A credit card number that starts with 5424 is a Mastercard, not a Visa. Mastercard uses numbers beginning with 51 through 55, while Visa cards begin with the number 4. The 5424 prefix identifies the card's payment network, but it does not tell you the exact bank or card product.

The first digit of a credit card number helps identify its payment network. Mastercard traditionally uses numbers beginning with 51, 52, 53, 54, or 55. Since 5424 begins with 54, it falls within Mastercard's numbering range.
Visa cards, by comparison, begin with the number 4. Therefore, a card starting with 5424 is identified as a Mastercard rather than a Visa.
Not reliably. The first four digits can identify the card network, but more digits are needed to identify the issuing bank. The first six to eight digits are generally known as the Issuer Identification Number (IIN), also called the Bank Identification Number (BIN).
Even with the additional digits, the prefix does not reveal the cardholder's identity or account balance.
Here is a quick way to recognize some common credit card network prefixes:
These starting digits identify the payment network, not whether the card is a credit card, debit card, or prepaid card.
If your credit or debit card begins with 5424, it uses the Mastercard network. It is not a Visa card. The first four digits can help identify the network, but you need additional information to determine which bank issued the card.
Important: Never share your complete card number, expiration date, or security code when trying to identify a card.

A FICO® Score is a proprietary credit score created by the Fair Isaac Corporation (FICO). About 90% of top U.S. lenders use it to make lending decisions.
FICO® Score Ranges:
FICO categorizes scores as Poor, Fair, Good, Very Good, and Exceptional.
A credit score is a three-digit number (300–850) predicting your creditworthiness. Lenders use it to evaluate risk and determine rates and terms for credit.
Why it matters: A higher score can help you qualify for loans and lower interest rates. A lower score can lead to higher borrowing costs or application denials.
Note: Credit scores reflect your creditworthiness but do not guarantee approval for any credit product.
