BIN Lookup API - 2020

Posted by binsearch on September 2nd, 2020

There is always a Bank Identification Number (BIN) for the credit/debit card. That number will be on your card, and the first four to six numbers will appear on it. It is basically for identifying the institution issuing the card. The BIN Search tool is used for getting issuer details like bank and branch from where the card has been issued.

This API is ideal for fraud protection systems and payment analysis. Find out the card type, country and full issuer details for the given BIN number.

Our BIN database is comprehensive and works with 6, 8 and 10 digit BINs from all countries. We update the database on a weekly basis as new cards are issued.

This API also includes some extra fraud detection measures if a customer IP address is passed in. In this mode the API will also perform IP geolocation and IP blocklist lookups.

The payment industry is moving from 6-digit to 8-digit BINs due to BIN number exhaustion. The ISO announced that full implementation of the new standard is required by April 2022.

API fully supports 8-digit (and higher) BINs and we recommend if your still using 6-digit BINs that you begin transitioning to 8-digit BINs as soon as possible.

The BIN code also referred as IIN code definition as per Wikipedia is:

The first six or eight digits of a card number (including the initial MII digit) are known as the issuer identification number (IIN). These identify the card issuing institution that issued the card to the card holder.

The rest of the number is allocated by the card issuer. The card number’s length is its number of digits. Many card issuers print the entire IIN and account number on their card.


What it is used for?


The BIN code can be used to get the meta information about the card such as issuer institution information, country of card origin and country information plus card basic information such as Bank Account Number (PAN) Length,CVV length and whether the card has Luhn algorithm check or not.
All of this information can be useful for

  • Financial institution to identify the card holder for reporting purposes.
  • Also, it does play a crucial part in the Fraud Management systems, for example, if the system knows the card origin and some fraudster is trying to use the card frequently far a way from the destination.
  • Financial settlement systems, specially in Banking sector to define whether the card is credit or debit.

The BIN identifies the issuer of the card. This issuer receives the authorization request for the transaction to verify if the card and associated account are valid and whether the purchase amount is available.

This process results in the charge being either approved or denied. Without a BIN, the credit card processing system would be unable to determine the origin of the customer's funds and would be unable to complete the transaction.


The Problem


Here comes the problem, Identifying card metadata is always a problem, because there is no central public or private source for getting such information and there are hundred of free or paid services out there trying to solve this issue, but either it is abandoned or outdated.


Solution


In This article I would like to shed some light on the BIN Lookup tool, the service does have a pretty huge and updated database plus also provides a Free BIN Lookup API.

I’ve run a couple of tests using my card BIN and some family members cards and the result were accurate.
Also, this service is a community powered partially where you can do pull request on their GitHub repo. if you noticed any missing data.I hope you guys can give it a try and leave a comment about your experience.
