Let’s look at the pros and cons of different approaches, how they interact with each other and explain why we recommend BIN validation be part of your strategy for most applications. (We’re a little biased.) But we are just part of the best practices you should have in place to protect your business.
What is the best way to validate a credit card? You would probably expect us to say “ours.” And often, of course, that would be correct.
#BIN CC CHECK HOW TO#
How to validate a credit card: the short course The next five digits are used to specify the issuing institution as well as the type of card, such as credit, debit or gift cards.Other values of this first digit are reserved for other types of issuers such as airlines, gas stations, and retailers.But your American Express card starts with a “3,” because of its history as a so-called “travel and entertainment” card. Most true credit cards start with a 4 or 5, signifying financial institutions.Under either name, here are some fun facts about the BIN, courtesy of Sapling: Your first line of defense in preventing fraud lies with first six digits of this credit card number, commonly known as Bank Identification Number (BIN), but increasingly being called by the broader term of Issuer Identification Number (IIN). These 16 digits pack a lot of useful information about the card besides its account number. It all starts with the numberĮver wonder why you can’t just make up 16 random digits and call it a credit card number? Because the various parts of this number each have specific roles, ranging from the type of issuer in the first digit, to a checksum digit at the end based on a mathematical formula involving the other digits. So knowing your business needs and your options are the keys to being an educated and protected credit card processing merchant. If you try to maximize your sales through more relaxed business rules, you may get eaten alive by fraudulent transactions and chargebacks – or even lose your merchant account and ability to do business. If you use a strict approach to flag suspicious cards, you may also lose a lot of sales (and still have fraud issues). You see, there is no single “best” approach to credit card validation. This is one area where knowledge is truly power.
