Credit Card Type Detector

Identify the card network from a credit or debit card number. Detection uses IIN/BIN prefix matching to determine the issuing network.

How It Works

IIN/BIN Prefix Matching

Every card number begins with an Issuer Identification Number (IIN), also called the Bank Identification Number (BIN). The first 1-6 digits identify the card network and issuing institution.

Supported Card Networks

Network	IIN Prefix	Length
Visa	`4`	13, 16, 19
Mastercard	`51-55, 2221-2720`	16
American Express	`34, 37`	15
Discover	`6011, 644-649, 65`	16-19
JCB	`3528-3589`	16-19
Diners Club	`300-305, 36, 38`	14-19
Maestro	`5018, 5020, 5038, 6304, 6759, 6761, 6763`	12-19
UnionPay	`62`	16-19
Mir	`2200-2204`	16-19
Verve	`506099-506198, 650002-650027`	16, 19

Detection vs Validation

This tool detects the card type based on the number prefix. It does not validate whether the number is a real, active card. For full validation including Luhn algorithm checks, use the Credit Card Validator.
