What is an IMEI number?

Let’s first address the elephant in the room. 

You will find an IMEI number in every GSM modem, mobile phone, or any other device that has a built-in phone or modem that you have purchased. This is a 15-digit unique number. This means that no two devices will ever have the same IMEI, no matter where it’s built in the world. 

The main purpose of this number is to find and check all the information related to the device. It could be its model, brand, whether the phone has ever been blacklisted or not, and other pieces of important information. 

It is best used when you are planning to buy a used phone and you cannot really trust the seller that you are buying the phone from. 

It is also useful when someone loses their phones. It makes it easy to block the device. 

How to check the IMEI number?

The best thing about the IMEI number is that it is truly very easy to check. There are plenty of websites like Gizmogo that offer free IMEI checker. You just need to follow the below-mentioned steps to find all the information that you need. 

  • Dial *#06# to find out what your IMEI number is. 
  • Take the CAPTCHA test. 
  • Once you pass, click the button and check your number in the international database. 
  • Verify that the phone you are planning to purchase is not blacklisted anywhere in the world. 

Why should you check IMEI?

Many believe that checking the IMEI number is just an additional step before purchasing the phone. After all, the decision has already been made. 

However, you can never be too sure whether the information that is given to you is accurate or not. 

When you check your IMEI, here is the information that you will be able to find: 

  • Information about the warranty of the product. 
  • Specifications of the device. 
  • The true origin of the device and the network that it’s using currently. 
  •  Cell phone carrier lookup. 
  • The version of the system at present. 

These are just a few of the many pieces of information that you can find about the second-hand device you are planning to purchase. It is always better to be safe than sorry.

When is the right time to check your IMEI?

It is obvious that you can’t just go on about checking your IMEI every now and then. Or of every phone that you come across. 

You should always, however, remember to check the IMEI of the mobile phones before you pay for a used device. You won’t be able to back down if you pay the seller and then find issues in the information that was presented to you earlier. 

When you check the IMEI before purchasing, you will be able to determine if the product that is listed is original and valid or not. 

You can also cross-check if the specifications that were told to you by the seller were accurate or not. It is also often suggested to check the IMEI to know the product better before you purchase the same. 


To conclude, we can say that it is always better to check the IMEI number, especially when you are in the process of buying a used phone. You don’t want to spend your money on a device that has been blacklisted, no matter how cheap the product is being sold for.
