The ICCID is made up of: Issuer identification number (IIN) Maximum of seven digits: Major industry identifier (MII), 2 fixed digits, 89 for telecommunication purposes. Country calling code, 1 to 3 digits, as defined by ITU-T recommendation E.164. North American Numbering Plan countries use 1; Russia uses 7
This list contains the mobile country codes and mobile network codes for networks with country codes between 300 and 399, inclusively – a region that covers North America and the Caribbean.
The mobile country code consists of three decimal digits and the mobile network code consists of two or three decimal digits (for example: MNC of 001 is not the same as MNC of 01). The first digit of the mobile country code identifies the geographic region as follows (the digits 1 and 8 are not used): 0: Test networks; 2: Europe
An IMSI is usually presented as a 15-digit number but can be shorter. For example, MTN South Africa's old IMSIs that are still in use in the market are 14 digits long. The first 3 digits represent the mobile country code (MCC), which is followed by the mobile network code (MNC), either 2-digit (European standard) or 3-digit (North American ...

With the GSM Phase 1 specification using 10 octets into which ICCID is stored as packed BCD [clarification needed], the data field has room for 20 digits with hexadecimal digit "F" being used as filler when necessary. In practice, this means that on GSM cards there are 20-digit (19+1) and 19-digit (18+1) ICCIDs in use, depending upon the issuer.
The hexadecimal form is specified to be 14 digits grouped together and applies whether all digits are in the decimal range or whether some are in the range 'A'–'F'. In the first case, all digits are in the range '0'–'9', the check-digit is calculated using the normal base 10 Luhn algorithm, but if at least one digit is in the range 'A'–'F ...
The Long Form EUIMID is the ICCID that has been present in many generations of smart cards, including the SIM cards for GSM. This is composed of up to 18 BCD digits -- up to 72 bits. The storage allocated for the ICCID is, however, 80 bits, so it is recommended that the Luhn check digit be included plus a padding digit (0xf).
