Credit Card Type Detector
Enter a credit or debit card number to identify its likely network from the number prefix. The number stays in this browser.
A QUICK WALKTHROUGH
How to use this tool
- Enter digits with optional spaces or hyphens.
- Review the detected network and typical length range.
- Treat the result as a prefix match, not card validation.
Prefix detection only
The tool identifies a likely network from IIN/BIN prefix patterns and reports typical lengths. It does not run a Luhn check or confirm that a card exists, is active, usable, chargeable, or funded.
Local and ephemeral
Detection happens in this browser only. The entered number is not uploaded, stored, recorded, or logged by this tool.
GOOD TO KNOW
Common questions
Does this validate a card?
No. It detects a likely network from prefix patterns and does not verify the number, account, transaction, or funds.
Which networks are detected?
Visa, Mastercard, American Express, Discover, JCB, Diners Club, Maestro, UnionPay, Mir, and Verve.
Is the number sent anywhere?
No. Detection runs locally in your browser without uploading, storing, recording, or logging the input.
