Integrated Circuit Card ID (ICCID) is the unique identifier of a Subscriber Identity Module (SIM card) on a mobile device. ICCIDs are stored in the SIM cards and printed on the SIM card body. The ICCID is defined by the ITU-T recommendation E.118 as the Primary Account Number. A full ICCID is 19 or 20 characters containing the Industry Identifier (ISO), country code, issuer identity, account ID, and other data which allows the network operator to identify the card.
