How To Use The IMEI Number To Locate Your Cell Phone

We know that the IMEI code is one of those terms that is related to cell phones, but, in reality, a lot of us don’t understand much about it, let alone know what it’s used for.

However, knowing your cell phone’s IMEI is important, and could be useful in different situations. Below, you will find all of the information that you’ll need to know to understand what an IMEI code truly is, how to find yours, and whether or not it’s true that it could be used for tracking your cell phone.

What’s an IMEI code?

IMEI means “International Mobile Station Equipment Identity.” In Spanish, it could be translated to “Identidad Internacional de Equipos Móviles.”

Just as its name indicates, the IMEI is a unique code that is used for identifying a device and distinguish it from any other in the world. This code is neither related nor relies on your phone number, SIM card nor carrier. Instead, it belongs to the device itself.

You could change your phone number, remove the SIM card, or change your service provider, and the IMEI code would remain the same. Even two identical devices that have the same model, software version, color, and date of creation will have their own IMEI, which will be different from any other device.

The IMEI code is usually comprised of 15 or 17 numbers, although, in some cases, the last digit is omitted. These digits are divided into four parts that contain different information, such as the approved organization that assigned the number, information about the manufacturer, and the device’s serial number.

Some codes use the last digit to verify the validity of the entire code using an algorithm known as the Luhn Algorithm, while other codes omit the last digit or end in 0.

You may also have heard about an IMEISV or IMEI/SV code. In this case, “SV” means “Software Version,” and it simply is the same IMEI code, where the software version is added as two digits at the end of the code. The IMEISV has been used since not too long ago, and it is only available on the most recent devices.

Some 3G tablets also have an IMEI code, while Wi-Fi-only tablets tend to not have it. Likewise, a lot of disposable phones, as well as phones without a contract, don’t have an IMEI code either.
