What is an IMEI Number ?

IMEI stands for International Mobile Equipment Identity. It is a unique 15-digit number assigned to every mobile device that uses cellular networks. The IMEI number is used to identify valid devices and can be used to stop a stolen phone from accessing cellular networks. It can be found on the device itself, typically under the battery or on the box it came in. It also can be obtained by dialing *#06# on the device.

There are two types of IMEI numbers:

1. The original IMEI number, which is assigned by the manufacturer at the time of production and is stored on the device's firmware.
2. The duplicate IMEI number, which is assigned by the service provider and is used as a replacement for the original IMEI in case the device is lost or stolen.

It's worth noting that using a fake or cloned IMEI number is illegal in most countries and can result in your device being blacklisted by the network operator.

There are 10 ways to find the IMEI number on a device:

1. Dial *#06# on the device. This will display the IMEI number on the screen.
2. Check the back of the device or the battery compartment. The IMEI number is often printed on a sticker on the back of the device or on the battery compartment.
3. Check the device's original packaging or documentation. The IMEI number is often printed on the box or in the documentation that came with the device.
4. Check the device settings. On most devices, you can find the IMEI number by going to the "About" or "Settings" menu and looking for it.
5. Check the SIM tray. On some devices, the IMEI number may be printed on the SIM tray.
6. Check the device's warranty card. The IMEI number may be printed on the warranty card that came with the device.
7. Use a computer. If the device is connected to a computer, you can often find the IMEI number by opening the device manager and looking for the device's properties.
8. Use the device's original charger. Some chargers have the IMEI number printed on them.
9. Check the device's bill of sale. If you have the device's bill of sale, the IMEI number may be listed on it.
10. Use a phone IMEI checker online. There are several online tools available that can help you find the IMEI number of a device by inputting its brand and model.

Please note that depending on the device and how old it is, not all these tricks may work, so it is advisable to try all the methods above to find your IMEI

Organizations Registering IMEI

The International Mobile Equipment Identity (IMEI) number is a unique number assigned to every mobile device to identify it internationally. The registration of IMEI numbers is managed by the International Telecommunication Union (ITU) and the International Mobile Equipment Identity (IMEI) Database. The ITU assigns a unique TAC (Type Allocation Code) to each mobile device manufacturer, which forms the first 8 digits of the IMEI number.

The organizations that register IMEI numbers include:

• The International Telecommunication Union (ITU)
• The Global System for Mobile Communications (GSM) Association
• The International Mobile Equipment Identity Database (IMEI DB)
• The European Telecommunications Standards Institute (ETSI)
• The Telecommunications Industry Association (TIA)

These organizations work together to ensure that every mobile device has a unique IMEI number and that the IMEI database is up-to-date and accurate. They also help to prevent the use of fake or cloned IMEI numbers and assist in tracking lost or stolen devices

Explain 15 digit IMEI Number in detail:

An International Mobile Equipment Identity (IMEI) number is a 15-digit unique code that is assigned to every mobile device. It is used to identify the device internationally and can be used to track the device if it is lost or stolen. The IMEI number is divided into several parts, each with a specific meaning:

1. Type Allocation Code (TAC): The first 8 digits of the IMEI number make up the TAC, which is assigned by the International Telecommunication Union (ITU) to each mobile device manufacturer. This code is used to identify the manufacturer and model of the device.

2. Final Assembly Code (FAC): The next 6 digits of the IMEI number make up the FAC, which is assigned by the manufacturer. This code is used to identify the specific production location of the device.

3. Serial Number (SNR): The last digit of the IMEI number is a check digit, which is used to validate the IMEI number.

The TAC and FAC are used to identify the manufacturer and location of production, while the SNR is used to validate the IMEI number. The IMEI number can be used to track a device if it is lost or stolen, and can also be used to verify the authenticity of a device. It is also used by service providers to identify a device on their network and to activate mobile services
