ICCID Validator

Understanding the ICCID Number

The ICCID (Integrated Circuit Card Identifier) is a unique serial number that identifies each SIM card internationally. It typically consists of 18 to 22 digits and is stored inside the SIM card. Our validator uses the Luhn algorithm to check the checksum of the ICCID, which is a common method for validating identification numbers.

What do the digits mean?

An ICCID number is composed of several parts:

• Major Industry Identifier (MII): The first two digits are always 89, representing the telecommunications industry.
• Country Code: The next 1-4 digits represent the country where the card was issued.
• Issuer Identifier Number (IIN): The next few digits identify the specific network operator that issued the card.
• Individual Account Identification: The subsequent digits are the unique account number for the SIM.
• Checksum: The final digit is calculated using the Luhn algorithm to ensure the integrity of the number.

Frequently Asked Questions

Why is my ICCID invalid?

An ICCID might be invalid due to a typo or an incorrect number. The final digit (the checksum) is calculated based on all the other digits. If even one digit is wrong, the Luhn check will fail.

Is this tool secure?

Yes, this tool is completely secure. The validation is performed in your browser, and we do not store or transmit any of the ICCID numbers you enter.
