Identify credit card type and company by a card number
All credit card numbers adhere to strict standards of formatting. Each digit group number is assigned a numeric representation of a data block that identifies the issuing bank, credit card network type, and cardholder account number. Using a specific order of groups and numbers, a credit card number not only represents a specific user account that is used for processing inbound and outbound transactions but also a validation digit that flags the account number as either valid or invalid if misused.
Detecting a credit card type, company, and bank institution by a valid credit card number
In order to compile a complete data set from the credit card number, the number must be first validated and then analyzed by a database-driven procedure that allows obtaining detailed credit card information about the bank institution and type of the card with other appropriate pieces of information.
The anatomy of a credit card can be represented by the following example
A) Industry Identifier (MII) — specifies the major industry of the card. The leading number of the card number identifies the industries of usage as follows
MII digit category
0 – ISO/TC 68 & other industry assignments
1 – Airlines
2 – Airlines, financial & other future industry assignments
3 – Travel & entertainment
4 – Banking & financial
5 – Banking & financial
6 – Merchandising & banking/financial
7 – Petroleum & other future industry assignments
8 – Healthcare, telecommunications & other future industry assignments
9 – For assignment by national standards bodies
B) Card Institution Identification Number (IIN) — describes the issuer of the card. The full list of Card Issuer identification numbers can be found on wikipedia. Card issuers generally do not update the ranges frequently, however, if there’s an update, it should be published as provided in the linked page above.
C.) Cardholder’s account number.
D.) Validation ID (checksum) that provides a sequence with the account number to validate the actual number.
