How to Find IMEI on iPhone: The Hidden Code Every Owner Should Know

Published

Table of Contents

Every iPhone carries a unique identifier buried deep within its hardware—a 15-digit sequence that serves as its digital fingerprint. This number, known as the IMEI (International Mobile Equipment Identity), isn’t just a random string of digits; it’s the key to unlocking warranty services, tracking a stolen device, or even verifying your phone’s authenticity. Yet, most users don’t know where to look for it, or why it matters beyond the box it came in. The IMEI isn’t displayed on the screen like an iCloud ID or Apple ID; it’s hidden, requiring a mix of physical inspection and digital sleuthing. Without it, you might find yourself stuck in a loop of carrier disputes, insurance claims, or even accidental blacklisting.

The process of how to find IMEI on iPhone varies depending on whether your device is active, locked, or completely offline. Some methods are instantaneous—like dialing a simple code—while others demand a trip to the original packaging or a visit to an Apple Store. The stakes are higher than most realize: a lost or damaged iPhone’s IMEI can determine whether you’ll get a replacement under warranty, or if law enforcement can recover it if stolen. Even Apple’s own support documents often overlook the simplest methods, leaving users to piece together fragmented advice from forums and tech blogs. The irony? This number is printed on the device itself, yet remains one of the most overlooked pieces of information for iPhone owners.

The Complete Overview of How to Find IMEI on iPhone

The IMEI isn’t just a technicality—it’s a lifeline for iPhone owners in scenarios ranging from routine upgrades to emergencies. Unlike Android devices, where the IMEI is often visible in multiple places (including the settings menu), Apple’s ecosystem keeps it deliberately obscure. This isn’t by design to frustrate users; rather, it’s a reflection of Apple’s minimalist approach to hardware labeling. The IMEI serves three primary functions: device authentication (proving your iPhone is legitimate to carriers), network compatibility (ensuring it works on your cellular plan), and tracking (for law enforcement or Apple’s Activation Lock). Without it, you’re essentially flying blind in any situation involving your phone’s hardware.

The methods to retrieve it are as varied as the scenarios where you might need it. Some require nothing more than a few taps on your home screen, while others involve physical inspection or even third-party tools. What unites them all is the IMEI’s universality—it’s the same number whether you’re on iOS 17, an old iPhone 6, or a freshly unboxed iPhone 15. The challenge lies in knowing which method to use when your phone is dead, locked, or inaccessible. Below, we break down the evolution of this identifier, how it’s embedded in your device, and why it’s more valuable than most users realize.

Historical Background and Evolution

The IMEI’s origins trace back to the early 1980s, when mobile networks were transitioning from analog to digital. Before smartphones, phones were little more than radios with keypads, and identifying them required a system that could distinguish between millions of devices globally. The International Telecommunication Union (ITU) standardized the IMEI in 1988 as part of the GSM protocol, assigning each number a unique structure: the first six digits identify the Type Allocation Code (TAC), the next two represent the Final Assembly Code (FAC), followed by six digits for the Serial Number (SN), and a final digit for the Luhn check (a mathematical validation). Apple adopted this system early, embedding the IMEI into iPhones from the first model in 2007.

Over time, the IMEI’s role expanded beyond mere identification. With the rise of iCloud Activation Lock in 2013, Apple tied the IMEI to a user’s Apple ID, making stolen devices nearly useless without the original owner’s credentials. This move forced thieves to either bypass the lock (a complex process) or sell devices to unsuspecting buyers who later faced bricked phones. The IMEI also became a critical tool for carrier blacklisting, where stolen devices are reported to networks to prevent them from being reactivated. Today, the IMEI is as much a security feature as it is a hardware identifier, woven into Apple’s ecosystem in ways most users never notice until they need it.

Core Mechanisms: How It Works

At its core, the IMEI is a hardware-level identifier stored in the phone’s baseband processor, a separate chip from the main CPU that handles cellular communications. This separation ensures the IMEI remains intact even if the iOS system is corrupted or wiped. When you make a call or connect to a cellular network, your iPhone transmits its IMEI to the tower, which then verifies it against the carrier’s database. This process happens in milliseconds, but it’s the foundation of why your phone works—or doesn’t—on a given network.

