What Is an IMEI Number? {#what-is-imei}
An IMEI (International Mobile Equipment Identity) number is a unique 15-digit code assigned to every mobile device in the world. Your phone, tablet, or cellular IoT device carries one or two IMEI numbers embedded permanently in its baseband chipset hardware — they cannot be changed without illegal tampering.
Carriers, governments, and regulators use IMEI numbers to authenticate devices, enforce network blacklists, track stolen phones, and validate SIM activation. When your phone connects to a GSM, LTE, or 5G network, the first thing that happens is your IMEI is checked against a global database.
Understanding your IMEI is the first step in protecting your device. For a deeper breakdown of how this process works across global networks, see our guide on How IMEI Tracking Works in 2026: Networks, Databases, and Location Signals. Following IMEI Security and Privacy Best Practices for 2026 also reduces the risk of your device identifier being exploited.
What Does an IMEI Number Look Like? {#imei-structure}
Every IMEI is exactly 15 digits long and is divided into three parts:
| Segment | Digits | Purpose |
|---|---|---|
| TAC (Type Allocation Code) | 1–8 | Identifies device model and manufacturer |
| Serial Number | 9–14 | Identifies your specific device unit |
| Check Digit | 15 | Validates the IMEI using the Luhn algorithm |
💡 Example:
353045 10 482931 7— TAC35304510(iPhone), Serial482931, Check Digit7.
For a full breakdown of every digit and what it reveals about your device, see our guides on IMEI Number Structure Explained: TAC, Serial Number & Luhn Check Digit (2026) and What Your IMEI Reveals About Your Phone: Complete TAC Decoder Guide (2026).
How to Find Your IMEI Number {#find-imei}
Finding your IMEI takes seconds using any of these methods:
| Method | Steps |
|---|---|
| Dial Code | Dial *#06# on your phone — the IMEI appears instantly on all devices |
| Settings (Android) | Settings → About Phone → Status → IMEI |
| Settings (iPhone) | Settings → General → About → IMEI |
| Device Box | Printed on the retail packaging label |
| Cloud Account | Apple ID → Devices, or Google Account → My Devices |
⚠️ Pro Tip: Write down or screenshot your IMEI before your phone is ever lost or stolen. You won’t be able to dial *#06# on a missing device.

How Does IMEI Tracking Work? {#how-tracking-works}
Every time your phone connects to a mobile network, the carrier reads your IMEI and checks it against GSMA’s global Equipment Identity Register (EIR) or your country’s national CEIR database. This process happens automatically within milliseconds.
If your IMEI is flagged as lost or stolen, the network denies service immediately. If it’s clean, the connection proceeds normally. Carriers also log timestamped location data associated with each IMEI connection — data that law enforcement can access with proper legal authorization.
| Country | Tracking System | Coverage |
|---|---|---|
| 🇮🇳 India | CEIR (ceir.gov.in) | Airtel, Jio, Vi, BSNL |
| 🇺🇸 USA | CTIA Stolen Phone Checker | AT&T, Verizon, T-Mobile |
| 🇦🇺 Australia | AMTA Blacklist | Telstra, Optus, Vodafone |
| 🇨🇦 Canada | CWTA DeviceCheck.ca | Rogers, Bell, Telus |
| 🇬🇧 UK | CheckMEND + carriers | EE, O2, Vodafone, Three |
| 🇿🇦 South Africa | Shared EIR | Vodacom, MTN, Cell C |
| 🇦🇪 UAE | TDRA / Etisalat / du | Mandatory registration |
| 🇵🇰 Pakistan | DIRBS (dirbs.pta.gov.pk) | Jazz, Zong, Telenor, Ufone |

How to Track a Lost Phone Using IMEI {#track-lost-phone}
If your phone is lost or stolen, time matters. Follow these steps immediately:
- Retrieve your IMEI by dialing *#06# before your phone is gone — or check your retail box.
- File a police report and provide the IMEI number as evidence.
- Contact your mobile carrier and request an IMEI blacklist and location trace.
- Use built-in device tools: Google Find My Device (Android) or Apple Find My (iOS).
- Submit a block request to your country’s national IMEI registry — CEIR for India, DIRBS for Pakistan, CTIA for USA, CWTA for Canada, AMTA for Australia.
💡 Don’t have your IMEI? Check your Google Account at myaccount.google.com/device-activity (Android) or your Apple ID at appleid.apple.com (iPhone) — both store your device’s IMEI even after the phone is gone.

