The number 5 is the first digit of all account numbers associated with which major credit card? Explain

Credit card numbers adhere to a universal framework known as the Major Industry Identifier, in which the initial digit discloses the network or sector linked to the card. MasterCard cards consistently commence with the digit 5, distinguishing them from other prominent networks: Visa cards commence with 4, American Express with 34 or 37, and Discover cards generally with 6. These markers enable banks, retailers, and payment processors to swiftly identify the card network and routing mechanisms. This structured numbering system plays a pivotal role in maintaining order within the financial landscape.