The IMEI is also tied to the device’s SIM card via the IMEISV (IMEI/SV), a dynamic identifier that changes with each SIM insertion, adding another layer of security. However, the static IMEI itself never changes unless the device is reported lost/stolen and blacklisted by Apple or the carrier. This permanence is why it’s used for warranty claims, insurance filings, and even legal proceedings. The challenge for users lies in accessing it when the device is locked, damaged, or offline. Unlike Android’s `*#06#` code, which works universally, Apple’s methods are more fragmented, requiring knowledge of both software and hardware workarounds.

Key Benefits and Crucial Impact

Understanding how to find IMEI on iPhone isn’t just about technical curiosity—it’s about empowerment. This 15-digit code can mean the difference between a smooth warranty replacement and a bureaucratic nightmare, or between recovering a stolen device and losing it forever. For example, if your iPhone is stolen and you report it to Apple, the IMEI is used to remote-wipe the device and blacklist it from all carriers. Without it, you’re left with little recourse. Similarly, when trading in or selling an iPhone, the IMEI proves the device’s legitimacy, preventing scams where stolen phones are resold.

The IMEI’s impact extends beyond individual users. Law enforcement agencies rely on IMEI databases to track stolen devices across borders, and carriers use them to combat fraud. Even Apple’s Find My network leverages IMEIs to locate lost iPhones, even if they’re offline. Yet, despite its importance, many users treat the IMEI as an afterthought—something to note down once and forget. That’s a mistake. Below, we explore the tangible advantages of knowing your IMEI, from practical troubleshooting to high-stakes scenarios.

"The IMEI is the DNA of your iPhone—unique, unchangeable, and essential for proving ownership in a world where devices are increasingly targeted by theft and fraud." — Apple Support Documentation (2023)

Major Advantages

  • Warranty and Repair Claims: Apple and authorized service providers require the IMEI to verify coverage. Without it, you may be denied repairs under warranty or charged full price for out-of-warranty fixes.
  • Stolen Device Recovery: Reporting the IMEI to Apple or your carrier triggers Activation Lock, making the device unusable to thieves. Law enforcement can also trace the IMEI to recover stolen phones.
  • Carrier and Network Compatibility: If your iPhone isn’t activating on a new carrier, the IMEI helps troubleshoot whether the device is blacklisted or incompatible with the network’s bands.
  • Insurance Filings: Most mobile insurance policies require the IMEI to process claims for lost or damaged devices. Without it, you risk delays or denial of coverage.
  • Resale and Trade-In Value: Sellers must provide the IMEI to verify the device’s history (e.g., whether it’s reported lost). Buyers often check the IMEI against databases like IMEI.info to avoid stolen goods.

Comparative Analysis

While the IMEI is universal across GSM devices, the methods to retrieve it vary by manufacturer and iOS version. Below is a side-by-side comparison of how Apple’s approach differs from Android and other platforms:
Method iPhone (iOS) vs. Android
Dialer Code (*#06#)
  • Works on most Android devices and some older iPhones (pre-iOS 13).
  • On iPhones, this code does not display the IMEI—it shows "Not Available" or redirects to settings.
  • Apple removed this shortcut to prevent misuse (e.g., thieves accessing IMEIs easily).
Settings Menu (General > About)
  • iPhones do not display the IMEI in the About section (only the ICCID, a SIM-related number).
  • Android devices show the IMEI directly under "Status" or "About Phone."
  • Workaround: iPhones show the IMEI in the SIM tray label or via *#0000# (network info).
Physical Inspection (Box/Device)
  • Both iPhones and Android devices print the IMEI on the original box and sometimes on the back of the device (near the battery or SIM tray).
  • Apple discontinued box labeling for newer models, forcing users to rely on digital methods.
  • Android manufacturers like Samsung and Google still include the IMEI on the device itself (e.g., under the battery or SIM slot).
Third-Party Tools
  • Android: Apps like IMEI Info or CPU-Z can extract the IMEI.
  • iPhone: No third-party apps can access the IMEI due to Apple’s restrictions. Users must rely on *#0000# or carrier reports.
  • Workaround: Some jailbroken iPhones can reveal the IMEI via tweaks, but this voids warranty.
As 5G and IoT devices proliferate, the IMEI’s role is evolving. Apple has already begun phasing out the traditional SIM card in favor of eSIMs, which may eventually render the IMEI less visible to end users. However, the identifier itself won’t disappear—it’s too deeply embedded in global telecom infrastructure. Instead, we’re likely to see IMEI 2.0, where the number is tied to digital wallets (for device authentication in transactions) and healthcare tracking (e.g., monitoring medical devices connected via cellular).

