when he put his SIM card in, nothing happened. We ran the IMEI through a GSMA database, and it turned out the original owner had stopped paying their monthly installments. The carrier flagged the IMEI as "unpaid," which effectively banned the device from the network. It’s a common scam. People get a phone on a payment plan, sell it for cash, and then stop paying the bill. The buyer is the one who gets screwed.
Where to Run the Actual Check
Don't just Google "free IMEI check" and click the first link. A lot of those sites are just data-mining operations trying to get your email. Use official tools whenever possible.
- CTIA Stolen Phone Checker: This is the gold standard for US-based phones. It’s a non-profit site used by the wireless industry.
- Swappa: They have a very reliable, free IMEI checker that checks against global blacklists. It’s tailored for people buying and selling.
- The Carrier’s Own Site: If you think the phone is from Verizon, go to Verizon’s "Bring Your Own Device" page. Type the IMEI in. If they say "This device is not eligible," that’s a massive red flag.
Technical Nuances: The Difference Between IMEI and IMEI2
Modern iPhones (iPhone XR and later) use eSIM technology. This means they have two "slots"—one physical and one digital. Consequently, they have two IMEIs. If you are doing an iPhone IMEI check, it is usually best to check both. Why? Because a phone can actually be "clean" on one IMEI but "blocked" on the second one if it was used for fraudulent activities on a specific line.

It’s rare, but it happens.
Also, keep an eye out for the MEID. This is essentially the IMEI minus the last digit. It was used back when CDMA networks (like the old Sprint and Verizon) were the dominant standard. Nowadays, everything is moving toward GSM/LTE standards, so the 15-digit IMEI is the global language of mobile identity.
Real-World Red Flags to Watch Out For
If you ask a seller for the IMEI so you can run an iPhone IMEI check and they refuse, walk away. Immediately. There is zero legitimate reason to hide an IMEI from a serious buyer. Some sellers claim they’re worried about "cloning," but cloning an IMEI on an iPhone is nearly impossible due to Apple’s Secure Enclave. They’re usually just hiding the fact that the phone is under contract or stolen.

Another weird thing: refurbished phones. If you buy a refurbished unit from a third party, the IMEI might not match the box. This isn't always a scam—sometimes the logic board was replaced during repair—but it does hurt the resale value. Always check that the IMEI in the Settings matches the one on the SIM tray. If they don't match, that phone has been opened up and tinkered with. Maybe it was a high-quality repair, or maybe it was a "Frankenphone" built from three different broken units in a basement.
The Apple Support Profile Trick
Here is a pro tip that most "tech experts" don't even mention. If you already own the device and can't find the box, log into mysupport.apple.com with your Apple ID. Apple lists every device currently signed into your account along with their serial numbers and IMEIs. This is a lifesaver if your phone was actually stolen and you need the IMEI to file a police report or an insurance claim.
You can also find it via iTunes (on PC) or Finder (on Mac). Plug the phone in, click on the "Summary" tab, and then click on your phone number or model name. It will cycle through the ICCID, MEID, and IMEI.
Actionable Next Steps for You
Don't just take a seller's word for it. If you're in the market for a used device or just want to verify your own, follow this sequence:
- Retrieve the code: Use
*#06#to get the digital ID directly from the hardware. - Verify the physical hardware: Ensure the SIM tray etching or the back of the case matches the digital number.
- Check the GSMA Database: Use the CTIA Stolen Phone Checker to ensure it isn't blacklisted.
- Confirm Activation Lock: Go to the iCloud website or try to set the phone up. If it asks for someone else's email, the IMEI check doesn't even matter—the phone is a brick until the previous owner signs out.
- Contact the carrier: If you’re worried about unpaid bills, call the carrier the phone was originally bought from and ask if the device is "financial clear."
Taking ten minutes to run a proper iPhone IMEI check can save you hundreds of dollars and a massive headache. It’s the difference between buying a tool and buying a plastic toy.
Check your own phone today just to have the number written down somewhere safe. If you ever lose it, you'll be glad you have that 15-digit code ready for the authorities and your insurance provider. Keep that info in a password manager or a physical safe—anywhere but just on the phone itself.
