What is an ICCID (Integrated Circuit Card Identification) Number?

The ICCID Number stands for Integrated Circuit Card ID. It is an 18-22-digit number typically printed on the back of a SIM card. No two SIM cards have the same ICCID number.

The ICCID is a globally unique serial number – a one-of-a-kind signature that identifies the SIM card itself. It is used in the Infobip IoT module and in reporting to identify IoT sims.

Since the ICCID number is used to manage SIM cards, being able to locate it is crucial. It is usually on the card itself or printed on the packaging. Also, you can find the number when inserting a SIM card into a device and going to the settings menu (General > About).

IMSI and ICCID are part of the SIM profile, but the IMSI identifies the subscriber, and the ICCID identifies the SIM card. Since each SIM card has a unique ICCID number, sometimes it is called the SIM Card Number.

The format for ICCID Number is MMCC IINN NNNN NNNN NN C x

MM – most SIM Cards have the same first two digits – 89.
CC – county code, or MCC (Mobile County Code), used to identify a mobile subscriber’s county of origin.
II – SIM card issuer identifier, or MNC (Mobile Network Code), is used to identify a specific mobile network provider. This code is vital for roaming in different countries.
N – letters N stands for SIM number or account ID. These numbers are what make the SIM card unique.
C – the sum of previous digits using the Luhn algorithm.
x – extra digit that ICCID officially does not include as a part of the number.
