About CardDetails.com

CardDetails publishes details on payment cards using ISO/IEC 7812 - most commonly Credit and Debit cards.

Why does CardDetails exist

Online stores, businesses and payment processors accept credit and debit cards for payments for goods and services every day, but fraud and acceptance problems are a constant challenge.
The more information the processor has about the card that's being used to pay, the easier it is to detect fraud.

For example, if a customer in France is using a pre-paid debit card from Africa then this is a strong signal for a high fraud probability. With this additional information the company can decide to whether to accept the payment with the increased risk. Perhaps it makes sense to take the risk for a digital product with a minimal marginal cost, but not for a physical product that would be harder to recover in the event of a fraudulent payment.
That decision is up the company, but now they have more information with which to make that choice.

Who we are building for

• Companies needing to make more informed risk decisions
• Payment processors reducing fraud
• Data Analysts monitoring payment patterns

How we ensure data quality

Data quality is essential to the success of CardDetails - it's what makes our data so valuable.
But, card numbers can change - They are allocated to Issuers by the networks, but Issuers can request additional numbers when they get more customers and need to issue more cards, can be returned to the networks for reallocation or can get re-labeled when Issuers merge or get taken over - this happens for hundreds of card number ranges each month.

This means that Card Details constantly need to be checked and verified as the longer between checks, the more the accuracy of the data decays.

We source and verify information from as many sources as possible to ensure our data is as accurate as possible.

• Directly from the card networks
• Customers directly reporting IIN data to us
• Publicly available lists of card numbers
• Standards bodies
• Payment Processor partners
• Search data

Data is cross-referenced for discrepancies before being added to our database.

What we report on

We compile the following information for each card in our database:

• Card Network (e.g. Visa/Mastercard/AMEX)
• Card Type (e.g. Debit/Credit/Charge)
• If the card is a prepaid card
• Card Level (e.g. Gold, Platinum, Fuel card)
• Issuer Name (The name of the company/bank that gave out the card)
• Issuer Country (The country the Issuer operates in)
• Issuer Phone number
• Issuer Website address

Multiple levels

This website reports on the first 6 digits of the card number, but sometimes the network has allocated multiple Issuers card numbers within the 6-digit range.
For example, within the range '123456' the network could assign the prefix '1234561' to Issuer A and '1234567' to Issuer B. In cases like this, we can't accurately show the Issuer with just the first 6 digits, so we use the phrase 'Multiple' to indicate there are multiple values.
