600+ reviewsWhat is a BIN?
A Bank Identification Number (BIN), also known as the Issuer Identification Number (INN), is the first 6-8 digits of your credit or debit card’s Primary Account Number (PAN). It identifies the issuing bank or institution, the card network (such as Visa or MasterCard), and the card type (credit, debit, prepaid, etc.), and the geographic location of the issuing bank. Merchants and payment processors use BINs to detect potential fraud, comply with regulatory requirements, and ensure secure, accurate payment processing.
How the Primary Account Number Works
The 16-digit Primary Account Number (PAN) on your card is composed of:
- The Bank Identification Number (BIN): Identifies the issuing bank or institution.
- The Account Identifier: Links the card to your account.
- The Checksum Digit: Validates the PAN using the Luhn algorithm.
What Can You Learn from the BIN?
Our BIN Lookup tool provides insights like:
- Issuing Bank or Institution: Identify the financial institution responsible for issuing the card to ensure accurate transaction routing.
- Card Network: Determine if the card belongs to VIsa, MasterCard, American Express, or another network to apply the correct processing rules.
- Card Type: Understand whether the card is credit, debit, prepaid, or charge to manage transactions appropriately.
- Card Level: Learn if the card is standard, gold, platinum, or corporate, which can indicate spending limits or benefits.
- Geographic Location: Find the card’s issuing country or region, which helps in detecting unusual activity or fraud.
- Regulatory Compliance: Ensure cross-border transactions adhere to local financial regulations.
- Merchant Category Identification: Discover patterns in how and where the card is typically used to optimize fraud prevention and customer experience.

Frequently Asked Questions
Is a BIN lookup safe to use?
Yes. A BIN lookup only reveals the issuing bank, card network, card type, and country tied to the first 6 to 8 digits of a card. It never exposes the full card number, the cardholder's name, or any other personal or account details.
Can a BIN lookup show the cardholder's name or full card number?
No. The BIN only identifies the issuing institution and network, not the individual account. Merchants use this data to detect potential fraud and verify a card's origin, not to look up a specific person.
What is the difference between a BIN lookup and a BIN or card number generator?
A BIN lookup checks real, already issued BIN data to identify the issuing bank and network. It does not create new or usable card numbers. Chargeflow's tool is a lookup only, built for merchants verifying legitimate transactions, not a number generator.
How many digits are in a BIN?
Most BINs are 6 digits, though newer card formats use 8 digits as part of a 16 to 19 digit Primary Account Number.
How do merchants use BIN data to prevent chargebacks?
Merchants cross-check the BIN's country and issuer against the customer's billing and shipping details. A mismatch, like a US-issued card shipping to a different country with no prior order history, is a common early fraud signal, used alongside chargeback reason code tracking and broader chargeback automation to catch fraud before it becomes a dispute.
