If you’ve bought, sold, or reported a lost phone, you’ve likely encountered the term “IMEI number” before. But what exactly does it mean? Let’s delve into it.
Deciphering the IMEI Number
The IMEI number, short for International Mobile Station Equipment Identity, serves as a unique 15 or 16-digit identifier for mobile devices equipped with GSM, UMTS, or LTE modems. This number provides crucial details such as the device’s origin, model, and serial number. The initial 8 digits indicate origin and model, while the remaining digits are manufacturer-assigned.
IMEI attaches to the modem in the device. If a mobile phone has dual SIM functionality, it will have two unique IMEI numbers for the dual modems. Besides IMEI numbers, other identity standards for mobile devices include ESN and MEID. Let’s examine their differences:
Distinguishing IMEI, MEID, and ESN
IMEI, MEID (Mobile Equipment Identifier), and ESN (Electronic Serial Number) all serve as device identifiers. ESN has become obsolete, with its last assignment in 2010. ESNs were previously used with AMPS and TDMA devices, occasionally with CDMA devices.
Regarding MEID, it was designed as a superset to IMEI and a replacement for ESN. MEID and IMEI serve similar purposes, with MEID consisting of a hexadecimal 14-digit format. However, MEID primarily serves CDMA modem devices, while IMEI is for GSM devices.
Various Methods to Find IMEI
Using USSD Code
Typing *#06# displays the IMEI number on all feature phones and smartphones. Simply input the USSD code into the dialer to retrieve the IMEI number. Note that this method does not function on Windows Phone devices.
In Phone Settings
All platforms display your device’s IMEI number in Settings. On Android, find it in Settings->About phone->Status->IMEI information. On iPhone, locate it in Settings->General->About, and on Windows Phone, find it in Settings->About.
On the Phone’s back or Battery
Retail box or Bill
Using Google Dashboard (Android only)
For Android smartphones, check your device’s IMEI number online at the Google Dashboard. Simply log in with your Google account and access the Android section to view all connected devices and their IMEI numbers.
Using iTunes (iOS only)
Check your iPhone’s IMEI using iTunes on your computer. Connect your iPhone, open iTunes, and select your device. Then, go to “Summary” and click on phone number to view the device’s MEID and IMEI number.
Using Microsoft account (Windows Phone only)
To check your Windows Phone or Mobile’s IMEI number, visit Microsoft account, and log in with the connected account. Click on “Devices” and select the device to find its IMEI number.
How is IMEI useful?
Repair
Imagine sending your mobile device for repair only to have it return bricked and lifeless. How do you discern if the returned device is indeed yours or another? The answer lies in the IMEI number.
Buying a Pre-owned Device
Tracking a Lost/Stolen Phone
Warranty Verification
Upon initial setup of your new mobile phone, its IMEI number activates alongside the date. Consequently, even without the bill, your purchase date remains linked to your device’s IMEI. Thus, facilitating warranty claims.
Understanding the Significance of IMEI Numbers
IMEI numbers, though seemingly just another technical specification of a mobile phone, serve various purposes. It’s crucial to note down your device’s IMEI number, as it can prove useful unexpectedly.
