In today’s world of smartphones and mobile devices, the IMEI number has become an essential piece of information for users, manufacturers, and network providers alike. But have you ever wondered what an IMEI number looks like? In this article, we will delve into the world of IMEI numbers, exploring their structure, significance, and importance in the mobile ecosystem.
What is an IMEI Number?
Before we dive into the details of what an IMEI number looks like, let’s first understand what it is. IMEI stands for International Mobile Equipment Identity, a unique 15-digit code assigned to every mobile device, including smartphones, tablets, and smartwatches. The IMEI number is used to identify a device on a cellular network, ensuring that it is legitimate and not stolen or counterfeit.
Structure of an IMEI Number
An IMEI number is composed of 15 digits, divided into several sections. The structure of an IMEI number is as follows:
- First 6 digits (TAC): The first 6 digits of the IMEI number are known as the Type Allocation Code (TAC). This section identifies the device’s manufacturer and model.
- Next 2 digits (FAC): The next 2 digits are the Final Assembly Code (FAC), which indicates the device’s assembly location.
- Next 6 digits (SNR): The next 6 digits are the Serial Number (SNR), which is unique to each device.
- Last digit (CD): The last digit is the Check Digit (CD), which is calculated using the Luhn algorithm to verify the IMEI number’s authenticity.
Example of an IMEI Number
Here’s an example of what an IMEI number might look like:
49-015420-176148-1
In this example, the first 6 digits (490154) represent the TAC, the next 2 digits (20) represent the FAC, the next 6 digits (176148) represent the SNR, and the last digit (1) is the CD.
How to Find Your IMEI Number
If you’re wondering how to find your IMEI number, there are several ways to do so:
- Check your device’s packaging: The IMEI number is usually printed on the device’s packaging or on a sticker attached to the device.

Final Thoughts
As we continue to rely on mobile devices in our daily lives, the importance of the IMEI number will only continue to grow. By understanding the IMEI number and its significance, we can better protect ourselves and our devices from theft, loss, and malicious activities. So next time you see an IMEI number, remember the important role it plays in keeping your device safe and secure.
What is an IMEI number and how is it used?
An IMEI (International Mobile Equipment Identity) number is a unique 15-digit code assigned to every mobile device, including smartphones, tablets, and smartwatches. It is used to identify the device on a cellular network and is typically found on the device’s packaging, in the device’s settings, or on the device itself. The IMEI number is used by network operators to authenticate and authorize devices on their networks, ensuring that only legitimate devices can access their services.
The IMEI number is also used by law enforcement agencies to track and locate stolen devices. When a device is reported stolen, the network operator can use the IMEI number to block the device from accessing their network, making it difficult for the thief to use the device. Additionally, the IMEI number can be used to unlock a device that has been locked to a specific network, allowing the device to be used on other networks.
How do I find my IMEI number?
There are several ways to find your IMEI number, depending on the type of device you have. On most devices, you can find the IMEI number in the device’s settings. For example, on an iPhone, go to Settings > General > About, and the IMEI number will be listed. On an Android device, go to Settings > About phone > Status, and the IMEI number will be listed. You can also find the IMEI number on the device’s packaging or on the device itself, usually on the back or bottom.
If you are unable to find your IMEI number using these methods, you can also dial a code on your device to display the IMEI number. The code is *#06#, and it works on most devices. When you dial this code, the IMEI number will be displayed on the screen. You can then write down the IMEI number or take a screenshot of it for future reference.
What is the difference between an IMEI number and a serial number?
An IMEI number and a serial number are both unique identifiers assigned to a device, but they serve different purposes. An IMEI number is used to identify a device on a cellular network, while a serial number is used to identify a device for warranty and repair purposes. The serial number is usually found on the device’s packaging or on the device itself, and it is used by the manufacturer to track the device’s production and distribution.
While both the IMEI number and the serial number are unique identifiers, they are not interchangeable. The IMEI number is specific to the device’s cellular capabilities, while the serial number is specific to the device’s hardware and software configuration. If you need to provide identification for your device, it’s essential to use the correct identifier, whether it’s the IMEI number or the serial number.
Can I change my IMEI number?
It is not recommended to change your IMEI number, as it can have serious consequences. The IMEI number is a unique identifier that is assigned to your device by the manufacturer, and it is used by network operators to authenticate and authorize devices on their networks. Changing the IMEI number can cause problems with your device’s connectivity and may even render it unusable.
Additionally, changing the IMEI number can also be illegal in some countries, as it can be used to disguise a stolen device. If you need to unlock your device or change its network configuration, it’s recommended to contact the manufacturer or a authorized service provider, who can assist you with the process without changing the IMEI number.
How do I check if my IMEI number is blacklisted?
If you suspect that your IMEI number is blacklisted, you can check it using an online IMEI checker tool. These tools allow you to enter your IMEI number and check its status on various networks. You can also contact your network operator directly and ask them to check the status of your IMEI number.
If your IMEI number is blacklisted, it means that it has been reported as stolen or lost, and it may not be able to access certain networks. In this case, you may need to contact the network operator or the device’s manufacturer to resolve the issue. They may be able to remove the blacklist or provide additional assistance to restore your device’s connectivity.
What are the consequences of having a blacklisted IMEI number?
If your IMEI number is blacklisted, it can have serious consequences for your device’s connectivity. A blacklisted IMEI number can prevent your device from accessing certain networks, making it difficult or impossible to make calls, send texts, or access data. In some cases, a blacklisted IMEI number can even render your device unusable.
Additionally, a blacklisted IMEI number can also affect the device’s resale value. If you try to sell a device with a blacklisted IMEI number, the buyer may not be able to use it, which can reduce its value. In some cases, a blacklisted IMEI number can even lead to the device being confiscated by law enforcement agencies, if it is reported as stolen.
How can I protect my IMEI number from being stolen or compromised?
To protect your IMEI number from being stolen or compromised, it’s essential to keep it confidential. Avoid sharing your IMEI number with unauthorized parties, and be cautious when providing it to third-party services or apps. You should also keep your device’s software up to date, as newer versions often include security patches that can protect your IMEI number.
Additionally, you can also use a device locking feature, such as Find My iPhone or Android Device Manager, to protect your device in case it is lost or stolen. These features allow you to remotely lock or erase your device, which can help protect your IMEI number and prevent it from being used by unauthorized parties.