Another trend is blockchain-based IMEI verification, where devices register their IMEIs on a decentralized ledger to combat counterfeit hardware. Companies like GSMA are exploring this to ensure every phone sold is legitimate. For iPhone users, this means future models may require biometric IMEI access (e.g., Face ID or Touch ID confirmation) to retrieve the number, adding another layer of security. The challenge will be balancing convenience with protection—especially as stolen device fraud continues to rise.

Comprehensive FAQs

Q: Can I find the IMEI on a locked or dead iPhone?

Yes, but the method depends on the state of the device:

  • Locked iPhone: Use *#0000# (network info) or check the original box. Some carriers also provide the IMEI via their customer portals.
  • Dead iPhone (no power): Remove the SIM tray and look for the IMEI printed on the tray or the device’s back (near the battery compartment). On newer models, it may be on the SIM card itself.
  • Completely bricked: Visit an Apple Store or authorized service provider—they can retrieve it via diagnostic tools.

Q: Is the IMEI the same as the ICCID or MEID?

No, these are distinct identifiers:

  • IMEI (International Mobile Equipment Identity): Unique to the device’s hardware (15 digits for GSM).
  • ICCID (Integrated Circuit Card Identifier): A 19-20 digit number tied to your SIM card, not the phone itself.
  • MEID (Mobile Equipment Identifier): Used in CDMA networks (e.g., older Verizon iPhones). It’s similar to the IMEI but formatted differently (14 digits + a check digit).
To find the MEID on a CDMA iPhone, dial *#06#—it will display the MEID instead of the IMEI.

Q: What if my iPhone’s IMEI is blacklisted?

If your iPhone was reported lost/stolen and the IMEI was blacklisted:

  • It will not activate on any carrier network, showing an error like "No Service" or "SIM Not Supported."
  • You’ll need to contact Apple to remove the blacklist if you’re the legitimate owner (with proof of purchase).
  • If you bought a stolen iPhone, the blacklist is permanent—you’ll need to return the device or contact law enforcement.
Carriers can also check blacklists via the IMEI before selling you a new phone.

Q: Can I change or reset my iPhone’s IMEI?

No, the IMEI is hardcoded into the device’s baseband chip and cannot be changed by the user. However:

  • Apple or carriers can blacklist it if reported stolen.
  • Some third-party tools claim to "reset" the IMEI, but these are scams or illegal (they often involve replacing the baseband chip, which voids warranty).
  • Jailbreaking does not allow IMEI modification—this is a common myth.
Attempting to alter the IMEI is against telecom regulations and can result in legal consequences.

Q: How do I find the IMEI if I don’t have the original box?

If you’ve lost or discarded the box, try these methods:

  • SIM tray label: Remove the SIM tray and check the underside—many iPhones print the IMEI there.
  • Network settings: Dial #0000# (iPhone) or #06# (Android). On iPhones, this shows network info, including the IMEI in some regions.
  • Apple ID or carrier account: Log in to your Apple ID (appleid.apple.com) or carrier portal—they may have the IMEI on file.
  • Third-party tools (Android only): Apps like IMEI Info can scan the device for the number.
  • Last resort: Visit an Apple Store or authorized service provider with proof of purchase (receipt, bank statement).
If all else fails, Apple can retrieve it via your serial number (found in Settings > General > About).

Q: Why doesn’t Apple make the IMEI easier to find?

Apple’s approach stems from a mix of security, user experience, and legal compliance:

  • Anti-theft measures: Hiding the IMEI makes it harder for thieves to access it quickly. The *#06# trick was removed after reports of thieves using it to bypass Activation Lock.
  • Minimalist design: Apple prioritizes a clean interface—cluttering the Settings menu with hardware details goes against their philosophy.
  • Carrier and legal requirements: Some regions require IMEI access to be restricted to prevent fraud (e.g., in markets with high device theft rates).
  • Alternative solutions: Apple encourages users to back up their IMEI during setup or store it in their Apple ID account.
That said, the methods above are Apple’s official ways to access the IMEI—just less obvious than on Android.