How to Check IMEI Before Buying a Used Phone {#check-before-buying}
Buying a second-hand phone without checking the IMEI is one of the most common — and costly — mistakes consumers make. A blacklisted phone cannot connect to any carrier network. A cloned IMEI can cause your phone to be shut down even if it was legitimately purchased.
Always verify these four things before handing over any money:
- Blacklist and stolen status on your country’s official registry
- Carrier lock status (ensure it’s compatible with your network)
- Warranty eligibility with the manufacturer
- That the IMEI shown in Settings matches the device box and SIM tray — if they don’t match, the IMEI has been tampered with
⚠️ Red Flag: If a seller refuses to let you check the IMEI on an official portal before buying, or if the price seems too good to be true — walk away. These are the two clearest signs of a cloned or blacklisted device.

IMEI Blacklisting — What It Means and How It Works {#blacklisting}
IMEI blacklisting is the process by which a carrier or government registry marks a device as lost, stolen, or fraudulent — blocking it from connecting to any participating mobile network. Once blacklisted, the phone can still connect to Wi-Fi but cannot make calls, send SMS, or use mobile data.
ℹ️ Important: A blacklisted IMEI can only be removed by the original carrier or the reporting party upon providing valid proof of ownership. Attempting to unblock or alter an IMEI through third parties is illegal.
If you purchased a used phone that has been blacklisted, contact the carrier with your proof of purchase. Resolution timelines vary by carrier and country, but having clear documentation significantly improves your chances.
Carriers maintain three lists — white, grey, and black — to manage device status across networks.

Is IMEI Tracking Legal? {#legal}
IMEI tracking is legal when performed by authorized carriers and law enforcement with proper authorization. Tracking by private individuals without consent is illegal in virtually every jurisdiction. IMEI alteration is a criminal offence in most countries.
- Carriers track IMEI as part of normal network operations — this is lawful and routine.
- Law enforcement can request carrier data with appropriate warrants or court orders.
- Third-party apps or services claiming to track someone’s IMEI in real-time without permission are either fraudulent or illegal.
- Deliberately altering or cloning an IMEI carries serious criminal penalties in the US, UK, India, and most other countries.

IMEI Scams — How to Protect Yourself {#scams}
IMEI fraud is growing in 2026. Knowing the most common tactics is your best line of defence.
Blacklisted phones with altered IMEIs: Sellers modify or clone IMEIs to pass pre-purchase checks. Always verify on official portals before paying.
Fake IMEI unlock services: Websites that charge fees to “unlock” or “clean” an IMEI are almost always scams. Only the original carrier can legitimately unblock a device.
Police impersonation calls: Callers claim your IMEI is linked to criminal activity — drug trafficking, money laundering — and demand payment to “clear” your record. This is a scam. Real police never call demanding money. Hang up immediately and report to your national cybercrime authority.
Fake IMEI check websites: Sites that harvest your IMEI or personal data under the guise of a “free check.” Always use official government or carrier portals.
Fake IMEI repair shops: Shops that offer to “fix” your IMEI replace your legitimate number with a stolen or duplicated one — making you unknowingly complicit in fraud. Only use authorized service centers.
⚠️ This scam is extremely active in India, Pakistan, and the Philippines. If you receive a call claiming your IMEI is linked to a crime, hang up immediately. Report the number to India’s cybercrime helpline (1930 / cybercrime.gov.in), Pakistan’s NR3C, or the Philippines’ PNP Anti-Cybercrime Group.

Frequently Asked Questions {#faq}
How do I block a stolen phone using its IMEI number?
Contact your mobile carrier immediately, provide your IMEI number (found on your box or by dialing *#06#), and request an IMEI block.

Yes. Police can request location data from carriers using your IMEI. The carrier logs every tower your device connected to. With a court order or formal request, this data is shared with law enforcement.
