What is ICCID Number | How to find ICCID number?

Have you ever looked at your SIM card and noticed a long string of numbers? That's the ICCID number, a crucial puzzle in mobile communication. Standing for Integrated Circuit Card Identifier, the ICCID is your SIM card's unique identifier, playing a key role in connecting your device to the mobile network. The ICCID is essentially your SIM's identity code that mobile operators use to authenticate and authorize your subscription and service access. No two SIM cards can have the same ICCID, so this number is critical for proper network provisioning and billing.

For eSIMs, the ICCID not only enables initial network authentication but also allows for the remote management of multiple operator profiles on a single chip. This flexibility is key to eSIM's advanced capabilities like swapping carriers seamlessly without physical SIM swaps. We'll dive deeper into understanding ICCIDs, why they matter for cellular connectivity, where to find this number on your phone, and how they enable the power of eSIM technology. First, let's start with the basics of what an ICCID represents.

What is ICCID Number? 

The ICCID number is like the ID card for your SIM card, making sure your phone can connect to the mobile network. Standing for Integrated Circuit Card Identifier, this 19-20 digit long serial number is unique to each SIM card. It tells your mobile provider which card is yours so you can make calls, send texts, and use data.

Why do ICCID numbers matter? 

They're key to setting up your phone's service. Without the ICCID, mobile providers wouldn't know which SIM card is linking to which network account. This number also helps when you're switching phones or providers, making sure your new setup works smoothly without having to get a new SIM card every time. In short, the ICCID keeps your phone connected and your service running just right.

How to find the ICCID number?

Finding your ICCID number, the unique code that identifies your SIM card is straightforward. Here’s how you can do it:

ICCID Number iPhone: 

• Tap on the "Settings" app. 
• Then head to "General".
• Select "About." Scroll down the list until you find the ICCID. It’s a long number, so make sure you scroll down.



ICCID Number Android: 

The process might vary slightly depending on the brand and model. Generally, you'll start by opening "Settings." Look for "About Phone" or "About Device," then tap on "Status" or sometimes "IMEI Information." Here, you should find the ICCID listed among other details. If it's not immediately visible, you might need to explore similar options like "SIM Status" to find it.

On the Packaging of SIM Card:

If you’ve kept the original packaging of your SIM card, you’re in luck. The ICCID is often printed on a label or sticker on the card’s packaging, along with other information like the barcode. This can be particularly helpful if you can’t turn on your phone or access the settings for some reason.

Contacting Your Mobile Carrier:

When other methods don’t work or if you need the ICCID for a SIM card that’s not currently in a phone, your mobile carrier’s customer service can help. After verifying that you’re the owner of the account, they can provide you with the ICCID number. Make sure to have your account details handy when you call or chat with them for a smoother process.

ICCID number on SIM Card:

The ICCID number on your SIM card is like a special code that identifies your SIM card to your mobile network. Here's a bit more about it and how you can find it:

If your phone allows, you can remove the SIM card tray and take out the SIM card. The ICCID is usually printed on the body of the SIM card itself. It’s a series of numbers, and you might need a magnifying glass to read it clearly because the print can be quite small.

Information about ICCID Number:

Newer SIM cards feature a 19-digit ICCID number, while the older versions contain a 20-digit code.

• Every SIM card has a special number called an ICCID. This number starts with "89," a code that tells us it's for the telecommunications world, setting it apart from other types of cards like credit cards or IDs.
• First off, after the "89," there's a country code that can be 2 or 3 digits long. This code comes from the International Telephony Union and shows which country the SIM card comes from. It's different from the codes used in phone numbers.
• Then, we have the mobile network code (MNC). This part, which can be from 1 to 4 digits, tells us which mobile network the SIM belongs to. It's like the SIM card's home. Sometimes, if you use your phone in another country, this code helps your phone get service from a local network. Because of deals between different phone companies, the network on your SIM card might show a partner company's code instead of the one you bought it from.
• The rest of the ICCID is a unique number that makes sure no two SIM cards are the same. At the very end, there's a check digit, added for extra security to make sure the whole number is correct.



When you need to talk to your phone company—like checking your account, starting a service, or getting help—the ICCID number is what you'll use. It's the key to making sure your phone has the service it needs to make calls, send texts, and use data.

ICCID vs Other Identifier

In the world of mobile technology, ICCID, IMEI, and EID are key identifiers, each serving a unique purpose:

1. IMEI identifies your mobile device. Unlike ICCID, which is tied to the SIM card, IMEI is specific to the device, helping in tracking and security, especially for stolen device blocking or warranty services.
2. EID is related to eSIM technology, identifying devices with an embedded SIM. It allows for managing eSIM profiles, enabling users to switch carriers digitally without physical SIM swaps.
