What Is An ICCID Number And Why Should You Care?

The ICCID number is a code that allows you to uniquely identify your SIM card on a mobile network. But, if you’ve lost your android phone or have had it stolen, then it can be difficult to track down your iPhone or Android phone. That’s where our well-researched article comes in handy!

What Is The ICCID Number On Your Phone?

The ICCID is 19 or 20 numbers that uniquely identify your SIM card. It’s made up of individual parts that identify the card issuer, country of origin, and other details.

Integrated Circuit Card Identifier (ICCID) can be found on the SIM card itself – just look under the phone’s battery.

The number is also printed on the card packaging, and it should be noted in your phone’s documentation.

If you need to find your ICCID number but your SIM card is invalid, you can also dial *#06# on your phone to get the number displayed on the screen.

Why Is ICCID Important?

The ICCID is important because it’s used to identify your specific SIM card and therefore your mobile phone number.

This means that if you lose your iPhone or Android or if it’s stolen, anyone who finds it can’t just use a new SIM card with your phone and start making calls – they need your ICCID first.

If you’re planning on traveling overseas, you’ll need to make sure you have your ICCID handy so that you can activate a local SIM card when you arrive at your destination.

Similarly, if you’re buying a new phone and transferring your old SIM card to it, you’ll need the ICCID to do so.

In short, the ICCID is an important piece of information linked to your SIM card and therefore your mobile phone number. Keep it in a safe place so that you can access it when you need it.

How To Find ICCID Number?

There are a few ways you can do to find your ICCID number. You can identify your ICCID by checking the back of your card SIM. Also, you can find your ICCID number in your smartphone settings. To locate the ICCID number on your phone:

Go Phone Settings app


Find “General options,” and click on it.


From there, tap “About” and look for “ICCID.”


Your ICCID number will be listed there. If you still can’t find your ICCID number, contact your carrier’s support center.

Should I Give Out My ICCID Number?

You should be mindful of when you should let someone know your ICCID number. Some people argue that it’s a necessary part of owning a cell phone, while others believe that it’s an invasion of privacy.

So, what’s the verdict? The ICCID number is essentially your phone’s serial number. This is an identification number that’s used to identify the SIM card. It’s necessary when you face the SIM card not working and other problems.

On the other hand, giving out your ICCID number also allows people to access personal information about you, such as your contact list and call history.

If your Android or iPhone device is ever lost or stolen, someone with your ICCID number could potentially activate a new SIM card in your phone and use it for their own purposes.

So, should you give out your ICCID number? Ultimately, the decision is up to you. You shouldn’t share things that you’re not comfortable sharing with others.

But if you’d prefer to keep your information private, then it’s best to keep your ICCID number to yourself.

What Can Someone Do With My ICCID Number?

If someone has your ICCID number, they can potentially exploit it to gain access to your personal information or commit fraud. However, there are ways to protect yourself from this type of attack.

It is important to never give your ICCID number to anyone if you don’t know them. Second, keep your ICCID number safe and secure by storing it in a secure location such as a password-protected file or encrypted database.

If someone has your ICCID number, they can:

  • Activate a new phone with your SIM card
  • Port your phone number to another carrier
  • Access your account if you’re using a prepaid service
  • Duplicate your card SIM (and use it on another phone)

If you believe your ICCID number has been stolen, contact the service provider to make sure they monitor your account closely.

How To Find 20 Digit Number If You Don’t Have The SIM Card?

If you need to find your SIM card’s 20-digit number without a SIM card, look in your phone settings. Your SIM card number should be listed under “SIM information” or something similar.

Secondly, you can find the SIM card number from the IMEI number on your device or check the phone box. Also, from your phone, dial *#06#, then press the call button. The IMEI number is a 15 or 16-digit code that uniquely identifies your device.

You may be able to find your SIM card number by checking the “About phone” section. Another way is to contact your service provider. They should be able to give you the number over the phone or through their website.

How To Change The SIM Card ICCID Number?

If you need to change your SIM card ICCID number for any reason, it’s actually very easy to do. Here is a quick guide on changing SIM card ICCID number:

  • Find the ICCID number on your existing SIM card. It’s generally located on the back of the card, or in your phone’s settings menu.
  • Write down the ICCID number, or take a screenshot of it.
  • Reach out to your carrier provider and explain to them that you require to change your SIM card ICCID number. They will give you a new SIM card and update the ICCID number
  • Enter the new SIM card and activate it per your provider’s instructions. Your SIM card has been successfully changed.

Is ICCID The Same As SIM Card Number?

Most people don’t know what an ICCID is, let alone that it’s different from a SIM card number. So the first thing you need to know is that each SIM card has a unique ID associated with it called an ICCID.

It’s made up of 19-digit numbers and can usually be found on the back of the card. A SIM card number, on the other hand, is also unique to your card.

But it’s only made up of 14-16 digits. And it’s not necessarily printed on the card (though sometimes it is).

Now that we’ve got that straight, let’s answer the question: are ICCIDs and SIM card numbers the same? The response is no, they’re not the same.

The long answer is straightforward. In some cases, your ICCID may be the same as your SIM card number. But in other cases, it won’t be. It all depends on your carrier settings and what type of SIM card you have.

What Is The Difference Between ICCID And IMSI?

There are a few acronyms important to know when it comes to Android phones. ICCID and IMSI are two of these acronyms, and they both refer to different things.

The Integrated Circuit Card ID is the unique identifier for a SIM card. IMSI stands for International Mobile Subscriber Identity, and it is the unique identifier for a particular subscriber on a cellular network.

So what’s the difference between ICCID and IMSI? Put simply, ICCID is used to identify the SIM card itself, while IMSI is used to identify the subscriber that is using that SIM card.

This means that if you were to switch SIM cards, your device would still have the same ICCID, but it would have a different IMSI. Knowing the difference between ICCID and IMSI can be helpful in a number of situations.

For example, if you’re troubleshooting an issue with your mobile service, your carrier may ask for your ICCID or IMSI in order to help them narrow down the problem.


The ICCID number is a unique identifier for your SIM card. It’s used to identify both the card and the device it’s in. The ICCID number is also stored in the device’s memory, so even if you switch SIM cards, your iPhone or Android phone will still be able to identify you by your ICCID number.
