Question 1

Is Card BIN Checker free?

Accepted Answer

Yes — completely free, with no registration, no rate limits and no premium tier. The site is supported by non-intrusive ads.

Question 2

Do I need an account?

Accepted Answer

No. Every tool works instantly without signing up — we never ask who you are.

Question 3

Do the tools work on mobile?

Accepted Answer

Yes. Every tool is designed mobile-first and works on phones, tablets and desktops.

Question 4

How accurate is the data?

Accepted Answer

BIN data is best-effort and provided for informational purposes only. It may be incomplete or out of date. If you spot an error, please tell us via the contact page.

Question 5

What is a BIN?

Accepted Answer

A BIN (Bank Identification Number), also called an IIN, is the first 6-8 digits of a card number. It identifies the card network, issuing bank, card type and country.

Question 6

What's the difference between a BIN and an IIN?

Accepted Answer

They refer to the same digits. 'IIN' is the newer ISO term; 'BIN' is the traditional name. Both are historically 6 digits, with 8-digit BINs now allowed.

Question 7

Is a BIN the same as the full card number?

Accepted Answer

No. The BIN is only the first 6-8 digits. The full card number (the PAN) is 12-19 digits. Our tools never ask for a full number to look up a BIN.

Question 8

Why does my BIN show no result?

Accepted Answer

New ranges are issued constantly and some small issuers aren't publicly documented. Try the first 6 digits and check for typos. A missing result doesn't mean the card is invalid.

Question 9

Can a BIN reveal the cardholder's identity?

Accepted Answer

No. A BIN identifies the bank, network, type and country only — never the individual account or cardholder.

Question 10

What does it mean for a card number to be valid?

Accepted Answer

Valid means structurally correct: the right length for its network and passing the Luhn checksum. It does not mean the card exists, is active, or has funds.

Question 11

Does valid mean the card works or has money?

Accepted Answer

No. This is a structural check only. We never verify live cards, account status or balances.

Question 12

What is the Luhn algorithm?

Accepted Answer

The Luhn (mod 10) algorithm is a checksum that catches most typos in card numbers. See the Luhn Checker for a step-by-step breakdown.

Question 13

Are the generated test cards real?

Accepted Answer

No. They are synthetic numbers that pass format checks but are tied to no real account and cannot be charged. They're for software testing only.

Question 14

Do you store my card number?

Accepted Answer

No, never. We don't ask for full card numbers, the BIN input is limited to 8 digits, and there are no accounts or trackers tied to what you type.

Question 15

Is anything I type sent to a server?

Accepted Answer

Only for the BIN Checker, and only the 6-8 digit BIN prefix — never a full card number. To identify a BIN we query a third-party lookup API first, then fall back to a database bundled with the site. Every other tool (validation, formatting, Luhn, network detection, test-card generation) runs entirely in your browser and sends nothing.

Question 16

Do you use cookies?

Accepted Answer

The site sets no first-party tracking cookies. Advertising cookies apply only when ads are enabled, subject to your consent — see the Cookie Policy.

Question 17

Is it safe to enter a card number here?

Accepted Answer

Yes. Full numbers are processed only in your browser, masked by default, and discarded when you leave the page — nothing is stored or transmitted.
