What Is an IMEI and How to Find It

Ever heard the term IMEI number and nodded like you know what it meant? Don’t worry, you’re not alone. Whether you’re switching phone carriers, checking if your mobile device works on a new network, or reporting a stolen device, that little string of digits suddenly becomes very important. 

Let’s break down what an IMEI number is, why it matters, and how to find yours — no tech degree required.

What Is an IMEI Number?

IMEI stands for International Mobile Equipment Identity. It’s a unique, 15-digit serial number used to identify your mobile device. Think of it like a digital fingerprint for your phone. It’s one of a kind and no two devices share the same IMEI number.

Why does this matter? Because phone carriers use IMEIs to track devices, verify their authenticity, and even block access to stolen phones. It’s how networks know who’s legit and who’s up to shady stuff.

What Devices Have IMEI Numbers?

Most modern devices have an IMEI number, including:

• Smartphones

• Tablets with cellular capabilities

• Mobile hotspots
  

• Some smartwatches

Basically, if your device can connect to a mobile network via a SIM card, it likely has a unique IMEI number.

How are IMEI Numbers Used?

IMEI numbers are used by phone carriers for several key reasons, including:

• Activating your device on a network 

• Checking if a phone is compatible with a carrier’s network

• Locking or blacklisting a device if it’s reported lost or stolen

• Tracking or recovering a stolen device with the help of law enforcement
• Verifying a phone’s authenticity, especially in the case of a resale or BYOD

• Scroll down to find your IMEI number

• Or, check the SIM card tray or the original packaging

Android

• Go to Settings → About Phone → IMEI information

• You can also dial *#06# on your dialpad and your IMEI will pop up

Devices With Removable Battery
