These digits are carefully assigned by card networks and financial institutions to encode specific information related to the card's issuer and characteristics. The structure of BIN numbers is standardized across the industry, enabling seamless identification and validation. ## Issuer Identification: The first digit of a BIN number is known as the Major Industry Identifier (MII), which signifies the category of the card issuer. MII digits range from 1 to 9 and have distinct meanings. For example, 4 and 5 represent banking and financial institutions, while 3 represents travel and entertainment cards. ## Bank Identification: Following the MII digit, the next five digits of the BIN number represent the Bank Identification portion. These digits identify the specific financial institution that issued the card. Each institution is assigned a unique range of BIN numbers, enabling easy identification of the issuing bank or organization. BIN numbers provide insights into the type and brand of the card. The combination of the MII digit and specific ranges within the BIN helps determine whether the card is a credit card, debit card, prepaid card, or another type of payment card. Additionally, BIN numbers can reveal the card's brand, such as Visa, [Mastercard](https://www.mastercard.co.in/en-in.html), [American Express](https://www.americanexpress.com/en-in/), Discover, or other regional card networks. ## Country of Origin: The BIN number also offers valuable information about the country of origin of the card. Typically, the first digits or ranges within the BIN are designated for specific countries or regions, providing a clue about the geographical location associated with the card. This information is useful for various purposes, including geolocation verification and fraud detection. Certain BIN numbers encode details about the card's level or tier within a particular payment network. For example, different levels such as classic, gold, platinum, or business cards may have specific BIN ranges assigned to them. This allows easy identification of the card's privileges, benefits, and associated features. ###### tags: `binsearch` `binchecker` `creditcardbinsearch` `binfinder`
