You probably know the concepts of SIM and IMEI, but not so much that of ICCID code. Let’s find out what it is and what role it plays in the world of mobile devices, because although it is usually a code that goes unnoticed, it is of paramount importance.
What is the ICCID code
The ICCID is a unique numerical sequence usually consisting of 18 to 22 digits, with 19 or 20 digits being the most common. This string of numbers is structured as follows.
The first two digits indicate that it is a telecommunications SIM card. The country code identifies where the SIM card was issued. The mobile network code or MNC identifies the mobile network provider.
The account number or individual identifier (II) makes each SIM card unique. Finally, a check digit at the end to validate the integrity of the number.
What is it for?
The ICCID code serves several important functions in the mobile telecommunications ecosystem. ICCID allows mobile network providers to uniquely identify and authenticate each SIM card. When a SIM card is activated, the device automatically searches for available mobile networks and the operator uses the ICCID to verify the identity of the card and authorize access to the network. In short, this allows the device to communicate with the mobile network.
In the field of the Internet of Things, the ICCID makes it easier to manage a large number of connected devices. It allows businesses to distinguish between different devices in a SIM management platform, check device status, and provide a reference point for specific queries. ICCID is also required in some telephone companies to perform portability, although this is no longer very common.
The ICCID is also unique, ensuring that each SIM card, or eSIM, can be uniquely identified and help protect user identity, as well as prevent fraud.
Where to find the ICCID
The ICCID code can be located in several ways. If you have a physical SIM card, you will find it written on it. You will also find it on the device itself, just go to the Settings section and navigate through the menu until you find the phone information.
Making code of utmost importance should logically not be shared with anyone, as it is a necessary element when carrying out mobile communications. And thanks to this code you will not only be able to activate the SIM card, The associated telephone number is also identifiedmay be involved in duplication, besides portability or in the blocking or cancellation of telephone lines.
