BIN Checker: The Ultimate Guide to Bank Identification Numbers

Bank Identification Numbers (BINs) are the first 6-8 digits of a credit or debit card number that provide information about the card, such as the card network, issuing bank, country, card type, level, and category. BIN Lookup is a tool used to verify the validity of a BIN during transactions to prevent fraud and errors.

Introduction

If you have ever used a credit or debit card, then you must have noticed a string of numbers running through the front and back of the card. Those numbers are not entirely random, but they hold a real meaning, and they serve a particular purpose. They form part of the Bank Identification Number (BIN). It thus involves a special code indicating identification of the bank that issues the card network, the country as well as other details of the card.

However, why should you need to know BINs? How do you get to verify them? Keep reading as in this article, we answer some of those questions and more. We will explain what BINs are, how they work, why they are so important, and how you can use a BIN checker tool to verify them. Whether you're a merchant, a consumer or just curious, here is a simple guide to explain the basics of BINs and how to use them effectively.

What is a Bank Identification Number (BIN)?

BIN is the first 6-8 digits of the card number that identify the first part of the card number for credit and debit cards. The similar number, IIN stands for the Issuer Identification Number, since it identifies the issuer of the card, not necessarily being a bank.

The BIN tells you several things about the card, such as:

  • The card network: Visa, Mastercard, American Express, Discover, etc.
  • The issuing bank: The financial institution that issued the card to the cardholder.
  • The country: The country where the card was issued.
  • The card type: Credit, debit, prepaid, gift, etc.
  • The card level: Standard, Gold, Platinum, etc.
  • The card category: Personal, business, corporate, etc.

For example, let's look at this sample card number: 4111 1111 1111 1111

The first six digits are the BIN: 411111

This BIN tells us that:

  • The card network is Visa
  • The issuing bank is JPMorgan Chase Bank
  • The country is the United States
  • The card type is Credit
  • The card level is Standard
  • The card category is Personal

How does a BIN Lookup work?

In this light, a BIN Lookup serves both as the security and verification tool of the merchant and the consumer. For every transaction where you use your card to purchase something - be it online or offline, the payment processor of the merchant, or terminal he uses, will verify the validity of the BIN of the card number in a database of valid BINs. This process is called BIN validation or BIN verification.

BIN validation helps to prevent fraud and errors by ensuring that:

  • The card is genuine and not counterfeit
  • The card network and issuer are authorized and legitimate
  • The card is compatible with the merchant's payment system
  • The card has sufficient funds or credit limit to complete the transaction

If the BIN matches the database, the transaction can proceed. If not, the transaction will be declined or flagged for further review.

BIN validation also helps to provide a better customer experience by enabling features such as:

  • Dynamic currency conversion: Converting the transaction amount to the cardholder's local currency
  • Cardholder verification: Asking for additional information such as PIN or CVV to confirm the identity of the cardholder
  • Cardholder preferences: Applying discounts, rewards, or offers based on the cardholder's profile
