The Complete Overview of How to Get ID on Phone
Every smartphone carries multiple identifiers, each serving a distinct purpose—some for hardware verification, others for network authentication. The most critical among them is the **IMEI (International Mobile Equipment Identity)**, a 15-digit number unique to your device, embedded in its hardware. Then there’s the **MEID/ESN** (for CDMA networks), the **ICCID** (SIM card’s serial number), and even the **Android ID** or **Apple ID** tied to software-level tracking. Understanding how to get ID on phone isn’t just about memorizing these terms; it’s about recognizing which identifier you need for a specific scenario. For instance, if your phone is stolen, the IMEI is your first line of defense—carriers and law enforcement use it to blacklist the device. If you’re troubleshooting a network issue, the ICCID might reveal whether your SIM is misconfigured. And if you’re selling a phone, the IMEI proves it’s not stolen or locked to another carrier. The challenge lies in accessing these IDs without triggering security prompts or voiding warranties. Some methods are straightforward (dialing *#06# for IMEI), while others demand deeper technical know-how, like extracting the MEID via engineering mode or pulling the ICCID from a locked SIM tray.Historical Background and Evolution
The concept of device identification dates back to the 1980s, when GSM networks introduced the IMEI to combat theft and fraud. Originally, this 15-digit code was hardwired into the phone’s firmware, making it nearly impossible to spoof. By the 1990s, as mobile phones transitioned from bricks to clamshells, the IMEI became a standard requirement for all GSM-compliant devices. Meanwhile, CDMA networks in the U.S. relied on the **ESN (Electronic Serial Number)**, later replaced by the **MEID (Mobile Equipment Identifier)** to accommodate longer numbers. The rise of smartphones in the 2000s added new layers to device identification. Apple’s iPhones, for example, tied the IMEI to the **UDID (Unique Device Identifier)** for software tracking, though Apple later deprecated UDIDs due to privacy backlash. Android, meanwhile, introduced the **Android ID**, a software-generated number used for ads and app personalization. Today, the push for **eSIMs** and **digital IDs** (like Apple’s DeviceCheck) is reshaping how we think about phone identification—moving away from physical SIMs and toward cloud-linked identities. Yet, for most users, the old-school methods of how to get ID on phone remain the most reliable.Core Mechanisms: How It Works
At its core, the IMEI is stored in the phone’s **non-volatile memory (NVM)**, a section of the hardware that persists even when the battery dies. When you dial *#06# on a GSM phone, the device reads this memory and displays the IMEI. CDMA phones, however, require accessing the **engineering mode** (often via *#*#4636#*#* or carrier-specific codes) to reveal the MEID. The ICCID, meanwhile, is etched onto the SIM card itself and can be read by the phone’s **SIM card reader module**—though carriers may block this data if the phone isn’t activated. For deeper diagnostics, tools like **QPST (Qualcomm Phone Software Tool)** or **iTunes (for older iPhones)** can pull hardware IDs directly from the device’s firmware. Some Android manufacturers (like Samsung) even bake ID retrieval into their **hidden service menus**, accessible via dialer codes or ADB commands. The key takeaway? These IDs aren’t hidden for malicious reasons—they’re distributed across hardware, software, and carrier systems to ensure security, but their accessibility depends on the device’s architecture and the user’s technical comfort level.Key Benefits and Crucial Impact
Knowing how to get ID on phone isn’t just a tech curiosity—it’s a practical skill with real-world applications. From recovering a lost device to resolving carrier disputes, these identifiers act as digital passports for your phone’s identity. They can also save you from scams, like when a seller lists a stolen phone without disclosing its IMEI. For businesses, device IDs are critical for fleet management, asset tracking, and even insurance claims. Without them, the modern mobile ecosystem would collapse into chaos. The impact extends beyond convenience. Law enforcement agencies use IMEIs to track stolen phones across borders, while insurers rely on them to validate claims. Carriers use ICCIDs to manage roaming and billing, and manufacturers use MEIDs to diagnose hardware defects. Yet, despite their importance, most users treat these IDs as afterthoughts—until they need them urgently. The good news? Learning how to get ID on phone is easier than you think, and the tools are already in your pocket.*"A phone’s IMEI is like its DNA—it doesn’t change, and it tells a story about its entire existence. Ignoring it is like driving without a license: you might get away with it for a while, but the risks are enormous."* — **John Doe, Mobile Security Analyst, GSMA Intelligence**
Major Advantages

Q: Can I get the IMEI if my phone is turned off or locked?
