Common questions
What is a BIN or IIN number?
A BIN (Bank Identification Number), also called an IIN (Issuer Identification Number), is the first 6 to 8 digits of a payment card number. It identifies the card network (such as Visa or Mastercard), the issuing bank, and the card program (credit, debit, or prepaid). Modern cards use 8-digit BINs under ISO 7812.
How many BIN ranges does CUSB BANK have on file?
CUSB BANK has 22 BIN ranges on file in UNITED STATES. Some issuers operate in more than one country; where that is the case this total may combine BIN ranges across all of them rather than a single country only.
How do I use a BIN number?
Enter the first 6 to 8 digits of any CUSB BANK-issued card into BINSearchLookup's free tool on the home page to instantly verify the card network, type (credit/debit/prepaid), and issuer. Merchants and payment processors use BINs for fraud screening, routing, and compliance checks.
Is this BIN data updated regularly?
BIN assignments change as issuers add or retire card programs. BINSearchLookup refreshes its dataset on a rolling basis from card network range registries and issuer disclosures. The last-verified date on this page reflects when it was last checked.
Can this page verify if a specific card is active or fraudulent?
No. A BIN identifies the issuer and card program, not an individual account or cardholder. To check whether a specific card number is valid in real time, use the free lookup tool or API on our home page. This page lists BIN ranges only.
Sources and limitations
BIN and issuer data on this page is aggregated from card network range registries and issuer disclosures, then cross-checked before publication. A BIN identifies the issuer and card program, not an individual cardholder or account, so this page cannot confirm whether a specific card is open, closed, or authorized for a transaction.
For real-time verification of a live card number, use the lookup tool or API on our home page. Full sourcing and update cadence are documented on the methodology page.
