The IMEI acronym stands for International Mobile Equipment Identity. Every mobile phone has a special identification number that is assigned to it, you can usually find it on the package or behind the battery. The IMEI number is used to identify legitimate mobile devices on a network and can be used to prevent a device from using that network if it has been reported lost or stolen.
An IMEI number is 15 digits long and is broken up into numerous parts. The last digit is a check digit used to verify the validity of the whole IMEI, while the first 14 digits constitute the unique identifying number. When a device is reported lost or stolen, its IMEI number can be used to monitor it and prohibit it from being used on a network.
The IMEI number can also be used to pinpoint a device's particular characteristics and functionalities. It can be used, for instance, to identify the device's kind, maker, and model. The IMEI number can also be used to check a device's warranty status and determine whether it has been serviced or replaced.
Who Invented IMEI Number ?
The GSM Association (GSMA), an industry trade organisation that represents the interests of mobile network operators worldwide, created the IMEI (International Mobile Equipment Identity), a unique number provided to every mobile phone. In 1996, the first IMEI was released.
How do IMEI Number Work ?
The special 15-digit number is given to each mobile device as soon as the mobile phone is manufactured.
The TAC (Type Allocation Code), the SNR (Serial Number), and the CD are some of the components that make up the IMEI (Check Digit). The device's manufacturer and model are identified by the TAC, which is the first six digits of the IMEI. For instance, the TAC for an iPhone 6s would differ from the TAC for a Samsung Galaxy S8.
The SNR, which follows the IMEI by 6 numbers, designates a distinct device within a given model. Two iPhone 6s units, for instance, can have the same TAC but different SNRs.
The IMEI's 15th digit, known as the CD, is used to confirm the IMEI's validity. It is calculated using a mathematical formula that considers all the IMEI's additional digits.
The network will check the IMEI of a connected mobile device against a list of IMEIs that are permitted to be used on that network. The device won't be able to connect to the network if the IMEI cannot be located in the database. This procedure, called as an IMEI check, is carried out to stop the usage of stolen or fake devices on the network.
Additionally, if a device is reported as stolen or lost, its IMEI can be used to blacklist it. When a device is placed on a blacklist, its IMEI is added to a list of IMEIs that cannot be used on any network. When a device with a blacklisted IMEI tries to connect to a network, the connection is denied. This is carried out to stop the usage of stolen equipment on any network.
How to Find your IMEI Number ?
To locate a device's IMEI number, use one of the following methods:
On the Mobile Phone: Look for a label with the IMEI number on the phone itself, either on the back or in the battery compartment. It might even be written on the box the phone was delivered in.
Dialing a code: In order to see the IMEI number on the screen on most phones, you can dial *#06#.
Check the settings: Look for a section called "About phone" or "Device information" in the settings menu. This field must contain the IMEI number.
Check the SIM tray: The IMEI number is printed on the SIM tray on some smartphones.
Check the original Bill: The IMEI number is typically listed on the bill if you still have the original packaging for the phone and the bill.
It's important to keep in mind that some of the aforementioned techniques could not function for all devices, depending on the maker or software version.
What are the Uses of IMEI Number ?
Device Identification
On a mobile network, IMEI is used to identify a particular device in a unique way. Because of this, every mobile device has a special IMEI number that may be used to identify it on a network. When a gadget is lost or stolen, this can be used to trace it down and assist in its recovery.
Network Access
A functioning IMEI is required for mobile devices to connect to a mobile network. The IMEI is used by the network operator to confirm that the device has permission to use its network. A device with a blacklisted IMEI cannot connect to the network as a result.
Blacklisting
A device's IMEI may be blacklisted by the network operator if it is reported lost or stolen. As a result, the device is unable to connect to the network, which can help stop a stolen device from being used. Blacklisting a device also makes it easier for the owner to find it.
Warranty and Insurance
The warranty and insurance status of a device can be checked using the IMEI by manufacturers and network providers. For instance, if an item is covered by a warranty, the maker will repair or replace it at no cost. When a gadget is reported lost or stolen, insurance firms can also check the IMEI to confirm the validity of the item.
Software Updates
The IMEI can be used by manufacturers to determine if a device qualifies for a software update. This implies that the update will only be applied to devices that meet specified requirements, such as a particular model or firmware version.
Analytics and Marketing
Data about device usage can be collected via the IMEI and utilised for analytics and marketing purposes. Manufacturers and network operators can utilise this to understand how their products are being used and spot use trends or patterns.
Customizing Services
Services for certain devices can be tailored using the IMEI. For instance, depending on the kind of device a consumer is using, a network operator may offer them various plans or services.
Fraud Detection
IMEI can be used to track the mobility of devices to spot and stop fraud. A device might be highlighted as a possible fraud case, for instance, if it is reported as lost or stolen but is later discovered to be in use.
Device Configuration
A device's settings and applications can be configured by manufacturers using the IMEI. For instance, the IMEI of the smartphone may be used to lock or unlock particular apps or settings.
Law Enforcement
In the event of a criminal inquiry, IMEI can be used to monitor and identify a device. For instance, the IMEI can be used to track down a device that was used in the commission of a crime to the person who was in possession of it at that time.