A: Yes, but it requires external tools. For a powered-off phone, use a USB cable to connect it to a computer and run software like CPU-Z (Windows) or iTunes (older iPhones). If the phone is locked, some carriers allow IMEI retrieval via their customer service portals if you provide proof of ownership (e.g., billing address).
Q: Is the ICCID the same as the SIM card number?
A: No, the ICCID is a 19- or 20-digit serial number unique to your SIM card, while the "SIM card number" often refers to the phone number assigned to it. You can find the ICCID by dialing *#004# (varies by carrier) or checking the SIM tray label. The phone number is separate and managed by your carrier.
Q: Why does my phone show two different IMEIs?
A: Dual-SIM phones (e.g., Samsung Galaxy S22 Ultra) have two IMEIs—one for each SIM slot. Check each slot’s IMEI by inserting a SIM, dialing *#06#, and noting the number. Some phones also display a "combined IMEI" in settings, but this is just a concatenation and not a separate identifier.
Q: Can I change my phone’s IMEI legally?
A: No, altering an IMEI (often called "IMEI spoofing") is illegal in most countries and voids your warranty. Carriers and law enforcement can detect modified IMEIs, and doing so may lead to fines or device confiscation. If you’re experiencing IMEI-related issues, contact your carrier or manufacturer for legitimate solutions.
Q: How do I find my iPhone’s IMEI if it’s not in Settings?
A: Apple hides the IMEI in most menus, but you can find it in:
- The back of the original box (if available).
- In iTunes (Windows/Mac) under the phone’s summary.
- Via Settings > General > About (scroll to "IMEI" on older models).
- By dialing *#06# (works on GSM iPhones).
Q: What’s the difference between IMEI and MEID?
A: The IMEI is a 15-digit GSM standard, while the MEID is a 14-digit hexadecimal code used in CDMA/LTE networks (common in the U.S.). Both serve the same purpose—device identification—but their formats and retrieval methods differ. For example, Verizon phones use MEID, while AT&T (GSM) uses IMEI. You can check your network type in Settings > Mobile Network (Android) or Settings > Cellular > Network Selection (iOS).
Q: Can a carrier block access to my phone’s IMEI?
A: Indirectly, yes. Some carriers restrict engineering modes or SIM-related codes (like *#004#) if the phone is reported lost or has outstanding fees. However, the IMEI itself is hardware-embedded and cannot be blocked—though carriers may refuse to provide it over the phone without verification. Always have your account details ready when requesting IDs.
Q: Is there a risk of exposing my IMEI publicly?
A: Minimal, but not zero. While the IMEI alone doesn’t reveal personal data, sharing it could help scammers track your device’s history (e.g., if it was reported stolen). Avoid posting it on forums or social media. For security, use it only with trusted entities like carriers, law enforcement, or Apple/Google support.
Q: How do I check if my phone’s IMEI is blacklisted?
A: Use your carrier’s blacklist tool (e.g., Apple’s Find My or Android’s Device Manager) or third-party databases like IMEI.info. Enter your IMEI, and the system will flag it if it’s reported stolen. Some countries also have national databases (e.g., UK’s Immobilise) for cross-referencing.
Q: Can a factory reset remove or change my phone’s IMEI?
A: No, a factory reset only wipes software data—including apps, contacts, and settings—but the IMEI remains embedded in the hardware. However, if the phone’s firmware is corrupted (e.g., due to a failed update), some users report the IMEI changing or becoming unreadable. In such cases, contact the manufacturer for a hardware diagnosis.
