Every credit card issued is comprised of a series of numbers that identifies the credit card issuers and card account identifier. Credit Card numbers usually ranges from 13 digits to 19 digits but are different among issuers.
The first six digits of the card number is the “issuer identification number (IIN)”, sometimes referred to as the “bank identification number (BIN)”. The remaining numbers (last 11 or 12 numbers) on the card are referred to as the primary account number or PAN.
