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
The Luhn algorithm or Luhn formula, also known as the "modulus 10" or "mod 10" algorithm, named after its creator, IBM scientist Hans Peter Luhn, is a simple check digit formula used to validate a variety of identification numbers.
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).
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 ...
MIN1 is the first or least significant 24 binary digits of the MIN. MIN2 is the second part of the MIN containing the 10 most significant binary digits. MIN1, and the ESN, along with other digital input, are used during the authentication process. The MIN is used to identify a mobile station.
[1] The MSISDN and international mobile subscriber identity (IMSI) are two important numbers used for identifying a mobile subscriber. The IMSI is stored in the SIM (the card inserted into the mobile phone), and uniquely identifies the mobile station, its home wireless network, and the home country of the home wireless network.
The security code: Security codes on credit cards are often referred to as card verification values (CVV) or card verification codes (CVC). These codes are three or four digits on their own, and ...
Percent-encoding a reserved character involves converting the character to its corresponding byte value in ASCII and then representing that value as a pair of hexadecimal digits (if there is a single hex digit, a leading zero is added).
